Abstract

The invention discloses a composite conveying pipeline. The composite conveying pipeline comprises an outer pipe and an inner pipe, wherein the inner pipe is arranged in a hollow cavity in the outer pipe in a suspended mode; a first sealing cover is arranged on one side of the outer pipe; a second sealing cover is arranged on the other side of the outer pipe; the first sealing cover and the second sealing cover seal two sides of the whole outer pipe; an inner conveying channel is arranged in the middle of the inner pipe; a first assembling convex part is arranged at the end part of the inner side of the first sealing cover; a second assembling convex part is arranged at the end part of the inner side of the second sealing cover; the first assembling convex part and the second assembling convex part seal the whole inner conveying channel; one or more sealing devices are arranged in the inner conveying channel at equal distances; and a soft section is arranged in the middle of the first assembling convex part. The composite conveying pipeline is particularly suitable for conveying fluid products such as petroleum, crude oil can be filtered, the fluidity of the crude oil can be guaranteed, and if the middle of a pipeline is cut off, oil leakage does not occur, the rapid blocking can be realized, and the waste of resources is reduced.

Description

technical field

[0001] The invention relates to a pipeline, in particular to a composite conveying pipeline. Background technique

[0002] Pipelines are commonly used transport parts for liquids and gases, but the structure of pipelines is generally relatively simple. At present, pipelines for transporting oil are easy to solidify due to oil pre-cooling, and the fluidity becomes poor. Therefore, a certain amount of heat and pressure must be applied to transport. In addition There are a lot of particles in the oil, which need to be pre-filtered, and after the pipeline is cut off by external force, it is easy to cause a large amount of material transported inside, causing serious economic losses. These are some shortcomings of the current pipeline. Contents of the invention

[0003] The technical problem to be solved by the present invention is a composite conveying pipeline, which adopts a brand-new structure and can effectively solve many deficiencies in the prior art. ...
