PIPE ADAPTER
Technical Specifications – Pipe Adapters
-
Application: Heavy-duty adapters for connecting pipes of different diameters.
-
Sealing System: One-piece conical EPDM gasket providing secure, leak-resistant sealing.
-
Performance: Uniform tightening increases sealing pressure, ensuring reliable operation under high-pressure conditions.
Dimensional Ranges and Operating Pressure
Large-diameter couplings cover OD 415–935 mm, with a 400 mm body width, 25 mm tolerance range, PN16 working pressure, and M16 threaded fasteners.
The dimensions shown are for reference only and do not represent the full range. For complete technical specifications, please contact the supplier.
Materials of Construction and Structural Components
The casing and flanges are made of ST 37, ST 44, or ST 52 structural steel with epoxy coating, using galvanized grade 8.8 bolts for high strength and corrosion resistance.
Sealing System and Leak-Proof Performance
The sealing system uses a one-piece EPDM sleeve, providing leak-proof performance, compensating tolerances up to 25 mm, and supporting continuous operation at 16 bar.
HDPE PIPES
Technical Specifications – HDPE Gripper Clamp
-
Application: Repair and connection of HDPE/PE100 pipes with anti-pullout mechanical grip.
