What flanges and gaskets are used for carbon disulfide pipelines?
What material is your pipeline made of? What are the operating conditions?
Use 20 seamless carbon steel for the pipes; temperature: 80, pressure: 0.6 MPa
The material of the flange isn’t entirely clear; in terms of structure, flanges with tenon-and-socket surfaces are generally more suitable as they provide better sealing. As for leaks, it’s important to use high-quality gaskets – modified polytetrafluoroethylene gaskets are good options, and graphite gaskets are also satisfactory. Of course, the strength of the bolts and flanges must be appropriate.
Reply to 3# tanny1221: Is carbon disulfide corrosive? What is the service life of carbon steel? Looking forward to a reply.
Reply to 5# tqg317: Carbon disulfide is corrosive; the service life of carbon steel is unknown, but it is designed to last around 50 years.
How can there be a design life of 50 years?
Reply to 7# 975569: About twenty-five years; 50 years is too long
