Bosega Pipes and Tubes, located in Cape Town, South Africa, stands out as a trusted manufacturer and supplier of Stainless Steel 347/347H Seamless Tubing. They specialize in providing precision-engineered solutions designed to thrive in high-temperature and corrosive environments. With a reputation for delivering top-notch stainless steel products, Bosega guarantees that every seamless tube adheres to strict dimensional tolerances and international standards. These tubes are perfect for critical sectors like aerospace, petrochemicals, thermal processing, power generation, and refinery systems, where dependable performance under stress and temperature changes is crucial.
Stainless Steel 347 is an austenitic chromium-nickel steel alloy that’s stabilized with niobium (or columbium), which helps prevent intergranular corrosion after welding and exposure to high temperatures. The 347H variant, with its higher carbon content, offers enhanced creep resistance and strength at elevated temperatures. The seamless tubing made from these grades boasts excellent resistance to oxidation, scaling, and high-temperature corrosion, along with solid mechanical properties and weldability. The seamless manufacturing process eliminates the weld seam, ensuring consistent strength and structural integrity, even in high-pressure and high-temperature conditions.
