US 2026/0168608 A1 · ELECTRONIC CURING ASSEMBLY AND RELATED METHOD

Abstract

An electronic curing assembly is for relining a pipe with a first end and second end opposite the first end. The electronic curing assembly includes a bladder tube to be positioned within the pipe and extending from the first end to the second end, an electronic curing device within the bladder tube, and first and second ropes coupled respectively to opposite ends of the electronic curing device, the first rope extending through the bladder tube and to the first end of the pipe. The electronic curing assembly also includes a plug device adjacent to the second end of the pipe and having a housing defining a longitudinal passageway therein, and a retention device carried by the housing and configured to be coupled to a distal end of the bladder tube. The second rope extends through the longitudinal passageway and to the second end of the pipe.
