Line pipe

 Line pipes are used to transport oil and gas, water, mineral slurry and other fluids. Our line pipes are manufactured in accordance with API Spec 5L. Tubing and Casing, Line Pipes API SPEC 5L is a international standard specifies requirements for the manufacture of two product specification levels (PSL 1 and PSL 2) of welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries.
