The main constituents of Alloy Steel WP22 Pipe Fittings are molybdenum (~0.87–1.13%) and chromium (~2.0–2.5%), with trace amounts of carbon (≤0.15%), manganese, phosphorus, and sulphur. These components help provide exceptional strength and oxidation and heat resistance. To attain the best mechanical qualities, the fittings undergo normalisation and tempering heat treatments. WP22 fittings normally have an elongation of about 20%, a yield strength of 205 MPa, and a tensile strength of 415–585 MPa. Because of these qualities, they are perfect for high-temperature service settings that call for stability, robustness, and resistance to thermal fatigue and creep.

Yes, custom sizes for Alloy Steel WP22 Pipe Fittings are available at Harry Fittings. We offer tailored solutions to meet your specific requirements, ensuring optimal performance for your projects. For more information, please contact us at sales@harryfittings.us.
High-temperature and high-pressure piping systems, particularly those found in refineries, boilers, petrochemical facilities, and thermal power plants, frequently use alloy steel WP22 pipe fittings. They are perfect for applications where structural integrity under heat stress is essential, such as pressure vessels, heat exchangers, superheaters, and steam pipelines. Excellent resistance to oxidation, scaling, and creep deformation at high temperatures is guaranteed by the chromium-molybdenum composition of WP22. These fittings are crucial for energy production and chemical processing applications needing long-term performance and safety under challenging circumstances because they offer strong, leak-proof connections in systems transporting superheated steam and high-temperature fluids.
