Pipes used in various industries are usually made of metal. The great importance of pipes in industries as a link between different units is obvious. Due to this level of importance of pipes, which causes all or part of the set to shut down with any kind of problem, it is very important to keep them in the best possible condition for service. One of the many and frequent problems in pipelines is the creation of holes or cracks due to the reduction of their thickness over time. One of the main reasons for reducing the inner thickness is wear, corrosion and mechanical stress on the inner wall of the pipe. In most of the current industries, no coating or protective method is considered for the inner wall of the pipe. In some industries and in recent years, colored coatings such as Epoxy Glass Flake paint are used. Due to reasons such as the lack of proper mechanical strength and improper adhesion to the inner surface, colored coatings are torn off due to abrasion and enter the fluid flow, causing problems in this field. Further, due to the importance of the issue, Farasath Zarfam Company, which has provided composite coatings for various surfaces, conducted research and tests on the application of composite coatings inside pipes. According to the tests, the inner coating of the pipes has greatly influenced the life of the pipes and has prevented corrosion and reducing the thickness of the pipes. Also, this method has been used in pipe connections so that pipe flanges are completely covered with composite coating.
For the composite coating inside the pipe, Farasath Zarfam Company first cleans the pipe from any internal dust and rust and applies the designed composite layer, which is designed based on the working conditions of the pipe in practice, on the inner surface of the pipe. The design will be done based on conditions such as temperature, pressure and acidity. Next, the composite will be covered with special gel coat from the Farasath Zarfam company and it will be ready to be installed on the site. By using the internal coating of the composite from Farasath Zarfam company, the above-mentioned factors such as wear and corrosion will reach their lowest level, which obviously increases the service life of the pipe, and it will save the complex from performing maintenance operations that cost a lot. Farasath Zarfam Company has a very successful project in this field in its portfolio. The seawater pipes, which are very prone to leakage, corrosion and wear, were prepared using the pipe internal coating method before installation at the Aria Sasol terminal and were transported to the site for installation.
Farasath Zarfam Company is ready to apply the necessary composite coatings based on the customer’s needs inside the pipe before installing all types of process and non-process pipes so that the least possible damage occurs to the pipeline during servicing.
