Provided is a fire-resistant filler which is formed inside a pipe to divide the space inside the pipe, and has, on the surface thereof, a coating layer including expandable graphite. As the coating layer expands by flame or heat, the filler blocks the pipe by filling the space inside the pipe. Thus, the filler can prevent the spread of the fire by quickly responding to the fire.

INSULATED HIGH-TEMPERATURE GASKET HAVING MULTIPLE SEALING LAYERS
The present invention relates to an insulated high-temperature gasket having a plurality of sealing units, the gasket comprising: a gasket main body formed of a metal material and having serrated bent units on upper and lower surfaces thereof; a plurality of sealing layers formed on a surface of the main body, for improving insulating and heat resistant properties; and a wing portion opened to outward direction from an outer circumferential unit of the main body and having an elastic body inserted therein such that an outer ring can be installed therein, wherein the gasket further comprises an organic/inorganic thin film coating layer formed on a surface of the sealing layer and an inorganic layer formed on a surface of the organic/inorganic thin film coating layer. According to the present invention, because the insulated high-temperature gasket having the plurality of sealing layers is used, airtightness of a pipe used to transport a fluid can be increased, and durability and heat resistance of the gasket can be maximized. At the same time, because it is easy to manufacture and process the gasket, versatility in high-temperature and high-pressure environments can be noticeably improved, and the sealing member can be easily attached and detached to easily carry out operations.

The present invention relates to gaskets and, more specifically, to gaskets including sealing materials having a groove portion formed on one surface thereof, and filling materials positioned between the sealing materials. The present invention has the effect of securing improved air-tightness and higher stability and restoring force compared to conventional gaskets.
The present invention provides a catalytic reaction apparatus comprising a coating composition for a catalyst and a method for coating the coating composition, the apparatus comprising a catalyst portion which is coated with a coating composition comprising 1-15 parts by weight of tungsten, 1-15 parts by weight of vanadium, 35-55 parts by weight of titanium, and 30-45 parts by weight of oxygen. According to the present invention, a reduction in catalytic reaction efficiency in a specific temperature environment can be prevented, and thus wide usability can be maximized.
