3LPE Coating Pipe Production Line with Internal Liquid Painting and External 3LPE Coating for SA2.5 Clean Level

External 3PE anti corrosive internal epoxy coating is an efficient anti-corrosive method for steel pipes.

Epoxy powder mainly plays an anti-corrosion role, adhesives enhance the bonding between the layers, and polyethylene provides good mechanical protection and environmental resistance. Internal epoxy coating spraying has strong anti-corrosion adhesion and good chemical corrosion resistance, which can effectively prevent the inside of the steel pipe from being corroded by the conveying medium (such as oil, gas, water, etc.). This anti-corrosion method is widely used in the fields of oil and natural gas pipelines, water supply and drainage pipelines, etc., and can greatly extend the service life of steel pipes.

Production line parameters:

(1) Steel pipe coverage range: 114mm-4200mm
(2) Processing capacity: ≤250m²/h
(3) Cleaning level: Sa2.5
(4) Materials used: epoxy powder, adhesive, polyethylene, epoxy coating (single component, two-component)
(5) Main equipment: steel pipe external rust removal equipment, steel pipe internal rust removal equipment, medium frequency heating equipment, epoxy powder spraying equipment, AD adhesive extrusion equipment, PE polyethylene extrusion equipment, cooling equipment, PE groove equipment, high-pressure airless spraying machine, curing furnace heating and drying equipment, spray marking equipment, catalytic combustion environmental protection equipment, etc.
