High - Speed Composite Pipe Production Line Automotive Fuel Tube Making
Multilayer PA Nylon Oil Tube Extruder Machine
Automotive Fuel Tube Production Line
PA multilayer composite pipe of automotive fuel system is internationally widely used in car fuel oil system which features a kind of portable, high performance and environmental protection line products.
PA automotive fuel tubes have different layer structure, like two layer, 3 layer and 5 layer with oxygen barrier. its outside diameter has 6 mm, 8 mm, 10 mm and other different specifications.
PA multilayer oxygen barrier pipe can effectively reduce the automobile emission pollution to the environment, and meet the higher environmental requirements. At the same time multilayer composite pipe possesses excellent resistance to penetration performance, can satisfy the EU-III standards.
.
Multilayer Pipe Structure:
- Inner layer: PA 12
- Inner adhesive layer
- EVOH oxygen barrier layer
- Outer adhesive layer
- Outer layer: PA 12
