P235TR1 vs P235GH
Jan 15, 2025
Both P235TR1 Seamless steel tubes for pressure purposes and P235GH Pressure Vessel Steel Pipe are low carbon steels that are widely used in different industrial applications.
P235TR1 conforms to EN 10216-1-2004 specification and belongs to seamless steel pipe for pressure bearing.P235GH conforms to EN 10028-2-2009 specification and belongs to steel pipe for pressure vessel. Under different specifications, the chemical element content and mechanical properties of the two types of carbon steel pipe, as well as the requirements of various treatments are very different, and thus there will be a big difference in the application.
