Application of ASTM A53 seamless carbon steel pipe:
ASTM A53 seamless pipe is a carbon steel pipe, divided into two types: A53 A and A53 B. A53 A material has relatively low chemical composition requirements and is suitable for low-pressure applications under general working conditions. A53 B material requirements are relatively high and can be used in pipeline systems under high temperature and high pressure. A53 material seamless pipe is suitable for petroleum, natural gas, chemical industry and other fields, and is widely used to transport liquids and gases. 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 seamless carbon steel pipe production process:
Seamless steel pipe manufacturing process is divided into hot-rolled and cold drawn 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.
