Line Pipes Bare & Coated

API Specification

Applications
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. We supply various line pipes including seamless line pipes (OD from 2-3/8" to 24", steel grade A, B, X42 - X80) and ERW line pipes (OD from 4-1/2" to 20", steel grade A, B, X42 - X80)..
