Embodiment Construction

[0018] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] Such as figure 1 As shown, the embodiment of the present invention provides a method for manufacturing a mud conveying pipe. The manufacturing method for the mud conveying pipe includes: first selecting steel pipe materials according to the needs of mud conveying, including the length, inner diameter and outer diameter of the blank, and then selecting At least one end of the steel pipe material is roughened, and the end is formed into a flange structure through the roughening treatment.

[0020] In this embodiment, the end of the steel pipe material is roughened so that the end forms a flange structure, so that the mud delivery pipe and the flange at the end are integrally structured, a...

Abstract

The invention provides a slurry transporting pipe manufacturing method and a slurry transporting pipe. The slurry transporting pipe manufacturing method comprises the steps of selecting a steel pipe material and conducting roughening treatment on at least one end of the steel pipe material so that at least one end of the steel pipe material forms a flange structure. Through the manufacturing method, the problems that the manual and material cost of the transporting pipe in the prior art is high and the service life is short can be solved.

Description

technical field [0001] The invention relates to the construction field, in particular to a method for manufacturing a mud delivery pipe and the mud delivery pipe. Background technique [0002] At present, when pouring cement at a building construction site, it is necessary to transport cement through a delivery pipeline. In the prior art, flanges are welded on the outer walls of the two ends of the pipeline to connect two adjacent pipelines, and wear-resistant sleeves are inlaid on the inner walls of the two ends of the pipeline to reduce the impact of cement slurry on the two ends of the pipeline. Wear at the joints of the delivery piping. [0003] In the prior art, when processing the conveying pipeline, it is necessary to carry out processes such as inner turning, outer turning, heat treatment, welding, and inlaying of steel pipes and prepare a large number of molds and pipe fittings, which requires high labor and material costs , and because the flange is welded on the...
