Epoxy coal tar pitch provides good corrosion protection for buried pipelines

Thread Content

We know that at present, our country has many excellent and advanced methods and materials for buried pipelines, which can be used for the construction of large-scale projects. However, for some enterprises, the volume involved in pipeline overhauls and upgrades is small, and the use of more advanced materials and methods is restricted by factors such as quantity and cost. So adopting some traditional methods is also a good choice. The image above shows fiberglass reinforced plastic made from polyamide epoxy coal tar pitch, which was used by a company during pipeline renewal. The basic manufacturing process is as follows: two coats of primer for floor treatment (as part of the complete set) – fiberglass reinforced with two layers of fabric and five layers of resin, with a thickness of over 0.5 millimeters. It works well when used, and can last for over 15 years. However, material selection and construction quality must be under control. Only in this way can a good construction project be created that can stand the test of time. Through this incident, what I want to say is that the idea that traditional methods don’t work well is somewhat misplaced.
