Abstract

The utility model relates to a polyethylene enhanced pipe made of wire rope enhanced polyethylene composite band, which essentially comprises an inner layer plastic pipe and an outer layer plastic pipe. A wire rope enhanced band is arranged between the inner layer plastic pipe and the outer layer plastic pipe. A plurality layers of wire rope enhanced bands are alternately wound around the outer layer of the inner layer plastic pipe by the opposite spiral direction of adjacent layers. The utility model has the advantages that the utility model adopts the wire rope enhanced polyethylene composite band to make the polyethylene enhanced pipe, the winding angle can achieve the most reasonable range, the usage of the wire can be reduced and the weight of the pipe can be decreased. Compared with the prior art, the polyethylene enhanced pipe has the advantages of simple operation, easy replacement of the product structure, wide ranges of application, etc.

Description

A kind of polyethylene enhancing tubing that strengthens the making of polyethylene compound strip by wire rope

Technical field

The utility model relates to the plastic tube field, mainly is that a kind of polyethylene of being made by wire rope enhancing polyethylene compound strip strengthens tubing, is applied to feedwater, draining, and combustion gas, chemical industry, oil, rock gas, agricultural, ground electric power pipe is buried, fields such as optical-fibre communications in the mine.

Background technique

Common polythene tubing is single polyethylene manufacturing, and not only consumptive material is many, and the tubing voltage endurance capability is low.Steel-wire carcass of the prior art strengthens the polyethylene compound pipe employing steel wire directly is coated on the pipe outside in the polyethylene, coats the making method of outer tube wall then.This method is owing to disposable on-line operation, and steel wire quantity is many, the broken string of each root steel wire, and faults such as random line all can cause the shutdown of equipment or the quality of product to descend; The continuous poor-performing that makes production; It is also relatively more difficult to operate.In addition, because the restriction of structure, the arrangement angle between winding steel wire and the tubing axis is too small, causes the axial and bigger defective of radial strength difference of goods.

The model utility content

The utility model purpose is exactly the deficiency that will overcome above-mentioned technology, strengthens the polyethylene enhancing tubing that the polyethylene compound strip is made and provide a kind of by wire rope.

The utility model solves the technological scheme that its technical problem adopts.This polyethylene enhancing tubing that strengthens the making of polyethylene compound strip by wire rope, mainly comprise inner layer plastic tube and outer layer plastic tube, be provided with the wire rope reinforcing band between described inner layer plastic tube and the outer layer plastic tube, multilayer wire rope reinforcing band is with staggered being wrapped on the outer wall of inner layer plastic tube of the opposite mode of adjacent layer Hand of spiral.

The tensile strength of described wire rope reinforcing band is higher than the tensile strength of inner layer plastic tube and outer layer plastic tube.

The wire rope reinforcing band comprises that strengthens a wire rope, is coated on the binder that strengthens the wire rope surface and coats the polyethylene layer that strengthens wire rope.

Bonding or the welding of the plastic materials of described inner layer plastic tube and outer layer plastic tube and wire rope reinforcing band is an one.

The effect that the utility model is useful is: the utility model adopts wire rope to strengthen the polyethylene compound strip and makes polyethylene and strengthen tubing, can make winding angle reach zone of reasonableness, can reduce the steel wire use amount, makes tubing weight saving.Compared with prior art, the utlity model has simple to operately, article construction is changed easily, advantages such as wide adaptability.At the goods requirement of different pressures grade, can adopt conversion reinforcing band wirerope diameter or wire rope quantity, and the method that changes winding layer quantity, reach usage requirement.Product can satisfy oil, rock gas, and chemical industry, the mine, the technical requirements of industry conveyance conduits such as metallurgy also can be satisfied municipal water supply, draining, the needs of agricultural irrigation simultaneously.Compare with common polythene tubing: under with equal pressure requirement situation, can save the polyethylene raw material greatly, and can reach the inaccessible working pressure of common polythene tubing, the less tubing goods (250mm) of specification are following can also make the plate-like product, reduce pipe joint, dwindle the construction period, save operating expenses.

Description of reference numerals: inner layer plastic tube 1, outer layer plastic tube 2, wire rope reinforcing band 3, the first strengthens belt 4, the second and strengthens belt 5.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

As depicted in figs. 1 and 2, this polyethylene enhancing tubing that strengthens the making of polyethylene compound strip by wire rope, mainly comprise inner layer plastic tube 1 and outer layer plastic tube 2, be provided with wire rope reinforcing band 3 between described inner layer plastic tube 1 and the outer layer plastic tube 2, the bonding or welding of the plastic materials of described inner layer plastic tube 1 and outer layer plastic tube 2 and wire rope reinforcing band 3 is an one.Multilayer wire rope reinforcing band 3 is with staggered being wrapped on the outer wall of inner layer plastic tube 1 of the opposite mode of adjacent layer Hand of spiral.Extrude processing through twice, multi-layer structure is closely as one, and has certain elasticity, and course of working can be batched and is plate-like.

Described wire rope reinforcing band 3 comprises that strengthens a wire rope, is coated on the binder that strengthens the wire rope surface and coats the polyethylene layer that strengthens wire rope.The tensile strength of wire rope reinforcing band 3 is higher than the tensile strength of inner layer plastic tube 1 and outer layer plastic tube 2.

The utility model adopts and makes the method production polyethylene reinforced pipe that wire rope strengthens the polyethylene compound strip in advance.This wire rope strengthens compound strip with the even level structure, and multilayer wire rope reinforcing band 3 comprises that first strengthens the belt 4 and the second enhancing belt 5 in the present embodiment.The mode of the reverse intersection of adjacent layer is wound in the inner layer plastic tube 1 wall outside, is the equilibrium that guarantees goods axial strength and radial strength, between reinforcing band and the tubing axis with 54 ° 44 ' about the angle arrangement.Meanwhile, adopt the method for hot melt knot, inner layer plastic tube 1 and the first enhancing belt 4 and second are strengthened between the belt 5 fuse into one, then tube wall is an one with strengthening the belt clinkering inside and outside coating outer layer plastic tube 2 walls make under the situation of the heating second enhancing belt 5 outer walls.

In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
