Hello everyone, regarding the inspection of pressure vessels
Thread Content
Hello everyone. According to the relevant regulations, pressure vessels are generally subject to their first regular inspection within 3 years of being put into use, unless the product standards or the user entity deem it necessary to shorten the inspection interval. The date for the first regular inspection is proposed by the user unit at the time of applying for registration, and the registration authority determines it in accordance with relevant requirements. What I would like to ask is: What does the “commissioning” time refer to? Is it the time when the container started to be used? If I install the equipment but don’t use it, and only start using it after leaving it there for 3 years, when should the \"start date of use\" be calculated? When I went to register the use of the container, the quality supervision department calculated the period starting from the equipment’s date of factory inspection, which raised doubts for me. May I ask the expert: How should the timing for the first periodic inspection be determined?
One more question for everyone: Is it necessary to conduct an energy efficiency test of the boiler when applying for its use registration in the case of waste alkali incineration boilers?
This issue should have already been discussed on this forum...
Generally, the “commissioning” time refers to the date when the container starts to be used. If the device is not used after installation, it means it has not been put into use.
Only those who have actually gone through the registration process at the Quality Supervision Bureau understand this: the bureau doesn’t care when you use the product; it only looks at the certification stamp. Previously, there was at least an installation inspection stamp, but now that’s not the case anymore, so it’s simply the factory inspection stamp that matters. Thinking about it, it makes sense – you would do the same thing no matter where you are, as who knows when a company will start using the product? What if they wait several years before registering it? What if something goes wrong within three years of registration? To protect themselves, it’s necessary to have some kind of certification in place, so that in case of problems, the bureau can be held completely responsible...
It has been in use for three years; one should check whether there is any corrosion on the inner and outer surfaces. If so, the time required for the initial inspection should be reduced.
