What are the essential resource requirements for applying for a special equipment production license for factory-prepared pipe sections?
Thread Content
According to the \"Rules for Licensing Production and Filling Units of Special Equipment\" (issued on May 13, 2019), factory-prepared pipe sections refer to pipe component products that are welded and assembled by the manufacturing unit in a factory based on the construction design drawings before being shipped out as complete units; this does not include pipe prefabrication carried out by the installation unit at the construction site.
I really didn’t know there were so many strict requirements; most construction companies build a prefabrication plant around their temporary facilities, claiming to be practicing \"factory-based prefabrication\".
What you’re referring to is pre-fabrication of the project on-site; if it’s in a different location, then an application needs to be submitted, just like in the case of pressure vessels
There was once an order from the EU for \"factory-prepared pipes,\" and no domestic company was able to provide a quote, as it was not possible to determine the volume of work within the given deadline for quoting.
Things like this that can be valued, with a fixed unit price and an estimated total price

In that case, a thorough analysis is necessary, involving the estimation of work volumes based on similar projects; at the same time, limits for variations must be established, such as for variations in thick-walled pipes
The project is very complex; there is no mature manufacturing process involved, and it constitutes a pilot-scale industrial testing facility. As a result, foreigners are reluctant to take on the risks and prefer to pass on this troublesome task to suppliers, even if it means lower profits.
Factory-prepared pipe sections for component assembly devices 1. Establish a system. A quality assurance engineer is required to have an intermediate professional title. Equipped with personnel in design, materials, manufacturing processes, welding, heat treatment, non-destructive testing, pressure testing, physical and chemical analysis, inspection and testing, as well as equipment management. Among them, those responsible for design, technology, and welding must have a degree in a science or engineering field and hold the title of assistant engineer. If the requirements for the above professional titles are not met, it is possible to substitute them with a degree in science or engineering along with relevant years of work experience. 2. Technical personnel: not less than 5 people. 3. Non-destructive testing: RT or UT – no less than 2 personnel; 2 RT machines and 2 UT machines. If the enterprise conducts non-destructive testing on its own, there must be no fewer than 2 Level II personnel for each corresponding project. This can be outsourced. 4. Physical and chemical testing: There should be no less than 2 personnel responsible for mechanical and chemical analysis; chemical analysis instruments or quantitative spectroscopic analyzers are required, along with 2 portable hardness testers and 1 material testing machine. This can be outsourced. 5. Welders, not less than 6 persons. 6. Equipment: 1 submerged arc welder, 2 TIG welders or gas shielded welders, 1 pipe bending machine, 1 heat treatment furnace, and 2 electric heaters equipped with control cabinets. 7. Design capability: Can be outsourced
