What are the specific requirements for rust removal, polishing, pickling, passivation, and degreasing of oxygen pipelines at 0.3 MPa? In which standards can these be found?
Thread Content
The standards provide general descriptions; specific material and construction requirements are needed
The specific requirements for rust removal, polishing, pickling, passivation, and degreasing of 0.3MPa oxygen pipelines can generally be found in the \"Code for Construction and Acceptance of Oxygen Pipelines\" as well as the \"Code for Construction and Acceptance of Pipelines in the Chemical Industry\". These standards provide detailed guidelines for pipeline treatment, including how to perform effective rust removal, the required levels of polishing, methods for pickling and passivation, and appropriate degreasing techniques. You can also refer to the \"Regulations on the Safety Management of Pressure Pipelines\", which may also contain relevant information. It is recommended to consult the latest version of the specifications for the most accurate guidance. .
Thank you very much for your reply, but this specification is too general; I’ve searched for a long time without finding anything
