Nickel Alloy Forged Socket Weld Fittings

Socket weld forged fittings are pipe fittings where the pipe is inserted into the socket and then connected by fillet welding. Featuring high connection strength, few leakage points, and convenient installation, they are widely used in high-pressure piping systems, chemical plants, power stations, shipbuilding, and military industries. The nickel alloy socket weld forged fittings supplied by Hefei Tailan Metal Co., Ltd. are manufactured from high-quality nickel-based alloy forgings through multiple precision processes including die forging/open die forging, solution heat treatment, machining, drilling, and pickling/passivation. Featuring dense structure, precise socket depth, uniform wall thickness, and excellent corrosion resistance, they are specifically designed for small diameter pipe connections under high pressure, high temperature, and severe corrosion conditions.

Strict Non-Destructive Testing

Every nickel alloy socket weld fitting undergoes rigorous NDT inspection:

1. Penetrant Testing (PT) : Detecting surface-opening defects, conforming to ASTM E165 standard
2. Ultrasonic Testing (UT) : Internal defect inspection for critical service fittings
3. Hardness Testing: Verifying heat treatment effectiveness and mechanical property uniformity
