Structural diagram of steel wire wrapped skeleton reinforced polyethylene composite pipe: It is mainly composed of five layers: the inner and outer layers are made of thermoplastic plastic, made of HDPE, PERT, etc., and the middle layer is a steel wire reinforcement layer that has been coated with rubber. A layer of bonding resin is added to both sides of the steel wire reinforcement layer to make the reinforcement layer and the inner and outer layers Bonded into one.

Flexible composite high-pressure conveying pipe structure diagram:
It is mainly composed of three layers: the inner thermoplastic pipe is made of thermoplastics such as HDPE, PERT, PA, and PVDF. The middle layer is a reinforced material layer wound at a specific angle. The materials include aramid fiber, polyester fiber, glass fiber, etc. The outer layer is a protective layer, usually HDPE with anti-aging and anti-UV added.
