Wear-resistant steel wire mesh pipe butt welding pipe fitting

Abstract

The invention discloses a wear-resistant steel wire mesh pipe butt welding pipe fitting. The device is formed by welding and communicating a plurality of steel wire mesh short pipes. Each steel wire mesh short pipe comprises a pipeline-level polyethylene inner layer, a pipeline-level polyethylene outer layer and a steel wire mesh reinforcing layer clamped between the inner layer and the outer layer. Wear-resistant layers are arranged on the inner walls of the pipeline-level polyethylene inner layers. Each pipeline-level polyethylene inner layer is provided with a welding end for butt welding.An annular groove is formed in the end surface of each welding end. Each annular groove coincides with the center line of a pipeline-level polyethylene inner layer. According to the invention, in a butt welding flanging process, polyethylene materials of the pipeline-level polyethylene inner layers are prevented from overflowing; in a butt welding process, the extruded polyethylene materials of the pipeline-level polyethylene outer layers can enter the annular grooves, meanwhile, the wear-resistant layers are welded into a continuous whole; and the wear-resistant steel wire mesh pipe butt welding pipe fitting is suitable for the technical field of steel wire mesh pipe welding.

Description

technical field [0001] The invention belongs to the technical field of steel wire mesh pipe welding, and in particular relates to a wear-resistant steel wire mesh pipe butt welding pipe fitting. Background technique [0002] Steel wire mesh pipe has excellent corrosion resistance and pressure bearing capacity, and has many applications in water supply, chemical industry and other fields. A highly wear-resistant modified polyolefin pipeline material is prepared by grafting PE, fillers, lubricants and processing aids, and at the same time provides a preparation method for the high wear-resistant modified polyolefin pipeline material. Wear-resistant steel wire mesh pipes are obtained by this method, and have been applied in the fields of tailings and mortar transportation. In engineering applications, due to the particularity of the structure of steel wire mesh pipe fittings, the existing pipe fittings are mostly made of steel-lined wear-resistant materials. Steel mesh pipe fit...
