A gasket for noting an annular space between two pipes comprises an annular elastomeric member ( ) having a concave formation on at least one longitudinal end face, compression members ( ) adjacent the longitudinal end faces and connected via a plurality of securing means ( ) adapted to urge the compression members ( ) together, the compression member or members ( ) adjacent a concave formation on the elastomeric member ( ) including a corresponding convex formation. The elastomeric member ( ) can also include a concave formation on at least one radial face ( ), in which the gasket can further include at least one (preferably elastomeric) filler member in that concave formation, on the radial ( ).

Gasket

Two embodiments of insulated pipework system are described. The first comprises an outer sleeve, an inner flow pipe and insulating material within the space therebetween and is characterised by the use of a longitudinally compressed elastomeric member in the space between the inner and outer pipes as the primary means for transferring longitudinal forces between the inner and outer pipes. The second comprises an outer sleeve pipe, an inner flow pipe, an insulating material within the space therebetween, other than hollow alumina-silicate microspheres, wherein a longitudinally compressed elastomeric member is provided at intervals in the space between the inner and outer pipes. Compression of the elastomeric member is preferably by way of rigid plates on either side thereof which compress an the elastomeric member. For example, bolts can be passed through bores in the plates and elastomeric member and tightened thereby to compress the said member. The elastomeric member is preferably in annular form and hence extends around the entire annular space between the two pipes.
