We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Offered in a diverse array of types—**elbows, tees, reducers, caps, crosses, and stub ends**—WP11 fittings are crafted to accommodate **seamless or welded pipe systems** and are usually supplied in a **normalized and tempered** state. They provide a **minimum tensile strength of 415–585 MPa**, depending on the class and wall thickness.
Alloy Steel WP11 pipe fittings are extensively applied in high-temperature and high-pressure resistant industries. Typical uses are in power plants, boilers, and steam lines, where the fittings are required to ensure pressure and temperature integrity. They are also applied in refineries, petrochemical plants, and chemical processing facilities, where resistance to heat and stress is paramount.WP11 fittings are suited for high-temperature water, gas, and steam-carrying systems. They have sufficient corrosion resistance and mechanical strength to make them ideal for critical services such as reheater and super heater lines for long-time performance and reliability under harsh environments.
