Polyester fiber reinforced adhesive flexible composite pipe (DN40-250)
Polyester fiber reinforced adhesive flexible composite pipes are designed to address the problems of severe corrosion, short service life, high maintenance costs, and low pressure resistance of traditional non-metallic pipes in gathering and transportation pipelines.
The bonded composite process improves the overall mechanical performance of the composite pipe, with a higher pressure resistance level and stronger resistance to external pressure deformation compared to traditional non bonded flexible composite pipes, and a larger manufacturing diameter; Better impact resistance, tensile resistance, and gas permeability resistance; The integral pipe wall structure can be welded by non-metallic sleeve electric heating fusion. This non-metallic reinforced joint connection technology completely solves the problem of traditional flexible pipe metal joints being prone to corrosion, enabling the service life of both the joint and the pipe body to reach over 20 years
