A soundproofing material including a porous body having a cell structure and including inorganic fibers other than asbestos, wherein an average cell diameter is more than 300 &#x3bc;m and 1000 &#x3bc;m or less, a bulk density is 0.007 to 0.024 g/cm, and a flow resistivity is 170,000 to 2,000,000 Ns/m.

Soundproofing material

A novel pipe cover is disclosed that can suppress thermal deterioration in a member that is positioned opposite to the pipe, and can control the temperature inside the pipe within a given range, even when a high-temperature fluid circulates through the pipe. The pipe cover is used to cover the outer periphery of a pipe, and includes a base that is formed of a tubular heat insulator, and a surface member that covers the outer surface of the base, a heat radiation section and a heat radiation-suppressing section being provided on the outer surface of the surface member, and the emissivity of the heat radiation section at a wavelength of 2 to 15 &#x3bc;m being higher than the emissivity of the heat radiation-suppressing section at a wavelength of 2 to 15 &#x3bc;m.
