Abstract

The utility model discloses a steel-belt-reinforced spiral corrugated pipe which comprises a pipeline body and a spiral convex edge on the outer surface of the pipeline body. The pipeline body is a high-density polyethylene inner pipe, the spiral convex edge is formed by enabling steel belts formed by bending to equidistantly and spirally wind the pipeline body, a high-density polyethylene outer layer is covered on the periphery of the formed steel belts, the cross section of each formed steel belt is M-shaped, width of a gap between two adjacent steel belts is smaller than that of a secondary side of each steel belt, the top of each M-shaped steel belt is of a circular-arc-transition structure, and a rounding structure is arranged on the edge of a secondary side of each steel belt formed by bending. The steel-belt-reinforced spiral corrugated pipe is high in rigidity and strength, has certain flexibility and is suitable for occasions needing bending construction.

Description

Steel band reinforced spiral ripple pipe
Technical field
The utility model relates to bellows, especially relates to a kind of steel band reinforced spiral ripple pipe.
Background technique
Steel band reinforced polyethylene spiral ripple pipe is take polyethylene as internal and external layer body material, with surface coating high-performance adhering resin and take the steel band wave shape body of brake forming as main support structure, on production line, by being wound around, extrusion molding is combined into overall helical corrugation tubing.This product combines the Optimalities such as corrosion-resistant, the wear-resistant and pliability of high rigidity, high strength and the plastics of steel, not only can make tubing reach the ring stiffness of higher level, but also solved the corrosion-resistant problem of steel, the pipe-line system of steel band reinforced polyethylene spiral ripple pipe adopts the modes such as hot-melt extruded welding and electric smelting band to connect conventionally, adapt to various different engineering operating mode needs, met preferably and sealed requirement reliable and easy to connect, pipe applications has a extensive future, and is the first-selected product that substitutes at present heavy caliber tradition waste pipe.
Chinese utility model patent CN 202109107 U disclose a kind of steel band reinforced polyethylene spiral ripple pipe, comprise plastic inner pipe, in the equidistant winding of outer surface of plastic inner pipe, there is the shaped-steel strip of two sideband flangings, the flanging of two adjacent rings shaped-steel strip laminates and overlaps, between two adjacent rings shaped-steel strip, be wound with connection steel band, connect steel band pressure on the flanging of two adjacent rings shaped-steel strip.Greatly improve the bulk strength of tube wall, made between two adjacent rings shaped-steel strip not cracky seepage, expanded the application area of plastics ribbon spiral bellows.
But in the technological scheme that above-mentioned model utility provides, the flanging of two adjacent rings shaped-steel strip laminates and overlaps, and with connecting steel band pressure on the flanging of two adjacent rings shaped-steel strip.There is such deficiency: 1. the utilization ratio of pair steel band is lower, waste steel; 2. pipeline body outer surface is covered by steel band entirely, causes body rigidity too large, and orthostatic is too strong, is not suitable for pipe-line system and has bending occasion.
For the deficiency of prior art scheme, inventor of the present utility model has proposed a kind of new steel band reinforced spiral ripple pipe.
Model utility content
The utility model provides a kind of steel band reinforced spiral ripple pipe, keeping the steel band reinforced spiral ripple pipe Gao Gang high-intensity while of Du ﹑ to waste steel in solving prior art scheme and not to be suitable for pipe-line system the problem with bending occasion.
The technical problem that the utility model solves realizes by the following technical solutions.
Steel band reinforced spiral ripple pipe described in the utility model, comprise the spiral ridge of pipeline body and pipeline body outer surface, described pipeline body is high density polyethylene (HDPE) inner tube, described spiral ridge is comprised of the equidistant spiral surrounding pipeline body of steel band of brake forming, and the periphery of shaped-steel strip is coated with high density polyethylene (HDPE) skin.The cross section of described shaped-steel strip is M type structure, and the gap width between adjacent two steel bands is less than the secondary width of steel band.
Further, the steel band top of described brake forming adopts arc transition structure.
Further, the secondary edge of the steel band of described brake forming has rounded feature.
This advantage is:
(a). the cross section of steel band adopts M type, and compared with the U-shaped design adopting with traditional scheme, Rigidity and strength is higher.
(b). between adjacent two steel bands, have gap in vain, and clearance distance is less than the secondary width of steel band, this structure does not affect the bulk strength of bellows, and body can carry out suitable bending construction according to the needs of certain applications simultaneously.
(c). the secondary of steel band adopts rounded feature, can prevent body in BENDING PROCESS due to steel band secondary with sharp edges embed polyethylene pipe body, and the body premature aging causing, the problem such as damaged.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is steel band reinforced spiral ripple pipe structural representation described in the utility model.
Fig. 2 is steel band reinforced spiral ripple pipe A part partial enlarged drawing.
In figure, 1. pipeline body, 2. spiral ridge, 3. steel band, 4. high density polyethylene (HDPE) skin, 5. secondary.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1, the steel band reinforced spiral ripple pipe that the utility model provides, comprise the spiral ridge 2 of pipeline body 1 and pipeline body 1 outer surface, pipeline body 1 is high density polyethylene (HDPE) inner tube, spiral ridge 2 is comprised of the equidistant spiral surrounding pipeline body of steel band 3 of brake forming, and the periphery of steel band 3 is coated with high density polyethylene (HDPE) skin 4.The cross section of steel band 3 is M type structure, with traditional scheme adopt U-shaped design compared with, the shaped-steel strip Rigidity and strength of this M type structure is higher.3 of adjacent two shaped-steel strips are gapped, and the width in gap is less than the width of the secondary 5 of shaped-steel strip 3, and this structure does not affect the bulk strength of bellows, and body can carry out suitable bending construction according to the needs of certain applications simultaneously.
Steel band 3 tops of brake forming adopt arc transition structure.
The edge of the secondary 5 of the steel band 3 of brake forming has rounded feature.Can prevent body in BENDING PROCESS due to steel band secondary with sharp edges embed polyethylene pipe body, and the body premature aging causing, the problem such as damaged.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
