carbon steel seamless pipe
Seamless (SMLS) steel pipe is made of tube blank or solid ingot, and then through hot rolled or cold rolling / drawn process to finish the final pipe specification, without weld, with average wall thickness, which can bear middle & high pressure and also can use in bad condition environment.
The seamless steel pipe mainly used for pressure vessel and conveying fluid such as transporting oil, natural gas, coal gas, steam, water as well certain solid material, etc.
