Abstract

The heat preservation type metal pipeline comprises a main body, the main body is composed of an outer layer body, an inner layer body and two bearing bodies, the two bearing bodies are symmetrically distributed on the two sides of the inner layer body, and the two ends of each bearing body are integrally welded to the inner wall of the outer layer body and the outer wall of the inner layer body correspondingly; the outer layer body, the inner layer body and the two bearing bodies form a stable integral structure, in order to adjust the pressure intensity by dividing and changing the inner cavity of the pressure control cavity so as to adapt to the heat preservation of the pipeline when the pressure intensity in the fluid cavity is different, the outer layer body, the inner layer body and the two bearing bodies form two symmetrical pressure control cavities with C-shaped sections, and the two pressure control cavities are communicated with each other. An arc-shaped pressure control partition plate arranged in the pressure control chamber dynamically divides the space in the pressure control chamber into an outer chamber and an inner chamber, and a fluid chamber is formed in the inner layer body. According to the heat preservation type metal pipeline, the pressure intensity and the temperature of the inner chamber and the fluid chamber are almost the same, and therefore heat exchange between the fluid chamber and the external environment is reduced, and the good heat preservation effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of metal pipes, in particular to a heat-insulating metal pipe. Background technique [0002] Metal pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. The main lines of metal pipelines for water supply, drainage, heat supply and gas supply in cities and long-distance metal pipelines for oil and gas transmission are mostly laid underground, while metal pipelines in factories are mostly laid on the ground for easy operation and maintenance. [0003] According to the Chinese patent CN113146925A, which discloses an automatic processing system for the production of thermal insulation layers of thermal insulation metal pipes, for steam pipelines, high temperature pipelines, low temperature pipelines, and pipelines with anti-scald and antifreeze requ...
