Standard Specification for Perpendicularly Oriented Mineral Fiber Roll and Sheet Thermal Insulation for Pipes and Tanks

ABSTRACT
This specification covers perpendicularly oriented mineral fiber roll and sheet thermal insulation for use on the flat, curved, or round surfaces of pipes and tanks. The orientation of the rock, slag, or glass fibers within the roll or sheet insulation is essentially perpendicular to the heated/cooled surface. Materials covered in this specification do not include flat block, board, duct wrap, or preformed pipe mineral fiber insulation where the insulation fiber orientation is generally parallel to the heated/cooled surface. In low-temperature applications, properly installed protective vapor retarders should be used to prevent water vapor from moving through or around the insulation towards the colder surface. The materials are classified into six types according to the maximum use temperature and maximum apparent thermal conductivity and into two categories according to minimum compressive resistance. Samples taken from the materials should be tested according to the recommended procedures and should conform to the required values of corrosiveness to steel, stress corrosion to austenitic stainless steel, shot content, maximum use temperature, maximum exothermic temperature rise, and compressive resistance.
SCOPE
1.1 This specification covers the composition, dimensions, and physical properties of compression-resistant, perpendicularly oriented mineral fiber (rock, slag, or glass) roll and sheet insulation intended for use on flat, curved, or round surfaces up to 1000°F (538°C). This product (pipe and tank insulation) is typically used on nominal 24 in. (610 mm) or greater diameter surfaces. For specific applications, the actual use temperatures and diameters shall be agreed upon between the manufacturer and the purchaser.
1.2 The orientation of the fibers within the roll or sheet insulation is essentially perpendicular to the heated/cooled surface (parallel to heat flow). This specification does not apply to flat block, board, duct wrap, or preformed pipe mineral fiber insulation where the insulation fiber orientation is generally parallel to the heated/cooled surface (across the heat flow).
1.3 For satisfactory performance, properly installed protective vapor retarders must be used in low-temperature (below ambient) applications to prevent movement of water vapor through or around the insulation towards the colder surface.
1.4 The values stated in inch-pound units are to be regarded as standard. The SI equivalents of inch-pound units are given in parentheses for information only and may be approximate.
1.5 When the installation or use of thermal materials, accessories, and systems may pose safety or health problems, the manufacturer shall provide the user-appropriate current information regarding any known problems associated with the recommended use of the company's products and shall also recommend protective measures to be employed in their safe utilization. The user shall establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4.1.2 Categories:
4.1.2.1 Category 1—Greater minimum compressive resistance properties are required.
4.1.2.2 Category 2—Lesser minimum compressive resistance properties are required.
5. Ordering Information
5.1 The type, category, dimensions, and facing shall be specified by the purchaser. Shot content and delivered density
certification may be requested by the purchaser after consulting with the supplier or the manufacturer.
6. Materials and Manufacture
6.1 Composition— Mineral fiber roll or sheet shall be composed of rock, slag, or glass processed from the molten state into
fibrous form, bonded with an organic binder, and the orientation of the fibers within the roll or sheet insulation is essentially
perpendicular to the heated or cooled surface (parallel to heat flow).
6.2 Facings:
6.2.1 The purchaser must specify the insulation facing and type required. (CAUTION:Warning—The user is advised that the
maximum use temperature of the facings and adhesives may be lower than the maximum use temperature of the insulation. The
specifier shall ensure that sufficient insulation thickness is installed so none of the accessory items (facing and adhesive) are
exposed to temperatures above their maximum use temperature. Practice C 680 can be used to predict surface temperatures.)
6.2.2 Typical Facings:
6.2.2.1 Fiber glass nonreinforced mat.
6.2.2.2 Laminated aluminum foil, reinforced fiber glass scrim, and natural Kraft paper generally known as FRK or FSK.
6.2.2.3 Laminated white Kraft paper, reinforced fiber glass scrim, and aluminum foil generally known as ASJ (All Service
Jacket).
6.2.2.4 All vapor retarder facings shall comply with Specification C 1136.
6.2.2.5 Other kinds or compositions of facings may be specified.
6.3 Manufacturing/Fabrication—Mineral (rock, slag, or glass) fiberboard is normally manufactured with the fiber essentially
oriented parallel with the face or a facing. Fiber direction described in this specification is substantially perpendicular to a facing.
This construction aligns mineral fiberboard in a way that one end of the cut fiber is adhered to a facing. The finished product is
wound into rolls or cut into sheets.
7. Physical Properties
7.1 The perpendicularly oriented mineral fiber roll and sheet thermal insulation shall conform to the following requirements in
Table 1: maximum use temperature, maximum apparent thermal conductivity, minimum compressive resistance, water vapor
sorption, maximum design density, and maximum indices for surface burning characteristics.
7.2 Corrosiveness to Steel—When tested in accordance with 11.6, the corrosion resulting from the insulation in contact with
steel plates shall be judged to be no greater than for comparative plates in contact with sterile cotton. (Caution:Warning—There
are facing adhesives that can cause corrosion to steel when they are in contact with water or water vapor and the steel. Currently,
there is no test method available to satisfy every potential corrosion application.)
7.3 Stress Corrosion to Austenitic Stainless Steel—When specified, shall be tested and evaluated in accordance with 11.9.
7.4 Non-fibrous Content (Shot) —The average maximum shot content of rock and slag mineral fiber products shall not exceed
30 % by weight in accordance with 11.3.1. Non-fibrous content is not applicable to glass mineral fiber products.
7.5 Maximum Use Temperature—Whentestedinaccordancewith11.1,theinsulationwithfacingshallnotwarp,flame,orglow
during hot surface exposure. No evidence of melting or fiber degradation shall be evident upon posttest inspection.
7.6 Maximum Exothermic Temperature Rise—When tested in accordance with 11.1, the midpoint temperature shall not at any
point in time exceed the hot surface temperature by more than 200°F (111°C). The 200°F criterion applies during heat up as well
as steady state conditions. Exceeding this limit shall constitute noncompliance to this specification and rejection.(Caution:
Warning—Organic binders, adhesives, and some facings may thermally decompose at high temperatures causing an exothermic
temperature rise to occur.Adouble-layered installation of perpendicularly oriented mineral fiber insulation and facing on surfaces
hotter than 450°F (232°C) may increase the possibility of internal exothermic temperature rise and may destroy the fiber.)
7.7 Compressive Resistance—Shall be tested in accordance with 11.8.
NOTE 1—At conditions above 450°F (232°C) hot surface temperatures, the compressive resistance of the installed insulation material may decrease.
Contact the manufacturer for reduced compression resistances at maximum temperature conditions.
