Nestled in the industrial landscape of Naypyidaw, Tun Pipes stands as a dedicated manufacturer and supplier of high-performance duplex stainless steel welded tubing. We understand that the integrity of your project hinges on the quality of its components, which is why we are committed to providing robust tubing solutions crafted to meet the demanding standards of modern industry. Our expertise lies in delivering products that offer a superior blend of strength and corrosion resistance, ensuring long-term reliability for our clients across Myanmar and beyond.
The composition of duplex steel welded tubing combines the best of both worlds, typically featuring a blend of chromium, molybdenum, and nitrogen. This unique formula results in exceptional mechanical properties, including very high strength and outstanding resistance to corrosion, particularly from chloride-induced stress corrosion cracking. This material is markedly stronger than standard austenitic stainless steels, offering a significant advantage in applications where weight savings and structural integrity are paramount concerns.
