Seamless Pipes for Cryogenic Applications: LNG and Liquid Hydrogen Transport

Date:2025-03-19

Cryogenic pipelines require ductile, impact-resistant seamless pipes to transport liquefied natural gas (LNG) and liquid hydrogen (-253°C).

Low-Temperature Steels: ASTM A333 Gr. 6, 9Ni Steel, and Austenitic 304/316L resist embrittlement at -196°C to -253°C.

Charpy Impact Testing: Ensures fracture toughness under extreme cold conditions.

Weld Seam Elimination: Seamless construction reduces brittle fracture risk in cryogenic storage and transfer pipelines.
