Socket Pipe Fittings
- High-pressure rating: Designed for Class 3000 / 6000 service in demanding piping systems.
- Size and schedule: Non-standard diameters and wall thicknesses manufactured according to drawings or project specs.
- Leak-tight welding: Socket-weld ends provide robust, permanent joints with minimal risk of leakage.
- Corrosion resistance: For hostile or corrosive conditions, stainless steel and carbon steel grades are available.
- Versatile range: Includes elbows, tees, unions, couplings, and caps to cover most pipeline layouts.
