API 5L Line Pipe

API 5L Line Pipe

Product Introduction :

Carbon Seamless steel pipe is used to transport fluid , such as the transportation of oil , natural , gas water and some solid material , such as pipe . And also can be used for various services such as onshore , offshore , shallow water and deep water , non-sour and services . The use of carbon seamless steel pipe manufacturing ring parts and improve material utilization , simplify the manufacturing process save materials and processing time , such as rolling bearing rings , jackets, etc . has been widely used to manufacture steel pipe .
