ASTM A778 stainless steel pipe is used in low to moderate temperature applications. The specification is for unannealed, welded stainless steel materials.

JIS G3455 seamless steel pipe is mainly used for high-pressure piping. It has a high pressure bearing capacity and is suitable for pipelines that need to withstand high-pressure liquids.

ASTM A333 and ASTM A334 are both specifications for seamless and welded carbon and alloy steel pipes used for low-temperature service. Specifically, ASTM A333 covers a range of steel grades suitable for temperatures as low as -50°F (-45°C), while ASTM A334 is intended for temperatures as low as -150°F (-101°C).

ASME SA333 GR.6 seamless steel pipe is an American standard seamless steel pipe for low-temperature pipelines, which is used for low-temperature pressure vessel pipelines and low-temperature heat exchanger pipelines.
