Abstract
The invention relates to a flange connection type steel band reinforced polyethylene spiral corrugated pipe. The flange connection type steel band reinforced polyethylene spiral corrugated pipe comprises a spiral corrugated pipe body comprising an outer polyethylene layer, a steel band and an inner polyethylene layer, wherein the steel band is arranged between the outer polyethylene layer and the inner polyethylene layer in a covering manner; injection-molding flanges are arranged at two end ports of the spiral corrugated pipe body, and steel flange plates are arranged on outer walls of the injection-molding flanges. The flange connection type steel band reinforced polyethylene spiral corrugated pipe has the benefits as follows: the cost is low, the human cost is saved, the efficiency is high, the sealing performance is good, 100% leakage prevention can be realized, and the spiral corrugated pipe can be used as an underground coal mine gas exhaust pipe and an underground drainage pipe.
Description
Technical field
The present invention relates to plastic tube processing technique field, particularly relate to a kind of flanged connection-type polythene.
Background technique
Pipeline at present for gas extraction mainly contains steel pipe, Glass Steel Tube, pvc pipe, colliery steel band reinforced polyethylene spiral ripple pipe etc.Although these pipelines can reach some basic demands of gas extraction, in the using process of down-hole, install difficulty, and the reliability of weld seam reduces, closed-water test does not reach requirement especially.The Placement of existing steel band reinforced polyethylene spiral ripple pipe application has: hot-melt extruded connection, Electric thermal smelting belt connection, shrink belt connection, clip connected etc.This several Placement all exist the easy seepage of interface, poor reliability, construction not easily, high in cost of production is not enough, and can affect the duration, the later stage even easily causes road surface to subside.
Summary of the invention
The object of this invention is to provide a kind of flanged connection-type polythene, to overcome the above-mentioned deficiency of current existing product.
The object of the invention is to be achieved through the following technical solutions:
A kind of flanged connection-type polythene, comprise the helical bellows body be made up of outer polyethylene layers, steel band and inner layer polyethylene layer, described steel band is coated between outer polyethylene layers and inner layer polyethylene layer, port, described helical bellows body two ends is equipped with injection molded flange, and injection molded flange outer wall is provided with steel flanges dish.
Beneficial effect of the present invention is: cost is low, and save human cost, efficiency is high, good airproof performance, can accomplish that 100% is non-leakage, can be used for coal mine gas exhaust column, buried drain pipe.
Embodiment
Flanged connection-type polythene described in the embodiment of the present invention, comprise the helical bellows body be made up of outer polyethylene layers, steel band and inner layer polyethylene layer, described steel band is coated between outer polyethylene layers and inner layer polyethylene layer, port, described helical bellows body two ends is equipped with injection molded flange, and injection molded flange outer wall is provided with steel flanges dish.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but any change is done in its shape or structure; every have identical with the application or akin technological scheme, all drops within protection scope of the present invention.
Claims (1)
1. a flanged connection-type polythene, comprise the helical bellows body be made up of outer polyethylene layers, steel band and inner layer polyethylene layer, described steel band is coated between outer polyethylene layers and inner layer polyethylene layer, it is characterized in that: port, described helical bellows body two ends is equipped with injection molded flange, and injection molded flange outer wall is provided with steel flanges dish.
