Knauf Pipe & Tank Insulation

pipe and tank insulation

Description

Knauf Pipe and Tank Insulation is a semi-rigid fiber glass board in roll form faced with a factory-applied FSK or ASJ vapor retarder, or a glass mat facing. The glass fibers are adhered perpendicular to the jacketing for flexibility and easy installation.

Application

Knauf Pipe and Tank Insulation is typically used on tanks, vessels and large-diameter pipes. It can be used for any curved or irregular surfaces that require finished characteristics of rigid fiber glass insulation.

Application & Specification Guidelines

Precautions

  • ASJ and FSK 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.

Preparation

  • Apply the product on clean, dry surfaces.

Application

For easy installation of Knauf Pipe and Tank Insulation simply follow these guidelines.

  • Refer to the Stretch-out Chart (below) to find the appropriate length to cut for the specific pipe size. Be sure to add an additional 2" (51 mm) to 4" (102 mm) for your staple flap.
  • Cut your stretch-out length and wrap the material around the iron pipe to ensure the proper fit.
  • Staple the lap on 3" (76 mm) centers with outward clinching staples.
  • Butt edges shall be firmly secured, and butt strips matching the jacket shall be applied at each joint.
