Composite pipe formed by winding plastic with netty steel belt and production method thereof

Abstract

The invention relates to a composite pipe formed by winding plastic with a netty steel belt and a production method of the composite pipe. Two layers of HDPE solid-wall pipes and the netty steel belt are heated and combined stably through butt-welding and adhesive resin, and the two ends of the composite pipe are respectively provided with a plastic solid wall sealing ring through hot melting. The composite pipe has the advantages of being far superior to a steel mesh framework plastic composite pipe in physical and mechanical property and chemical property; the hydraulic pressure resistance of the composite pipe formed by winding the plastic with the netty steel belt is 2.0 Mpa-8.0 Mpa, rejects are easy to recycle, and production efficiency is high; due to the design of the sealing rings, the situation that netty steel belt sections of ports of the pipe meets with water and are corroded and rusted when the pipe is stored indoors and outdoors is prevented; the compatibility between the special polymer adhesive resin and HDPE resin is high, machining is easy, and compressive strength is high.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a plastic composite pipe wrapped with mesh steel strips and a production method thereof. Background technique [0002] The steel wire used in the existing steel mesh skeleton plastic (polyethylene) composite pipe is: brass wire with a standard diameter of 0.5-1.0MM; the mesh size is greater than 3×3MM; the mesh size is wound on the pipe body by a turntable device. Most have the following disadvantages: [0003] 1. The mesh size of the brass wire in the pipe is difficult to ensure consistency during production, and the phenomenon of piled wire, broken wire and disordered wire is prone to occur, because the pipe speed and winding speed cannot be synchronized; [0004] 2. The reconnection between the inner and outer steel wires is in the form of points, and its peeling strength is low; [0005] 3. The defective products in production are not easy to recycle, the recycli...

Problems solved by technology

[0003] 1. The mesh size of the brass wire in the pipe is difficult to ensure consistency during production, and the phenomenon of piled wire, broken wire and disordered wire is prone to occur, because the pipe speed and winding speed cannot be synchronized;

[0004] 2. The reconnection between the inner and outer steel wires is in the form of points, and its peeling strength is low;

[0005] 3. The defective products in production are not easy to recycle, the recycling cost is high, and the production efficiency is low;

[0007] 5. When the inner and outer steel wires are wound, the disordered wire phenomenon is difficult to control, which affects the hydraulic resistance of the pipe.

[0008] 6. High and low temperature resistance, penetration resistance and hydraulic performance of pipes need to be improved
