[0029] A pipe insulation mat is used to wrap the outer circumference of a pipe that transports high-temperature media. The pipe insulation mat is a bendable coil and includes a fireproof cloth 1, a first Velcro 2, and a filling layer 3.

[0030] The fireproof cloth 1 covers and seals the filling layer 3;

[0031] The first Velcro 2 includes a first hook-side strip 21 and a plurality of first loop-side strips 22;

[0032] The first hook surface strip 21 and the first loop surface strip 22 extend in a direction parallel to the axis of the pipe respectively;

[0033] The first hook-side strip 21 is fixed to the inner surface of one side of the fireproof cloth 1 parallel to the axial direction of the pipe; one first fleece-side strip 22 is fixed to the outer surface of the other side of the fireproof cloth 1 parallel to the axial direction of the pipe, and the remaining plurality of first fleece-side strips 22 are arranged at intervals and fixed to the outer peripheral surface of the fireproof cloth 1;

[0034] The filling layer 3 is made of thermal insulation material.

[0035] Figure 1 This is a structural diagram of an embodiment of a pipe insulation pad of the utility model. Figure 2 This is a schematic diagram of the cross-sectional structure of the pipe thermal insulation pad of the present invention.

[0036] When in use, a pipe insulation pad of the present invention is covered on the outer circumference of a pipe transporting a high-temperature medium, and while pulling up one side of the fireproof cloth 1 fixed with the first hook surface strip 21, the other side of the fireproof cloth 1 fixed with the first fleece surface strip 22 is pressed, and then the first hook surface strip 21 is pasted on the most suitable first fleece surface strip 22, so that the pipe insulation pad is tightly wrapped around the outer circumference of the pipe, thereby completing the installation of a pipe insulation pad.

[0037] The outer peripheral surface of the fireproof cloth 1 is arranged with a plurality of the first fleece strips 22, so that the pipe insulation pad can be applied to pipes of different diameters and has better versatility.

[0038] The pipe thermal insulation pad is a bendable coil, so that the pipe thermal insulation pad can be more closely fitted to the outer circumference of the pipe, and can also improve the convenience of storage of the pipe thermal insulation pad and the convenience of construction operation.

[0039] The first Velcro 2 extends and covers both sides of the fireproof cloth 1 parallel to the axial direction of the pipe, so that the pipe insulation pad has a more sealing effect; wrapping the filling layer 3 with the fireproof cloth 1 can prevent the material of the filling layer 3 from leaking out, thereby increasing the service life of the pipe insulation pad.

[0040] Furthermore, the pipe insulation pad also includes a second Velcro 4;

[0041] The second Velcro 4 includes a second hook-side strip 41 and a second loop-side strip 42;

[0042] The second hook-side strip 41 is fixed to the inner surface of one side of the fireproof cloth 1 perpendicular to the axial direction of the pipe; the second fleece-side strip 42 is fixed to the outer surface of the other side of the fireproof cloth 1 perpendicular to the axial direction of the pipe.

[0043] like Figure 1 As shown, when wrapped around the outer surface of the pipe, the two adjacent pipe insulation pads can be connected by the second Velcro 4, thereby avoiding the formation of an installation gap between the two pipe insulation pads and preventing heat from being lost through the installation gap of the pipe insulation pads.

[0044] Furthermore, the outer surface of the fireproof cloth 1 is coated with silica gel.

[0045] Coating silica gel on the outer surface of the fireproof cloth 1 can improve the waterproof and corrosion-resistant properties of the pipeline insulation pad.

[0046] Furthermore, the outer surface and inner surface of the fireproof cloth 1 are coated with aluminum foil.

[0047] Coating aluminum foil on the inner and outer surfaces of the fireproof cloth 1 can not only improve the waterproof performance of the pipe insulation pad, but also improve the light and heat reflection performance of the pipe insulation pad to the inside and outside. While improving the thermal insulation effect, it can also improve the anti-aging performance of the pipe insulation pad.

[0048] Preferably, the material of the fireproof cloth 1 is composite glass fiber;

[0049] The filling layer 3 is made of micro-nano fiber aerogel, glass fiber, foamed silica gel, aerogel composite material, porous vacuum silicon or polyimide foam.

[0050] The pipe insulation mat can have a better cost advantage by selecting composite glass fiber as the fireproof cloth 1. High silica glass fiber or aluminum foil glass fiber is preferred.

[0051] Selecting micro-nano fiber aerogel, glass fiber, foamed silica gel or polyimide foam as the filling layer 3 can make the pipeline thermal insulation pad have good thermal insulation performance.

[0052] Even if the filling layer 3 of the pipe thermal insulation pad is made of glass fiber, construction workers will not come into direct contact with the glass fiber during the construction process, so it will not affect the health of the construction workers.

[0053] Preferably, the thickness of the fireproof cloth 1 is 2-5 mm;

[0054] The thickness of the filling layer 3 is 2-10 mm.

[0055] The thickness of the fireproof cloth 1 and the thickness of the filling layer 3 can be selected according to the required thermal insulation effect.

[0056] Example 1: The fireproof cloth 1 is a 0.06mm thick aluminum foil fiberglass cloth, and the filling layer 2 is a 2mm thick micro-nano fiber aerogel, which is made into the pipe insulation pad and wrapped around the outer surface of a steam pipe with a surface temperature of 100°C. After the temperature stabilizes, the outer surface temperature of the pipe insulation pad is lower than 60°C.

[0057] Example 2: The fireproof cloth 1 is a 0.6 mm thick silicone-coated glass fiber cloth, and the filling layer 2 is a 10 mm thick micro-nano fiber aerogel. The pipe insulation pad is made and wrapped around the outer surface of a steam pipe with a surface temperature of 200°C. After the temperature stabilizes, the outer surface temperature of the pipe insulation pad is lower than 50°C.

[0058] Example 3: The fireproof cloth 1 is a 1.2 mm thick high-silica fireproof cloth, and the filling layer 2 is a bonded body of a 10 mm thick micro-nano fiber aerogel and a 10 mm thick aerogel composite material. The pipe insulation pad is made and wrapped around the outer surface of a steam pipe with a surface temperature of 600°C. After the temperature stabilizes, the outer surface temperature of the pipe insulation pad is lower than 80°C.

[0059] In summary, if Figure 1-2 In the embodiment of the present invention shown, the pipe insulation pad not only has a good thermal insulation effect, but also has a simple structure and a plurality of wrapping circumferences to choose from, which can effectively improve the construction work efficiency of wrapping around the pipe.

[0060] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
