Abstract
A two-wall corrugated pipe belongs to the technical field of conveying pipelines, adopts a hollow two-layer pipe, and is used for water supply, water drainage, pollution discharge, air exhaust, subway ventilation, mine ventilation, farm irrigation, and the like. The corrugated pipe consists of an outer wall with an annular corrugated structure and a smooth inner wall, smooth flaring openings are arranged at the two ends of the corrugated pipe respectively, and the corrugated pipe is formed and manufactured by economically pressing HDPE (high-density polyethylene) which is adopted as a main raw material. In the two-wall corrugated pipe formed by adopting the technology, the two layers can both be thin layers, therefore raw material is saved, the manufacturing cost is reduced, the weight of the product corrugated pipe is greatly reduced, the conveying is convenient, and the mounting is labor-saving. The annular corrugated structure of the outer layer enables the whole corrugated pipe to be attractive in appearance, the smooth structure of the inner layer enables resistance to be small and flow rate to be high, and the HDPE adopted as the raw material is acid- and alkali-resistant and corrosion-proof, therefore the service life of the corrugated pipe is prolonged and the corrugated pipe is liked by customers.
Description
Technical field
The utility model belongs to the conveyance conduit technical field, is specifically related to a kind of aesthetic in appearance and double-wall corrugated pipe that comprehensive cost is low rational in infrastructure.
Background technique
Conveyance conduit is widely used in water supply, draining, blowdown, exhaust, subway ventilation, mine ventilation, field irrigation etc.A lot of cement pipe, steel pipes of using such as groundwater supply, draining, because cement pipe, steel pipe are the rigidity pipe, weight is big, transportation and arrangement inconvenience, and break easily, maximum PVC or similar pipeline are used in exhaust, subway ventilation, mine ventilation at present, basic is the single wall solid tubes, and the raw material consumption is big, causes the cost height, and since the big and cement pipe of weight etc. have same transportation and arrange problems such as difficulty.
Summary of the invention
At the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of aesthetic in appearance, double-wall corrugated pipe that comprehensive cost is low and easy for installation rational in infrastructure.
Described a kind of double-wall corrugated pipe is the double-deck tubing of hollow, it is characterized in that described bellows is made of outer wall with annular corrugated structure and level and smooth inwall, and at least one end of described bellows termination is provided with the enlarging of surface smoothing.
Described a kind of double-wall corrugated pipe is characterized in that the enlarging of described bellows is equipped with the internal thread that is threaded with link.
Described a kind of double-wall corrugated pipe, the outer wall that it is characterized in that described annular corrugated structure is for being the bellows of main raw material through extrusion modling with the high density polyethylene (HDPE).
Above-mentioned a kind of double-wall corrugated pipe, the double-deck tubing for hollow is used for water supply, draining, blowdown, exhaust, subway ventilation, mine ventilation, field irrigation etc.Described bellows is made of outer wall with annular corrugated structure and level and smooth inwall, and at least one end of described bellows termination is provided with the enlarging of surface smoothing, and described bellows is that main raw material makes through extrusion modling by high density polyethylene (HDPE).The double-wall corrugated pipe of the utility model by adopting above-mentioned technology to obtain two-layerly can be thin layer, like this can conservation, and not only can reduce fabricating cost, and alleviate the weight of product bellows greatly, convenient transportation is installed also laborsaving.Skin is made as annular corrugated structure, whole bellows aesthetic in appearance, and inside is made as smooth structure, and resistance is little, and flow is big, and the raw material that uses is high density polyethylene (HDPE), acid resistant alkali is anticorrosive, has prolonged the working life of bellows, has obtained liking of Consumer.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A face sectional structure schematic representation of Fig. 1.
Among the figure: 1-outer wall, 2-inwall, 3-enlarging.
Embodiment
The utility model will be further described below in conjunction with Figure of description:
Shown in Fig. 1-2, a kind of double-wall corrugated pipe, double-deck tubing for hollow, described bellows is made of outer wall 1 with annular corrugated structure and level and smooth inwall 2, at least one end of described bellows termination is provided with the enlarging 3 of surface smoothing, the enlarging 3 of described bellows is equipped with the internal thread that is threaded with link, and the outer wall of described annular corrugated structure 1 is for being the bellows of main raw material through extrusion modling with the high density polyethylene (HDPE).
Double-wall corrugated pipe described in the utility model, be used for large-scale water delivery, supply water, draining, blowdown, exhaust, subway ventilation, mine ventilation, field irrigation etc., digitizing all fronts centralized control when it is made, the two-shipper co-extrusion, enlarging once-through at random is because used main raw material high density polyethylene (HDPE) has excellent chemical stability, the performance of ageing-resistant and resisting environmental stress and cracking belongs to flexible pipe by its double-wall corrugated pipe of producing for raw material, main performance is as follows: the critical external compressive resistance ability is strong, outer wall is wave structure ringwise, has strengthened the ring stiffness of tubing greatly, thereby has strengthened the resistivity of pipeline to the soil load.The utility model is a hollow structure, and engineering cost is low, under the condition that waits load, only needs thin tube wall just can meet the demands, and therefore, manages ratio mutually with the real wall with the material specification, can save the raw material about half, greatly reduces cost of production; Because double-wall corrugated pipe is in light weight, carrying be connected all very convenient, so quick construction, maintenance work are simple.
Double-wall corrugated pipe of the present utility model, skin are made as annular corrugated structure, whole bellows aesthetic in appearance, and inside is made as smooth structure, resistance is little, and flow is big, and the raw material that uses is high density polyethylene (HDPE), acid resistant alkali is anticorrosive, has prolonged the working life of bellows, has obtained liking of Consumer.
