Seamless steel pipe for low temperature resistance is a steel pipe product which would be used in special environment. It is requested that the end product should have good impact toughness in low temperature environment (usually lower than -45℃ ). To guarantee it would not be Low-temperature brittle fracture in using process. The Changbao brand low temperature steel tube product category is nearly covered covers all the low-alloy Steel Grades in ASTM A333/A334. Meanwhile, As Changbao is the professional manufacturer of OCTG, we could also supply low-temperature environmental API 5CT standard steel grade products for satisfying different requests of intensity in use by customers and providing the best pre—sales & after-sales service for customers.

Product features

The Changbao brand seamless steel pipe for low temperature resistance is made by high purity steel of low sulfur & phosphorus and treated by calcification. It could effectively decrease the Low-temperature brittle fracture and promote the impact toughness of products. Our company has been equipped the Cooling Tank of 0～-100℃, we are capable to do the batches of low-temperature impact tests and guarantee the stability of the quality of our products.

Application Environment for Products

The ASTM A333 and A334 low temperature resistant tube is mainly used in low temperature pressure vessel pipeline and heat exchanger pipeline which is in temperature between -45℃ to195℃, it can also be used for cryogenic environment of fluid transmission pipeline. The low temperature casing of API 5CT is mainly used in the oil drilling & exploitation in the extreme cold zone.
