Calcium Silicate<\/span><\/b><\/p>\n

Calcium Silicate thermal
\ninsulation is defined by ASTM as insulation composed principally of hydrous
\ncalcium silicate, and which usually contains reinforcing fibers.<\/span><\/p>\n

Calcium Silicate Block
\nand Pipe Insulation are covered in ASTM C533. The standard contains three
\ntypes, classified primarily by maximum-use temperature and density.<\/span><\/p>\n

The standard limits
\nthe operating temperature between 80\u00b0 and 1,700\u00b0F.<\/span><\/p>\n

Calcium Silicate
\nInsulation Products<\/span><\/b><\/p>\n

Calcium Silicate pipe
\ninsulation is supplied as hollow cylinder shapes, split in half lengthwise, or
\nas curved segments. Pipe insulation sections typically are supplied in lengths
\nof 36″ and are available in sizes to fit most standard pipe sizes. Available
\nthicknesses range from 1″ to 3″ (in one layer). Thicker insulation is supplied
\nas nested sections.<\/span><\/p>\n

Calcium Silicate
\nblock insulation is supplied as flat sections in lengths of 36″; widths of 6″,
\n12″, and 18″; and thickness from 1″ to 4″. Grooved block is available for
\nfitting block to large-diameter curved surfaces.<\/span><\/p>\n

Special shapes, such
\nas valve or fitting insulation, can be fabricated from standard sections.<\/span><\/p>\n

Calcium Silicate is
\nnormally finished with a metal or fabric jacket for appearance and weather
\nprotection.<\/span><\/p>\n

The specified
\nmaximum thermal conductivity for Type I is 0.41 Btu-in\/(h?ft\u00b2?\u00b0F) at a mean
\ntemperature of 100\u00b0F. The specified maximum thermal conductivity for Types IA
\nand Type II is 0.50 Btu-in\/(h?ft\u00b2?\u00b0F) at a mean temperature of 100\u00b0F.<\/span><\/p>\n

The standard also
\ncontains requirements for flexural (bending) strength, compressive strength,
\nlinear shrinkage, surface-burning characteristics, and maximum moisture content
\nas shipped.<\/span><\/p>\n

Typical applications
\ninclude piping and equipment operating at temperatures above 250\u00b0F, tanks,
\nvessels, heat exchangers, steam piping, valve and fitting <\/a>insulation,
\nboilers, vents, and exhaust ducts.<\/span><\/p>\n
