Line pipe is a type of steel pipe that is used to transport petroleum, natural gas, oil, water, etc.

This pipe is available in a variety of diameters ranging from 2 inches to 48 inches and there are two product specification levels PSL 1 & PSL 2.

Line pipe can include either seamless or welded carbon steel or stainless steel piping. Because line pipe needs to withstand high pressures. There are important tests done on line pipe to ensure it meets all of the requirements of steel chemistry, strength, toughness, and dimensional characteristics. Using line pipe that meets the set criteria will ensure safe and reliable pipeline service.

The processing for welded line pipe includes ERW, LSAW, SSAW, DSAW, etc.

All welded pipe and seamless pipe will be supplied with mill test reports and full traceability as required.

And many grades of line pipe can be supplied, including API 5L-B, X-42, X-46, X-52, X-60, X-70, X-80, etc., manufactured according to standards of API 5L, ISO3183, ASTM A53, ASTM A106, ASTM A134, ASTM A135, ASTM A333, ASTM A335, etc.

In 2017 & 2018, we exported more than 10000tons LSAW to UZ National Oil Company.
