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.
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.
