Stainless Steel Repair Clamp Georg Fischer Multi/Clamp Midi L=200mm

  Data Sheet |   Product Range

The Georg Fischer Multi/Clamp Midi L=200mm is a single-band repair clamp built entirely from stainless steel, designed for the fast and permanent sealing of localised defects in municipal, utility and industrial pipelines. The 200 mm band length covers pinholes, corrosion pitting, frost splits and mechanical punctures on pressurised and non-pressurised water, wastewater and gas lines. The Midi series uses no cast components, so it is approved for aboveground installation as well as for direct burial.

All metal parts — shells, bridge plate and lugs — are produced in AISI 304 / A2 stainless steel, with AISI 316 available on request. Components are joined by automated robotic welding and fully passivated after fabrication in a dedicated stainless-steel-only environment, which excludes contact corrosion and gives lasting resistance in aggressive soils and corrosive industrial atmospheres.

Sealing is provided by a partial-coverage waffle-pattern NBR gasket to EN 682, rated for -10 degrees to +70 degrees Celsius in water and gas service. EPDM gaskets to EN 681-1 (-10 degrees to +55 degrees Celsius) are available on request for potable water networks with specific elastomer requirements. Nominal pressure reaches PN16, with PN10 applying to the larger clamping ranges inside the 95 mm to 220 mm coverage of this length; gas working pressures are confirmed with Georg Fischer.

The clamp suits ductile iron, grey cast iron, steel, asbestos cement and thermoplastic pipes such as PE, PVC-U and PP, with installation parameters for plastic pipes confirmed by the manufacturer. The wrap-around band and wide clamping tolerance allow a single installer to complete the repair directly on the damaged pipe, keeping downtime and excavation work to a minimum.
