Large-caliber lower pressure water feeding polythene wire mesh winding pipe and production method and production equipment

Abstract

The invention relates to a large-caliber lower pressure water feeding polythene wire mesh winding pipe which is characterized by comprising a solid wall pipe body layer and a protrusive reinforcing structure layer. The solid wall pipe body layer is composed of an inner wall layer, a reinforcing layer and an outer wall layer, the inner wall layer is a continuous inner wall layer which is formed in the mode that sheet-like polythene strips wind around a rotary drum mould spirally, the reinforcing layer is a steel wire mesh reinforcing layer which is formed in the mode that a steel wire mesh winds around the inner wall layer spirally, the outer wall layer is a continuous outer wall layer which is formed in the mode that sheet-like polythene strips wind around the rotary drum mould spirally, and the protrusive reinforcing structure layer is a protrusive reinforcing rib which is formed in the mode that tubular polythene strips which are used for wrapping a framework tube wind around the outer wall layer of the solid wall pipe body spirally. The large-caliber lower pressure water feeding polythene wire mesh winding pipe has a large caliber, can be used for delivering water from a great distance and has the advantages of being good in ring stiffness and good in internal pressure resistance. The production method of the large-caliber lower pressure water feeding polythene wire mesh winding pipe is simple, power consumption is little, the production equipment of the large-caliber lower pressure water feeding polythene wire mesh winding pipe has the advantages of being high in efficiency and stable in operation, and the large-caliber lower pressure water feeding polythene wire mesh winding pipe can be manufactured integrally on assembly lines.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes and their processing, and in particular relates to a large-diameter low-pressure water supply polyethylene wire mesh winding pipe, a production method and production equipment. Background technique [0002] At present, with the continuous development of water conservancy projects, especially the increasing number of long-distance water delivery processes, the quality and life of water supply pipes and fittings are more stringent. Some steel pipes with ordinary functional properties are gradually replaced by energy-saving and environmentally friendly pipes. The plastic pipes that have certain ring stiffness and can withstand internal pressure are recognized by the majority of users for their smooth inner wall, no scaling, small frictional resistance of water flow, large water delivery capacity, and low energy consumption. But at present, the production of plastic water supply pipes is mainly ...

AI Technical Summary

Problems solved by technology

The current extrusion molding process produces large-diameter pipes with high production costs. At the same time, because the joints are welded by plates, the welding equipment is heavy and the construction is inconvenient.
