Seeking expert advice on fiberglass reinforced plastic pipes regarding pipe repair issues?
Thread Content
The fiberglass-reinforced plastic pipes in our plant’s dilute acid system have been experiencing leaks ever since they were put into operation; these leaks generally occur at the joints between the pipes, and they are likely caused by construction issues. Now, only patching can be used to solve it. I have a few questions I would like to ask the experts. How are fiberglass-reinforced plastic pipes typically repaired? For repairing fiberglass-reinforced plastic pipes, we use resin (96%) + curing agent (2-4%), or sometimes an additional curing accelerator, but the results are not good – the repairs do not hold up over time. Also, how much time is required for the complete curing of “resin + curing agent”? Because we can only carry out repairs online at the moment, or suspend operations temporarily to make the repairs. Please share your experiences, experts. Thank you.
Please be willing to incur some costs so that our company can resolve the issue for you. There are many reasons for this: construction issues, structural problems, and material selection issues. If you need assistance, please call us.
I suggest hiring a professional manufacturer to carry out this repair. Although manufacturing fiberglass products doesn’t seem particularly difficult, there are many factors that can affect their quality, such as temperature, humidity, the proportions of the ingredients used, the skill level of the workers, and the operating conditions of the equipment.
If a fiberglass reinforced plastic pipe leaks, it is incorrect to simply repair it by covering the outside area. Fiberglass reinforced plastic pipes are divided into a lining layer and a structural layer during manufacturing; the lining layer primarily provides corrosion and leakage resistance, while the structural layer provides strength. Therefore, when installing pipes, for pipes with a large diameter, it is best to seal the inside of the pipe. For smaller pipes, the pipe ends need to be polished until they reach the lining layer; if this is not possible, the lining resin must be used for sealing first, before the pipes can be joined together. To repair such pipes, they must be disconnected, and the corroded sections of the pipe need to be removed.
It is recommended to switch to steel-reinforced plastic composite pipes. These pipes have a unified wall structure, eliminating issues such as delamination; they offer excellent performance and serve as a replacement for traditional fiberglass-reinforced plastic and plastic-lined pipes
