The outlet pipeline of the safety valve for the steam pipeline was designed by the design institute as a pressure pipeline; is it necessary to register it according to the catalog of special equipment?
If the outlet pipeline of the steam pipe safety valve meets the definition of a pressure pipeline as specified in the \"Catalogue of Special Equipment\" (maximum operating pressure ≥ 0.1 MPa gauge pressure, medium is steam, nominal diameter ≥ 50 mm), and it does not fall under the category of \"pipelines associated with the equipment itself\" or under any exemption provisions, then it is considered a pressure pipeline and must be registered as a special equipment item and subject to supervision.
The design units have already designed them as pressure pipelines; isn’t it redundant to ask again? Besides, he has the design drawings; won’t they be inspected according to those drawings during the acceptance process?
