Abstract
The utility model provides a corrugated pipe wound with metal strips, which is provided with a corrugated outer layer pipe wall, a smooth inner layer pipe wall and spiral wound plastic-coated punched metal strips arranged between the outer and the inner layer pipe walls. The utility model effectively improves the binding and rustproof performance between the metal strips and the plastic pipe wall, therefore, as a firm and durable pipeline, the utility model is suitable for being laid underground for large displacement of drainage and sewerage.
Description
Technical field
The utility model belongs to the tubing field, particularly relates to a kind of steel band winding corrugated pipe with heavy caliber down blow draining compatibly.
Technical background
The tubing that heavy caliber blowdown at present, draining are used has module moulding bellows, all-plastic winding corrugated pipe and steel band winding corrugated pipe.Utilize module moulding bellows manufacturing mechanism to need complicated block motion and production technology, make the manufacturing of equipment and difficult in maintenance, and the equipment cost costliness, its complicated production technology brings very big difficulty also for the production debugging of tubing; The winding corrugated pipe equipment of all-plastic is simple relatively, but to greater than 1000 millimeters tubing, ring stiffness will reach the SN8 plastic layer will become very thick, and the tubing cost is very high, and the tubing of basically can not production requirement higher SN12.5.
Existing steel band winding corrugated pipe is by undulatory outer wall and level and smooth inner layer tube wall and be clipped in the steel band that the spiral between the internal and external layer tube wall communicates and form.Tubing all is bonded together by tackiness agent by the corrugated steel band and forms, the strength and toughness that is to say tubing depends on the degree of adhesion of tackiness agent to a great extent, use a period of time, because the influence of surrounding environment, difference of thermal expansion coefficients between steel band and the plastics is too big, occurs segregation phenomenon between steel band and the plastic layer easily.Add steel band to be affected by the external environment easily and get rusty, will certainly cause harmful effect tubing.
So must develop and a kind ofly can satisfy heavy caliber and produce needs, the tubing that good bond and effectively preventing is got rusty between steel band and the plastic layer.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, proposes a kind of firm durable steel band winding corrugated pipe.
The technical solution adopted in the utility model is as follows:
A kind of steel band winding corrugated pipe comprises having undulatory outer wall and level and smooth inner layer tube wall, and is clipped in the steel band that the spiral between the internal and external layer tube wall communicates that described steel band is provided with through hole, and the steel band outer surface is coated with plastic coating.
In the technique scheme, the interlayer steel band of described steel band winding corrugated pipe is that spiral twines, by punching to steel band, play the effect that connects undulatory outer wall and level and smooth inner layer tube wall, thereby skin, interlayer steel band and internal layer three form integrative-structure, and the steadiness of the tubing after the moulding is effectively guaranteed like this.
Described inner layer tube wall twines overlap joint by the strip plastic tape and forms, and described steel band is pressed in the lap-joint of inner layer tube wall.Because inner layer tube wall all is by twining shaped by lapping, in the easiest quality problems that occur of lap-joint, so steel band is pressed in this lap-joint, efficiently solving this problem in Wrapping formed process.
Described steel band is " U " type, and is wound in the outer wall inboard.Because outer wall is corrugated, so steel band is " U " type with better and outer wall is bonding.
Most typical structure is that described steel band is " U " type, and is coated among the outer wall.
Steel strip surface of the present utility model is also handled through annular knurl, forms the reticulate pattern that increases friction.For steel band and plastic layer can combine better, by annular knurl, increase the rubbing action between steel band and the plastic layer to steel strip surface, improve the steel strip surface adhesive power, can make that also the tubing after the moulding is more firm.
Described steel band is also handled through phosphatization, forms the phosphate conversion film in steel strip surface, can improve the corrosion-resisting function of steel band and the adhesion of rete.
The beneficial effects of the utility model are as follows:
(1), the utility model connects the outer and internal layer formation integrative-structure of tubing, the steadiness of raising tubing by Punching steel strip;
(2), the utility model improves frictional force between itself and the plastic layer by the annular knurl to steel strip surface, makes between steel band and the tubing bonding closelyr, be not easy to be stripped from;
(3), the utility model is by handling the phosphatization of steel strip surface, effectively improve the anticorrosive effect of tubing and improve steel band and plastic layer bonding effect.
Description of drawings
Fig. 1 is the Punching steel strip structural representation after handling through phosphatization, annular knurl;
Fig. 2 is a plastic-coated Punching steel strip structural representation;
Fig. 3 is a steel band winding corrugated pipe structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Structural representation of the present utility model as shown in Figure 3, the steel band winding corrugated pipe has undulatory outer wall 2 and level and smooth inner layer tube wall 1 and is clipped in the plastic-coated Punching steel strip 3 that the spiral between the internal and external layer tube wall twines to be formed.
The structure of the steel band 3 after the moulding is the spiral winding as shown in Figure 2, and its surface has plastic coating, promptly has outer layer plastic coating 33 and inner plastic coating 31.
Claims (6)
