Quick manufacturing method of anti-corrosion compound pipeline

Abstract

The invention relates to a quick manufacture method of an anti-corrosion compound pipeline. The quick manufacture method can be used for effectively solving the problem of manufacturing the anti-corrosion compound pipeline at high efficiency and low cost. The technical scheme adopted by the invention comprises the following steps of: presetting an alloyed powder body bonded with a binder at the inner wall of a metal pipeline which rotates at a high speed, adjusting the electromagnetic induction frequency by virtue of an electromagnetic induction heating method, and controlling the heating depth and the heating time, so that the alloyed powder body can not be completely fused to be slightly fused with the surface layer of the inner wall of the pipeline; enabling a heating device to move along the axis relative to the rotating pipeline, and solidifying the fused alloy and surface-layer base body metal, which depart from a heating region to produce metallurgical bonding and form an anti-corrosion alloy layer with flat and beautiful surface and high bonding strength, so that an anti-corrosion compound pipeline can be manufactured. The manufacturing method comprises the following steps of: preparing water glass and alloy powder paste; fixing the pipeline to be machined onto a power head; coating the alloy powder paste; drying; biting in a fusing way; and cooling to obtain the anti-corrosion compound pipeline. The quick manufacturing method is simple, easy to operate, high in production efficiency, good in product quality, and long in service life.

Description

technical field [0001] The invention relates to pipeline production, in particular to a rapid manufacturing method of an anti-corrosion composite pipeline. Background technique [0002] In the dense medium coal preparation system, suspensions with high hardness, sharp particles, and strong abrasiveness, as well as hard materials such as coal gangue and medium coal, will cause serious abrasion to the pipeline. The service life of general metal pipes is very short, about several From one month to one year, it is necessary to frequently replace pipes and parts, which directly causes waste of man-hours, materials, mineral resources, etc., thereby reducing production efficiency and increasing production costs.

[0002] In the dense medium coal preparation system, suspensions with high hardness, sharp particles, and strong abrasiveness, as well as hard materials such as coal gangue and medium coal, will cause serious abrasion to the pipeline. The service life of general metal pipes is very short, about several From one month to one year, it is necessary to frequently replace pipes and parts, which directly causes waste of man-hours, materials, mineral resources, etc., thereby reducing production efficiency and increasing production costs

In response to this problem, a variety of techniques have emerged in recent years to improve the abrasion resistance of pipelines, such as cast stone pipeline composite technology, ultra-high molecular weight polyethylene composite technology, hard surface surfacing composite technology, thermal spraying technology, etc., although these processes To a certain extent, the anti-abrasion ability of the inner wall of the pipeline is improved, but there are still problems such as long production cycle, complicated process, high cost, and low bonding strength between the anti-abrasion layer and the substrate.

Therefore, there is no high-efficiency, low-cost, reliable and durable corrosion-resistant composite pipe production method at present.
