A333 Grade 6 pipe is a steel pipe material specially designed for low temperature environment. It can maintain good mechanical and physical properties under low temperature conditions to ensure safe and reliable use in low temperature engineering. In low temperature environment, the toughness of the material is crucial. Low temperature steel pipes need to have sufficient impact toughness to prevent brittle fracture at low temperature. Low temperature steel pipes are widely used in petrochemical, nuclear industry and other fields. Its production process is complicated and requires multiple links such as smelting, rolling, cold working and heat treatment.

Application Fields of Low Temperature Steel Pipes

Energy Field
Widely used in the liquefied natural gas (LNG) industry chain. From LNG production, storage to transportation, low temperature steel pipes are indispensable. At LNG receiving stations, pipelines used to connect LNG storage tanks and gasification devices, as well as pipeline systems of LNG transport ships, require cryogenic steel pipes.
Chemical Field
In the chemical industry, some low-temperature reaction processes require the use of low temperature steel pipes. For example, in the deep cold separation process of synthetic ammonia, the temperature can be as low as -196°C. At this time, ultra-low temperature steel pipes are required to transport low-temperature media to ensure the smooth progress of the reaction process.
Refrigeration and Air-conditioning Field
In the low-temperature parts of large refrigeration systems and air-conditioning systems, such as refrigeration pipes in cold storage, low-temperature pipes of chillers in large air-conditioning systems, etc., low temperature steel pipes are used to transport low-temperature refrigerants to ensure the normal operation of the system.
