API 5L Carbon Steel Pipe

API 5L pipe is a carbon steel pipe used for oil and gas transmission. They include seamless and welded (ERW, SAW) manufactured pipes. These ratings include API 5L Class B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1 and PSL2 Onshore, Offshore and Sour Service. API 5L is the executive standard and line pipe specification for steel pipes used in pipeline transportation systems. API 5L is a specification for seamless and welded carbon steel pipe materials. API 5L pipes are widely used in the pipeline industry to transport oil, water and gas. Depending on strength, schedule and service requirements, API 5L pipe can be manufactured in various grades for both onshore and offshore applications. In this article, we will learn about the various grades, specifications and schedules of API 5L pipe. API 5L pipe for the oil and gas, water and petrochemical industries is available in two Product Specification Levels (PSL) based on quality level. The first is PSL1, which provides standard quality levels. Another PSL2 provides additional mandatory requirements in terms of strength, chemical composition, NDT or notch toughness.
