09DG low-temperature pipe is a kind of seamless steel pipe, mainly used in low-temperature environments, such as low-temperature pressure vessels and low-temperature heat exchanger pipes. This kind of steel pipe has good impact toughness and low temperature performance, and can ensure safe operation under low temperature conditions of -45°C to -195°C.
The product specifications of 09DG seamless cryogenic tubes are generally 8-1240×1-200mm, and can also be produced according to 1/8" to 48"×SCH5S to SCH160, STD, XS, XXS and other standards. Its execution standard is GB/T18984-2003 or ASTM A333, and its material is 09DG1.
In order to make the cryogenic tube have better application value, other metal elements are usually added to improve its performance. During the manufacturing process, strict inspection and testing are also required to ensure that the quality and performance of the steel pipe comply with relevant standards and requirements.
