Bosega Pipes and Tubes, based in Cape Town, South Africa, specializes in providing top-notch **Carbon Steel API 5L Grade B Pipes**. These pipes are engineered for the safe and efficient transport of oil, gas, water, and various other fluids within industrial pipeline systems. They meet the standards set by the American Petroleum Institute’s API 5L specification and are commonly utilized in both onshore and offshore pipeline projects. With a Grade B rating, these pipes boast a minimum yield strength of 35,000 psi, making them ideal for moderate-pressure applications while offering excellent weldability and formability.
Carbon Steel API 5L Grade B pipe is primarily made of iron, carbon, and trace amounts of manganese, phosphorus, and sulfur, providing a balance of strength and ductility. This pipe exhibits mechanical properties, with a minimum of the yield strength is 245 MPa and the tensile strength is about 415 MPa. suitability for application. The advantages of API 5L Grade B pipe include excellent weldability, internal corrosion resistance, and compatibility with harsh work environments. Compliance with stringent API standards ensures the reliability and safety of delivering oil, gas and other liquids to a variety of industrial applications.
