A heat-insulating pipe shell and its installation method

Abstract

The invention relates to a heat-preservation pipe shell and a mounting method thereof. The heat-preservation pipe shell structurally comprises a bottom layer heat-preservation structure, a middle layer heat-preservation structure and an outer layer heat-preservation structure in sequence from inside to outside; reinforcing base material structures are arranged on the inner surface and the outer surface of each layer of heat-preservation structures for fixing heat-preservation layers; and concave-convex modules are arranged at the two ends of each layer of heat-preservation structures, thus thetwo heat-preservation pipe shells can be mutually buckled tightly, and the heat-preservation effect is good. A sliding device and a rolling body are arranged between the two ends of the bottom layerheat-preservation structure and a high-temperature pipeline, the overall heat-preservation pipe shell can be supported to slide on the high-temperature pipeline, the heat-preservation pipe shell can be precast in advance, on-site construction, mounting and dismounting are quick and safe, and the labor intensity, the construction risk and the maintenance cost of on-site construction can be reduced;and a thin air layer is arranged among the bottom layer heat-preservation structure of the heat-preservation pipe shell, the high-temperature pipeline and the sliding device, thus the energy saving effect is greatly improved, the problem that the heat-preservation layer is excessively thick is solved, and the heat-preservation cost can be lowered reasonably.

Description

Technical field [0001] The invention relates to the field of thermal insulation engineering, and is a thermal insulation composite structure, in particular to a thermal insulation pipe shell and an installation method thereof. Background technique [0002] In the heat preservation project of the medium and high temperature pipelines (300℃~800℃) in the prior art, the heat preservation materials mainly used are high temperature rock wool, aluminum silicate or magnesium silicate, etc., which are cut and coated on site during use. It is then covered with iron sheet or color steel sheet. These thermal insulation materials are loose and unshaped, which makes the work site have the disadvantages of high working intensity and high risk. Therefore, under the premise of ensuring the thermal insulation effect of the thermal insulation tube shell, how to maintain the tube shell specifications, safety, durability and beautiful appearance is an engineering problem that needs to be solved urge...
