Advantages of ASTM A312 TP309S cold rolled electric welded tubing
ASTM A312 TP309S stainless steel ERW pipes supplied by GNEE are made of austenitic material, with better corrosion resistance and heat resistance than 304 stainless steel. They are suitable for high temperature, high pressure and corrosive environments, and ensure zero leakage of the medium through precision processes. The specifications are 57-1626mm in outer diameter and 1.2-60mm in wall thickness, which can meet different strength requirements. It has strong resistance to thermal deformation and can operate stably at high temperatures of 980℃, suitable for high-temperature equipment such as boilers and chemicals; it is resistant to chloride ion corrosion and is suitable for seawater treatment, shipbuilding and other scenarios, effectively reducing maintenance costs.
