Abstract

The invention discloses a wear-resisting and scour-resisting pipeline and a production method thereof, and belongs to special pipelines in the field of pipeline transportation. A rubber lining is arranged in the pipeline, a framework of the rubber lining is made of aramid glass fibers and polyamide fabrics, special anti-corrosion rubber is used as a base material to be mixed with the rubber lining, and highly wear-resisting materials such as carborundum micro powder or zirconium carbide micro power, alumina micro powder, monox micro powder and monatomic silicon micro powder are supplementally used for filling during mixing, so that the strength, wear resistance, scour resistance and puncture resistance of the rubber lining are improved to the greatest extent, the rubber lining is enabled to have not only a certain strength, wear resistance, scour resistance and puncture resistance but also a certain rebound resilience and flexibility, and service life of the pipeline is prolonged substantially.

Description

technical field [0001] The invention relates to a special pipeline in the pipeline transportation field, in particular to a wear-resistant and scour-resistant pipeline and a manufacturing method thereof. Background technique [0002] Pipeline transportation is a common transportation method in the industrial field. Commonly used pipelines are generally made of metal or cast in cement concrete. When transporting corrosive liquids or low-concentration mortars, the inner wall of the pipeline will be washed and corroded for a long time. , friction will cause its service life to be greatly reduced. Therefore, in order to improve its service life, linings are often installed in the pipeline. These lining materials are generally alloys, cement pouring layers or polymer material layers, but they are not very good. Solve the problem of low service life. [0003] Rubber is an elastic polymer that can be obtained from the sap of some plants (natural rubber) or man-made (synthetic rubb...
