Oil pipe line API 5L ASTM A106 A53 seamless steel pipe

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. A53 is intended for pressure and mechanical applications and is also acceptable for ordinary uses in steam, water, gas, and air lines. 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)
Product introduction
ASTM A53 Grade B Seamless is our most popular product under this specification and A53 pipe is commonly dual certified to A106 B Seamless pipe.

ASTM A53 Grade B is the material under the American steel pipe standard, API 5L Gr.B is also the American standard material, A53 GR.B ERW refers to the electric resistance welded steel pipe of A53 GR.B; API 5L GR.B Welded refers to the material Welded steel pipe of API 5L GR.B.

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.
