At Solitaire Fittings, we are a trusted supplier and stockholder of ASTM A860 WPHY 46 Alloy Buttweld Fittings that are engineered for strength, durability, and performance. These fittings are widely used in high-pressure oil & gas pipelines, power generation, petrochemical plants, and structural applications.
The term WPHY stands for Wrought Pipe High-Yield, and the number 46 represents a minimum yield strength of 46,000 psi. With superior toughness, corrosion resistance, and pressure-handling capabilities, our ASTM A860 WPHY46 High Yield Buttweld Fittings ensure leak-proof, long-lasting connections in demanding environments.
Whether you need elbows, tees, reducers, caps, or stub ends, our ASTM A860 Grade WPHY 46 Carbon Steel Buttweld Pipe Fittings are manufactured under strict quality control to meet ASTM A860 / ASME SA860 standards.
What is ASTM A860 WPHY 46 Alloy Buttweld Fittings?
ASTM A860 WPHY 46 Pipe Fittings are high-strength carbon steel fittings designed for moderate to high-pressure pipeline applications. These fittings are used to connect, redirect, or terminate pipelines while maintaining the strength of the piping system.
They are available in both seamless and welded construction, depending on customer needs. The seamless type is preferred for critical applications requiring maximum strength, while welded types are used where cost efficiency and larger sizes are required.
The fittings are also compatible with API 5L X46 Pipe Fittings, making them ideal for oil, gas, and petrochemical industries.
