Pipeline thermal insulation tube case

Abstract

The invention discloses a pipeline thermal insulation tube case, comprising a tube case body with a hollow cylindrical structure; the tube case body comprises two semi cases with the consistent structures; the internal surfaces of the semi cases are arranged in a wavy shape in the axial direction; grooves are arranged at the outside ends of the end surfaces of the semi cases; convex steps are arranged at the outside ends of the other end surfaces of the semi cases; the groove bottom plane of the groove and the step top plane of the convex step are provided with toothed grains for being filled with viscose; a lock ring is arranged at the cylindrical outer surface of each semi case; two rope parts for fixedly connecting the two semi cases are connected onto each lock ring. The pipeline thermal insulation tube case has the advantages of simple structure, convenient operation and high practicability, can lock more heat without heat diffusion and can effectively preserve heat; the radiating area of the thermal insulation tub case and a conveying pipeline is small, thus further ensuring the efficient thermal insulation; the assembly and disassembly are convenient, the construction difficulty is low and the production cost of the thermal insulation tube case is low.

Description

technical field [0001] The invention relates to an auxiliary part for external use of a conveying pipeline, in particular to a pipeline heat preservation shell, which belongs to the technical field of pipeline heat preservation. Background technique [0002] Insulation pipelines are widely used in liquid and gas transportation pipe networks. In insulation transportation pipelines, pipeline insulation is a very important link. The success of this link is directly related to whether the pipeline can be officially put into use. [0003] At present, the general insulation pipeline uses shell insulation. There are two main types of existing thermal insulation shells. One is a circular tube with a fracture along the axial direction. When installing, the thermal insulation shell is opened to wrap the tube for installation; the other is two half tubes. The shell is formed into a round tube. Each joint surface of these structures is a plane, and it is extremely easy to cause gaps a...

AI Technical Summary

Problems solved by technology

The joint surfaces of these structures are all flat, and it is extremely easy to cause gaps at the joint surfaces during installation, which directly affects the thermal insulation effect

The structure of these shells inevitably encounters the problem of "thermal bridge", that is to say, the heat radiation radiates outward through the gap between the shells and the shells, resulting in heat loss, thus affecting the insulation effect

[0004] In addition, in the prior art, the gene
