Pipeline conveying equipment, consumable pressure conveying pipe and manufacturing method thereof

Abstract

The invention relates to the field of pipeline conveying equipment, and discloses a pipeline conveying device, a wear type pressure conveying pipeline and a manufacturing method hereof. The wear type pressure conveying pipeline comprises an inside liner (1), and a fiber layer which coils the periphery of the inside liner (1). The manufacturing method comprises the step of coiling a stress sharing fiber layer (2) with first design thickness (tf1) at the periphery of the inside liner (1) according to the extreme target raising value (delta d) of the wear thickness of the inside liner. The wear type pressure conveying pipeline manufactured by the manufacturing method has the advantages that the design thickness of the stress sharing fiber layer (2) is set according to the wear condition exposed to the inside liner (1), so that the design of the stress sharing fiber layer (2) can meet the original arrangement objective, and reasonable and accurate design ideal and direction are provided.

Description

Technical field [0001] The invention relates to the field of pipeline transportation equipment, in particular to a method for manufacturing a lossy pressure transportation pipeline. In addition, the present invention also relates to a lossy pressure conveying pipeline and a pipeline conveying equipment having the same. Background technique [0002] The use of pipelines as a means of transportation for long-distance transportation of liquid, gas or solid slurry is an important material transportation method in industrial production, and it is widely used. Among them, the pipeline as a means of transportation is constantly worn out and Withstand the working internal pressure and are collectively referred to herein as lossy pressure transmission pipelines. Typically, a concrete delivery pump continuously delivers concrete pressurized by the pump body to a predetermined location through a delivery pipe. The delivery pipe used to deliver the concrete here is a common lossy pressure d...

AI Technical Summary

Problems solved by technology

Since the pressure vessel is essentially a quasi-static structure, more attention is paid to its pressure bearing capacity, and it is usually designed to have a larger wall thickness in order to have a higher safety factor, but this leads to a larger mass

Therefore, due to the different performance of the lining (consumable pressure transmission pipelines are usually brittle linings to have wear resistance), there are large differences in working conditions and required safety levels, and the design ideas and methods of pressure vessels are not the same. Not easy to apply to consumable pressure delivery pipelines
