Abstract:
This article investigates the repair process of damaged steel pipes of drinking water transmission lines by polyester resin or putty and a composite patch, as well as the internal pressure capacity of the repaired specimens during burst pressure tests carried out by the experimental method. The main aim is to introduce a completely practical method for repairing the pipelines in out-of-town areas without using electrical or other advanced equipment. In addition, an innovative novelty is employed in the burst pressure tests. Experiments demonstrate that the repaired pipes by the molded polyester putty and a composite patch of ۱۰۰×۱۰۰ mm۲ dimension with ۳ or ۵ layers can approximately sustain the maximum internal pressures up to ۴۴ or ۵۵ bar, respectively; while the repaired pipes by the molded polyester resin and the corresponding composite patch with ۳ or ۵ layers can withstand the maximum pressures up to ۲۸ or ۴۰ bar, respectively. Repairing the pipes by the presented methods helps achieve the main purpose of the present research, with an admissible safety factor.
