Pipe Clamps, Clamp Bases

Attention: open in a new window.

Due to the additional effects of temperature, the pipe clamps and clamp bases are the most vulnerable components of the support chains in heat conducting piping.

At the same time, the insulation surrounding them makes regular inspection very difficult. As these components are therefore considered to be critically important, particular attention must be paid to their design and quality.

LISEGA pipe clamps and clamp bases herald a new generation of pipe surrounds and their key feature is exacting stress-related design:

coverage of a range of up to OD 48'' and 169 kip with standard types
designed for 200,000 hours fatigue life and temperatures up to 1200°F
compatibility of connections and load groups within the LISEGA modular system
verification tests by independent authorities


		U-bolts type 40 Type 40 serves mainly to secure piping of max. 175°F [80°C] temp. to secondary steel structure.				Weld-on lug type 41 This type is used principally as a pipe connection for piping under 175°F [80°C] on horizontal pipes or elbows.

		Horizontal clamp type 42 This clamp can be used as a construction component or hanger clamp in cold piping systems. For larger pipe diameters the load range is limited.				Horizontal clamp type 43 This hanger clamp corresponds to the traditional shape made from flat steel. Its use is limited to an economical range up to a unit weight of approx. 55 lbs [25kg].

		Horizontal clamp type 44 A rigid yoke takes on the load from a pipesurrounding U-bolt with an inlay plate. From certain diameters, temperatures or load ranges, a flat steel strap is used instead of a U-bolt.				Connecting plates type 77 Twice the specified load is possible by coupling two pipe clamps with Type 77.

		Riser clamp type 45 With the riser clamp type 45, the lower range suited to this design is covered. Connection to the vertical piping is made via the shear lugs welded to the pipe. The design and application of the lugs is the responsibility of the piping manufacturer.				Riser clamp type 46/48 The design of this riser clamp exploits the box shape as the best precondition for the economical use of material. The individual parts are bolted together without weldings via socket connections.

		Clamp bases type 49 Clamp bases are generally used as slide bearings (loose supports) for horizontally arranged piping systems.				Two fold or manifold guidings Two-fold or Manifold guidings using standard clamp bases can be supplied if required.

		Lift-off restraint for clamp bases The clamp bases can if required be fitted with lift-off restraints.				PTFE or graphit bearings The slide bearings of all clamp bases can be supplied as sliding surfaces for a PTFE or graphite bearing.
