Abstract

The invention relates to a heat insulation and cold insulation prefabricated pipeline shell for protecting a pipeline from the outside. A preparation method comprises the following steps of (1) prefabricating a set of transparent mold; (2) preparing epoxy vinyl ester resin slurry in a shading environment; (3) preparing an internal epoxy vinyl ester resin base layer; (4) coating the outer part of the epoxy vinyl ester resin base layer with a layer of glass fiber layer; (5) preparing the prefabricated pipeline shell; and (6) taking out the prefabricated pipeline shell. The pipeline shell is prefabricated and formed in advance, is excellent in properties of heat insulation and cold insulation, and is durable, and the cost is reduced.

Description

technical field [0001] The invention relates to a prefabricated pipe shell, in particular to a prefabricated pipe shell for external protection of heat and cold pipes. Background technique [0002] Pipeline crossing project is a pipeline project in which transportation pipelines are laid underwater or underground through rivers, lakes, railways, highways and other areas. [0003] Pipelines are easily corroded in underwater or underground environments, and are generally protected by coating anti-corrosion coatings. However, this method has a short protection period and still poses safety hazards when used for a long time. Contents of the invention [0004] Aiming at the above problems, the present invention proposes a prefabricated pipe shell for heat preservation and cold preservation, which is prefabricated in advance, has excellent heat preservation and cold preservation performance, saves cost and is durable. [0005] The specific technical scheme is as follows: [00...
