ASTM C547 PDF

Fiberglass and mineral wool products fall in this category. There is some confusion concerning the nomenclature used for these materials. Specifiers are cautioned to call out both the specific material and the ASTM type and grade when specifying these products. The standard contains five types classified primarily by maximum use temperature. The standard further classifies products by grade. The specified maximum thermal conductivity for all types is 0.

Fiberglass and mineral wool products fall in this category. There is some confusion concerning the nomenclature used for these materials. Specifiers are cautioned to call out both the specific material and the ASTM type and grade when specifying these products. The standard contains five types classified primarily by maximum use temperature. The standard further classifies products by grade. The specified maximum thermal conductivity for all types is 0. The standard also contains requirements for sag resistance, linear shrinkage, water-vapor sorption, surface-burning characteristics, hot surface performance, and non-fibrous shot content.

Further, there is an optional requirement in ASTM C for stress corrosion performance if the product is to be used in contact with austenitic stainless steel piping. These pipe insulation products may be specified with various factory-applied facings, or they may be jacketed in the field. Mineral fiber pipe insulations systems are also available with self-drying wicking material that wraps continuously around pipes, valves, and fittings. These products are intended to keep the insulation material dry for chilled water piping in high-humidity locations.

Mineral fiber pipe insulation sections are typically supplied in lengths of 36 inches, and are available for most standard pipe and tubing sizes. The standard contains seven types classified by maximum use temperature and thermal conductivity. These insulations are flexible and are normally supplied as batts or rolled blankets. The products may be specified with various factory-applied facings, or may be ordered unfaced. Mineral Fiber Block and.

El aislamiento de tuberas se puede moldear o precisin v acanalado con una o ms paredes dividido longitudinalmente y usados hasta una temperatura especificada. Los materiales se clasifican en cinco tipos de acuerdo con el mtodo de procesamiento utilizado para formar el material y las temperaturas de funcionamiento y en dos grados de acuerdo a las necesidades de calefaccin. El aislamiento de fibra mineral debe fabricarse a partir de sustancias minerales fundidos tales como roca, escoria, o vidrio y se procesa en forma fibrosa usando un aglutinante, y adhesivos cuando prefiere. Todos los productos deben ajustarse a los valores requeridos de eficacia en caliente la superficie, el contenido no fibrosa, temperatura de uso, resistencia a la deformacin, contraccin lineal, absorcin de vapor de agua, las caractersticas de la quema de la superficie, la conductividad trmica aparente, y la temperatura significa.

A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. Scope 1. Failure to use a vapor barrier can lead to insulation and system damage. Refer to Practice C to aid material selection.

Astm C547 Pipe Insulation

ASTM C Abstract This specification covers mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes. The pipe insulation may be molded or precision v-grooved with one or more walls split longitudinally and used up to a specified temperature. The materials are classified into five types according to the processing method used to form the material and the operating temperatures and into two grades according to heating requirements. The mineral fiber insulation should be manufactured from molten mineral substances such as rock, slag, or glass and processed into fibrous form using a binder, and adhesives when preferred. All products should conform to the required values of hot surface performance, non-fibrous content, use temperature, sag resistance, linear shrinkage, water vapor sorption, surface-burning characteristics, apparent thermal conductivity, and mean temperature.
