Leak sealing.

摘要

This invention concerns packing seals for leak sealing clamps suitable for on line leak sealing. The packing seals (24) are suitable for use between a sealing clamp (18) and a flange (16) or pipe being sealed, which fit by compression as well as by bonding to surfaces. The packing seals comprise woven mineral or synthetic fibres impregnated with a thermosetting resin, particularly one that sets at a high temperature.
