If possible, what should be taken into consideration? What about pressure vessels that are not classified, namely vessels at atmospheric pressure? If it’s not allowed, which rule is being violated? Thank you!
No, it is necessary to obtain the consent of the original design unit. The manufacturing unit can write down the changes it needs to make and contact the original design unit; after communication and once the requirements are met according to the standards, the design institute can issue its approval stamp.
Dude, which one do you still want to ask about? If that’s the case, then the drawings produced by the design institute are nothing but worthless paper; after all, they can be changed freely without the need for the design institute’s approval, which is quite ridiculous
Remember one thing: change orders also need to be stamped with the TSG seal.
I know that. Does it have to be the original design firm?
That’s a good question: regardless of whether it’s yellow or not, the original design agency should be responsible for the product drawings it designed (during the design lifespan)； If it explodes in the future, we cannot fail to hold him accountable just because he was previously at fault. But for products in production, the cycle is generally not long, right? Won’t they go bankrupt just one or two weeks after designing a good product? Applying for bankruptcy also takes time to get approved. If the original design firm suddenly disappears (let’s say), then one has no choice but to accept that situation and hire another firm to carry out the redesign.
