Large pipeline structure

Abstract

The invention discloses a large pipeline structure. The large pipeline structure comprises a pipeline body, wherein the pipeline body is formed by splicing at least two metal plates, each metal platecomprises a first panel, a second panel and a plurality of hollow pipes arranged between the first panel and the second panel, connecting layers are arranged between the hollow pipes and the first panels and between the hollow pipes and the second panels, and flanges are arranged at least one ends of the hollow pipes. The large pipeline structure has the advantages of light dead weight, high strength, stable structure, sound insulation as well as noise reduction, heat preservation, high temperature resistance, vibration resistance, long service life and the like; and the pipeline body of the large pipeline structure can be a gas delivery pipeline, an oil delivery pipeline, a water supply and drainage pipeline, a vacuum transportation pipeline and the like.

Description

technical field [0001] The invention relates to a pipeline structure, especially a large pipeline structure. Background technique [0002] Existing pipeline materials mainly include steel pipes (such as welded steel pipes, seamless steel pipes), cast iron pipes (such as gray pipes, ductile iron pipes), concrete pipes, plastic pipes and composite pipes, etc. However, these pipes need to be processed through their outer walls. In order to have certain anti-corrosion, moisture-proof, anti-seepage and other properties. [0003] In addition, the above-mentioned pipelines all have certain defects. First, steel pipes, cast iron pipes and concrete pipes are heavy, especially large pipes, which are time-consuming and labor-intensive; second, the production cycle is long; third, the compression resistance is poor; fourth, the insulation effect is poor; Fifth, poor vibration resistance; sixth, poor heat preservation effect. [0004] There are also pipes made of honeycomb panels. The...

Problems solved by technology

However, the honeycomb core is connected into one body through multiple honeycomb structures, and the upper and lower ends of the honeycomb core are in line contact with the upper and lower panels. During the brazing process, the welding between the honeycomb core and the upper and lower panels will be weak, and gaps will easily occur. Or voids, etc., which will lead to instability of the overall structure, low strength, poor impact resistance, etc.
