Difference between black steel pipe and carbon steel pipe
In general, black steel pipe and carbon steel pipe have about the same procedures for welding. That is if you are talking about general welding and not for some specific application like very cold temperatures. Black steel pipe is not really a specification but rather a generic term used primaril...Read more -

Seamless steel pipe piercing
Piercing is the first step of hot-rolled seamless steel pipe deformation, and its role is to solid hollow tube billet dressed as capillary. Due to wear a capillary surface defects or eccentric (uneven thickness) is difficult to eliminate or reduce the deformation process, therefore, the quality o...Read more
