3、cification replaces HH-I-558B in part.1. Scope1.1 This specification covers the composition, dimensions,and physical properties of metal-mesh covered mineral fiber(rock, slag, or glass) blanket and blanket-type pipe insulation(typically on 24 in. (610 mm) diameters or larger) for use oncooled surfac

4、es at temperatures operating below ambient to0F (18C) and on heated surfaces operating at temperaturesup to 1200F (649C). Specific applications outside the actualuse temperatures shall be agreed upon between the manufac-turer and purchaser.1.2 For satisfactory performance, properly installed protec-

5、tive vapor retarders or barriers shall be used on below ambienttemperature applications to reduce movement of moisturethrough or around the insulation to the colder surface. Failureto use a vapor barrier when insulating below ambient systemscreates conditions that, unless otherwise treated will lead

6、 toinsulation and system damage. Refer to Practice C 921 to aidmaterial selection. Although vapor retarder properties are notpart of this specification, properties required in SpecificationC 1136 are pertinent to applications or performance.1.3 The orientation of the fibers within the blanket isprim

7、arily parallel to the heated surface. This specification doesnot cover fabricated pipe and tank wrap insulation where theinsulation has been cut and fabricated to provide fiber orien-tation that is perpendicular to the heated surface.1.4 This standard does not purport to provide the perfor-mance req

When both sides are to be faced, units arepermitted to have the same or different types on the two sides.

32、(WarningThe user of this specification is advised that themaximum use temperature of some facings and adhesives willbe lower than the maximum use temperature of the insulation.For example, usually galvanized hexagonal wire-woven net-ting and tie wires or stitching perform well under continuousexposu

33、re to temperatures up to 392F (200C). Exposure totemperatures above this limit will cause the outer free zinclayer to peel. Though there are potential or occasional concernsfor corrosion conditions at various temperatures, galvanizedwire, stitching, or facings are not recommended for tempera-tures a

34、bove 500F (260C). In addition, the user of thisspecification shall ensure that sufficient insulation thickness isinstalled so that none of the accessory items (facings, adhesive,coatings, and lagging) are exposed to temperatures above theirmaximum use temperature.
