Multi/Clamp Triple Repair Clamp AISI 304 L=400mm 267-600 mm

  Data Sheet |   Product Range

The Georg Fischer Multi/Clamp Triple repair clamp with an installation length of 400 mm is an engineered, three-part stainless steel encirclement solution developed for reliable, permanent repairs on large-diameter utility and industrial piping networks. Specifically designed to remediate longitudinal cracks, severe pipe fractures, localized corrosion, and mechanical damage on distribution mains, this heavy-duty triple-band clamp provides full-circle circumferential sealing across broad outer diameter tolerances ranging from 267 mm up to 600 mm. Its robust construction ensures structural integrity and dependable containment under demanding operating conditions in both aboveground and buried pipeline systems.

Manufactured completely from passivated AISI 304 stainless steel with robotic automated welding, the clamp eliminates the risk of contact corrosion and maintains long-term structural resistance against aggressive soil environments and industrial atmospheres. The sealing mechanism incorporates a full-circle waffle-embossed NBR rubber gasket compliant with EN 682 standards, rated for continuous operational temperatures from -10 degrees to +70 degrees Celsius in water and gas conveyance systems. For dedicated potable water applications, EPDM gaskets certified under EN 681-1 are available, covering an operating range from -10 degrees to +55 degrees Celsius. The clamp withstands working pressures up to 10 bar depending on pipeline diameter and medium.

Engineered for maximum versatility, the Multi/Clamp Triple seamlessly adapts to all standard pipe substrates, including ductile iron, cast iron, carbon steel, asbestos cement, PEHD, and PVC-U. The three-section modular design simplifies handling and installation in confined excavations, allowing installers to position the shells around the damaged section without disrupting pipeline continuity or requiring complete system shutdowns. With integrated stainless steel bridge plates and durable threaded studs, the clamp distributes tightening torque evenly across the pipe perimeter, preventing localized point loading and ensuring immediate, leak-tight sealing that drastically minimizes costly downtime.
