Kamron Pipe and Tubes, a well-respected manufacturer and supplier based in Bangkok, Thailand, specializes in high-quality Stainless Steel 347/347H Heat Exchanger Tubing. These tubes are crafted for outstanding performance in high-temperature and corrosive settings. With niobium added for stabilization, they effectively prevent intergranular corrosion even when exposed to heat for extended periods. The 347H grade, which has a higher carbon content, boasts exceptional creep and stress rupture strength, making it perfect for high-temperature applications. Kamron Pipe and Tubes is committed to precision engineering, durability, and adherence to international standards, ensuring they deliver reliable tubing solutions for critical heat transfer tasks.
The Stainless Steel 347/347H Heat Exchanger Tubing is made from a blend of chromium, nickel, and columbium (niobium), with carefully managed carbon levels to boost mechanical strength and thermal stability. These tubes showcase impressive tensile and yield strength, good toughness, and resistance to oxidation and scaling at high temperatures. Their advantages include excellent weldability, a long service life, high-temperature strength, and robust resistance to intergranular corrosion. The 347H grade offers enhanced creep resistance, making these tubes particularly effective for long-term heat exchanger applications in challenging environments.
