A method for manufacturing a hollow-walled plastic-steel winding drainage pipe

Abstract

The invention relates to a hollow wall plastic steel wound drainage pipe material and a manufacturing method thereof. The hollow wall plastic steel wound drainage pipe material comprises blending materials and high-strength steel belts, wherein the peripheries of the high-strength steel belts are wrapped by the blending materials. The manufacturing method includes the steps that the blending materials are manufactured, and corresponding high-strength steel belts are selected to be installed in a belt hanging machine and opened, enter a steel belt straightener and are heated through a high-frequency heater; the steel belts enter a cladding mold, the blending materials are added, and then the steel belts are placed in a high-speed mixer to be stirred; after stirring is completed, the steel belts are placed in an extruder to extrude the clad steel belts, the steel belts are pulled and cooled, and vacuum sizing is carried out on the steel belts; under the action of a belt sending machine, the steel belts are fed into a winding cage to be wound; rotational traction is added, the steel belts at cutting positions are picked off, cutting finishing is conducted, and the steel belts are examined and put in storage after completing. The plastic steel composite pipe material manufactured through the method has an excellent mechanical property, abrasion resistance and ageing resistance, and is good in toughness, high in ring stiffness, resistant to high and low temperatures, long in service life, good in basis adaptability and sealing performance and suitable for production and market promotion on a large scale.

Description

technical field [0001] The invention relates to a drainage pipe, in particular to a hollow-wall plastic-steel wound drainage pipe with high rigidity and strong basic adaptability, and a manufacturing method thereof. Background technique [0002] Polyethylene plastic-steel winding drainage pipe is a new type of polymer steel-plastic composite pipe product. It is made of steel-plastic composite special-shaped strip by spiral winding and welding, and its inner wall is smooth and flat. This kind of pipe has the advantages of corrosion resistance, light weight, easy installation and large flow rate. It can replace pipes made of high energy consumption materials such as cement, cast iron, ceramics, etc. It is an environmentally friendly green product, but the existing steel-plastic composite pipe ring stiffness Low, poor basic adaptability, poor steel-plastic adhesion, affecting the service life of the steel-plastic composite pipe. SUMMARY OF THE INVENTION [0003] In ord...
