Polyethylene spiral corrugated pipe reinforced by steel strip and process for manufacturing polyethylene spiral corrugated pipe

Abstract

The invention discloses a polyethylene spiral corrugated pipe reinforced by a steel strip. The polyethylene spiral corrugated pipe comprises a pipeline body. The pipeline body comprises two circular plates and a straight plate, the two circular plates are arranged on two sides of the straight plate, a sound absorption reinforcement layer is arranged between the two circular plates, stretch-resistant reinforcement layers are arranged on the outer wall of the pipeline body, a sealing layer is arranged on the outer walls of the stretch-resistant reinforcement layers and the sound absorption reinforcement layer, reinforcement filled layers are arranged between the sealing layer and the stretch-resistant reinforcement layers, and the steel strip is arranged outside the sealing layer. The polyethylene spiral corrugated pipe has the advantages that the single pipeline body is processed to obtain two pipelines, the two pipelines are parallel to each other, accordingly, the problem of easinessin rolling and loosening due to a single pipeline can be solved, water can be distributed, and single-road drainage or water supply pressures can be relieved; one of the pipelines still can be used even when the other pipeline is blocked, accordingly, the time can be gained for maintenance and pollution discharge, the integral pipelines are high in strength and can resist high and low temperatures, and noise can be reduced.

Description

technical field [0001] The invention relates to the field of a steel strip reinforced polyethylene spiral corrugated pipe and its manufacturing process, in particular to a steel strip reinforced polyethylene spiral corrugated pipe and its manufacturing process. Background technique [0002] With the sustained and stable high-speed growth of my country's national economy, it provides a good macro environment and broad space for urban infrastructure construction. With my country's increasing emphasis on environmental protection, governments at all levels from the central government to local governments have issued a series of policies and regulations on water conservation, pollution control and environmental protection. Water supply, water saving, drainage and sewage treatment will become the focus of urban municipal construction in the future, which provides market development space for the promotion and application of large-diameter plastic pipes. Because structural wall pi...

AI Technical Summary

Problems solved by technology

The double-wall corrugated pipes used in drainage and sewage pipes in my country have the advantages of good rigidity and low price; however, they also have the disadvantages of poor low-temperature impact performance, which are very easy to be damaged especially in winter construction in the north. In addition, pipes need to be extruded and difficult to produce Demolding, because the pipeline is cylindrical, it is inconvenient to transport and lay, and once it is blocked, the road will be submerged, and there are many disadvantages
