Wide Tolerance Repair Coupling

Description

The Wide Tolerance Repair Coupling is designed for the rapid and secure repair of pipeline leaks, fractures, or section replacements. Its primary feature is the "wide tolerance" capability, allowing it to connect pipes of slightly different outside diameters (OD) or material types without needing to cut or re-align the pipe ends. This makes it the standard choice for emergency leak repairs where speed and reliability are paramount.

Technical Specifications

• Design Type: Wide Tolerance Pipe Coupling (Slip-on)

• Pressure Rating: PN10 / PN16

• Body Material: High-strength Ductile Iron (GGG40/50)

• Sealing: Specialized wide-profile EPDM/NBR rubber gasket (designed to seal uneven or corroded pipe surfaces)

• Coating: Fusion Bonded Epoxy (FBE) for exceptional corrosion resistance

• Hardware: High-tensile steel bolts and nuts with anti-corrosion coating

• Tolerance: Wide OD range capacity (e.g., covering 10mm–20mm tolerance per coupling)

Key Applications

• Emergency Repairs: Rapid sealing of cracks or pinhole leaks in industrial mains.

• Pipe Transitions: Connecting pipes of different materials (e.g., Ductile Iron to Steel or PVC) in emergency scenarios.

• Maintenance & Infrastructure: Essential stock item for site maintenance teams in Mesaieed and Ras Laffan to handle unexpected line breaks.

• Water & Wastewater: Reliable repair of municipal and process water distribution networks.
