As a leading manufacturer and supplier based in Naypyidaw, Naing Steel takes pride in delivering robust solutions for Myanmar’s most demanding industrial projects. Our Carbon Steel WPHY 80 Pipe Fittings are engineered to meet the rigorous challenges of high-pressure and low-temperature environments. We understand that the integrity of your piping systems is paramount, which is why we commit to providing fittings that offer exceptional strength and reliability, ensuring your operations proceed with unwavering confidence and safety.
The composition of these fittings is a careful balance of carbon, manganese, and other micro-alloying elements, which work in concert to achieve their high-strength characteristics. This specific formulation grants the WPHY 80 grade its impressive mechanical properties, including a minimum yield strength of 80 ksi. This high strength is complemented by excellent toughness, making the fittings exceptionally resistant to brittle fracture even under substantial pressure and in colder operating conditions.
