Problems solved by technology

Therefore, the construction cost is too high and the surface area occupied is large. However, due to the long time, the outer insulation material will pollute the environment after being weathered and broken, and the insulation effect will also be reduced.

Embodiment Construction

[0011] Embodiment is described below in conjunction with accompanying drawing:

[0012] see figure 1 and figure 2 , the present invention is a polyamide alloy nano-composite thermal insulation sleeve, which is a half-type thermal insulation sleeve used for petroleum transportation. The outer pipe 1 and the inner pipe 2 are coaxially socketed, and the inner pipe 2 is an oil delivery inner pipe; there are four casing interlayers 3 arranged between the outer pipe 1 and the inner pipe 2, and the outer pipe 1 and the inner pipe 2 are connected together. The inner tube 2 is fixedly connected together; the outer tube 1 and the inner tube 2 are divided into four interlayer spaces isolated from each other by the four casing interlayers 3, and the four interlayer spaces are all equal; two of the interlayer spaces are The hot water inlet pipe chamber 4, and the other two interlayer spaces are the hot water outlet pipe chamber 5. The hot water enters and exits in the interlayer space o...

Abstract

The present invention provides a kind of insulation casing specially used for petroleum transportation, which is composed of an outer pipe and an inner pipe coaxially socketed to form a casing, and the inner pipe is the inner pipe for oil transportation; Between the pipe and the inner pipe, the outer pipe and the inner pipe are fixedly connected; The layers are divided and circulated. The thermal insulation sleeve of the present invention clearly solves the problem that thermal insulation conditions must be provided in the oil transportation process, and has three advantages. First, it greatly reduces the construction cost of the petroleum transportation thermal insulation project, and secondly, it improves the thermal insulation during the petroleum transportation process. The third effect is to optimize the environment and save resources.

Description

technical field [0001] The invention relates to an industrial pipeline, in particular to a half-type thermal insulation sleeve specially used for oil transportation. Background technique [0002] At present, the selection of thermal insulation materials used in domestic oil insulation transportation projects is constantly updated. On the basis of felt, asbestos cloth, or perlite wool and other materials wrapped around the outer pipe to play a role in thermal insulation, there are new insulation sleeves. Pipes such as plastic PE, PVC, PPR jackets and polyurethane insulation sleeves, composite insulation sleeves, etc. [0003] No matter what material or form is used, the principle is to achieve the effect of long-term heat preservation through the purpose of heat supply, heat storage and heat preservation. In order to achieve this goal, the oil sector often adopts the method of bundling the three pipes of the oil pipeline, the hot water inlet pipe, and the hot water outlet pi...
