Description
Technical Field
The utility model relates to a tubular product especially relates to a fine reinforcing winding shaping pressure pipe of heavy-calibre glass.
Background
The plastic pipe is widely applied to municipal buried water supply, building buried domestic water supply, buried fire water supply, industrial sewage discharge (pressure pipe), and industrial acid-base solution and powder or slurry conveying. The composite pipe is generally divided into an inner layer plastic pipe and an outer layer plastic pipe, and reinforcing steel wires or glass fibers are wound between the inner layer plastic pipe and the outer layer plastic pipe to achieve the purposes of increasing the strength and the durability of the pipeline and the like. The production process of the product has very high requirements on winding equipment, the caliber of the winding equipment is usually about 5 times of that of a pipeline, the equipment is very large, the equipment cost is high, the maintenance is difficult, and particularly for pipelines with large calibers, the existing winding equipment is difficult to complete winding work.
The Krah pipe is a high-density polyethylene (HDPE) winding structure wall pipe formed by hot winding. The wall pipe is a special structure wall pipe with high external pressure resistance, which is prepared by taking high-density polyethylene resin as a main raw material, adopting a thermal winding forming process and taking a polypropylene (PP) single-wall corrugated pipe as a supporting structure. The pipe can well solve the production process problem of the large-diameter pipeline, but the flat material belt part of the pipe is made of common polyethylene resin, and the seam parts are connected in a hot melting mode, so that the Krah pipe can only be used in the place resisting external pressure generally, and when materials generating internal pressure are conveyed inside the pipeline, the internal pressure resistance of the Krah pipe is insufficient, cracks are easily generated, and the pipe is broken.
