LNG Terminal Cryogenic Alloy Steel Pipe from China
This is a longitudinally welded 9% nickel alloy steel pipe exceeding 406.4 mm in external diameter, designed for LNG tank vaporizers and transfer lines. Its circular cross-section and welded construction place it under tariff item 7305.31.00, which covers other welded tubes and pipes of iron or steel with circular cross-sections exceeding 406.4 mm. The 9% Ni grade provides cryogenic toughness.

Import Tips
• Verify the external diameter exceeds 406.4 mm and the weld is longitudinal for classification under 7305.31.00
• Provide material test certificates confirming the 9% Ni alloy grade and cryogenic impact properties
• Ensure compliance with Canadian standards for LNG service, such as CSA Z276 or ASME B31.3
