Steel belt reinforced ultra-high molecular weight polyethylene membrane composite pipe and preparation method thereof

Abstract

The invention relates to the technical field of composite pipes, in particular to a steel strip reinforced ultra-high molecular weight polyethylene membrane composite pipe and a preparation method thereof.The steel strip reinforced ultra-high molecular weight polyethylene membrane composite pipe comprises a machining table and a pipe forming mechanism, the pipe forming mechanism is composed of a forming cylinder, a mounting bolt, a controllable inner core, an electrifying pipe, a synthesis area and an injection molding hole, and the controllable inner core is composed of memory alloy; the controllable inner core is composed of an electric heating wire and a piezoelectric plate. An ultra-high molecular weight polyethylene fluid is added into the injection molding hole, so that the ultra-high molecular weight polyethylene fluid flows into the synthesis area, and an electric heating wire is electrified through a power box and an electrifying pipe; the controllable inner core is heated to a high-temperature state so as to deform, so that the deformation force of the controllable inner core is utilized to form external expansion type extrusion, the ultrahigh molecular weight polyethylene fluid is extruded and attached to the inner wall of the steel belt composite pipe, and the ultrahigh molecular weight polyethylene fluid is tightly connected with the steel belt composite pipe; the impact resistance, the corrosion resistance, the wear resistance and the like of the composite pipe are greatly improved.

Description

technical field [0001] The invention relates to the technical field of composite pipes, in particular to steel strip reinforced ultra-high molecular weight polyethylene membrane composite pipes and a preparation method thereof. Background technique [0002] Composite pipe is a pipe based on metal and thermoplastic composite structure, lined with non-metallic materials such as plastic polypropylene, polyethylene or externally welded cross-linked polyethylene, which has the advantages of metal pipes and non-metal pipes. [0003] Since the strength of polyethylene pipes cannot meet certain requirements for use, when manufacturing large-diameter polyethylene pipes, a layer of steel belt is compounded on its periphery to achieve the purpose of enhancing the strength of polyethylene pipes. However, due to manufacturing costs and manufacturing methods, etc. Restricted by the aspect, the composite of steel can usually only be made of steel sheet materials. For pipes with special cal...

[0003] Since the strength of polyethylene pipes cannot meet certain requirements for use, when manufacturing large-diameter polyethylene pipes, a layer of steel belt is compounded on its periphery to achieve the purpose of enhancing the strength of polyethylene pipes. However, due to manufacturing costs and manufacturing methods, etc. Restricted by many aspects, steel composites can usually only be made of steel sheet materials. For pipes with special diameters and special purposes, their strength, elastic modulus and ring rigidity are still difficult to meet high standards.
