Knauf KwikFlex Pipe & Tank
Description
Knauf KwikFlex Pipe and Tank Insulation is a 48" wide
semi-rigid fiber glass blanket, 2.5 pcf. density, in roll form. It
is available faced with a factory-applied ASJ, FSK or PSK vapor
retarder jacket. The fiber orientation provides excellent
compressive strength while maintaining flexibility for ease of
installation.
Application
Knauf KwikFlex Pipe and Tank Insulation is typically used on
tanks, vessels and large-diameter (greater than 10") pipes. It can
be used for any curved or irregular surfaces that require finished
characteristics of rigid fiber glass insulation.
Features and Beneftis
Excellent Thermal Properties
- Low thermal conductivity ratings to 850°F (454°C).
Low-Cost Installation
- Flexible.
- Easy to handle and fabricate.
Inventory Savings
- No need to stock multiple sizes.
- Various thicknesses available to meet all your pipe and tank
insulation needs.
Resists Damage
- Tough and durable.
- Resists damage in shipment and during and after
installation.
Resists Microbial Growth
- Does not promote the growth of fungi or bacteria.
- Will not rot or sustain vermin.
Non-Corrosive
- Will not accelerate corrosion of aluminum, steel or
copper.
Specification Compliance
- UL/ULC Classified
- ASTM C 1393
- Types I, II, IIIA, IIIB Category
- ASTM C 795
- NRC Reg. Guide 1.36
- MIL-I-24244
Technical Data
Temperature Range (ASTM C 411)
- Operating Temperature to 850°F (454°C).
Compressive Strength (ASTM C 165)
- Not less than 25 PSF (1.2 kPa) at 10% deformation.
Water Vapor Transmission (ASTM E 96, Procedure A)
- FSK, ASJ and PSK vapor retarders have a maximum water vapor
transmission rate of .02 perms.
Puncture Resistance (TAPPI Test T803) (Beach Units)
- FSK and PSK facings: 25
- ASJ facing: 50
Surface Burning Characteristics
- UL/ULC Classified (FSK, ASJ).
- Does not exceed 25 Flame Spread, 50 Smoke Developed when tested
according to ASTM E 84 and UL 723.
Linear Shrinkage (ASTM C 356)
Precautions
- ASJ, FSK and PSK jackets should not be used if outer-surface
temperature exceeds 150°F (66°C).
- During initial heat-up to operating temperatures above 350°F
(177°C), a slight odor and some smoke may be given off as a portion
of the bonding material used in the insulation begins to undergo
and controlled decomposition.
- If natural convection is not adequate in confined areas, forced
ventilation should be provided in order to protect against any
harmful fumes and vapors that might be generated.
- Care must also be taken when using sealants, solvents, or
flammable adhesive during installation.
Storage
- Protect stored insulation from water damage and other
abuse.
- Protect from welding sparks and open flame.
- Cartons are not designed for outside storage.
