✓ Leak-Proof Sealing✓ High-Pressure Rated✓ Precision Machined✓ Full Traceability

Available Types

Weld Neck

For high-pressure/temperature with tapered hub for even stress distribution.

Slip On

Cost-effective for moderate-pressure systems — welded on both sides.

Blind

Seal piping ends and pressure vessel openings — exact thickness specs.

Socket Weld

Small-diameter, high-pressure piping — smooth bore, excellent fatigue resistance.

Lap Joint

Used with stub ends for easy alignment and frequent dismantling.

Threaded

No welding required — for low-pressure and explosive atmosphere applications.
