Issues with equipment manufacturers assisting design institutes in drawing diagrams
Thread Content
I heard that for the pressure vessel drawings in some design institutes, the manufacturers assist with the design – how is quality ensured?
The original poster is mistaken: manufacturing and design should not be separated in the first place. The drawings produced by manufacturers are no worse than those made by design firms, after all, they don’t work in isolation. Abroad, it is handed over to the manufacturing plants. I recently went to a training session at the Special Inspection Institute, and the topic of abolishing design approvals for pressure vessels came up again. In China, there is a gradual shift towards assigning equipment design tasks to manufacturers – this is an overall trend.
Abroad, there is no such department as a design institute
What was said on the 2nd floor makes sense; the general trend is to leave the design work to the manufacturing plants. Of course, at the current stage there are still some poor-quality manufacturing plants whose design drawings are simply unacceptable
It’s normal; they also have the design qualifications
Ultimately, it is the design institute that signs off for approval...
If you’re worried, have a third-party testing agency conduct an inspection.
The integration of manufacturing and design has been discussed for several years, as the national conditions have not yet been determined.
We ask a design firm to draw the plans, which need to be sent to us for approval; once approved, we then approach a manufacturing factory to produce them :)
The manufacturing unit is responsible for design, drafting, and production; the design institute reviews the drawings, and production can only proceed once the design institute gives its approval
