Our Manufacturing Process

Our forging process involves precision heating and shaping to ensure a superior grain flow, resulting in fittings that offer exceptional structural integrity and resistance to fatigue.

01. Grade Selection

Sourcing premium-quality forged billets in specific grades (F304/F316) for enhanced corrosion resistance.

02. Precision Forging

Hot forging and CNC machining to achieve exact dimensions and high-quality threading (NPT/BSP).

03. Quality Testing

Hydrostatic testing and ultrasonic inspection to ensure 100% leak-proof performance under pressure.
