Abstract
The utility model discloses an abrasion-resistant concrete pump pipe which comprises an inner pipe and an outer pipe. Both the inner pipe and the outer pipe are manganese steel welded pipes. An outer pipe wall of the inner pipe is tightly fitted with an inner pipe wall of the outer pipe through a compound technology. A 65# manganese steel welded pipe is adopted by the inner pipe. A 16# manganese steel welded pipe is adopted by the outer pipe. The abrasion-resistant concrete pump pipe is composited by a two-layer welded pipe. Compared with the traditional seamless steel tubes, the abrasion-resistant concrete pump pipe is capable of saving cost, meanwhile, the inner pipe is rubbed with moving concretes, the 65# manganese steel welded pipe which is good in abrasion resistance is adopted, and abrasion-resistant performances of a whole pump pipe is greatly improved, and service life of the pump pipe is improved.
Description
Technical field
The utility model relates to a kind of flowing medium conveyance conduit, relates in particular to a kind of abrasion-proof concrete pump line for the concrete pump delivering concrete.
Background technique
At present, existing concrete pump conveyance conduit, namely pump line, be all to adopt the seamless steel pipe of high tenacity to manufacture, and has following shortcoming:
1) the seamless steel pipe price is higher, causes the holistic cost of pump line higher;
2) hardness of seamless steel tube is low, in use exists inner tube wall surface friction drag large, and quick abrasion needs the damaged pump line of frequent transposing, makes the operation overall cost occupy high.
The model utility content
The purpose of this utility model is to provide a kind of abrasion-proof concrete pump line, and it has the characteristics of the low and high-wear resistance of cost; Have to solve traditional concrete pump pipe that cost is high, the problem of quick abrasion.
For reaching this purpose, the utility model by the following technical solutions:
A kind of abrasion-proof concrete pump line, it comprises inner and outer pipe, and wherein, described inner and outer pipe is the manganese steel welded tube, and the outer tube wall of described inner tube and the inner tubal wall of outer tube fit tightly.
Especially, described inner tube adopts 65# manganese steel welded tube, and described outer tube adopts 16# manganese steel welded tube.
Especially, described inner and outer pipe adopts metal composite to fit tightly, and to prevent the loosening impact to whole pump line of inner and outer pipe, also butt welded seam carries out good protective action simultaneously.
Especially, the junction at described inner and outer pipe two end part is adopted and is welded to connect.
The beneficial effects of the utility model are, compared with prior art described abrasion-proof concrete pump line adopts double-deck welded tube to be composited, with respect to traditional seamless steel pipe, saved cost, simultaneously because of inner tube and the concrete friction of flowing, therefore adopt more wear-resisting 65# manganese steel welded tube, greatly improved the wear-resisting property of whole pump line, the working life of having improved pump line.

Embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
See also shown in Figure 1ly, Fig. 1 is the sectional drawing of the abrasion-proof concrete pump line that provides of the utility model embodiment 1.
In the present embodiment, a kind of abrasion-proof concrete pump line comprises inner tube 1 and outer tube 2, and described inner tube 1 adopts 65# manganese steel welded tube, described outer tube 2 adopts 16# manganese steel welded tube, described inner tube 1 adopts more wear-resisting 65# manganese steel welded tube, can improve the wear-resisting property of pump line integral body, improves the working life of pump line.Simultaneously described inner tube 1 and outer tube 2 adopt metal composite to fit tightly, and the junction at described inner tube 1 and outer tube 2 two end part is adopted and is welded to connect.To prevent inner tube 1 and the loosening impact to whole pump line of outer tube 2, also butt welded seam carries out good protective action simultaneously.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
