Liam Steel is a well-respected manufacturer and supplier located in Manila, Philippines, specializing in top-notch Alloy Steel WP22 Pipe Fittings. These fittings are crafted for high-temperature and high-pressure settings, boasting remarkable strength, durability, and resistance to corrosion. Liam Steel is committed to precision engineering, following international standards, and conducting rigorous quality tests to ensure their products perform reliably in critical applications. With a strong emphasis on innovation and customer satisfaction, the company caters to various industries, including power generation, petrochemical, oil and gas, and chemical processing, providing robust and efficient piping solutions tailored to meet demanding operational requirements.
Alloy Steel WP22 Pipe Fittings primarily consist of chromium (2.0–2.5%) and molybdenum (0.87–1.13%), along with smaller quantities of carbon, manganese, silicon, and phosphorus to boost mechanical strength and oxidation resistance. These fittings deliver a tensile strength of approximately 415–585 MPa and a yield strength of around 205 MPa, along with excellent creep and stress rupture characteristics. They maintain their structural integrity even under high thermal and pressure conditions, making them perfect for long-term use in elevated temperature environments.
