What is Flange Repair Clamps ?
One of the fundamental aspects of a damaged/deteriorated pipe that dictates the type of repair component to be applied is the external pipe surface condition. If the external surface is damaged to the extent that an elastomeric seal cannot provide sufficient sealing forces in the immediate vicinity of the damage, or in the relatively unaffected areas adjacent to the major damage (these areas being used to effect the sealing of ‘stand’-off repair clamps), the external pipe surface may need to be re-instated using some form of filler material. Products comprising of composite wrap and rebuilding materials have been shown to accommodate such areas of extensive damage and have applications for a whole range of defects, including corrosion, non-propagating cracks, dents or gouges in both axial and circumferential orientation, and girth weld associated anomalies.
Why Flange Repair Clamps are pre-fabricated?
Flange Repair clamps WA-FRC units are a permanent repair clamps for leaking flange gasket. The unit is installed without taking the line out of service.
Operation line pressures up to 2500 psi, seals may be Viton, NBR, EDPM.
No special flange surface preparation is required, no costly shutdowns for installation.
Flange repair clamps can be installed by company maintenance personnel. There is no altering of existing flanges, other than cleaning the flange.
On scheduled shutdown maintenance the flange repair clamp can be removed and the gasket replaced. The unit may put back in service or held in stores for future repair.
Injection sockets are utilized to fully seal the compartment. In case of a small gap between the line flanges, gaskets can be installed for temporarily sealing prior too and during injection.
