AI Technical Summary
Existing steel-reinforced polyethylene threaded corrugated pipes are prone to deformation, insufficient pressure resistance, and corrosion when buried underground, resulting in short service life and high maintenance costs.
A connecting groove is provided on the lower side of the corrugated block of the corrugated pipe, and a protrusion is provided on the inner side of the connecting groove as an interlayer between the steel strip and the polyethylene layer. The protrusion and the reinforcing rod are used to disperse the pressure and enhance the support of the steel strip. A corrosion-resistant layer is added on the inner side of the polyethylene layer to improve the corrosion resistance.
It significantly improves the ring stiffness and compressive strength of the bellows, extends its service life, and reduces maintenance costs.
