The "one-step" production line integrates the continuous process of anti-corrosion coating application, insulation material filling and outer protective layer extrusion, improving efficiency, reducing costs and ensuring quality. Mainly produce polyurethane insulation pipes, ensuring that each layer is closely combined, with a high degree of automation and reducing manual operation. The product is used in fields such as heating and oil transportation. Due to the continuous completion of multiple processes on the same production line, it features high production efficiency, great application potential and good return on investment.

Main Equipment:

-- Steel pipe derusting equipment
-- PE extrusion machine
-- Forming molds
-- Deviation-correcting devices
-- Cooling equipment
-- Cutting equipment
-- Pipe transfer systems
-- Spray marking system
