Problems solved by technology

At present, the large-diameter drainage pipes on the market are almost all steel-plastic composite products. These steel-plastic composite drainage pipes are mostly non-pressure structure pipes, and they all have sufficient ring stiffness to support the external load of the soil and ensure long-term safe use. However, they cannot be used as Used in pipelines for conveying liquid under pressure

Embodiment Construction

[0041] figure 1 It is a schematic diagram of the traditional steel mesh skeleton tube structure.

[0042] figure 2 It is a schematic diagram of the structure of a traditional polyethylene plastic-steel winding pipe.

[0043] Such as image 3 Shown, a kind of steel-plastic strip comprises extruded strip body 21', and vertical steel rib 22 is inlaid in the internal rib of strip body, and vertical steel rib is steel belt substantially; The anti-corrosion performance of the plastic and the rigidity of the vertical steel rib are used to ensure the ring rigidity of the buried pipe.

[0044] Simultaneously at the side junction of strip body 21 ', lap joint structure 23 is adopted, so that when adjacent strip bodies are combined, the contact area when the two sides are bonded is greatly increased, and when the pipe is bonded, it is firmer and greatly Improves the joint strength of the pipe.

[0045] Such as Figure 4 as shown,

[0046] A plastic-steel winding pipe base 24 is f...

Abstract

The invention provides a double composite plastic steel composite pipe and a manufacture method thereof, discloses a liquid conveying pipeline with the advantages of high annular rigidity, low material consumption, capability of bearing internal pressure, favorable sanitary performance, long service life, and better comprehensive performance, and further discloses a manufacture method of the pipe. The composite pipe comprises an inner plastic steel wound pipe layer, a middle steel wound layer and an outer plastic layer, wherein the plastic steel wound pipe layer is formed by winding and bonding plastic steel belts; due to the adoption of the steel wound layer, both the anti-corrosion performance of plastic and the rigidity of steel belts are utilized; due to the adoption of the embedded steel wire, the internal pressure bearing performance of a buried pipe can be guaranteed; due to the composite structure of the pipe, the consumption of plastic is reduced, and the performance-price ratio of the pipe is greatly improved; and the manufacture method can be used for manufacturing large caliber liquid conveying pipelines, so as to solve the problem that the manufacture of large caliber plastic pipes is difficult in China.

Description

technical field [0001] The patent of the invention relates to a method for manufacturing a double-composite steel-plastic composite pipe, which is a large-diameter composite pipe, and the pipe is mainly used in the field of liquid transportation. Background technique [0002] At present, polyethylene plastic pipes have been widely used in domestic water supply pipelines. The characteristics of this pipe are very prominent, with long service life and excellent corrosion resistance. In addition, no heavy metal salt stabilizers are added to polyethylene pipes during processing, and the material is non-toxic. In addition, it It will not promote the growth of algae, bacteria or fungi, which better solves the problem of secondary pollution of drinking water in cities and towns, and has good hygienic performance. Because it is an all-plastic pipe, when meeting the operating pressure and resisting external pressure (ring stiffness), the wall thickness of the pipe is generally thicke...
