Product Description

The Low Temperature Service Stainless Steel High Pressure Pipe, ASME SA358, is engineered to deliver unmatched performance, safety, and reliability in demanding cryogenic and high-pressure applications. This product is specifically manufactured to meet the stringent requirements of ASME SA358 for welded austenitic stainless steel pipe, ensuring exceptional toughness and structural integrity at temperatures as low as -320°F (-196°C) and beyond. It is the definitive solution for industries where failure is not an option, providing a robust barrier against extreme pressures and low-temperature embrittlement.

Attribute	Details / Specification
Standard	ASME SA358
Material Grades	ASTM A312 TP304/304L, 316/316L, 321, 347
Manufacturing Process	Automatic Fusion Welding, Seamless (for comparable spec)
Size Range	1/2" to 24" NPS
Schedule Wall	SCH 5S to SCH XXS
Low-Temp Service	Down to -425°F (-254°C) for designated grades

Constructed from premium austenitic stainless steel, the ASME SA358 high-pressure pipe inherently possesses excellent corrosion resistance. Its primary differentiator is its superior low-temperature service capability. The carefully controlled chemical composition and welding process stabilize the austenitic microstructure, preventing ductile-to-brittle transition and maintaining high impact strength (Charpy V-notch tested) even in deep cryogenic environments. This stainless steel pipe is designed for high-pressure fluid and gas transfer, featuring a consistently smooth, uniform weld bead that minimizes turbulence and meets stringent hydrostatic and non-destructive examination (NDT) standards like RT (Radiographic Testing).

Key Advantages & Applications:

The ASME SA358 pipe offers critical advantages, including exceptional low-temperature toughness, superior weld integrity verified by NDT, high corrosion and oxidation resistance, and excellent dimensional accuracy. These selling points make it indispensable for applications in LNG (liquefied natural gas) processing and transport, cryogenic storage systems, industrial gas production (oxygen, nitrogen), chemical processing plants handling refrigerated media, and sophisticated high-purity or vacuum line systems.

Production & Service:

Our Low Temperature Service Stainless Steel Pipe is produced using state-of-the-art automatic fusion welding technology under controlled atmospheric conditions, ensuring a homogeneous, fully consolidated weld zone. Each production batch undergoes rigorous quality verification. We provide comprehensive technical data sheets, material test reports (MTRs) certifying compliance with ASME SA358, and professional support for material selection and specification review.

Q: How does the ASME SA358 pipe perform in low-temperature service compared to seamless pipe?

A: When produced to SA358 specifications with proper welding and heat treatment, the welded pipe offers low-temperature mechanical properties comparable to seamless pipe for many applications, with the added benefit of larger available diameters.

Q: What NDT is standard for this product?

A: Full-length radiography (RT) is the standard NDT method per ASME SA358, ensuring 100% weld integrity inspection for high-pressure and low-temperature service reliability.
