Compared with the prior art, the utility model has the advantages that: the pipeline pipe fitting that can use in the concrete transportation for a long time, not frequent change maintenance, and use cost is cheap.
Description
Technical Field
The utility model relates to the technical field of pipelines, in particular to a high-temperature-resistant, corrosion-resistant and wear-resistant concrete pump pipeline pipe fitting.
Background
With the continuous improvement of the requirements of China on the construction quality and progress standard of buildings and the continuous development of commercial concrete, the concrete pump truck and the concrete pump can simultaneously complete the on-site concrete conveying and distributing operation at one time, and have the characteristics of good pumping performance, wide distributing range, automatic walking, flexibility, convenience in transfer and the like. When foundation and low-rise construction and construction sites needing frequent transfer are carried out, the concrete boom pump truck and the concrete ground pump are more and more paid attention by the market and favored by users. However, concrete pump trucks and concrete pumps have the disadvantage of wearing pipe fittings, and the rapid flow of concrete during concrete delivery causes severe wear to the pipe walls. The pipeline pipe fitting is replaced frequently, and the use cost is increased, so that the high-temperature-resistant, corrosion-resistant and wear-resistant pipeline pipe fitting needs to be researched urgently.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the technical defects and provide a high-temperature-resistant, corrosion-resistant and wear-resistant concrete pump pipeline pipe fitting which can be used for a long time in concrete conveying, is not frequently replaced and maintained and has low use cost.
In order to solve the technical problems, the technical scheme provided by the utility model is as follows: the utility model provides a wear-resisting concrete pump pipeline pipe fitting of high temperature resistant corrosion-resistant, includes steel pipe and carbide wearing layer, the carbide wearing layer set up at the steel pipe inner wall, steel pipe and carbide wearing layer between be connected through the anchor coat, steel pipe tip an organic whole be connected with connecting device.
Furthermore, the connecting device comprises three forms of a rubber sealing retainer ring, a positioning sleeve and a flange.
Furthermore, the surface of the carbide wear-resistant layer is provided with an anti-corrosion layer.
Furthermore, the steel pipe comprises four forms of a straight pipe, a bent pipe or an elbow, a three-way pipe and a reducing pipe.
Compared with the prior art, the utility model has the advantages that: the utility model adopts a mode of compounding steel and carbide, so that the steel-carbide composite material has the advantages of both steel and carbide, and has the advantages of high pressure-bearing capacity, high temperature resistance, corrosion resistance, good self-lubricating property and high hardness.
