Description

Insulation insulator for plumbing {ADIABATIC LAGGING MATERIAL FOR PIPE}

The present invention relates to a heat insulating insulating material for pipes, and more particularly to a heat insulating insulating material for pipes to insulate the pipes using airgel and expanded polystyrene.

In general, various facilities are installed in production facilities or factories that produce various machines according to production purposes, and pipes of various purposes are connected between these facilities and facilities.

These pipes should be maintained at a constant temperature for various purposes, but the pipes installed between the equipment and the equipment continue to exchange heat with the outside, so to maintain the approved temperature, the pipe must be continuously supplied with energy. Loss occurs.

In order to reduce such heat loss, energy loss is generally reduced by installing an insulating material having heat insulation, water resistance, heat resistance, and physical and chemical stability on the outer circumferential surface of the pipe.

In order to solve the problem of heat insulation of the pipe, conventionally used polystyrene foam, glass fiber, polyurethane, airgel.

Expanded polystyrene is expanded polystyrene by the action of a blowing agent, and is widely used because of its excellent water resistance, insulation, soundproofing, and buffer resistance, but when used at a temperature of about 70 ° C. or higher, a problem occurs.

Glass fiber is excellent in heat insulation, heat resistance and physical stability, but has a fiber-like structure to absorb water through the capillary phenomenon, drainage takes a long time has a disadvantage of poor heat insulation.

Polyurethane is a high-molecular compound bonded by a urethane bond made of alcohol and isocyanic acid groups, and has excellent heat insulation and water resistance. However, when used at a temperature of about 100 ° C. or higher, shrinkage and melting occur similarly to polystyrene. .

In addition, the airgel is a fibrous structure containing air molecules from silicon oxide (SiO2), and has excellent heat insulation, heat resistance, sound insulation, and water resistance, but the material itself is expensive, and thus, the economy is inferior.

The present invention has been made to solve the above problems of the prior art to provide a heat insulating insulating material for pipes having excellent heat insulating components, water resistance and heat resistance using polystyrene and airgel, and requires little space for installation.

Insulation insulation for piping according to the invention is a cover formed of expanded polystyrene (expanded polystyrene) is formed so that the cut surface is separated in the circumferential direction of the pipe, the airgel is installed on the inner side of the cover when the cover and the pipe is in close contact with the pipe (aerogel).

Here, the outwardly facing jaw is formed on one side of the cover and the inwardly facing jaw is formed on the other side of the cover, and the inwardly facing and outwardly facing jaws of the cover are engaged.

In addition, the outward jaw and the inward jaw is formed with a coupling protrusion and the coupling groove is coupled to the coupling protrusion and the coupling groove when the outward jaw and the inward jaw is engaged.

In addition, the cutting surface is formed in parallel so that the pipe can be inserted, one side of the cut surface of the projection is formed with a projection jaw, the cutting surface opposite to the cutting surface is formed projection is formed with a groove coupled to the projection jaw.

In addition, the top and bottom of the cover is formed outwardly and the inwardly stepped frame is overlapped with each other to fit.

Insulation insulation for piping according to the present invention configured as described above is excellent in heat insulation, heat resistance and water resistance, and maintains excellent heat insulation even in a thin thickness bar requires less installation space, can be installed at a lower cost than economical The effect can be obtained.

Hereinafter, a preferred embodiment of the thermal insulation insulating material for piping according to the present invention will be described with reference to the accompanying drawings. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or convention of a user or an operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

In addition, the following examples are not intended to limit the scope of the invention, but merely illustrative of the components set forth in the claims of the present invention, which are included in the technical spirit throughout the specification of the present invention and components of the claims Embodiments including a substitutable component as an equivalent in may be included in the scope of the present invention.

Insulation material for pipes according to the present invention is a structure that can wrap the cylindrical pipe is made of a structure in which the aerosol is coupled to the inner surface of the cover and the cover made of a cylindrical foam polystyrene.

The heat resistance value indicating the degree of thermal insulation disturbance of the thermal insulation of the pipe is compared with foamed polystyrene, glass fiber and polyurethane through the test according to KS L 9016 (Plate heat flow meter method).

Insulation material for piping Expanded polystyrene Fiberglass Polyurethane Heat resistance (㎡K / W) 1.027 0.9 0.857 1.363

The test specimens used in this experiment had a thickness of 30 mm, and in the case of the thermal insulation material for piping, 22 mm foamed polystyrene and 8 mm airgel were laminated.

Judging from the thermal insulation performance of the pipe insulation insulating material used in the embodiment of the present invention based on the test data shown above, the heat resistance value of the pipe insulation insulation laminated with airgel and expanded polystyrene is 1.027 m 2 K / W foamed polystyrene The heat resistance value of 0.9 ㎡K / W and the glass fiber heat resistance value of 0.857 ㎡K / W and less than the polyurethane heat resistance value, the thermal insulation performance is better than the foamed polystyrene and glass fiber, and it is inferior to the polyurethane. have.

However, it can be seen that the polyurethane is not suitable for the pipe used in the plant because the melt and shrinkage occurs when used at a temperature condition of about 100 ℃ or more. On the other hand, in the case of the thermal insulation material for piping, it can be seen that it is suitable for the piping of the plant where a high temperature heat fluid flows because an airgel having excellent heat resistance is attached to the portion in contact with the pipe.

In addition, in the case of such a thermal insulation material for piping is remarkable thermal insulation can maintain the same thermal insulation thinner than the thermal insulation materials such as expanded polystyrene, glass fiber, etc. Therefore, the installation is not limited by space.

In addition, it is possible to maintain a lower installation cost than the case of using only airgel by laminating expanded polystyrene, which is inexpensive compared to insulating pipe using only airgel.

Since the thermal insulation thermal insulation material (1) for piping is limited in length at the time of manufacture, when the installation is installed in long pipes, the thermal insulation thermal insulation material (1) is subsequently installed. In this case, the thermal insulation thermal insulation material (1) for piping and the thermal insulation thermal insulation material for piping (1) There may be a play between) and heat dissipation of the pipe from this play.

Therefore, outwardly facing edges 10a and 20a and inwardly facing edges 10b and 20b are formed above and below the pipe so that outwardly facing edges 10a and 20a are inserted into the inwardly facing edges 10b and 20b and dissipated from these pipes. Can be reduced.
