Epoxy pipe repair is an alternative to using hot work and welding to repair a pipe. In industries, epoxy is used to repair equipment and machinery due to its accessibility and cold curing properties. Here are three tips on why epoxy pipe repairs are preferable to alternative repair methods. 1. Corrosion Chemicals, water and water constituents such as salt cause corrosion. Over time, these factors create a corrosive environment for metal piping. They cause rust, wear, chipping and leaks. Metal-to-metal welding may not resolve corrosion, as the new metal will also corrode due to the environment. One way to prevent damage is by using an epoxy pipe repair method. An epoxy coating will create a barrier between the substrate and any corrosive variables that may affect the pipes whether inside or outside. Epoxy coatings cure into a solid material that has a long pot life which, in turn, will protect equipment for a long period of time. epoxy Corroded interior of a pipeline 2. Erosion Abrasive materials cause erosion. For example, stones and metals wear down the inside surface of pipes and shafts. Eventually, the pipe will have through-wall holes and other defects that will impair operations. An erosion resistant epoxy coating can protect the inside of a pipe from abrasive materials and resist any impact and wear over time. Instead of replacing or welding the pipe, which is time consuming and a temporary fix, repairing a pipe with epoxy will allow for a quick return to service without stopping operations. Equally important, the hardened epoxy coating will not suffer the same damage as a welded solution as the metal will suffer the same as the pre-existing substrate. epoxy eroded interior of a tube 3. Efficiency Finally, erosion and corrosion damage will affect the efficiency of the pipelines. Any notches or the like will make it more difficult for items being carried, especially liquids, to pass through. However, a hydrophobic coating will allow liquids to flow down the pipe. Additionally, the hydrophobic coating provides excellent corrosion resistance at low cost, making it an excellent epoxy repair method. On the other hand, a new pipe will arrive without imperfections, but it will not have hydrophobic properties that will perform less efficiently than a coating developed for the transport of liquids. In general, epoxy coatings for pipe repair offer long-lasting solutions where welding and other repair methods cannot, as they are susceptible to the same industrial problems that cause initial problems. Epoxy Pipe Repair Case Study In mining operations, solid and liquid slurries are transported through pipelines. These sludges are highly corrosive since they are made of chemicals and solvents. In addition, they are highly erosive since they include heavy and rough substances. Typically, mining facilities will encase equipment and piping to prevent damage. A phosphate plant in Africa purchased new discharge pipes; however, they required an erosion and corrosion resistant coating to protect it from acid slurry. The new pipes were sandblasted and coated with Belzona 1321 (Ceramic S-Metal), an epoxy pipe repair product, as it can resist erosion and corrosion. The phosphate plant created pipelines that would have the long life they needed. epoxy Pipe before repair coating with epoxy epoxy Pipe after repair coating with epoxy Therefore, if you still do not use epoxy materials and you are convinced after reading this post, contact us at rodator@rodator.com
