API 5L GB /ASTM A106B/ASME A53 GB

API 5L Grade B is a specification of the American Petroleum Institute (API) that defines the requirements for seamless and welded steel pipes suitable for conveying gas, water, and oil in the petroleum and natural gas industries. This grade of steel pipe has a minimum yield strength of 42,000 psi (290 MPa) and a minimum tensile strength of 60,000 psi (415 MPa). API 5L Grade B pipes are commonly used in pipeline transportation systems and are available in various sizes and wall thicknesses to meet specific project requirements. They undergo rigorous testing and inspection to ensure compliance with the API 5L standard and are known for their durability, reliability, and high-performance capabilities.
