Bosega Pipes and Tubes is a reputable manufacturer and supplier located in Cape Town, South Africa, known for its top-notch Stainless Steel 316 and 316L Seamless Pipes. These pipes are celebrated for their outstanding corrosion resistance, making them a go-to choice in industries that demand durability and precision in tough conditions. Thanks to cutting-edge manufacturing processes and rigorous quality checks, Bosega Pipes and Tubes guarantees that each product meets international standards. The company serves a diverse array of sectors, including marine, chemical processing, oil and gas, and food industries, providing dependable and long-lasting piping solutions tailored to meet client needs.
Stainless Steel 316 and 316L Seamless Pipes are primarily made up of iron, chromium (16–18%), nickel (10–14%), and molybdenum (2–3%), which boosts their resistance to corrosion, particularly against chlorides and acids. The 316L variant, being low-carbon, offers better weldability and minimizes carbide precipitation. These pipes boast impressive tensile strength (515 MPa), yield strength (205 MPa), and elongation (40%), ensuring they perform exceptionally well under high temperatures and pressure. Their non-magnetic properties and excellent formability make them perfect for challenging industrial settings.
