API 5L GR. B PSL 2 Pipe
The American Petroleum Institute specification API 5L covers seamless and welded steel line pipe. This is steel pipe for pipeline transportation systems in the petroleum and natural gas industries. API 5L is suitable for conveying gas, water, and oil. Size range is limited only by manufacturer’s capabilities.
Specifications for API 5L adhere to the International Organization for Standardization isO 3183, which standardizes pipeline transportation systems within the materials, equipment and offshore structures for petroleum, petrochemical, and natural gas industries. The technical committee authoring the standards recognized that there are two basic Product Specifications Levels (PSL) of technical requirements and therefore developed PSL 1 and PSL 2. PSL 1 is a standard quality for line pipe where PSL 2 contains additional chemical, mechanical properties, and testing requirements.

API 5L X42 PSL1 Steel Pipe
API 5L X65 PSL1/2 Pipes Application-
Carbon Steel is used in the most critical engineering applications and also in certain applications in the automotive sector. In addition, some of the value-added Carbon Steel products include steel for LPG cylinders, API grade, corrosion resistant steel, critical structural application steel, boiler quality, auto grades, precision tubes and medium/high carbon grades, among others.
Specification for line pipe API SPEC 5L (-09): specifies the requirements for the manufacture of two product specification levels (PSL1 and PSL2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries.

API 5L X52 PSL1 Pipe
API 5L X52 Pipes are specially designed to handle the transportation of oil and gas under high pressure and temperature conditions. The production of these pipes places a strong emphasis on toughness and impact resistance, particularly for sour service and other demanding applications. Due to the high levels of sulphur present in sour wells, these pipes are particularly susceptible to stress corrosion. To mitigate this, manufacturers often apply anti-corrosion coatings such as oil, varnish, or black paint to the surface of the pipes. This additional layer of protection helps to enhance the corrosion resistance of the pipes, ensuring their longevity and reliability in harsh environments.
API 5L X52 is a specification for pipeline steel pipes that are used in the transportation of oil and gas. The API 5L X52 specification covers both seamless and welded pipes and includes requirements for chemical composition, mechanical properties and dimensions such as pipe wall thickness, outer diameter and pipe schedule. The pipe is known for its high yield strength of 52,000 psi and is suitable for high-pressure applications. It has an equivalent ASTM specification A53 Grade B and EN10208 L360MB or GB/T9711 L360 and isO3183 L360 as grade.

API 5L X70 PSL2 Pipe
Carbon Steel is used in the most critical engineering applications and also in certain applications in the automotive sector. In addition, some of the value-added Carbon Steel products include steel for LPG cylinders, API grade, corrosion resistant steel, critical structural application steel, boiler quality, auto grades, precision tubes and medium/high carbon grades, among others. Specification for line pipe API SPEC 5L (-09): specifies the requirements for the manufacture of two product specification levels (PSL1 and PSL2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries.
