Safety of elevators during power outages and sudden stops!
Elevator standards and safety
elevator. Standard, are designed in such a way that the brake is activated when danger occurs. So not moving and being stuck is a kind of reaction elevator It is to save your life. One of the reasons for these risks:
- Sudden power outage: which can be caused by a defect in the electricity company, the connection of electricity in the building and… to occur.
- Improper use: Sometimes the system elevator It is manipulated in some way. Such as riding over the capacity or forcefully holding the door open can cause it to stop.(Related)
- Mechanical and electrical defects: elevator As with other electrical and mechanical devices, it may encounter defects that, if such an event occurs, the cabin stops moving.
Elevator and escalator
In this article, we are going to make important and necessary points in time The sudden stop of the elevator to remind:
-
If the room elevator Trapped between floors, be sure to ask for the main power switch or fuse first elevator (Power board Or the same board ۳ phase on which there is only a zero, one and 3 small signal lights)be disconnected and then try to remove yourself.
-
Before taking passengers out of the cabin, definitely the cabin elevator bring it to the level of the floor because the passengers should not jump out of the cabin or be dragged out from the elevator door.!
-
Definitely after opening the door elevator With a special key! Make sure that the door is closed, don't forget that unfortunately most of the cases of people falling into the elevator shaft are due to the elevator doors being open..(Related)

بازرسی تجهیزات صنعت نفت و گاز
مخازن کروی در قالب مخازن تحت فشار ASME به منظور ذخیرهسازی مایعات و گازها در بسیاری از صنایع از جمله صنایع میاندستی، پاییندستی، petrochemical, chemical industries, refineries, etc … is used. These tanks can store many products such as dry ammonia, liquid gas, NGL, gasoline, naphtha, butadiene, ethylene, hydrogen, oxygen, nitrogen, argon, LNG, biogas and gas. Sewage save the.
Welding inspection and non-destructive tests (NDT)
The spherical shape of this Tanks It creates a uniform stress distribution during internal loading, which causes Storage under pressure It becomes more suitable. Spherical tanks take up the least amount of floor space for pressurized storage and require less foundation, lining, fittings, and piping costs than other options..
one Spherical tank After designing and determining the consumables and thickness, etc., they are divided into different parts. The size of these parts depends on the diameter tank And it also has factory equipment. if possible tank divided into fewer parts with more surfaces, in that case the amount of welding operation for Tank installation is reduced.
Third party inspection
Because most of these reservoirs are very thick (More than 25 mm) and are designed from almost high-strength steels and have a significant carbon equivalent, and as a result, their welding starts with preheating according to specific instructions and according to Instructions Special also ends and cannot be used for any part of tank At the discretion of a number of welders Welding operation In this case, uneven distribution of thermal stresses and residual stresses welding It causes assembly of other parts to break and even cracks in some welded parts.(Related)
Engineering inspection of oil, gas, petrochemical and refinery equipment
Obviously, due to the sensitivity of these tanks, all welds should be tested quality They make sure. method Test usually Radiographic test (Radiography Test) And Ultrasonic test (Ultrasonic Test) And M.T (Magnetic test)are. After the completion of the welding work, it is time to open the nozzles, according to the existing map, the location of the nozzles is first marked, and then the cut position is removed by the cutting machine, the nozzle is placed in the place, and after dimensional control and leveling, Spherical tank It is worth mentioning that the nozzles are usually welded using U.T and M.T methods (Magnetic test) It is tested.

It is the ninety-ninth meeting National Committee for Nanotechnology Standards It will be held virtually in May of this year Standard "Nanotechnology - considerations for conducting toxicokinetic studies with nanomaterials" Approved and ready for publication.
Nanomaterials are a family of chemicals that, like any other chemical, can cause a wide range of toxicity. Toxicokinetic science can:
- to measure safety Compounds including nanomaterials help by identifying potential target organs and the potential for persistence in organs.
- Used to assess whether a nanomaterial behaves differently from a similar nanomaterial or bulk material with a similar chemical composition..
- Describe the absorption, distribution, metabolism and excretion of foreign compounds in the body over time.
- relates exposure to internal dose; Therefore, it is one of the key dimensions for toxicity.
- Assist in the design of targeted toxicity studies and identify the potential of target organs and provide relevant information to justify or ignore toxicity studies..
- As a basis for grouping and review methods- useful nationwide.
