Abstract

The utility model relates to a wear-resistant eccentric pipe, which belongs to a slurry transporting pipe. The center point of the outer surface of the pipe and the center point of an inner surface are not positioned at the same position; under the situation that coequal materials are used and a working pressure is allowed, one side wall of the pipe is thickened, while the other side wall is thinned. The section of the pipe takes an eccentric round shape. When in use, the side with a thick wall is taken as a bottom, which can increase the wear life of the pipe bottom, thus improving the life service of the pipe, and having convenient use without increasing cost. The wear-resistant eccentric pipe of the utility model has the advantages of simple structure, convenient use, improving the life service of the pipe without increasing production cost at the same time, and moreover, effectively avoiding a plurality of costs brought by the traditional mode of rotating the pipe, and having strong practicality.

Description

Wear-resisting eccentric tubing

Technical field

The utility model relates to slurry and carries tubing, particularly a kind of wear-resisting eccentric tubing.

Background technique

As everyone knows, slurry is carried with the pipe applications environment more abominable.As shown in Figure 1, at present, domestic slurry is carried tubing, adopts various high-abrasive material pipes usually, and its structure is generally the uniform circular pipe of wall thickness.

In the course of conveying of slurry, slurry has certain wearing and tearing to tubing, and the bottom is more and more thinner in use for some time to cause tubing; In order to save cost, can rotate tubing usually, will be transferred to the top by the bottom of wear down, and original top transfers bottom continuation use to.Like this, though increased the working life of tubing to a certain extent, complicated operation must dig tubing from the ground and block and could rotate at soldering point, and not only construction is inconvenient, and increases cost, influences ordinary production, need be improved.

Summary of the invention

The purpose of this utility model is to provide a kind of wear-resisting eccentric tubing, solved tubing commonly used working life short, cost is high and rotate the tubing troublesome poeration, problems such as construction inconvenience.

The technical solution of the utility model is: the central point of pipe outer surface and the central point of internal surface under the situation of using equivalent material, working pressure to allow, make a side thickness of tubing not at same position, and another sidewall is thin.The cross section of this tubing is eccentric circular.During use, a side of wall thickness as the bottom, can be increased the wear-resisting time of tubing bottom, thereby improve the working life of tubing, easy to use and can not increase cost.

Advantage of the present utility model is: simple in structure, easy to use, when not increasing cost of production, improved the working life of tubing, and many costs of effectively having avoided the mode of traditional rotation tubing to bring, practical.

Description of drawings:

The schematic cross-section of Fig. 1 tubing commonly used;

Fig. 2 is the schematic cross-section of the utility model tubing.

Embodiment:

As shown in Figure 2, the cross section of the wear-resisting eccentric tubing 1 of the utility model is eccentric circular, and the center of circle of the center of circle of its outer surface 2 and internal surface 3 is not at same position, under the situation of using equivalent material, working pressure to allow, make a side thickness of tubing 1, another sidewall is thin.During use, a side of wall thickness as the bottom, can be increased the wear-resisting time of tubing 1 bottom, thereby improve the working life of tubing 1, easy to use and can not increase cost.The inconvenience of also effectively having avoided simultaneously traditional rotation slurry to carry the mode of tubing to bring.

Claims

1, a kind of wear-resisting eccentric tubing is characterized in that: this tubing (1) is that the central point of the central point of outer surface (2) and internal surface (3) is not at the eccentric pipe of same position.

2, wear-resisting eccentric tubing according to claim 1 is characterized in that: the cross section of described tubing (1) is for circular.
