Be arranged on steel pipe inner wall and with the vertically disposed screens annular groove of screens groove, the superhigh molecular weight polyethylene pipe
The screens rib and screens annulus being equipped with screens groove and screens annular groove are provided with lateral wall.
Preferably, the free box flange component element includes being arranged on the baffle ring of S type steel pipe ends and is arranged on S types
On steel pipe and the lap joint flange that can slide.
Preferably, the screens groove is semicircle column type screens groove.
Compared with prior art, it is the advantages of the utility model with good effect,
1st, the utility model lined with ultra-high molecular weight polythene material, high abrasion, corrosion-resistant, pressure-bearing is high, both solves steel
The not wear-resisting requirement of pipe itself, and solve the relatively low requirement of pressure-bearing of superhigh molecular weight polyethylene pipe road itself, solve at the same time
The requirement of multiple elbow assembling process, realizes the target call of high quality and low cost compared with other elbows；
2nd, its screens groove, screens annular groove, screens rib and screens annulus are equipped with, and substantially increase super high molecular weight
The connection effect of polyethylene pipe and S type steel pipelines, improves the service life and using effect of the utility model.
Brief description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment
The attached drawing used is briefly described, it should be apparent that, drawings in the following description are some embodiments of the utility model,
For those of ordinary skill in the art, without having to pay creative labor, can also be obtained according to these attached drawings
Obtain other attached drawings.
Fig. 1 is the structure diagram that the lined with ultra-high molecular weight polyethylene pipe profile iron that embodiment 1 provides moulds composite-curve；
More than in each figure, 1, steel pipe；2nd, superhigh molecular weight polyethylene pipe；3rd, lap joint flange；4th, baffle ring.
Embodiment
It is below in conjunction with the accompanying drawings and real in order to be more clearly understood that the above-mentioned purpose of the utility model, feature and advantage
Example is applied to be described further the utility model.It should be noted that in the case where there is no conflict, embodiments herein and reality
Applying the feature in example can be mutually combined.
Many details are elaborated in the following description in order to fully understand the utility model, still, this practicality
New to implement using different from other modes described here, therefore, the utility model is not limited to be described below
The limitation of the specific embodiment of specification.
Embodiment 1, as shown in Figure 1, the utility model provides a kind of lined with ultra-high molecular weight polyethylene pipe profile iron modeling
Composite-curve, including S type steel pipelines, which is then that steel pipe has been designed to S types for demand, its S
The effect of type steel pipeline has at 2 points, when outer wrapping, second, playing pipeline integral support；It is not difficult to find out from figure, inventor
In order to improve the using effect of the utility model, therefore ultra-high molecular weight polyethylene is provided with S type steel pipeline internal side walls
Pipe, adds the designing scheme of superhigh molecular weight polyethylene pipe in S type steel pipelines, can the utility model significantly use
Service life, for superhigh molecular weight polyethylene pipe, be by ethene, divinylic monomer under the action of catalyst, be polymerized
Average molecular weight be more than 2,000,000 thermoplastic engineering plastic.The material comprehensive performance can be for a long time under the conditions of -269 to+80 DEG C
Work, is referred to as the engineering plastics of " surprising ", and ultra-high molecular weight polyethylene engineering plastics (UHMW---PE) pipe technology exists
China is increasingly ripe, and more and more engineerings employ this pipeline, becomes a kind of new thermoplastic of moderate function admirable
