Multi/Clamp Snap Repair Clamp L=150 mm Stainless Steel AISI 304

  Data Sheet |   Product Range

The Georg Fischer Multi/Clamp Snap L=150 mm is a single-band stainless steel repair clamp built for fast, permanent localised repairs on pressurised industrial piping. The 150 mm band width bridges corrosion pitting, pinholes, frost splits and mechanical surface cracks, and the range covers outside diameters from 15 mm up to 329 mm across 34 clamping ranges. Nominal pressure for water service is PN 16, PN 10 or PN 6 depending on the diameter range selected; the clamp is approved for aboveground installation only.

The body shell is AISI 304 (A2) stainless steel, with AISI 316 available on request. Tightening lugs are heavy-duty ductile cast iron, giving rigid structural backing and uniform bolt torque distribution around the circumference without deforming the pipe wall. All metal parts are produced by automated robotic welding in a dedicated stainless-steel-only environment to exclude ferritic cross-contamination, and every component is fully passivated.

Sealing is provided by a partial-coverage waffle-structure NBR gasket to EN 682, suitable for water and gas distribution networks between -10 degrees Celsius and +70 degrees Celsius. An EPDM gasket to EN 681-1 is available on request for potable water duty between -10 degrees Celsius and +55 degrees Celsius. Working pressures for gas service are to be confirmed with Georg Fischer Waga.

The clamp fits steel, grey cast iron, ductile iron, copper and asbestos cement pipe, as well as plastic pipes such as PVC-U, PE and PP when installed to the stated manufacturer parameters. Select the clamp by the measured outside diameter of the damaged pipe rather than by nominal size, so the gasket works inside its clamping range. Within the Multi/Clamp programme, Snap covers small aboveground repairs, while Midi, Single, Double and Triple address buried lines and larger damage. BigWeld supplies the range as an authorised Georg Fischer distributor.