Nano badge (Nano symbol)
A significant collection of published research articles, national and international guidelines, guides, etc National and international standards About the use of toxicokinetic methods to study the fate of chemicals in the body. But none of them deal with nanomaterials separately and some even specifically exclude nanomaterials.. for example, National Iranian Standard No. 21480, entitled "Toxicity Testing of Chemicals - Toxicokinetic Investigation - Guidance on Toxicokinetics", provides a detailed description for evaluating the toxicokinetic profile of chemicals, but clearly states that this guidance is for testing Nanomaterials Not considered, because toxicokinetic Nanomaterials It is different from dissolved ions and molecules and large particles.

Investment advice
Economic growth It is one of the main goals of every country Foreign investment As a suitable resource for accumulation capital And promotion of economic growth is considered to remove obstacles and facilitate absorption Foreign capital It is important and necessary to achieve this desire.
IranA country with a lot of capacity to absorb Foreign investment It is considered and of course for this reason it is the attention and luck of investors and the province Khorasan Razavi In its northeast, due to its many capacities, it has always been a leader in attracting foreign investment and has established itself as one of the most advantageous regions in the country..
The process of welcoming investors and approving foreign investment plans in Razavi Khorasan, even in the context of the spread of the Corona virus, showed that the stagnation in this field is meaningless and the prosperity and development in this fertile province is well underway and the actions and efforts are all in the same direction..(Related)
Khorasan Razavi is the leader in the number of foreign investment projects
The fertile region of Razavi Khorasan, with a 300 km border with Afghanistan and Turkmenistan, is also considered a north-south and east-west corridor, while this province is the entry point for the export of goods from Iran to the countries of Central Asia and vice versa..
This province has many capacities in the field of mines. Renewable energies, lands and agricultural products, animal husbandry, skilled labor and the availability of investment platform in industries.
Feasibility studies
Director General of Economic Affairs and Finance of Khorasan: This province is always in Attracting foreign investment In terms of the number of plans, the province has been the leader of the country, but in terms of figures Foreign investment Approved, due to the establishment of large projects in the area petrochemical In the south of Iran, it does not have the first ranks and these ranks belong to the southern provinces of the country.
Hossein Amirrahimi added: Therefore, this province has plans Investment There are many foreigners and with lower amounts in terms of investment, which has somehow facilitated the entry of capital into the province..
Prosperity and growth ۹۰ The percentage of investment in the corona situation
Director General of Economic Affairs and Finance Khorasan Razavi said: Last year, 75 projects from Razavi Khorasan province were submitted to the committee Foreign investment It was sent that out of this number, 59 foreign investment projects worth 131 million dollars were approved and received permission, according to which Khorasan Razavi ranks first in the country in terms of the number of foreign investment projects in the last year..
Amirrahimi added: This number of projects has grown by 90% compared to 2018, but in terms of the value of the amount of investment, due to the increase in medium and low investments, it has decreased by 7%..
He continued: In case of issuing licenses for all 75 plans sent from the province to the Foreign Investment Committee, we will see a 20% increase in the value of foreign investment..
Market Studies
This director of Khorasan Razavi Economic Area stated: It is expected that this year we will be able to attract 100 foreign projects worth at least 200 million dollars for Razavi Khorasan province, which will witness a revolution in this field..
Director General of Economic Affairs and Finance Khorasan Razavi said more without referring to statistics: In terms of investment value, the largest amount of capital is in the field of construction and housing, and in terms of acceptance in the field of industries, textile, clothing, leather and food industries are also most welcomed. Investors is placed.
A collection titled “Khorasan Razavi investment opportunities” By introducing 100 Investment opportunity In different economic sectors of the province, it has been prepared in 2 languages in electronic and paper format by the investment service center and is ready to be presented to investment applicants..
Afghanistan and Iraq investors ahead in foreign investment
Amir Rahimi pointing out that during the past years, many countries in the field investment Foreigners from Iran and Khorasan Razavi have arrived, he said: The diversity of the presence of investors from other countries is abundant, but some countries have shown their welcome and interest in this field from the past to the present..
Director General of Economic Affairs and Finance Khorasan Razavi said:In the meantime, Afghanistan, with 41 projects worth about 30 million dollars, had a 70% share in the number of investment projects in this province last year..
He continued: The investors of this country still have a lot of enthusiasm for the implementation of various investment projects in Razavi Khorasan due to the existence of good investment capacities, great trust and of course the high level of common issues and spiritual relations between the people of the two regions..

