A friend’s factory needs to be connected to the park’s high-pressure steam network, with a pressure of 3.6 Mpa. To enable access to this network, a temperature and pressure reducing device will need to be installed. The design firm has already prepared the drawings; I would like to ask the experts in the field of pressure pipelines whether it is necessary for the design firm to provide additional drawings, and whether those drawings need to be filed with the relevant authorities Are there any simple ways to do it? Thank you
A document needs to be prepared and stamped; registration is probably not required
I just asked a colleague in the pipeline valve field, and he said that it’s necessary for the design institute to prepare the drawings and affix their seal, and it also needs to be registered with the quality supervision agency. It’s so troublesome
Registration isn’t very complicated; it just involves submitting some documents. Nowadays, the service attitude of the **department is also very good
