Embodiment 1

[0016] figure 1 Shown is a schematic cross-sectional view of the heat-insulating high-pressure pipe, which is composed of a metal pipe 1 , an heat-insulating pipe 2 , a fireproof foil 3 and a sheath 4 . The metal pipe 1 in the middle position is a circular pipe, and its outer pipe wall directly cooperates with the circular heat preservation pipe 2 inner holes. In this embodiment, the outer diameter of the metal pipe 1 is 8mm, the inner hole of the heat preservation pipe 2 is also 8mm, and the outer diameter of the heat preservation pipe 2 is 28mm. The fireproof foil 3 is a strip, and the fireproof foil 3 is evenly wound on the outer wall of the heat preservation pipe 2 to protect the safety of the heat preservation pipe 2 . The sheath 4 is integrally wrapped on the outer wall of the fireproof foil 3 . The present invention adopts layered nesting of different functional materials, so that the metal pipe 1 is located at the center, has good heat preservation effect, and strong...

Embodiment 2

[0018] The structure of this embodiment is exactly the same as that of Embodiment 1, and the application effect is also the same. Only the outer diameter of the metal pipe 1 is Φ25mm, and the inner hole of the heat preservation pipe 2 matched with it is also Φ25mm, and the outer diameter of the heat preservation pipe 2 is increased to 65mm year-on-year. .

Abstract

The invention discloses a heat insulation high-pressure pipe composed of a metal pipe, a thermal insulation pipe, a fireproof foil and a sheath covered with each other. The metal pipe in central position is a circular pipe with its outer wall matching with inner bore of the circular thermal insulation pipe directly, the band-shaped fireproof foil winding on outer wall of the thermal insulation pipe uniformly, and outer layer of the fireproof is packaged with a sheath in whole. The invention is produced by covering materials of different functions in layers, the metal pipe in the central position has good heat insulation effect, strong antifreezing capacity, because the pipe wall is not exposed, so the pipe is difficult to rust-eaten, which is used safely and reliably. The invnetion is especially suitable for pipes of transporting high-pressure hydraulic oil and steam medium in low temperature environment.

Description

technical field [0001] The invention relates to a high-pressure pipeline for transporting liquid medium, in particular, the invention relates to a high-pressure pipeline with an external insulation structure. Background technique [0002] The piping systems in hydraulic and pneumatic equipment are all high-pressure pipes. Under normal circumstances, high-pressure pipes are mainly metal pipes, and smooth-walled metal pipes meet the requirements for liquid medium transmission under normal temperature conditions. In cold winter season or low temperature conditions, because the exposed metal pipe wall is directly affected by the ambient temperature, the medium in the pipe is easy to freeze or become viscous, which affects the normal operation of supporting equipment, and once it stops, it will cause economic losses. In engineering, it is common to tie a certain thickness of thermal insulation material on the outer wall of the metal high-pressure pipe. This technical measure can...
