ASTM A106/ASME SA106 is the standard specification for seamless carbon steel pipe applied for high temperature services. It includes three grades A, B and C, and common use grade is A106 Grade B. It used in different industries not only for pipeline systems like oil and gas, water, mineral slurry transmission, but also for boiler, construction, structural purposes.

Package of carbon steel seamless pipe

Plastic caps plugged at the two sides of pipe ends

Should be avoided by the steel strapping and transport damage

Bundled signs should be uniform and consistent

The same bundle(batch) of steel pipe should be came from the same furnace.

The steel pipe has the same furnace number, the same steel grade, the same specifications.
