A312 TP304L ERW Stainless Steel Pipe
GNEE sells over 1,500 tons of seamless and welded steel pipes to various engineering industries every year. Our goal is to ensure that our customers have the highest expectations for the delivery and product quality of ASTM A312 P304L stainless steel pipes.
ASTM A312 covers seamless, straight seam welded and heavily cold worked welded stainless steel pipes, allowing welding of two longitudinal sections when welding larger diameter pipes. A312 TP304L stainless steel welded pipe has excellent corrosion resistance and good manufacturability, and A312 304L ERW pipe is used for high temperature and general corrosive conditions.
A312 stainless steel 304L welded pipe produces less carbide precipitation during welding and does not form too much intergranular corrosion, while having a high working temperature, so it can be applied to high temperature services. The working temperature is up to 870 degrees Celsius.
