Description

Technical Field

[0001] This utility model relates to the field of steam pipelines, specifically to a flexible composite insulation sleeve for steam pipelines. Background Technology

[0002] Steam pipelines are widely used to transport high-temperature steam in numerous industrial production processes and civil applications such as district heating. To reduce heat loss during steam transport, improve energy efficiency, and ensure the safety of the surrounding environment, effective insulation of steam pipelines is crucial.

[0003] Traditional methods of insulating steam pipes have many drawbacks. For example, on-site pouring or applying insulation materials is complex, requires specialized personnel and a large amount of equipment, has a long construction period, and makes it difficult to ensure the uniformity of the insulation layer. While using prefabricated rigid insulation materials, such as rock wool pipe shells or polyurethane foam pipe shells, is relatively simple to install, it makes pipe maintenance, repair, and modification extremely inconvenient.

[0004] Therefore, it is important to provide a flexible composite insulation sleeve for steam pipes that can guarantee heat insulation and thermal insulation. Summary of the Invention

[0005] This utility model aims to provide a flexible composite insulation sleeve for steam pipelines, with the specific solution as follows:

[0006] A flexible composite insulation sleeve for steam pipes includes a working pipe, an inner insulation layer, a high-temperature resistant anti-radiation layer, a middle heat insulation layer, and an outer protective layer arranged in sequence. The outer protective layer includes an outer heat insulation layer, a nano-airbag reflective layer, and an outer metal layer arranged in sequence.

[0007] The inner insulation layer is an aerogel felt layer with a thickness of 20-30 mm.

[0008] The high-temperature resistant anti-radiation layer is a ceramic fiber heat insulation cotton layer.

[0009] The intermediate insulation layer is an aluminum silicate layer.

[0010] The high-temperature resistant anti-radiation layer is provided with galvanized steel strips to bind aluminum foil cloth.

[0011] The intermediate insulation layer is provided with aerogel felt binding straps.

[0012] The high-temperature resistant anti-radiation layer is provided in several groups.

[0013] The aerogel felt layer, ceramic fiber insulation cotton layer, and aluminum silicate layer of this invention are all non-flammable materials, which improves the fire safety of steam pipes. Furthermore, the above design effectively ensures the heat insulation and thermal insulation properties of this invention. Attached Figure Description

Detailed Implementation

[0016] The following is combined Figure 1 Further explanation:

[0017] A flexible composite insulation jacket for steam pipes includes a working pipe 1, an inner insulation layer 2, a high-temperature resistant anti-radiation layer 3, a middle insulation layer 4, another high-temperature resistant anti-radiation layer 5, and an outer protective layer arranged sequentially. The outer protective layer includes an outer insulation layer 51, a nano-airbag reflective layer 52, and an outer metal layer 53 arranged sequentially. The nano-airbag reflective layer 52 has excellent flame-retardant and heat-insulating effects, while the outer metal layer 53 provides protection.

[0018] The inner insulation layer 2 is an aerogel felt layer with a thickness of 20-30 mm. The aerogel felt layer has an extremely low thermal conductivity, forming an insulation barrier that can significantly reduce heat loss from the steam pipe and improve energy utilization efficiency.

[0019] The high-temperature resistant anti-radiation layer 3 is a ceramic fiber insulation layer. The ceramic fiber insulation layer is lightweight, high-temperature resistant, has good thermal stability, and low thermal conductivity.

[0020] The intermediate insulation layer 4 is an aluminum silicate layer. Aluminum silicate has excellent thermal insulation properties.

[0021] The high-temperature resistant anti-radiation layer 3 is equipped with galvanized steel strips to bind aluminum foil cloth.

[0022] The intermediate insulation layer 4 is equipped with aerogel felt binding straps.

[0023] Several sets of high-temperature resistant anti-radiation layers are set (2 sets are shown in the figure).
