Fiber blanket

RCF is sold in a variety of forms, such as loose fiber, blanket, boards, modules, cloth, cements, putties, paper, coatings, felt, vacuum-formed shapes, rope, braid, tape, and textiles. The products are principally used for industrial appHcations as insulation in furnaces, heaters, kiln linings, furnace doors, metal launders, tank car insulation, and other uses up to 1400°C. RCF-consuming industries include ferrous and nonferrous metals, petrochemical, ceramic, glass, chemical, fertiH2er, transportation, constmction, and power generation/incineration. Some newer uses include commercial fire protection and appHcations in aerospace, eg, heat shields and automotive, eg, catalytic converters, metal reinforcement, heat shields, brake pads, and airbags. 

Interna] Insulation The practice of insulating within the vessel (as opposed to applying insulating materials on the equipment exterior) is accomplished by the use of fiber blankets and hghtweight aggregates in ceramic cements. Such construction frequently incorporates a thin, high-alloy shroud (with slip joints to allow for thermal expansion) to protect the ceramic from erosion. In many cases this design is more economical than externally insulated equipment because it allows use of less expensive lower-alloy structural materials.

Ceramic fiber blankets have been used for several years to line fired heaters. Usually, the blankets are installed in heaters by impaling them on stainless steel studs. 

If clean fuels are fired, such as natural gas or even Number 2 oil, ceramic fiber blankets are installed on type 310 stainless steel studs. Layers are overlapped to prevent heat leaks and the stud pattern is devised to support the blanket over the expected life of the lining. 

Batt/Blanket - A flexible roll or strip of insulating material in widths suited to standard spacings of building structural members (studs and joists). They are made from glass or rock wool fibers. Blankets are continuous rolls. Batts are pre-cut to four or eight foot lengths. 

Porous fiber blankets - Blanket material of fine fibers, usually glass minimum cost and easy installation but not an adequate insulation for most cryogenic applications. 

Superheated steam, exhaust ducting, and some process operations are the few piping applications in the temperature range of 1000 to 1600°F (538 to 871°C). Again, caldum silicate, expanded perlite, and mineral wool are the usual materials employed. These products reach their temperature limits within this range, and higher temperature requirements are usually met by ceramic fiber blanket materials wrapped around the piping.
