Description

MPP power pipe

Technical field

The utility model belongs to electric power tubing technical field, particularly relates to a kind of MPP power pipe.

Background technology

Power cable tubing in existing market has PE and MPP two type; MPP power pipe is compared with PE electric power tubing; because the fusing point of MPP material is relatively high; the Young's modulus of material is bigger; wearing coefficient is higher; therefore MPP tubing has good resistance to elevated temperatures; product physical and mechanical property is better relative to PE; the use of high pressure-temperature power cable protecting pipe material can be suitable for; therefore the high-tension electricity protection tubing applied on market is modified polypropene (MPP) tubing substantially, but also there is the shortcoming such as insufficient strength, compressive property difference in MPP tubing.

Practical novel content

The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of MPP power pipe, for solving the shortcoming such as MPP power pipe insufficient strength, compressive property difference.

For achieving the above object and other relevant objects, the utility model provides a kind of MPP power pipe, it is interconnected by some pipe bodies, it is outer that the tube wall of described pipe body comprises modified polypropene internal layer, middle reinforcement layer and modified polypropene, described modified polypropene internal layer and modified polypropene skin adopt the mode of co-extrusion to be formed on the interior outer side of middle reinforcement layer, it is outer that described middle reinforcement layer comprises glass internal layer, steel wire mesh frame and glass, and described glass internal layer and glass skin adopt the mode of co-extrusion to be formed on the interior outer side of steel wire mesh frame.

Preferably, electrical fusion joint is adopted to connect between described pipe body.

Preferably, the length of described pipe body is 6m ~ 13m.

Preferably, the external diameter of described pipe body is 110mm-250mm, and wall thickness is 5mm-18mm.

As mentioned above, it is necessary, MPP power pipe of the present utility model, there is following useful effect:

1, the utility model is using modified polypropene outer field main raw material in tubing, polypropylene material makes tubing have enough intensity and toughness, good erosion resistance and heat resistance through modified, simultaneously, middle reinforcement layer is added between modified polypropene internal layer and modified polypropene skin, it is outer that middle reinforcement layer comprises glass internal layer, steel wire mesh frame and glass, therefore the advantage of woven wire and glass fiber material can be made full use of, improve the physical and mechanical property of tubing, strengthen the survivability of tubing in installation and use procedure.

2, the steel wire diameter of steel wire mesh frame and glass internal layer and the outer field thickness of glass can be adjusted to improve the physical and mechanical property of tubing, meet different construction needs.

Accompanying drawing explanation

Fig. 1 is shown as the schematic diagram of the utility model MPP power pipe.

Fig. 2 is shown as the part sectioned view of the utility model pipe body.

Element numbers explanation

1 pipe body; 2 electrical fusion joints; 11 modified polypropene internal layers; 12 glass internal layers; 13 steel wire mesh frames; 14 glasses are outer; 15 modified polypropenes are outer.

Embodiment

By particular specific embodiment, enforcement mode of the present utility model being described below, person skilled in the art scholar the content disclosed by this specification sheets can understand other advantages of the present utility model and effect easily.

As depicted in figs. 1 and 2, the utility model provides a kind of MPP power pipe, it is interconnected by some pipe bodies 1, the tube wall of pipe body 1 comprises modified polypropene internal layer 11, middle reinforcement layer and modified polypropene skin 15, the mode of modified polypropene internal layer 11 and the outer 15 employing co-extrusions of modified polypropene is formed on the interior outer side of middle reinforcement layer, middle reinforcement layer comprises glass internal layer 12, steel wire mesh frame 13 and glass skin 14, and the mode of glass internal layer 12 and the outer 14 employing co-extrusions of glass is formed on the interior outer side of steel wire mesh frame 13. The utility model is using modified polypropene outer field main raw material in tubing, polypropylene material makes tubing have enough intensity and toughness, good erosion resistance and heat resistance through modified, simultaneously, middle reinforcement layer is added between modified polypropene internal layer 11 and modified polypropene skin 15, middle reinforcement layer comprises glass internal layer 12, steel wire mesh frame 13 and glass skin 14, therefore the advantage of woven wire and glass fiber material can be made full use of, improve the physical and mechanical property of tubing, strengthen the survivability of tubing in installation and use procedure; In addition, it is also possible to the adjustment steel wire diameter of steel wire mesh frame and glass internal layer and the outer field thickness of glass improve the physical and mechanical property of tubing, meet different construction needs.

Usually, the mode of connection of MPP power pipe adopts welding machine thermofussion welding docking, but soldering opening is not good, can damage cable maybe may draw flat, therefore electrical fusion joint 2 is adopted to connect between pipe body 1 of the present utility model, by making it heat the nichrome wire energising being embedded in electric smelting pipe internal surface, thus the internal surface of connecting tube and the outside surface of tubing are melted respectively, the object of welding is reached after being cooled to want seeking time, adopting mode strength of joint and the sealing effect of electric melting connection very good, the tubing obtained after connection anti-axial tension ability is strong.

If client's quantity requires big, in order to reduce costs (freight charges and welding expense), the length of pipe body 1 is 6m ~ 13m.

In order to meet different construction needs, MPP power pipe is divided into common excavation type and strengthens no-dig technique type, and regular size model is see table 1 and table 2.

The common excavation type of table 1-(unit: mm)
