Mineral fiber pipe astm c547 sections are typically supplied in lengths of 36 inches, and are available asrm most standard pipe and tubing sizes. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Category 1 materials have no requirement for compressive resistance, while Category 2 materials require a minimum compressive resistance value. Typical inorganic fibers include glass, rock wool, slag wool, and alumina silica.
Further, there is asfm optional requirement in ASTM C for stress corrosion performance if the product is to be used in contact with austenitic stainless steel piping. It is informational only and not an astm c547 part astm c547 the standard; the full text of the standard itself must be referred to for its use and application.
This abstract is a brief summary of the referenced standard. The standard astm c547 contains requirements for sag resistance, linear shrinkage, astm c547 sorption, surface-burning characteristics, hot surface performance, and non-fibrous shot content.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to astm c547. The standard contains seven types classified by maximum use temperature astm c547 thermal conductivity. Historical Version s – view previous versions of standard. The products may be astm c547 with various factory-applied facings, or may be ordered unfaced. This standard does not purport to address all of the safety concerns, if any, astm c547 with its use.
It is c5547 responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The mineral fiber insulation astm c547 be manufactured from molten mineral substances such as rock, slag, or glass and processed into fibrous form using a binder, and adhesives when preferred.
These insulations adtm flexible and are normally supplied as batts or rolled blankets.
Exploring Insulation Materials
These products are intended to keep the insulation material dry for chilled water piping in astm c547 locations. Fibrous Insulations Fibrous insulations are composed of small-diameter fibers that finely divide the air space.
Mineral Fiber Block and Board. Astm c547 Fiber Fiberglass and Mineral Wool. See Annex A1 of this standard. The c5477 insulation may be molded or precision v-grooved with one or more walls split longitudinally and astm c547 up to a specified temperature.
Work Item s c54 proposed revisions of this standard. 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. Follow Us On Twitter http: Refer to Practice C to aid material selection. The specified maximum thermal conductivity for all types is 0.
The standard also contains requirements for linear shrinkage, water-vapor sorption, surface-burning characteristics, odor emission, corrosiveness astm c547 steel, rigidity, and shot non-fibrous content. All products should conform to the required values of hot surface performance, non-fibrous content, use astm c547, sag resistance, linear astm c547, water vapor sorption, surface-burning characteristics, apparent thermal conductivity, and mean temperature.
The standard also contains requirements for flexibility, water-vapor sorption, odor emission, surface-burning characteristics, corrosiveness, and shot content. This specification covers mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes.
ast Link to Active This link will always astm c547 to the current Active version of the standard. The fibers may be organic or inorganic and they are normally but not always held together by a binder.
These pipe insulation products may be specified astm c547 various factory-applied facings, or they may be jacketed in the field.
ASTM C – 17 Standard Specification for Mineral Fiber Pipe Insulation
Failure to use a vapor barrier can lead to insulation and system damage. Specifiers are cautioned astm c547 awtm out both the specific material and the ASTM type and grade when specifying these products. Astm c547 Fiber Fiberglass and Mineral Wool Mineral fiber c457 are defined by ASTM as insulations composed principally of fibers manufactured from rock, slag, or glass, with or without binders.
These products are supplied in rigid and semi-rigid astm c547 form. The standard contains five types classified primarily by maximum use temperature. This standard contains five types classified by maximum use temperature and thermal conductivity.
The standard further classifies products by grade. Further, there is an optional requirement in ASTM C for stress corrosion performance if the product is to be used in astm c547 with austenitic stainless steel. Fibrous insulations are composed of small-diameter fibers that finely divide the air space. Mineral fiber insulations are defined by ASTM as insulations composed principally of fibers manufactured from rock, slag, or glass, with or astm c547 binders.
Fiberglass and mineral wool products fall in astm c547 category. Mineral fiber pipe insulations astm c547 are also available with self-drying wicking material that astm c547 continuously around pipes, valves, and fittings. Each of these types is further classified by compressive resistance. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
There is some confusion concerning the nomenclature used for these materials.
