Low Temperature Pipe

ASTM A333 Low Temperature Pipe Supplier

We supply Seamless A/SA333 Grade 1/6 Pipe for your Low Temperature Service applications. We offer seamless and welded steel pipe. Contact us if you need help with a specific carbon steel pipe request.

Our low-temperature carbon steel pipes are low- to medium-carbon (0.20 to 0.30%), high-manganese (0.70 to 1.60%), silicon (0.15 to 0.60%) steels, which have a fine-grain structure with uniform carbide dispersion. Our LTCS pipe features moderate strength with toughness down to — 50°F (—46°C). ASTM A333 covers nominal wall seamless and welded carbon pipe. ASTM A333 Grade 6 Low Temp Seamless Carbon Steel Pipe is an alloy steel with similar properties as AISI 4032 steel.
