Problems solved by technology

[0004] However, in some occasions with severe wear and corrosion, and where heat exchange is required, the inner lining layer is made of resin because of its poor thermal conductivity, while the bimetallic composite pipe is relatively poor in corrosion resistance. Not suitable for use in such working conditions

Abstract

The invention provides a production device and method for a graphene heat transfer enhanced multilayer composite pipe. The outer layer is a metal pipe, the middle layer is graphene / phenolic resin, and the inner layer is phenolic resin. The device is composed of an operation and control system, a hard pipe, a metal pipe rotating device, a baffle ring, a hard pipe supporting bearing, a steel wire brush, a metal pipe supporting frame, a composite resin nozzle, a resin nozzle, a transmission wheel, a heating curing device, a transmission belt, a moving motor, a moving guide rail, a resin pump, acomposite resin pump and a transition supporting pipe. The multilayer composite pipe is of a three-layer structure, the outer layer is the metal pipe, the middle layer is the phenolic resin added withgraphene, and the inner layer is a phenolic resin layer. The device has the beneficial effects of being high in production efficiency, compact in composite layer, high in bonding strength and the like.

Description

technical field [0001] The invention relates to a forming equipment for a composite pipe, in particular to a production device and method for a graphene heat transfer enhanced multilayer composite pipe. Background technique [0002] The outer layer and the inner lining of the composite pipe can be made of materials with different characteristics. The outer layer is responsible for bearing pressure and rigid support, and the inner lining is responsible for corrosion resistance and wear resistance. The outer pipe can choose metal pipes with different diameters and wall thicknesses according to the flow and pressure requirements of the conveying medium, such as: hot-dip galvanized steel pipes, straight seam welded pipes, spiral pipes, seamless steel pipes for low and medium pressure fluid transmission, high-pressure boilers And seamless steel pipes, line pipes, etc. for petroleum cracking. According to the chemical composition of the conveying medium, different corrosion-resis...
