Problems with pipeline welding
Thread Content
It is being carried out on-site, and as a process engineer, I’m not sure whether this approach is appropriate. I would appreciate guidance from the experienced experts in this forum. The original pipe wall thickness was 10, while the wall thickness of the tee purchased now is 12.7. Can they be welded together? Combustible gas pipeline, pressure 3.2 MPa, temperature 220°C. The construction party said that welding can be done after grinding the groove. Are there any standards or requirements? I hope the experienced members of this forum can give me some guidance!

Sure. If the two thicknesses are different, edge trimming can be carried out in accordance with GB150.4-P325
