What is Epoxy coating internal?

Internal epoxy coating is a common anti-corrosion treatment, it is usually used in pipelines, water tanks and other closed occasions. It provides a layer of "protective film" for the interior of pipelines, water tanks, etc., so that it has a certain degree of corrosion resistance. The following is its processing technology, application fields and characteristics and advantages.

Processing technology
Preconditioning: First of all, the pipe that needs to be sprayed is preheated in the tube, and then the inside of the pipe is sandblasted or shot blasting to remove the oxidation layer, rust and other pollutants inside the pipe. Then the tube is purged, and the rust removal test is carried out. After the test is completed, the tube end is treated with stickers to prevent dust from entering.
Spraying: Use the spray gun to evenly spray the epoxy coating on the inner wall of the steel pipe, where the thickness of the coating should meet the standard. After spraying, the wet film test is carried out, and the dry film test is carried out after the coating is dry, and the coating is repaired.
Warehousing: The finished product of the sprayed steel pipe is tested, marked if there is no problem, and the pipe end is protected, and it can be stored after completion.

Application field
The application field of internal epoxy coating is very wide, mainly used in drinking water pipelines, oil and gas pipelines, chemical pipelines, sewage treatment pipelines and so on.

Features and advantages
Excellent anti-corrosion performance: can block the erosion of water and other corrosive substances, to prevent the aging of the pipeline rust.
Environmental hygiene: The epoxy coating that meets the standard can be used to transport drinking water, which can ensure the safety of water quality and avoid pollution.
It has certain wear resistance: it can resist the erosion of fluid substances and extend the service life of the steel pipe.

In summary
The internal epoxy coating is a reliable and durable anti-corrosion measure, which not only protects against corrosion, but also ensures the purity of the medium (such as water), which is widely used in the transportation of drinking water and the transportation of corrosive substances.
