What is ASTM A860 WPHY 70 Alloy Buttweld Fittings?
ASTM A860 WPHY 52 Alloy Buttweld Fittings are pipe fittings made from high-strength carbon steel with a minimum yield strength of 52,000 PSI (52 ksi). "WPHY" stands for Wrought Pipe High-Yield, which means these fittings are designed to handle high-pressure pipelines carrying gas, oil, water, and petrochemical substances.
These fittings are manufactured according to ASTM A860 and ASME SA860 specifications, ensuring they meet strict requirements for mechanical and chemical properties. They are commonly used in API 5L X52 pipeline systems in India and across the globe.
Some of the most common fittings in this grade include:
- WPHY 52 Carbon Steel Elbow (45°, 90°, 180°)
- A860 WPHY 52 Pipe Fittings (Reducers, Tees, Caps, Cross)
- WPHY Gr 52 Long Radius Bend
- ASTM A860 WPHY 52 Welded Pipe Fittings
- MSS SP75 WPHY 52 Fittings
