Seamless black steel pipe schedule 40
Black steel pipe refers to steel pipe that is not galvanized or otherwise surface treated, and its surface appears black or dark gray.
Seamless black steel pipe means that the steel pipe is made through processes such as billet heating, perforation, rolling and cooling, without welding joints, so it has better appearance and performance.
