Naing Steel stands as a trusted name in Naypyidaw’s industrial landscape, dedicated to providing robust solutions for demanding applications. We take pride in our role as a leading manufacturer and supplier of Alloy Steel WP22 Pipe Fittings, components engineered for exceptional performance under extreme conditions. Our commitment lies in delivering fittings that meet the highest standards of quality and reliability, ensuring the integrity and safety of critical piping systems across various heavy industries in Myanmar and beyond.
The strength of these WP22 fittings comes from a specific chromium-molybdenum-tungsten composition, which gives them a remarkable resistance to high temperatures and corrosive environments. This alloy blend results in outstanding mechanical properties, including high tensile strength and excellent creep resistance, allowing them to maintain structural integrity even when subjected to intense heat and pressure over long periods. This combination ensures they won’t easily deform or fail when the operational demands are at their peak.

You’ll typically find these WP22 fittings hard at work in the most challenging settings, such as power generation plants, petrochemical refineries, and high-temperature processing units. They are essential for constructing and maintaining piping systems that carry superheated steam, hot oils, and other aggressive chemicals. Their ability to withstand thermal stress and oxidation makes them a go-to choice for critical connections in boilers, heat exchangers, and pressure vessels, where failure is simply not an option.
