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.
√ The microcomputer controls and automatically adjusts the coordination of each part of the production line.
√ Long service life with a designed service life of 30 to 50 years.
√ High-speed shot blasting inner and outer wall rust removal equipment
√ High-performance electrostatic spraying equipment with good impact resistance.
√ High-quality PE sheet extrusion equipment with excellent anti-corrosion effect.
√ Fully automatic processing energy-saving inner wall coating equipment.