The difference between low emissivity nano glasses and other ordinary glasses
The difference between low emissivity nano glasses and other ordinary glasses
Nanotechnology
the glasses They are considered one of the most popular and practical building materials. One of the reasons for this popularity is the continuously developing thermal and optical performance of glass. One of the ways to achieve this function is to use Low emission coatings It is passive and solar controlled. Now the question is that Low emissivity glasses what is it To learn about this type of glass, we will first have a general look at the coatings.
In order to get to know the types of coatings, to know the spectrum energy Solar or energy emitted from the sun is important. Ultraviolet light, visible light and infrared light form different parts of the solar spectrum. The difference between these three parts is determined by their wavelength.
- Ultraviolet light, which causes the paleness of interior materials such as fabrics and wall coverings, has a wavelength of 310 to 380 nm..
- Visible light forms a part of the spectrum with wavelengths of about 380 to 780 nm.
- Infrared light (Thermal energy) It is transferred to a building in the form of heat and starts from the wavelength of 780 nm. Infrared light from the sun is commonly known as short wavelength energy, while heat radiation from hot bodies has longer wavelengths than the sun and is known as long wavelength infrared..
Nanotechnology Inspection
The main task Low emission coatings, minimizing the amount of ultraviolet and infrared light passing through the glass, without reducing the visible light passing through.
when Heat energy Either the light is absorbed by the glass, then it is transmitted by the movement of the air, or it is reflected again from the surface of the glass.. The ability of a material to radiate energy is known as emissivity. In general, materials with high reflectivity have low emissivity, and materials with a darker matte color have high emissivity.. All materials, including windows, radiate heat in the form of long wavelengths. energy The infrared wave depends on the emissivity and surface temperature of the material. Radiant energy is one of the most important methods of heat transfer that occurs through windows. Reducing the emissivity from one or more surfaces of the window glass improves the insulating properties of the window. به عنوان مثال شیشه بدون پوشش، گسیلندگی ۸۴درصد دارد، درحالیکه شیشه کنترل کننده خورشیدی Solarban® ۷۰XL تولید شده توسط کارخانه Vitro Architectural Glass (پیشتر با نام شیشه PPG شناخته شده بود) گسیلندگی ۲ درصد دارد.
این همان جایی است که پوششهای با گسیلندگی کم (یا شیشه های کم گسیل) بهکار میآیند. Low emissivity glasses پوشش شفاف و ابعاد میکروسکوپی دارند (به طوری که بسیار باریکتر از یک تار موی انسان هستند) که طول موج های بلند فروسرخ (یا گرما) را منعکس میکند. Some. Low emission coatings مقدار قابل توجهی انرژی فروسرخ خورشیدی با طول موج کوتاه را منعکس میکنند. در زمستان هنگامیکه انرژی گرمایی داخلی به جای سردتر در خارج منتقل میشود، پوشش کمگسیل، گرما را به داخل بازمیگرداند میکند و اتلاف گرما از طریق شیشه را کاهش میدهد. در تابستان، عکس این عمل رخ میدهد. به عنوان یک مقایسه ساده، شیشه کمگسیل مانند یک فلاسک عمل میکند. یک فلاسک دارای پوشش نقره است که دمای نوشیدنی را بازمیگرداند. دما به خاطر بازتاب ثابت و پیوسته ای که اتفاق میافتد یکسان میماند، همچنین از دیگر مزایای عایق سازی این است که فضای هوای به وجود آمده بین بدنه داخلی و خارجی فلاسک، مشابه عایقسازی شیشه است. چون شیشه کمگسیل شامل لایه بسیار نازک نقره یا مواد کمگسیل دیگری است، از مبنای علمی مانند مشابههمان فلاسک نوشیدنی است، یعنی پوشش کمگسیل نقره، دمای داخلی را به داخل بر میگرداند و اتاق را گرم یا خنک نگه میدارد.
انواع پوششهای کم گسیل و فرایندهای تولید آن
در واقع دو نوع پوشش کمگسیل وجود دارد: پوشش کمگسیل غیرفعال و دیگری پوشش کمگسیل با کنترل خورشیدی. پوشش کمگسیل غیرفعال، بهره گرمایی خورشیدی به یک خانه یا ساختمان را بیشینه میکند تا گرمایش خانه بدون نیاز به گرمای مصنوعی انجام شود. پوشش کم گسیل با کنترل خورشیدی به منظور محدود سازی مقدار انرژی گرمایی که به خانه یا ساختمان میرسد طراحی شده تا ساختمانها خنکتر بمانند و انرژی مصرفی، مرتبط با شرایط هوایی کاهش پیدا کند.
