Steel wire veined plastic composite pipe and manufacturing method and device thereof

Abstract

A steel wire veined plastic composite pipe comprises an inner pipe wall and an outer pipe wall, wherein an empty cavity is formed between the inner pipe wall and the outer pipe wall; the inner pipe wall is an integrated pipe wall, and first steel wires are embedded into the inner pipe wall; a first engaging area which is formed by spirally coiling a plastic steel plate strip is formed in the innerpipe wall; the outer pipe wall is provided with a second engaging area which is formed by spirally coiling the plastic steel plate strip; an upper plastic plate strip and a lower plastic plate stripare correspondingly arranged in each of the first engaging area and the second engaging area; and second steel wires are embedded between two plastic plate strips in the second engaging area. A devicefor manufacturing the composite pipe is characterized in that the composite pipe can be manufactured by one process, so that the production efficiency is increased more than twice as that in the prior art; and the device has the advantage of being easy to operate; and meanwhile, the device is long in service life, simple to repair, etc.

Description

technical field [0001] The invention relates to a pipe, which is a steel wire vein plastic composite pipe and a preparation method and equipment thereof. Background technique [0002] Drainage pipes buried in the ground require appropriate ring stiffness. Therefore, steel strips are usually used to enhance the ring stiffness of polyethylene drainage pipes. For example: more commonly used polyethylene corrugated pipes, double-flat-wall plastic-steel composite winding pipes, and plastic-steel structural wall winding pipes. However, although these pipes have their own advantages, their disadvantages are also obvious: due to the limited tensile strength and elastic modulus of steel strips, more steel strips are needed to meet the requirements, and the product cost is high, especially for large-diameter pipes. Thicker steel strips are required to increase the ring stiffness of the pipe body. Moreover, the production process of these pipes is discontinuous, the production effici...

Problems solved by technology

However, although these pipes have their own advantages, their disadvantages are also obvious: due to the limited tensile strength and elastic modulus of steel strips, more steel strips are needed to meet the requirements, and the product cost is high, especially for large-diameter pipes. Thicker steel strips are required to increase the ring stiffness of the pipe body

Moreover, the production process of these pipes is discontinuous, the production efficiency is low, the environment is polluted, etc.
