Requirements for constructing a non-destructive testing room for pressure vessels.
Thread Content
The company is now preparing to obtain the necessary certifications, and it needs to build a non-destructive testing room. However, it is not clear what equipment is required for such a room used for testing pressure vessels, what personnel are needed, and what requirements exist for constructing such a room Are there any other requirements? I hope all the sea friends can help by letting me know; thank you everyone.
No special design qualifications are required for the design, but it must be approved by the environmental protection department and a radiation license must be obtained. Barite should be used for the walls, while galvanized steel sheets should be used for the doors and roof. Indicator lights and signs must be installed, and waste liquid must be regularly collected by qualified entities. The area required depends on the actual production needs, but a larger area results in higher costs. The wall thickness is generally greater than 600 mm (depending on the radiation intensity), and the doors are steel-frame lead-plated doors. The thickness of the lead plate varies depending on the radiation intensity; the minimum thickness is greater than 6 mm, and it has passed the inspections conducted by health and environmental protection authorities.
Personnel: At least two Level 2 certificates for RT and UT are required; for MT and PT, at least one Level 2 certificate and one Level 1 certificate each are needed, as these are essential for generating reports. Equipment: Circular radiation machine, orientation machine, lead letters, and image quality agents. Ultrasonic simulators or digital devices, along with some sensitivity calibration blocks. Digital devices are more convenient to use, while simulators can be utilized for training future personnel. There are also yokes for magnetic particle testing, sensitivity test pieces, as well as cleaning agents, penetrants, developers, and sensitivity test pieces for penetrant testing. The lead rooms are inspected by the relevant authorities; the specific requirements are not very clear
Are there any relevant documents or regulations?
I knew it would need to pass the inspection by the environmental protection department, and that indicator lights and signs would have to be installed; I’m not sure about the other specific details
If the flaw detection room is built only for evidence collection and the actual flaw detection work is outsourced to qualified parties, then in my understanding, the above requirements are not necessary.
Since you are just starting to work with pressure vessels, I recommend that you download this book from here; it contains all the information you need. I hope the materials I have uploaded will be helpful to you. zhttp://bbs.hcbbs.com/thread-421410-1-1.html
Take a look: License requirements for the manufacture of boiler and pressure vessels
I would like to ask the experts: if I plan to outsource non-destructive testing, is it necessary to set up a flaw detection laboratory? The flaw detection rooms are so expensive; one costs 5 million+
It seems that it’s possible in some places, but is there an extra 0 in the 500w you mentioned?
I was previously involved in the process of applying for a qualification certificate for the company’s flaw detection laboratory, and I offer the following suggestions for reference. The qualification certificates for the flaw detection room consist of two parts: one is the radiation safety license ； The other is the completion acceptance of the radiation project. The specifics are quite complex: the qualifications of designers, occupational disease screenings, radiation safety training, various rules and regulations, testing and inspection equipment, environmental monitoring and dose alarm devices, records of cumulative doses, environmental monitoring, and so on. There are also requirements related to the application for the use of nuclear technologies. For detailed information, you can consult the relevant radiation management department at the local environmental protection agency; based on your radiation equipment, you will need to carry out the necessary tasks step by step, in accordance with the established requirements.
Another very important issue is the need to sign an agreement regarding the treatment and recycling of hazardous waste. In short, every aspect of the process – people, machinery, materials, methods, environment, and testing – is involved, haha
No, 500,000 is enough. For an ordinary X-ray machine, the penetration depth is around 60 mm
For 500w, how big a flaw detection room do you need to build! 1000 square meters?
