I have a question regarding the butt welding of pipes or pipe fittings, and I’d like to ask everyone for their opinions

Thread Content

When it comes to welding pipes or welded pipe fittings during the process of pipeline connection, generally the outer diameters and inner diameters are not identical, nor is the wall thickness the same; at the site, beveling can be used as a solution to this issue. But I would like to ask everyone: at what extent of difference in diameter, or at what level of inconsistency in wall thickness, cannot butt welding be performed? Are there any standards that can be checked?
