Universal Double Socket for Multiple Pipe Types
The Double Socket Coupling for Pipelines is our versatile double-socket product. It works with ductile iron, steel, PE, and PVC pipes. This makes it a practical choice for water utilities and maintenance teams. One product fits many pipe materials. It simplifies inventory management and reduces storage costs.
Both sockets have EPDM sealing rings. Insert the pipe ends and tighten the bolts. The coupling accommodates some variation in pipe OD. This is useful when pipes have different coating thicknesses. The bolt locking system provides extra stability for high-pressure or high-vibration applications. The coupling gives you a reliable connection on many different pipe types.
We hold ISO 9001 certification. We inspect every product for appearance, dimensions, and pressure resistance. We record all inspection data. We have a complete after-sales service team. Contact us anytime with questions. We stock standard sizes for 24-hour shipping.
One Product for Many Pipe Materials
A new industrial park used different pipe materials in its water network. The connection points were many. The contractor bought our Double Socket Coupling for Pipelines. One product worked for their ductile iron, steel, and PE pipes. This simplified procurement and reduced inventory waste. The project finished on time and passed the pressure test on the first attempt.
We offer a 10-year warranty. The housing is QT450 ductile iron with epoxy coating. The sealing rings are replaceable for low maintenance cost. We accept third-party inspections.
