Problems solved by technology

[0002] The direct buried pipe can be directly buried in the ground or in the water, the construction is simple and fast, and the overall cost is low. However, when the existing direct buried pipe is installed with a crane, the hook directly hangs on the nozzle of the direct buried pipe. The tube is easy to fall off, posing a safety hazard

Embodiment Construction

[0016] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 , figure 2 , image 3 As shown, the prefabricated direct-buried thermal insulation pipe includes a steel pipe layer 1, an insulation layer 2 and a protective layer 3 arranged sequentially from inside to outside. The edges of both ends of the steel pipe layer 1 leak out of the protective layer 3. The outer layer 102 is formed. The inner layer 101 and the outer layer 102 are separated from each other to form a cavity. The inner layer 101 and the outer layer 102 are fixed by the connector 4 . The outer layer 102 is provided with openings 5 ​​at both ends.

[0018] Such as Figure 4 As shown, in the preferred embodiment, the openings 5 ​​are two of different sizes arranged along the pipe wall, the steel pipe layer 1 i...

Abstract

The invention provides a prefabricated directly-buried heat preservation pipe and relates to combination pipes. The invention aims to solve the problem that the conventional directly-buried pipes are prone to fall off when being installed by using a crane. The prefabricated directly-buried heat preservation pipe comprises a steel pipe layer, a heat preservation layer and a protection layer, which are arranged from inside to outside successively; the edges of the two ends of the steel pipe layer are exposed out of the protection layer; the steel pipe layer comprises an inner layer and an outer layer which are separated from each other to form a cavity; the inner layer and the outer layer are fixed via connecting members; the two ends of the outer layer are provided with openings. With the combined layers, the airtightness of the inner layer is guaranteed and the lifting safety is guaranteed.

Description

technical field [0001] The direct buried pipe is suitable for heat preservation and cold preservation projects of various media in the range of -50°C to 150°C. It is widely used in heat preservation and cold preservation projects in urban central heating, warm rooms, cold storage, coal mines, oil ports, and chemical industries. Background technique [0002] The direct buried pipe can be buried directly in the ground or in the water. The construction is simple and fast, and the overall cost is low. However, when the existing direct buried pipe is installed by a crane, the hook directly hangs on the nozzle of the direct buried pipe. The tube is easy to fall off, which poses a safety hazard. Contents of the invention [0003] The object of the present invention is to provide a prefabricated direct-buried thermal insulation pipe with safe lifting. For realizing above-mentioned technical purpose, the technical scheme that the present invention adopts is as follows: [0004] T...
