Quality inspection for the installation of buried pipelines
Thread Content
Hello, experts. What are the quality inspection requirements for the installation of the plant’s water supply and drainage pipes in a chemical plant, specifically for those pipes that are buried underground? Winter is approaching here, and work cannot proceed any longer. However, part of the circulating water pipeline installed earlier has already been completed. What aspects of quality inspection need to be carried out now, and are signatures from the construction party, the supervision party, and the client required?
Segmental acceptance is carried out, which requires a hydrostatic test (under the supervision of the supervisor); once the test is successful, rust removal and anti-corrosion treatment are applied to the weld seams, followed by electrical spark testing of the anti-corrosion coating, with signatures from the relevant parties required for confirmation.
What was said upstairs is very accurate; the most important thing is the pressure test. Reputable construction companies and supervision firms have corresponding documents and forms, as well as a range of materials such as construction technical measures, records of concealed works, and test plans. The owner should stay informed and oversee the process.
