Ductile Iron Repair Clamps for Water and Gas Service
Hegawa Ductile Iron Repair Clamps have been designed for the permanent repair of ductile iron, cast iron and steel pipes. Even on badly corroded pipes.
Product information
Technical concept
The ‘waffle’ type of rubber with incorporated bridging plates will take care for a quick and permanent leaktight seal. The Hegawa ductile iron repair clamps are constructed of ductile iron half housings giving them a high strength. The clamps will support and seal around the pipe for full length of the body, ensuring that sealing effectiveness is maintained in all circumstances. The inherent strength of the clamps will cater for circumferential pipe shear and also realign pipes.
The clamps can be installed easily, no specialist installation tools are required. Only a torque wrench to confirm the correct bolt torque. The clamps are fully epoxy coated, taking care for a long term corrosion protection. No further protection such as wrapping is required.
Working pressures
The Hegawa Ductile Iron Repair Clamps have been designed for 16 bar working pressure and a test pressure of 24 bars with water applications.
