What is ASTM A312 pipe?
What is ASTM A312? ASTM A312 is a specification for seamless and welded austenitic stainless steel pipes that perform well in high temperature and corrosive environments. The common grades for this specification are 304/304L and 316/316L.
Is EFW pipe seamless?
ASTM A312 Stainless Steel This is a seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service.
Is HFW the same as ERW?
ERW is the general term for electric resistance welded steel pipe. It can be divided into two types: alternating current welding (AC) and direct current welding (DC). High frequency welding (HFW) is mainly used for ordinary or thin-walled steel pipes. It includes contact welding and induction welding.
What is the difference between EFW and ERW pipe?
ERW steel pipe is the abbreviation of electric resistance welding. The weld of the high-quality ERW welded pipe can reach the same level of toughness as the base metal, which cannot be achieved by the submerged arc welding process. EFW steel pipe is the abbreviation of electric fusion welding.
