Liquid Epoxy (LE) Coated Line Pipe
Liquid epoxy (LE) coated line pipe is a pipe with excellent anti-corrosion properties. The inner wall is coated with liquid epoxy coating to form an anti-corrosion layer, which can effectively prevent the transportation medium from corroding the inner wall of the steel pipe.
Liquid epoxy coating is also called water-based epoxy coating. It has the characteristics of saving resources, low pollution, and good anti-corrosion effect. It uses water instead of organic solvents and has excellent environmental performance.
Liquid Epoxy Coatings This is suitable for steel pipes for fluid transportation with low pressure, such as oil, steam, water, sewage, air, heating steam and flammable fluids. It is also suitable for steel pipes for other fluid transportation pipelines with similar requirements.
During the construction process, it is necessary to strictly follow the construction procedures, including preparation work, nozzle cleaning, nozzle preheating, nozzle surface treatment, temperature measurement epoxy, paint application, inspection and acceptance, etc., to ensure that the construction quality meets the standards Require.
Specifications and standards for liquid epoxy coatings are AWWA C210, SHELL DEP 31.40.30.35, EN 10301, ISO 15741, API RP 5L2
