ASTM A53 seamless steel pipe refers to the foreign standard steel pipe grade, that is, the American sign. A53-F corresponds to domestic q235 material, A53-A corresponds to domestic 10# material, and A53-B corresponds to domestic 20# material.
ASTM A53 (ASME SA53) carbon steel pipe is a specification that covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8″ to NPS 26.
A53 Grade B Seamless is our most polar product under this specification and A53 pipe is commonly dual certified to A106 B Seamless pipe.
