Production process | Seamless steel pipe: perforated hot rolling process, no welds, |
Welded steel pipe: steel plate or steel strip curling welding, | |
Standard | ASTM A53: Pipes for conveying water, gas, and air |
ASTM A106: Seamless carbon steel pipes under high temperature and | |
ASTM A500: Cold forming welding and seamless pipes for | |
Surface treatment | The surface has a black oxide layer and requires further |
Application | Pipeline transportation, structural use, machinery manufacturing |
