Description
Technical field
The utility model relates to a kind of composite pipe, more particularly, and particularly a kind of polyethylene wearproof composite tube with steel tightened liner.
Background technique
At present, in oil, chemical industry, electric power, metallurgy, colliery and paper industry, substantially all adopt steel pipe to carry various material, as: pulverized fuel ash, granular ore, coal, grain and various material.But due to shortcomings such as steel pipe is not corrosion-resistant, not wear-resistant, easy corrosions, make can not get effective raising the working life of steel pipe.In use for some time, namely need to change steel pipe, which results in the increase of cost of production.Therefore, be necessary to improve existing steel-pipe construction.
Model utility content
The purpose of this utility model is to provide a kind of wear-resisting, corrosion-resistant, withstand voltage and low temperature resistant polyethylene wearproof composite tube with steel tightened liner.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of polyethylene wearproof composite tube with steel tightened liner, comprise steel pipe and polyethylene wear-resistant pipe, the inner side of described steel pipe is provided with multiple groove uniformly along the length direction of steel pipe, the outside of described polyethylene wear-resistant pipe is provided with multiple projection, described projection and fit depressions uniformly along the length direction of polyethylene wear-resistant pipe.
Preferably, the groove of described groove to be cross section be arc, the projection of described projection to be cross section be arc.
Preferably, the external diameter of described polyethylene wear-resistant pipe is greater than the internal diameter of steel pipe, and described polyethylene wear-resistant pipe is by being installed in steel pipe after size reducing machine undergauge.
Compared with prior art, the utility model has the advantage of: the utility model adopts steel pipe and polyethylene wear-resistant pipe to coordinate on the one hand and forms wear-resistant composite tubes, composite pipe is made to have the performance such as corrosion-resistant, wear-resisting, withstand voltage and low temperature resistant preferably, adopt cooperation that is protruding and groove on the other hand, steel pipe and polyethylene wear-resistant pipe can be made not to produce rotation after engagement, ensure that the stability of wear-resistant composite tubes.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural drawing of polyethylene wearproof composite tube with steel tightened liner described in the utility model.
Fig. 2 is the end view drawing of polyethylene wearproof composite tube with steel tightened liner described in the utility model.
Description of reference numerals: 1, steel pipe, 2, polyethylene wear-resistant pipe, 3, groove, 4, protruding.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1, the utility model provides a kind of polyethylene wearproof composite tube with steel tightened liner, comprise steel pipe 1 and polyethylene wear-resistant pipe 2, wherein, the inner side of steel pipe 1 is provided with multiple groove 3 uniformly along the length direction of steel pipe 1, the outside of polyethylene wear-resistant pipe 2 is provided with multiple protruding 4 uniformly along the length direction of polyethylene wear-resistant pipe 2, and each protruding 4 match with corresponding groove 3.
Design principle of the present utility model is: adopt steel pipe 1 and polyethylene wear-resistant pipe 2 to coordinate on the one hand and form wear-resistant composite tubes, composite pipe is made to have the performance such as corrosion-resistant, wear-resisting, withstand voltage and low temperature resistant preferably, adopt the cooperation of protruding 4 and groove 3 on the other hand, steel pipe 1 and polyethylene wear-resistant pipe 2 can be made not to produce rotation after engagement, ensure that the stability in use of wear-resistant composite tubes.
In the utility model, described groove 3 for cross section be the groove of arc, described projection 4 for cross section be the projection of arc.And the external diameter of described polyethylene wear-resistant pipe 2 is greater than the internal diameter of steel pipe 1, described polyethylene wear-resistant pipe 2 is by being installed in steel pipe 1 after size reducing machine undergauge.
Following table 1 is the dimensioned drawing of polyethylene wearproof composite tube with steel tightened liner of the present utility model.
Table 1 (unit mm)
For example the processing of bright polyethylene wearproof composite tube with steel tightened liner and manufacture process below:
Example 1: get a long 10m, diameter is the tubing 1 of 114mm, be horizontally fixed on a frock clamping, take out a long 10m again, diameter is the polyethylene wear-resistant pipe 2 of 120mm, lain in a horizontal plane on a size reducing machine, make the axis of polyethylene wear-resistant pipe 2 and the axis collinear of tubing 1 simultaneously, and the size reducing machine for placing polyethylene wear-resistant pipe 2 can realize horizontally moving functions (as being arranged on slide block device), first size reducing machine is started by the reduced of polyethylene wear-resistant pipe 2 to 100mm, then insert in tubing 1, and alignment bumps 4 and groove 3 when inserting.Upon full insertion, whole composite pipe is placed in stove and returns footpath, namely maintain the temperature between 85-95 DEG C, continue 2 hours.
Example 2: get a long 15m, diameter is the tubing 1 of 180mm, be horizontally fixed on a frock clamping, take out a long 15m again, diameter is the polyethylene wear-resistant pipe 2 of 187mm, lain in a horizontal plane on a size reducing machine, make the axis of polyethylene wear-resistant pipe 2 and the axis collinear of tubing 1 simultaneously, and the size reducing machine for placing polyethylene wear-resistant pipe 2 can realize horizontally moving functions (as being arranged on slide block device), first size reducing machine is started by the reduced of polyethylene wear-resistant pipe 2 to 170mm, then insert in tubing 1, and alignment bumps 4 and groove 3 when inserting.Upon full insertion, whole composite pipe is placed in stove and returns footpath, namely maintain the temperature between 85-95 DEG C, continue 2 hours.
Although describe mode of execution of the present utility model by reference to the accompanying drawings; but patent owner can make various distortion or amendment within the scope of the appended claims; as long as be no more than the protection domain described by claim of the present utility model, all should within protection domain of the present utility model.
