Material list of the main pressure-bearing components of pressure vessels
Thread Content
In the factory documentation for pressure vessels, is the material list the original or a copy?
Even if you have the original, keep it for yourself; a copy will suffice.
In the factory delivery documents, the material list should be a copy, with the original kept for reference; moreover, one steel plate may be used in two pieces of equipment, so it is not possible to use the original for both of them.
Use a copy, stamped with the company’s special inspection seal.
It must be a copy; the original needs to be archived.
A copy; the original must be kept by your own company
Our province does not require a material list; just one comprehensive material sheet is sufficient
What does a material list refer to? If it is a warranty certificate, a copy can be issued upon leaving the factory.
I’ve never seen the original; it’s all photocopies with stamps.
