Advantages of ASTM A312 TP304L Stainless Steel ERW Pipe
ASTM A312 TP304L welding sanitary tubing adopts automatic orbital welding process (TIG welding), with uniform welds and no pores and slag inclusions, ensuring smooth and continuous inner surface, and meeting sanitary fluid transportation standards.
ASTM A312 TP304L cold drawn welded pipe is acid and alkali resistant, high temperature resistant (-20℃~430℃), suitable for chloride ion environment and high temperature sterilization scenarios; low carbon components effectively improve the ability to resist intergranular corrosion, extend the service life of the pipeline, and reduce maintenance costs.
