Tun Pipes, a trusted manufacturer and supplier based in Naypyidaw, Myanmar, stands as a key provider of high-strength pipeline solutions. We specialize in producing Carbon Steel API 5L Grade X80 Pipes, engineered to meet the rigorous demands of modern infrastructure projects. Our commitment lies in delivering products that combine exceptional durability with unwavering reliability, supporting the vital energy and construction sectors across the region. With a focus on stringent quality control and customer-focused service, our team is dedicated to being your preferred partner for robust and dependable piping systems.
The composition of our Grade X80 pipes is carefully balanced, primarily consisting of iron with controlled additions of carbon, manganese, and microalloying elements like niobium and vanadium. This specific metallurgical recipe grants the pipes their impressive mechanical properties. They are defined by a minimum yield strength of 80,000 psi (555 MPa), which provides exceptional resistance to high pressures. This high strength is complemented by good toughness and ductility, ensuring the pipes can withstand significant stress and strain, making them exceptionally suited for challenging environments.
