3LPE/PP/FBE External Coating Machine Epoxy Powder Coating Production Line

The outer anti-corrosion layer of 3PE steel pipe in this production line is a kind of anti-corrosion structure composed of the bottom epoxy powder, the middle layer adhesive and the outer layer polyethylene composite. It has the advantages of high mechanical strength, excellent electrical insulation performance, high mechanization degree of production line, relatively stable process parameters, no pollution to the environment, etc., to ensure the corrosion resistance of the steel pipe during use. This technology has a wide range of applications in the field of pipeline transportation, which can extend the service life of steel pipes and improve the reliability of pipeline systems.

Automatic steel pipe bends fittings 3LPE coating line

is an advanced solution to apply 3LPE/FBE external coating on steel pipe bends, which are widely used in pipeline systems for the transmission of oil, gas, water and other fluids.They have highly resistance to corrosive from chemicals, moisture, harmful environment etc.

Russian SPV Steel pipe company, originally a steel pipe only business, because the Russian market has a large number of anti-corrosion steel pipe demand, they decided to invest in the construction of a production line for pipeline anti-corrosion. After signing the order with Walstad last year, Walstad prepared its production equipment for shipment according to the schedule requirements.

Service:The seller would send technician to the buyer's factory to test the new machine and train people of the buyer. The buyer should pay for round-trip transportation expense, food, accommodation, insurance locally and related salary.

The traditional 3pe anti-corrosion production line generally has three forms, whether it is the double-layer epoxy powder Ownchart operation method, or the manual heating installation method of polyethylene heat shrink sleeve, there are obvious defects to a certain extent. How to avoid all the above defects has become the direction of technological development, and it is the purpose of achieving high-quality anticorrosion in the real sense.
