Alloy Steel WP1 Pipe Fittings are low-alloy steel components made up of a mix of carbon, manganese, phosphorus, sulfur, silicon, chromium, and molybdenum. Typically, their chemical makeup includes Carbon (≤0.05–0.15%), Manganese (0.3–0.8%), Silicon (0.1–0.5%), Phosphorus and Sulfur (≤0.025%), Chromium (0.4–0.7%), and Molybdenum (0.45–0.65%). These fittings are known for their impressive mechanical properties, boasting a minimum tensile strength of 380 MPa, a yield strength of 205 MPa, and an elongation of 30%. With great weldability, high-temperature strength, and resistance to corrosion, Alloy Steel WP1 fittings are a go-to choice for pressure piping systems and environments that experience high temperatures.
These fittings find extensive use in industries where strength, toughness, and the ability to withstand heat and pressure are crucial. They’re perfect for power plants, oil and gas refineries, petrochemical facilities, and thermal plants. Common applications include high-pressure steam lines, boiler equipment, heat exchangers, and chemical processing systems. Their resistance to oxidation and creep makes them ideal for high-temperature service applications. Plus, WP1 fittings provide secure, leak-proof connections, which are vital for transporting fluids and gases under extreme conditions, making them a top choice for critical infrastructure projects.