هر دو نوع شیشه کمگسیل غیرفعال و کنترل خورشیدی با دو شیوه اصلی تولید میشوند که شامل آذرکافت یا پوشش سخت و رسوبدهی خلا کندوپاش مگنترونی (MSVD) یا پوشش نرم. در فرآیند آذرکافت که در اوایل دهه هفتاد رایج شد، پوشش در حین تولید روی رشته شناور، بر روی نوار شیشهای اعمال میشود. سپس پوشش با سطح داغ شیشهای آمیخته میشود و پیوندی مستحکم و بسیار بادوام میسازد. در نهایت شیشه به ورقههای آماده در سایزهای متنوع برای حمل به کارخانهها بریده میشود. در روشMSVD که در دهه ۱۹۸۰ معرفی شد و به طور پیوسته در دهههای اخیر بهبود یافت، پوشش در دمای اتاق و در فضای خلا به شیشه قبل بریده شدن شیشه اعمال میشود.
به دلیل سیر تکامل تاریخی تکنولوژیهای پوشش، گاهی Low emission coatings غیرفعال با فرآیند آذرکافت و پوششهای کنترل خورشیدی با MSVD ترکیب میشوند. البته عملکرد از یک محصول به محصول دیگر و از یک کارخانه به کارخانه دیگر، به طور گستردهای متنوع است (جدول زیر را ببینید) ، اما جدول دادههای عملکرد به آسانی قابل دسترس است و ابزارهای آنلاین میتواند برای مقایسه تمام Low emission coatings موجود در بازار مورد استفاده قرار گیرند.
Standard and safety of nanotechnology
موقعیت پوشش
در یک پنل دوتایی استاندارد IG ، چهار سطح برای نشاندن پوشش وجود دارد. اولین سطح رو به بیرون است و دومین و سومین سطح رو به روی یکدیگر داخل یک قطعه شیشه عایق شده قرار دارند و بین آنها عایق هوا قرار دارد. همچنین سطح چهارم بهطور مستقیم رو به داخل قرار دارد. بهترین عملکرد پوشش کمگسیل غیرفعال زمانی است که روی سطح سوم و چهارم باشد (دورترین نقطه از خورشید) ، در صورتیکه بهترین عملکرد کنترل خورشیدی Low emission coatings زمانی است که روی نزدیکترین سطح به خورشید (به طورمثال سطح دوم) be.
اندازه گیری عملکرد پوشش کمگسیل
پوششهای کمگسیل بر سطوح متنوعی از قطعات شیشهای برای عایقسازی اعمال میشود. با وجود آنکه یک پوشش کم گسیل، غیرفعال و یا کنترل خورشیدی در نظر گرفته میشود، پیشرفتهایی را برای مقادیر عملکرد آنها در نظر میگیرند. موارد زیر جهت اندازهگیری اثربخشی شیشه با پوشش کمگسیل مورد استفاده قرار میگیرد:
مقدار U: درجۀ اتلاف گرمای پنجره.
- نور مرئی عبوری: مقدار نور عبور یافته از طریق پنجره.
- ضریب جذب گرمای خورشید (SHGC): کسری از تابش خورشیدی که از شیشه عبور میکند؛ چه میزان نوری که به طور مستقیم انتقال مییابد و چه نوری که جذب میشود و دوباره به داخل میتابد. هرچه ضریب جذب گرمای خورشیدی پنجره کمتر باشد، گرمای خورشید کمتری انتقال مییابد.
- جذب نور به گرمای خورشید: نسبت بین ضریب بهره گرمایی خورشیدی پنجره (SHGC) و نور مرئی عبوری آن (VLT).
هنگامیکه به طراحی یک پنجره فکر میکنیم اندازه، رنگ و ویژگیهای مربوط به زیبایی به ذهن میآید. but Low emission coatings نقش مهمی ایفا میکند و تاثیر قابل توجهی بر عملکرد پنجره، گرمایش، نوردهی و سرمایش کلی یک ساختمان دارد.(Related)

Technical inspection of the oil and gas industry
History The grand and national plan of the Gore to Jask pipeline It goes back to the 60s. At that time, that is, during the Iran-Iraq war, considering that alone Iran's oil export terminal He was on Khark Island and the enemy was well away Strategic and strategic Being aware of the existence of this terminal, he put this island under fire more than 2,840 times; While the number of days of war was 2 thousand 888 days. More than 2 thousand bombardment of Khark, alone Iran's oil export terminal; Always this feeling of need oil industry It has led to the fact that the occurrence of any unrest in the region will severely weaken Iran's export capacity. Especially, recently, the discussion of closing the Strait of Hormuz and the conflict between the Persian Gulf countries was also raised.(Related)

Head of Inspection and Technical Protection Department of Oil Engineering and Development Company (text) says: The Gore Jasak National Plan would not have been completed without internal capabilities. This project was able to set a huge chain of industries in motion with the long step taken to support domestic industries.
