Abstract

1420073 Repairing joint leakages in pipes and tubes AVON RUBBER CO Ltd AVON LIPPIATT HOBBS Ltd and BRITISH GAS CORP 16 March 1973 [20 March 1972] 12982/72 Heading F2P In order to effect a joint repair without reducing line pressure, a mould is assembled about a leaking joint and an encapsulant injected thereinto under a controllably externally applied gas pressure, which is greater than the line pressure. Preferably, the mould assembly 7 has a rigid two-part shell (12, Figs. 1 and 2, not shown) surrounding a rubberized canvas or polymeric two-part liner (8). Encapsulant 32 is injected into the liner, through port 26, while gas pressure is applied from source 38 via selfbleed regulator 70. A sight tube 37 may be clamped off during hardening of the encapsulant.
