S355 ERW steel pipe is a low-alloy structural steel high-frequency straight seam resistance welding steel pipe. The high-frequency straight seam welded pipe is the same production welding process, but it is different from the ordinary welded pipe welding process. The weld is formed by melting the base material of the steel strip body, and the mechanical strength is better than that of the general welded pipe.
Standard: API, ASTM , API 5CT, API 5L, etc
Grade : A53(A,B), Q235, Q345, Q195, Q215, St37, etc
Length:3-12m or requirement

WT:0.6 - 30 mm
S355 ERW steel pipe usually produces small diameter, high welding speed, small welding heat-affected zone, welding can not clean the workpiece, and can weld thin-walled pipes and welded metal pipes, widely used in bridges, ships, power stations, boilers, pressure vessels, petroleum Storage tanks, lifting and transportation machinery, etc.