Gore crude oil transfer plan to JaskIt is a national and strategic plan with the support of the government and leadership National Iranian Oil Company and with the aim of creating a transfer capacity of one million barrels Crude oil in the day, Storage and export It through Jask's new terminalGuaranteeing the continuity of exports Crude oilDecentralization of Export Terminals and its diversification and sustainable development and job creation in Makran beaches is executed.(Related)
Third party inspection (Third party inspection)
Masoud Karbasian, CEO National Iranian Oil Company He stated that the national plan to transfer crude oil from Gore to Jask is the biggest project of Iran's oil industry: The production of transfer valves, the required electric pumps, the construction of 1000 kilometers of oil pipelines, along with the construction of tanks, terminals and floating spheres in the Jask region, using domestic power, shows the national determination to achieve this large and strategic plan..
He added: Gore project – Jask Due to sensitivities, several times in the stage of bed construction, pipe making, topkarani and so on… testpassed more than other projects without defects and with the best quality come to an end
Welding inspection and non-destructive testing
With the great step taken to support domestic industries, this project was able to move a huge chain of industries and affect a range of ore to pipes.. If I want to mention the non-technical achievements of this project in general, I must first mention the solution to the problem of providing pipes for the most strategic project of the country.. Providing this large volume of sheets and tubes with these economic conditions and under these oppressive sanctions was actually a difficult and even impossible task.. This inward look was able to find a solution to this challenge while preventing the outflow of huge amounts of currency. در ادامه باید به جلوگیری از خروج بیش از ۴۰۰ میلیون یورویی این طرح برای کشور از طریق ساخت تجهیزات در داخل کشور اشاره کنم که در حقیقت سرمایه بزرگ و دستاورد عظیمی است. مورد دیگر فعال شدن سرمایهها و امکانات موجود در داخل کشور است. شرکت فولاد اکسین خوزستان توانست با دستیابی به این فناوری مشکلات پیشین خود را پشت سر گذارد. کارخانه لولهسازی ماهشهر پس از سالها تعطیلی دوباره فعالیت خود را آغاز کرد. در حقیقت این نگاه به داخل سبب شد از طریق فعال کردن کارخانههایی که با این طرح همکاری میکردند چرخ بخش عظیمی از صنایع داخلی را به حرکت درآورد و از طریق ایجاد هزاران فرصت شغلی مستقیم و غیرمستقیم، نقشی بسزا در رشد و شکوفایی اقتصادی کشور ایفا کند.(Related)

What to do when there is a power cut in the elevator?
What to do when there is a power cut in the elevator?
Elevator and power cut
stuck in elevator Undoubtedly, it is a frightening experience. But the most important thing when stuck in the door elevator It is to keep your cool. In this article, we are going to remind you of some tips so that you can pass this scary and frightening experience safely.:
When locked in elevator Keep calm; Take a deep breath and don't panic so you don't panic others too because a few panicked people may do dangerous things in bad situations..(Related)
Some citizens think that if elevator If it gets stuck between floors, it faces the risk of falling. Therefore, there is an idea that a person trapped in an elevator should try to get out of the elevator as quickly as possible!If such thinking is completely wrong.
In case Elevator electricity It is disconnected and does not have emergency power, you can use the light of the phone for a short time, but you should not leave the phone on for a long time because the battery will run out; While it may be needed.
Elevator technical inspection
Telephone or alarm button (Alarm button) Push with the built-in bell shape inside the cabin to let others know someone is in elevator is stuck. If you have a mobile antenna, with the phone number inserted inside the elevator cabin, which includes the number of the guard or the building official. Elevator technical technician And finally, the fire department number is 125, call and wait for the rescuers to arrive while stating the exact address of the accident site.
You must know the situation you are in dangerous is not So instead of doing dangerous work, sit on the floor of the cabin. This way, when the elevator moves again, you will not lose your balance. Also, don't worry about the weather. Air in the well and Elevator cabin It flows and the oxygen your body needs does not run out.
