Naing Steel stands as a trusted manufacturer and supplier in Naypyidaw, dedicated to serving Myanmar’s growing industrial landscape with integrity and precision. We take pride in producing robust Carbon Steel WPHY 42 Pipe Fittings, engineered to meet the stringent demands of high-pressure systems. Our commitment extends beyond mere supply; we focus on building lasting partnerships by ensuring reliable performance and consistent quality in every fitting that leaves our facility, supporting the critical infrastructure projects that drive our nation forward.
Crafted for strength and durability, these fittings are composed primarily of carbon steel, with carefully controlled levels of manganese, silicon, and other trace elements to achieve a specific balance. This composition is key to their impressive mechanical properties, which include a minimum yield strength of 42,000 psi. This ensures they can withstand significant internal pressures and mechanical stress without deforming, making them a fundamentally reliable component in any piping system where safety and longevity are non-negotiable priorities.
