Abstract
The utility model relates to a flanged connection-type polythene spiral corrugated pipe reinforced by a metal strip. The spiral corrugated pipe comprises a pipe body including an outer polythene layer, the metal strip and an inner polythene layer; the metal strip is coated between the outer polythene layer and the inner polythene layer; injection molding flanges are arranged at both ports at two ends of the pipe body; and a steel flange plate is arranged on the outer wall of each injection molding flange. The spiral corrugated pipe has the benefits that the cost is low; manual labor cost is reduced; the efficiency and the leak tightness are high; and 100 percent leakage prevention is realized. Therefore, the spiral corrugated pipe can be used as an underground methane gas exhaust pipe in a coal mine and a buried water drainage pipe.
Description
Technical field
The utility model relates to the plastic tube processing technique field, relates in particular to a kind of flange join type steel band reinforced polyethylene spiral ripple pipe.
Background technique
The pipeline that is used for gas extraction at present mainly contains steel pipe, Glass Steel Tube, pvc pipe, colliery with steel band reinforced polyethylene spiral ripple pipe etc.Though these pipelines can reach some basic demands of gas extraction, difficult installation in the using process of down-hole, and the reduction of the reliability of weld seam, closed-water test does not reach requirement especially.The Placement that existing steel band reinforced polyethylene spiral ripple pipe is used has: hot melt is extruded connection, Electric thermal smelting belt connection, shrink belt connection, clip connected etc.These several kinds of Placements exist all that the easy seepage of interface, poor reliability, construction are difficult for, the high deficiency of cost, and can influence the duration, later stage even cause the road surface to subside easily.
The model utility content
The purpose of the utility model provides a kind of flange join type steel band reinforced polyethylene spiral ripple pipe, to overcome the above-mentioned deficiency of present existing product.
The purpose of the utility model is to realize through following technological scheme:
A kind of flange join type steel band reinforced polyethylene spiral ripple pipe; Comprise the helical bellows body of forming by outer layer polyethylene layer, steel band and inner layer polyethylene layer; Said steel band is coated between outer layer polyethylene layer and the inner layer polyethylene layer; Port, said helical bellows body two ends is equipped with the injection moulding flange, and injection moulding flange outer wall is provided with the steel flanges dish.
The beneficial effect of the utility model is: cost is low, practices thrift human cost, and efficient is high, and good airproof performance can accomplish that 100% is non-leakage, can be used for coal mine gas exhaust column, buried drain pipe.
