Abstract
The utility model relates to a high strength double-level wall tube, belonging to the pipeline. The pipe wall comprises a tube body, of which the inner and outer walls are smooth wall faces, wherein a layer of glass fiber is covered on the outer surface of the side wall of the tube body; and a layer of polyethylene film is covered outside the glass fiber. The glass fiber and the polyethylene film are covered outside the tube body; the glass fiber has high mechanical strength, better corrosion resistance and worse abrasive resistance; the polyethylene film covered outside the glass fiber effectively avoids wearing the glass fiber; the high density polyethylene film has big rigidity, hardness and mechanical strength; the strength of the pipeline is greatly improved by matching the glass fiber with the polyethylene film; the service life of the pipeline is prolonged; and the high strength double-level wall tube is suitable for more work occasions.
Description
Technical field
The utility model relates to a kind of pipeline, a kind of specifically high tenacity two flat walls pipe.
Background technique
Pipeline is the device that is used for the fluid of conveying gas, liquid or band solid particle.Having many uses of pipeline is general, mainly is used in feedwater, draining, blowdown, heat supply, gives gas, grows in distances oil and natural gas, agricultural irrigation, hydraulic engineering and the various commercial plant.In the actual using process of pipeline, small-bore pipeline generally adopts plastic tube, and traditional pure plastic pipe ring stiffness is not high enough; And the pipeline cost that new materials such as pure employing polyethylene are made is too high, and therefore the bigbore slightly pipeline steel that generally adopts steel to combine with plastics to produce is moulded pipe, under some occasions; The intensity that steel is moulded pipe still can not meet the demands; Need to adopt concrete duct, concrete duct is constructed and is safeguarded very inconvenience, improves steel and moulds the problem that the intensity of pipe remains needs solution.
The model utility content
The purpose of the utility model is to provide a kind of high tenacity two flat walls pipe, the raising greatly of this pipeline strength, long service life, applied widely.
The technological scheme that its technical problem of the utility model solution is taked is: high tenacity two flat walls pipe; Comprise that inside and outside wall is the body of hydraulically smooth surface; It is characterized in that described tube wall outer surface is coated with layer of glass, the outside of said glass fibre is coated with the layer of polyethylene film.
Described body rolls and constitutes by having steel band and no steel band that spiral is set at interval, and adjacent have steel band and a no steel band close adhesion; Described no steel band is the banded sheet material that is provided with hollow spine, and said spine extends along the length direction of banded sheet material, and described steel band is arranged is that hollow spine internal spiral at said banded sheet material is wound with the steel section bar; Banded sheet material both sides are the plane and form smooth inside and outside wall.
Described polyethylene film is that banded polyethylene helical rolls and forms.
Compared with prior art; The utlity model has following outstanding beneficial effect: be coated with layer of glass and layer of polyethylene film in the outside of body; The cooperation of glass fibre and polyethylene film has improved the intensity of pipeline greatly; Can prolong the working life of pipeline, adapt to the more work occasion.
Description of drawings
Fig. 1 vertically partly cuts open structural representation for the utility model.
Among the figure: 1 no steel band, 2 have steel band, 3 steel section bars, 4 glass fibres, 5 polyethylene films.
Embodiment
As shown in Figure 1.High tenacity two flat walls pipe comprises that inside and outside wall is the body of hydraulically smooth surface, and described tube wall outer surface is coated with layer of glass 4, and the outside of said glass fibre 4 is coated with layer of polyethylene film 5.
Described body rolls and constitutes by having steel band 2 and no steel band 1 that spiral is set at interval, and adjacent have steel band 2 and no steel band 1 close adhesion; Described no steel band 1 is for being provided with the banded sheet material of hollow spine, and said spine extends along the length direction of banded sheet material, and described have steel band 2 to be wound with steel section bar 3 for the hollow spine internal spiral at said banded sheet material; Banded sheet material both sides are the plane and form smooth inside and outside wall.
Described polyethylene film 5 forms for banded polyethylene helical rolls.This kind processing method helps the manufacturing of product; Promptly earlier polyethylene is pulled into band shape and at the poly side gluing of band shape; Take advantage of polyethylene and be in soft state following time its spiral is sticked on the outside of glass fibre 4, can closely be coated on the outside of glass fibre 4 after the polyethylene cooling moulding automatically.
Described polyethylene film 5 should use density polyethylene film with high, and glass fibre 4 mechanical strengths are high, good corrosion resistance, and shortcoming is that wear resistance is relatively poor; The polyethylene film 5 that is coated on glass fibre 4 outsides has effectively avoided glass fibre 4 to be worn; Density polyethylene film with high 5 rigidity, hardness and mechanical strength are big; The cooperation of glass fibre 4 and polyethylene film 5 has improved the intensity of pipeline greatly; Can prolong the working life of pipeline, adapt to the more work occasion.
The above; Some principles of the utility model just explain through diagrams; This specification be not be to the utility model be confined to shown in described concrete structure and the Applicable scope; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
Except that the said technical characteristics of specification, all the other technical characteristicss are those skilled in the art's known technology.
Claims (3)
1. high tenacity two flat walls pipe comprises that inside and outside wall is the body of hydraulically smooth surface, it is characterized in that described tube wall outer surface is coated with layer of glass, and the outside of said glass fibre is coated with the layer of polyethylene film.
2. high tenacity two flat walls pipe according to claim 1 is characterized in that, described body rolls and constitutes by having steel band and no steel band that spiral is set at interval, and adjacent have steel band and a no steel band close adhesion; Described no steel band is the banded sheet material that is provided with hollow spine, and said spine extends along the length direction of banded sheet material, and described steel band is arranged is that hollow spine internal spiral at said banded sheet material is wound with the steel section bar; Banded sheet material both sides are the plane and form smooth inside and outside wall.
3. high tenacity two flat walls pipe according to claim 1 and 2 is characterized in that, described polyethylene film is that banded polyethylene helical rolls and forms.
