Abstract
The invention discloses a steel-plastic composite pipe with ultra-high molecular weight. The pipe includes: a polyethylene layer with ultra-high molecular weight, an adhesive resin layer, a fibrous skeleton layer, an adhesive resin layer, a high density polyethylene layer, a steel-belt spiral winding protective layer and a modified polyethylene layer, which are arranged in order from inside to outside. The fibrous skeleton layer is a net-shaped skeleton structure formed by left and right spiral winding of high molecular carbon fiber filaments. According to the technical scheme of the invention, high molecular carbon fibers replace original coppered steel wire in the manufacturing of the skeleton layer, which reduces the weight of the composite pipe while the original performance is maintained. The armored steel belt spiral winding protective layer and a copper film layer on the inner wall of the steel belt spiral winding protective layer achieve an ultra-high protective stiffness, which can effectively prevent any kind of impact or damage. The modified polypropylene serves as the outermost layer of the composite pipe, which can effectively elevate ultra-wearing resistance of the composite pipe.
Description
technical field [0001] The invention relates to a pipe, in particular to a steel-plastic composite pipe. Background technique [0002] The steel-plastic composite pipe is made of high-strength copper-plated steel wire spirally wound around the mesh skeleton structure as the reinforcement, high-density polyethylene as the matrix, and uses high-performance high-density polyethylene to modify the bonding resin. Composite pipes formed by step-by-step extrusion have excellent wear resistance, pressure resistance, and crack resistance, and are widely used in long-distance buried fluid pipeline systems. Existing steel-plastic composite pipes cannot bear a large external impact force at the construction site, which is likely to cause permanent damage to the skeleton structure inside the composite pipe, thereby affecting the service life of the steel-plastic composite pipe, and the skeleton structure of the existing steel-plastic composite pipe The steel mesh skeleton used has the c...
