Rigid corrugated composite pipe and manufacturing method of rigid corrugated composite pipe

Abstract

The invention discloses a rigid corrugated composite pipe, which comprises an outer layer modified plastic pipe with the smooth outer surface, wherein an inner layer metal rigid corrugated pipe is pasted and covered in the outer layer modified plastic pipe, and an inner wall anti-corrosion layer also coats the inner surface of the inner layer metal rigid corrugated pipe. The invention also discloses a manufacturing method of the rigid corrugated composite pipe. Though the inner wall anti-corrosion layer and the outer layer modified plastic pipe, the contact between the inner layer metal rigid corrugated pipe and the outside air is completely avoided, the corrosion probability of the inner layer metal rigid corrugated pipe is reduced, and the service life of the composite pipe can be favorably prolonged; the inner layer metal rigid corrugated pipe can also improve the radial intensity of the composite pipe, so that the composite pipe can bear greater pressure; through the arrangement of the inner layer metal rigid corrugated pipe, the inner corrugations can be used for realizing the connection among greenhouse frameworks, the connection is very firm, the toughness and the torque-resistant capability are also enhanced, and the rigid corrugated composite pipe is more suitable to be used in regions with strong wind. The rigid corrugated composite pipe can be freely cut according to requirements and can be fast fixed and installed, and the standardized and scaled manufacturing, construction and application are favorably realized.

Description

technical field [0001] The invention relates to a composite pipe, and also relates to a manufacturing method of the composite pipe. Background technique [0002] Traditional bamboo poles or wooden poles are commonly used as frameworks in fruit and vegetable greenhouses, greenhouses, and fences in the prior art, but bamboo poles and wooden poles have small radial rigidity, are not easy to bend and shape to meet the needs of greenhouses, and have poor corrosion resistance. , the above factors cause its short service life and high frequency of replacement. With the development and promotion of technology, some users also use galvanized steel pipes, PVC pipes and magnesite cement skeletons to replace bamboo and wooden poles, but they still cannot solve some old problems of using bamboo and wooden poles, and some new ones have emerged. Problems, such as the corrosion of the welding and joints of galvanized steel pipes, cannot be solved. At the same time, the galvanizing process ...

Problems solved by technology

[0002] Traditional bamboo poles or wooden poles are commonly used as frameworks in fruit and vegetable greenhouses, greenhouses, and fences in the prior art, but bamboo poles and wooden poles have small radial rigidity, are not easy to bend and shape to meet the needs of greenhouses, and have poor corrosion resistance. , the above factors cause its short service life and high replacement frequency

With the development and promotion of technology, some users use galvanized steel pipes, PVC pipes and magnesite cement skeletons to replace bamboo poles and wooden poles, but they still cannot solve some old problems of using bamboo poles and wooden poles, and some new ones have emerged. Problems, such as the corrosion problem of the welding and joints of galvanized steel pipes cannot be solved, and the galvanizing process has serious environmental pollution, while the rigidity and strength of PVC pipes are low, and the skeleton of magnesite cement is too heavy

The more prominent problem is that the connection and installation of the above-mentioned several materials are not firm, and often cause damage at the connection. When used in a strong wind area, the safety is poor, and it is easy to be blown down by the strong wind. At the same time, its strength is also low. Resist the pressure of heavy snow, so it is not conducive to standardization, large-scale manufacturing, construction and application
