Plastic-lined socket pipe and manufacturing process thereof

Abstract

Disclosed are a plastic-lined socket pipe and a manufacturing process thereof. The plastic-lined socket pipe comprises a round pipe body, a glue layer and a lining, and then the lining and the glue layer are made into a blank online, the blank is subjected to on-line operations via deformation, stretching, heating and expansion procedures, so that the round pipe body is integrally adhered with lining plastic, and the defects of unsmooth inner wall, high water flow resistance, proneness to scaling, influence brought by reacting substances generated by hardening of cement on water quality, large lining thickness, low water delivery efficiency, difficulty in installation and construction, high manufacturing difficulty, equipment complexity, high cost and the like due to that fact that an existing common hard round pipe uses a cement mortar lining or epoxy ceramic lining are overcome; the plastic-lined socket pipe is suitable for water delivery, gas delivery and oil delivery of various municipal projects and industrial and mining enterprises and particularly suitable for water supply of the municipal projects, and is a preferable water delivery pipe product.

Description

technical field [0001] The invention relates to a lined plastic socket intubation tube and its manufacturing process. Background technique [0002] The existing ordinary hard round pipes are often used as pipelines for water supply, gas supply, and oil supply because of their good comprehensive performance such as compression resistance and low cost. However, the smoothness of the inner wall of this type of pipeline is not high , poor anti-corrosion performance, which directly affects the traffic efficiency. In order to solve the traffic problems such as smoothness and anti-corrosion of the inner wall of the hard round pipe, the most common method is to use cement mortar lining or epoxy ceramic lining in the hard round pipe. The preferred anti-corrosion and high-gloss smoothing method for this type of pipeline; use cement mortar lining as a drinking water delivery pipeline, because the inner wall is still not smooth, the water flow resistance is large, and it is easy to scal...

Problems solved by technology

[0002] The existing ordinary hard round pipes are often used as pipelines for water supply, gas supply, and oil supply because of their good comprehensive performance such as compression resistance and low cost. However, the smoothness of the inner wall of this type of pipeline is not high , poor anti-corrosion performance, which directly affects the traffic efficiency. In order to solve the traffic problems such as smoothness and anti-corrosion of the inner wall of the hard round pipe, the most common method is to use cement mortar lining or epoxy ceramic lining in the hard round pipe. The preferred anti-corrosion and high-gloss smoothing method for this type of pipeline; use cement mortar lining as a drinking water delivery pipeline, because the inner wall is still not smooth, the water flow resistance is large, and it is easy to scale, and the reaction substances produced by cement hardening affect the water quality. The thickness is 3-12mm, that is, the inner lining is thicker and the water delivery efficiency is lower. The cement lining will increase the weight of the entire pipe body, which is not conducive to construction and installation. Moreover, the cement lining is inconvenient to process and has poor adhesion. There are still many difficulties to be solved in the cement lining, so the cement lining is a less effective lining method; the epoxy ceramic lining is used, although it will have high adhesion and smoothness, but the manufacturing Difficult, complex equipment, high cost, can only be used for special projects, can not be widely used
