ASTM A312 TP317 welding stainless pipe introduction
ASTM A312 TP317L stainless steel welded pipe is an ultra-low carbon stainless steel with better resistance to intergranular corrosion and good heat resistance and corrosion resistance. The solution treatment temperature range is 1010~1150℃, followed by rapid cooling. Common welding methods include arc welding, argon arc welding, laser welding, etc. It is recommended to use AWS E317L/ER317L welding rod or wire during welding to ensure the corrosion resistance of the welded joint.

Advantages of ASTM A312 TP317L cold rolled electric welded tubing
ASTM A312 TP317L ERW Stainless Steel Pipe uses high-frequency current to instantly melt the edge of the steel strip and extrude it into shape. No filler metal is required. The production efficiency is 3-5 times higher than that of traditional arc welding, and the cost is reduced by about 20%. It can still maintain oxidation resistance (such as carburization and sulfidation resistance) at 600-800°C to avoid material softening or oxidation peeling.
ASTM A312 TP317L welded pipe application
Chemical industry: Treatment of corrosive waste gas or liquid containing Cl₂, HCl, H₂SO₄.
Marine engineering: Resistant to seawater splash and salt spray erosion, suitable for ship exhaust pipes.
Food and medicine: Resistant to corrosion by organic acids (such as citric acid, acetic acid) and disinfectants.
