Steel Pipe Internal Fbe External 3lpe Anti-Corrosion Coating Machinery for oil natural gas
Product Description
Structure
External 3PE anti-corrosion:
It adopts a three-layer composite structure, with the bottom layer being epoxy powder, which mainly plays an anti-corrosion role. The middle layer is an adhesive, which is used to enhance the bonding force between each layer. The outer layer is polyethylene, which can provide good mechanical protection and environmental resistance.
Internal anti-corrosion:
By spraying epoxy paint, taking advantage of its strong adhesion and excellent chemical corrosion resistance, it prevents the oil, gas, water and other media transported inside the steel pipe from corroding.
Application
The external 3PE anti-corrosion combines chemical anti-corrosion with mechanical protection, and the synergistic effect of each layer enhances the anti-corrosion effect. The internal epoxy coating spraying is specifically designed to solve the corrosion problem of the conveyed medium. This anti-corrosion method is highly efficient and durable, and can significantly extend the service life of steel pipes.
It is widely applied in fields such as oil transportation pipelines, natural gas transportation pipelines, water supply and drainage pipelines, etc., providing a guarantee for the long-term safe use of various pipelines.
