Abstract

The utility model relates to a double-wall PE (Polyethylene) bellow which belongs to the technical field of conveying pipeline and is used for water supplying, draining, pollution discharging, exhausting, metro ventilating, mine ventilating, field irrigation, etc. The bellow is composed of an outer pipe provided with concave and convex circular corrugations and a smooth inner pipe, wherein reinforcing ribs are arranged at the positions of the concave circular corrugations and convex circular corrugations of the outer pipe for matching, a flaring with smooth surface is arranged on the end head of at least one end of the bellow, and the bellow is made by extrusion molding by taking a high density polyethylene as a main raw material through. With the adoption of the technology, the double-wall bellow with reinforcing ribs takes the high density polyethylene as the raw material so as to be acid-base resisting and corrosion resisting; the interior of the bellow is of the smooth structure, so that the resistance is small, and the flow quantity is large; the outer layer is of the circular corrugated structure, so that the whole bellow is attractive in appearance; and the reinforcing ribs are arranged at the positions of the concave circular corrugations and convex circular corrugations for matching, so that the strength of the bellow is improved, the impact resistance of the bellow is enhanced, and the service life of the bellow is prolonged.

Description

A kind of PE double-wall corrugated pipe
Technical field
The utility model belongs to the conveyance conduit technical field, is specifically related to a kind of PE double-wall corrugated pipe of the aesthetic in appearance and band stiffening rib that intensity is high 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, owing to 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 cost high; And since the big and cement pipe of weight etc. have same transportation and arrange problems such as difficulty.
The model utility content
To the problems referred to above that exist in the existing technology, the purpose of the utility model is to provide a kind of PE double-wall corrugated pipe of the aesthetic in appearance and band stiffening rib that intensity is high rational in infrastructure.
Described a kind of PE double-wall corrugated pipe, described bellows constitutes by having concavo-convex annular corrugated outer tube and level and smooth interior pipe, it is characterized in that the hollow toroid ripple of described outer tube and bulge loop shape ripple place are equipped with stiffening rib.
Described a kind of PE double-wall corrugated pipe is characterized in that at least one end of described bellows termination is equipped with the enlarging that is used for institute's link connection.
Described a kind of PE double-wall corrugated pipe is characterized in that described stiffening rib is an arcuate structure, in the pressing process of outer tube, stiffening rib is placed in the mould, and stiffening rib is enclosed in the outer tube of polyethylene formation when the polyethylene of fusion solidifies.
Described a kind of PE double-wall corrugated pipe, it is characterized in that described outer tube for be material with the high density polyethylene (HDPE) through extrusion modling with concavo-convex annular corrugated bellows.
Described a kind of PE double-wall corrugated pipe, it is characterized in that described in pipe for being the ganoid level and smooth bellows of material through extrusion modling with the high density polyethylene (HDPE).
Above-mentioned a kind of PE double-wall corrugated pipe is used for water supply, draining, blowdown, exhaust, subway ventilation, mine ventilation, field irrigation etc.Described bellows constitutes by having concavo-convex annular corrugated outer tube and level and smooth interior pipe; The hollow toroid ripple of described outer tube and bulge loop shape ripple place are equipped with stiffening rib; At least one end of 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 utility model is through the double-wall corrugated pipe of the band stiffening rib that adopts above-mentioned technology and obtain, and the raw material that uses is high density polyethylene (HDPE), and acid resistant alkali is anticorrosive; Inside is made as smooth structure, and resistance is little, and flow is big; Skin is made as annular corrugated structure, whole bellows aesthetic in appearance, and be equipped with stiffening rib at hollow toroid ripple and bulge loop shape ripple place; Increase the brute force of bellows, strengthen impact resistance, prolonged the working life of bellows.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-outer tube, pipe in the 2-stiffening rib, 3-.
Embodiment
Below in conjunction with Figure of description the utility model is done further to describe:
As shown in Figure 1, a kind of PE double-wall corrugated pipe, described bellows constitutes with level and smooth interior pipe 3 by having concavo-convex annular corrugated outer tube 1, and the hollow toroid ripple 1b of described outer tube 1 and bulge loop shape ripple 1a place are equipped with stiffening rib 2.For with the property easy to connect of outer tube, at least one end of described bellows termination is equipped with and is used for the enlarging that institute's link connects, this enlarging inwall is provided with internal thread, with outer tube through being threaded.
The used stiffening rib 2 of the utility model is set to arcuate structure or similar structure, and is identical with the structure of hollow toroid ripple 1b and bulge loop shape ripple 1a, convenient cast.
The bellows outer tube of the utility model is annular corrugated structure, whole bellows aesthetic in appearance, and be equipped with stiffening rib at hollow toroid ripple and bulge loop shape ripple place, and increase the brute force of bellows, strengthen impact resistance, prolonged the working life of bellows.Described outer tube 1 for be material with the high density polyethylene (HDPE) through extrusion modling with concavo-convex annular corrugated bellows; In pipe 3 for being the ganoid level and smooth bellows of material through extrusion modling with the high density polyethylene (HDPE); The double-wall corrugated pipe the key technical indexes that obtains is following: ring stiffness (kg/ ㎡) SN8:>=8 impact properties (TIR)/% :≤10, and change flexibility: sample is slick and sly, no back-flexing; Crack-free, two arms do not have disengagement.The baking oven test: no steam bubble, no layering does not have division.The low-temperature impact brittle temperature/(℃)-30.
The described double-wall corrugated pipe of the utility model is used for large-scale water delivery, supplies water draining; Blowdown, exhaust, subway ventilation, mine ventilation; Field irrigation etc., digitizing all fronts centralized control when it is made, two-shipper co-extrusion, enlarging once-through at random; Because used main raw material high density polyethylene (HDPE) has the performance of excellent chemical stability, 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 following: 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 practice thrift 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.
