Multi/Clamp Flanged Tapping Clamp L=400mm AISI 304

  Data Sheet |   Product Range

The Georg Fischer Multi/Clamp flanged tapping clamp with an installation length of 400 mm is an engineered branching and hot-tapping sleeve designed for creating robust, leak-tight flanged connections on utility and industrial piping systems. Manufactured with a heavy-duty double-band configuration, this saddle ensures uniform radial compression and broad circumferential support across the host pipe, mitigating concentrated mechanical stresses while providing a secure foundation for mounting flanged isolation valves, hydrants, or auxiliary pipeline extensions.

Constructed from high-grade AISI 304 (1.4301) stainless steel, the clamp body, bridge plates, lugs, and bolting components undergo full chemical passivation to deliver superior resistance against atmospheric, underground, and chemical corrosion. Automated robotic welding in a dedicated stainless steel fabrication environment eliminates metallic cross-contamination. The flanged branch incorporates an integrated stainless steel reinforcement ring within the elastomeric sealing assembly to prevent gasket extrusion under internal pressure fluctuations and dynamic network loads.

The sealing system utilizes profiled waffle gaskets available in standard NBR (certified to EN 682 for gas and water applications across a operating temperature range of -10 to +70 degrees Celsius) or EPDM (certified to EN 681-1 for potable water systems from -10 to +55 degrees Celsius). The branch outlet is drilled according to standard EN/DIN PN 10 and PN 16 flange patterns, ensuring direct compatibility with industrial valves and fittings across diverse pipeline infrastructures.

This universal tapping solution accommodates a wide variety of rigid and flexible pipe materials, including ductile iron, grey cast iron, carbon steel, asbestos cement, PEHD, and PVC-U. Its robust dual-segment geometry enables safe installation under operating pipeline pressure, significantly reducing downtime and civil intervention costs during pipeline upgrades, municipal network expansions, and industrial maintenance operations.
