ABSTRACT:
A separable, lightweight and inflatable pipe joint sealing and testing apparatus for large diameter pipes having a multi-membered arched channel support structure having a circular configuration, and having three parallelly disposed channel members extending outward therefrom, and having outer channel members and a centrally disposed testing channel member. A unitary inner sleeve sealing member coextensive with the channel members is provided for covering the channel support structure. The pipe joint sealing and testing apparatus further has a pair of inflatable annular sealing ring members for placement in the outer channel members, a compressed air source means in communication with the pair of inflatable sealing rings, and a compressed fluid ingress and egress structure through the port of the centrally disposed channel member. The apparatus further has a removable test panel mountable to the channel support structure, which has control mechanisms and air pressure and fluid pressure indicators mounted thereto and which are in communication with the compressed air source means and the compressed fluid ingress and egress structure. Additionally, adjustable wheel assemblies are mounted to the interior of the support structure for centering the apparatus about a pipeline joint and for moving the apparatus in a pipeline. An outer sleeve with a chemical dispensing assembly is further provided to chemically seal and pack pipe joint leaks.
