Luke Steel is a world-known producer and supplier of high-quality Alloy Steel WP22 Pipe Fittings, with its base in Houston, USA. Celebrated for its adherence to quality, innovation, and dependability, Luke Steel supplies top-quality piping solutions to satisfy the needs of high-performance industries. WP22 fittings are engineered according to international standards and constructed to withstand high pressures and temperatures, ideal for demanding applications. Supported by technical know-how, timely delivery, and competitive pricing, Luke Steel is a value-added partner for engineers and project managers in the oil & gas, power, petrochemical, and industrial infrastructure industries.
WP22 Pipe Fittings are made with a main composition of Chromium (2.00–2.50%) and Molybdenum (0.87–1.13%), with a carbon steel base. The composition increases their heat resistance, corrosion resistance, and wear resistance. WP22 fittings are mechanically strong, with high tensile strength (415–585 MPa), high yield strength (≥205 MPa), and high hardness, making them appropriate for demanding usage. WP22 fittings are suitable for good weldability and formability, with easy installation and long-term durability under changing operational pressures and temperatures.

Alloy Steel WP22 Pipe Fittings are made up mainly of 2.00–2.50% Chromium and 0.87–1.13% Molybdenum, with a base of carbon steel. The composition of this alloy, which adds strength to resistance against heat, corrosion, and mechanical wear. These fittings have impressive mechanical characteristics, such as tensile strength from 415–585 MPa and a minimum yield strength of 205 MPa. The material is designed to be highly hardness, toughness, and thermal stability. WP22 also has good weldability and formability and is, therefore, a tough yet flexible option for high-temperature and high-pressure use in harsh environments.
