ASTM A53 is a carbon steel alloy, which can be used as structural steel or for low-pressure pipelines.

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. A 53 is intended for pressure and mechanical applications and is also acceptable for ordinary uses in steam, water, gas, and air lines. Hot Rolled Square Steel Pipe

ASTM A53 Steel Pipe Specifications | CSCMP's Supply Chain Quarterly

A53 pipe comes in three types (F, E, S) and two grades (A, B). A53 Type F is manufactured with a furnace butt weld or may have a continuous weld (Grade A only) A53 Type E has an electric resistance weld (Grades A and B) A53 Type S is a seamless pipe and found in Grades A and B)

A53 Grade B Seamless is our most polar product under this specification and A53 pipe is commonly dual certified to A106 B Seamless pipe.

ASTM A53 seamless steel pipe is an American standard brand. A53-F corresponds to China's Q235 material, A53-A corresponds to China's No. 10 material, and A53-B corresponds to China's No. 20 material.

Production process Seamless steel pipe manufacturing process is divided into hot-rolled and cold seamless pipe. 1. Production process of hot-rolled seamless steel pipe: tube billet → heating → perforation → three-roller/cross-rolling & continuous rolling → de-pipe → sizing → cooling → straightening → hydraulic test → marking → seamless steel pipe with leverage effect detected. 2. Production process of cold drawn seamless steel tubes: tube blank → heating → perforation → heading → annealing → pickling → oiling → multiple cold drawing → blank tube → heat treatment → straightening → hydraulic test → marking → storage.

Applications 1. Construction: the pipeline underneath, the groundwater, and the hot water transportation. 2. Mechanical processing, bearing sleeves, processing machinery parts, etc. 3. Electrical: Gas delivery, Hydroelectric power fluid pipeline 4. Anti-static tubes for wind power plants, etc.
