ASTM C – 17 Standard Specification for Mineral Fiber Pipe Insulation

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 values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.


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. This standard does not purport to address all of the safety concerns, if any, associated with its use. Standards Subsctiption may be the perfect solution.

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.

Mineral fiber pipe insulation sections are typically supplied in lengths of 36 inches, and are available for most standard pipe and tubing sizes.

Exploring Insulation Materials

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. Fibrous insulations are composed of small-diameter fibers that finely divide the air space. Subscription pricing is determined by: See Annex A1 of this standard. Each of these types is further classified by compressive resistance.

Add to Alert PDF. This specification covers mineral fiber pipe insulation that are formed into hollow cylinders for standard pipe and tubing sizes.

ASTM C – Standard Specification for Mineral Fiber Pipe Insulation

The fibers may be organic or inorganic and they are normally but not always held together by a binder. Mineral Asm Fiberglass and Mineral Wool.

These insulations are flexible and are normally supplied as batts or rolled c5477. The standard also contains requirements for sag resistance, linear shrinkage, water-vapor sorption, surface-burning characteristics, hot surface performance, and non-fibrous shot content. There is some confusion concerning the nomenclature used for these materials. You may delete a document from your Alert Profile at any time.

Please first verify your email before subscribing to alerts. Mineral Fiber Fiberglass and Mineral Wool Mineral fiber insulations are defined by ASTM as insulations composed principally of fibers manufactured from rock, slag, or glass, with or without binders. The mineral fiber insulation should be manufactured from molten mineral substances such as rock, slag, or glass and qstm into fibrous form using a binder, and adhesives when preferred.
