Abstract

The utility model relates to a plastic composite pipe of a reinforced continuous steel wire mesh framework, which mainly solves the problems of severe corrosion of pipelines, short service life and high maintenance cost. The plastic composite pipe is characterized in that a reinforced layer (2), a corrosion proofing layer (4), an insulating layer (5) and a compression resistant layer (6) are arranged outside a polyethylene medium feeding layer (1) in sequence. The plastic composite pipe has the characteristics of corrosion resistance, easy installation, long service life, low installation cost and continuity.

Description

Strengthen continuous steel wire mesh frame plastic composite tube

Technical field:

The utility model relates to a kind of composite pipe that liquid is carried, continuous steel wire mesh frame plastic composite tube of particularly a kind of enhancing of being used for.

Background technique:

Metal tubes or the nonmetal multiple tubes of adopting are carried in oil field, mine liquid more, and metallic conduit is when carrying liquid, and corrosive pipeline is serious, some races occur, emit, phenomenon such as leakage, and working life is short; But not metal composite pipe is then produced, installation cost is higher; In coastal or these pipeline construction difficulties of wetland, soldering point is many, and the maintenance cost height has seriously restricted the application of these pipelines

The model utility content:

Technical problem to be solved in the utility model is to overcome the problem that the corrosive pipeline that exists in the background technique is serious, working life is short, maintenance cost is high, and providing a kind of enhancing continuous steel wire mesh frame plastic composite tube, this strengthens, and continuous steel wire mesh frame plastic composite tube has anticorrosive, easy installation, the life-span is long, installation cost is low and successional characteristics.

The invention for solving the technical problem can reach by following technical solution: this strengthens continuous steel wire mesh frame plastic composite tube and comprises the polyethylene dielectric transport layer, is followed successively by enhancement layer, anticorrosive coat, thermal insulation layer, resistance to compression layer in polyethylene dielectric transport layer outside.

Each interlayer of described polyethylene dielectric transport layer, enhancement layer, anticorrosive coat, thermal insulation layer, resistance to compression layer is bonding; Described enhancement layer surface is surrounded by rubberised layer; The described enhancement layer that is surrounded by rubberised layer has two-layer; Described enhancement layer is the enhancement layer of braiding Coppered Steel Wire.

The utility model is compared with the above-mentioned background technology can have following beneficial effect: this polyethylene dielectric transport layer outside that strengthens continuous steel wire mesh frame plastic composite tube is followed successively by enhancement layer, rubberised layer, anticorrosive coat, thermal insulation layer, the resistance to compression layer, adopt the bonding design concept that combines with steel wire mesh frame plastic composite tube of interlayer high pressure, design length on demand, tie point is few, have the common feature of steel pipe and plastic pipe concurrently: shock-resistant, compressive resistance, anticorrosive, easily install, life-span is long, continuity, has detectivity, fed sheet of a media is not produced pollution, storing is convenient, and installation cost is low.

Description of drawings:

Accompanying drawing 1 is a cross sectional representation of the present utility model;

Accompanying drawing 2 is structural representations of another embodiment of the utility model.

Among the figure: 1-polyethylene dielectric transport layer, 2-enhancement layer, 3-rubberised layer, 4-anticorrosive coat, 5-thermal insulation layer, 6-resistance to compression layer.

Embodiment:

Below in conjunction with accompanying drawing will the utility model is described in further detail:

Accompanying drawing 1 is in conjunction with shown in Figure 2, and this strengthens continuous steel wire mesh frame plastic composite tube and comprises polyethylene dielectric transport layer 1, is followed successively by enhancement layer 2, anticorrosive coat 4, thermal insulation layer 5, resistance to compression layer 6 in polyethylene dielectric transport layer 1 outside.Described polyethylene dielectric transport layer 1 adopts high temperature resistant enhancing polyethylene by the high temperature extruding and moulding; Described enhancement layer 2 plays the pressure-bearing effect for the Coppered Steel Wire of braiding; There is rubberised layer 3 on described enhancement layer 2 surfaces; According to the needs of pressure design grade and production, that the described enhancement layer 2 that rubberised layer 3 arranged can have is two-layer, three layers or four layers; Described anticorrosive coat 4 materials are high-density polyethylene resins; Be incubated compoundly with thermal insulation layer 5 in that anticorrosive coat 4 is outside, guarantee pipeline when the conveying high-temp liquid, temperature leak is few; At the thermal insulation layer 5 outside one deck resistance to compression layers 6 that coat, the outside pressure that thermal insulation layer 5 is produced of opposing reduces thermal insulation layer 5 distortion; Each interlayer of described polyethylene dielectric transport layer 1, enhancement layer 2, rubberised layer 3, anticorrosive coat 4, thermal insulation layer 5, resistance to compression layer 6 is bonding, makes steel wire and plastics become one, guarantees the tubing integrality, makes that the tubing overall performance is more superior, and structure is more firm.

This strengthens continuous steel wire mesh frame plastic composite tube is corrosive liquids or gas specific pipe, the withstand voltage 16Mpa that can reach, the internal layer smooth abrasion-proof, be more than 4 times of steel pipe, greatly saved the cost in oil field or mine greater than 30 years working life, guarantee the steady quality of transported substance, pipe-line maintenance is convenient, and quick construction does not produce pollution, storing conveniently to fed sheet of a media.
