Georg Fischer Multi/Clamp Double Pipe Repair Clamp L=200mm

  Data Sheet |   Product Range

The Georg Fischer Multi/Clamp Double stainless steel repair clamp with an effective length of 200 mm provides a robust, permanent sealing solution for leaking, cracked, or damaged pipelines. Featuring a two-part double-band construction, this repair coupling offers an extended tolerance range per nominal diameter, allowing secure sealing on pipes with irregular outer surfaces, slight ovality, or varying wall thicknesses. Manufactured by Georg Fischer in a dedicated stainless steel facility to eliminate contact corrosion, every Multi/Clamp unit undergoes automated robotic welding and full acid passivation to ensure exceptional corrosion resistance in underground and aboveground utility or industrial networks.

The clamp housing and bolts are fabricated from high-grade AISI 304 stainless steel (with AISI 316 available on request), ensuring dependable mechanical strength under continuous working pressures up to PN 16 or PN 10 depending on the diameter range. The sealing system consists of a full-circle waffle-patterned NBR elastomer gasket conforming to EN 682, suitable for water, wastewater, and gas distribution networks within an operating temperature range of -10 degrees Celsius to +70 degrees Celsius. For dedicated potable water applications, EPDM gaskets certified to EN 681-1 (-10 degrees Celsius to +55 degrees Celsius) are also available.

Compatible with virtually all rigid and flexible pipe materials—including ductile iron, grey cast iron, carbon steel, asbestos cement, and thermoplastics such as PEHD, PVC-U, and PP-H—the Multi/Clamp Double 200 mm ensures quick installation under pressure without requiring complete pipeline shutdown. As an authorised Georg Fischer distributor, BigWeld supplies the complete Multi/Clamp range with full technical documentation, verified factory certification, and rapid dispatch across European industrial sites.
