AI Technical Summary
Existing large-diameter plastic pipes have poor flexibility, small bending radius, are prone to rust, and have a short service life in high-pressure systems. In particular, pipes with TPU + steel wire structure are heavy and prone to rust.
The inner layer of the pipe adopts a fully corrugated structure, with an outer reinforcing layer made of knitted, braided or wound material, and an outer protective layer. The material used is PP, PE, PA, PPA or TPE. The reinforcing layer can be made of PET, PVA, PE or metal wire to improve strength.
It achieves lightweight design, improved flexibility and strength, small bending radius and is not prone to rust, reducing weight by 60% and meeting the requirements of high-voltage systems.
