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.

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.
