Process Of Lining Pipes

The process of lining pipes with rubber, while not especially difficult, is crucial to the protection of the pipes from corrosive chemicals. Here is a brief breakdown of how the process goes. 1. The pipes must first be inspected so that it can be verified they are physically capable of handling the lining process. The workers must check to see if the internal area of the pipes is accessible and that the contours are conducive to smooth lining with no layering defects. 2. After it has been verified the piping is physically capable of being lined with rubber, the surface must be prepared. This generally consists of removing any excess rust or mineral scales with a wire brush. In extreme cases or larger jobs, a sandblaster may be used. 3. Once the surface area has been cleaned, the rubber lining will be applied. This is a very important aspect of any underground project as it will prevent having to dig up the pipes and replace them when they are being used with corrosive chemicals. 4. After the liquid rubber solution has been applied, the rubber must be properly cured. This is done at a very high temperature using either steam or hot water. In cases where extremely high temperatures are not viable, there are additives and fillers which can be used to hasten the curing process. 5. Once the rubber lined pipe has been cured, it will need to be inspected to ensure there are no pinholes or other defects that can wreak havoc when the pipes are in use. The lining must be completely smooth and perfect on the surface to be used in industrial applications. 6. The final step of the process is to pressure test the pipe using high-pressure water or other testing solutions. Once the pipe has been tested, it will be put into use in an industrial situation.
