2. Recommended Description

ASTM A334 Seamless Steel Pipes for Low-Temperature Service

ASTM A334 is a U.S. standard for seamless and welded carbon/alloy steel pipes designed for low-temperature environments (down to -45°C/-50°F). These pipes are widely used in cryogenic applications, LNG plants, and refrigeration systems where toughness at subzero temperatures is critical.

Key Features & Applications:
 Cryogenic Performance - Certified for impact testing at -45°C (Grade 6/8).
 Material Versatility - Grades 1 (carbon steel) to Grade 8 (alloy steel) for varying temperature needs.
 Global Compliance - Matches DIN 17175 and EN 10216-2 for European projects.
 Reliable Packaging - Anti-rust coatings and bundled with end protectors.

Industries: Oil & gas (LNG), petrochemical, refrigeration, and cryogenic storage.
