Description

Description

Pipe Wraps comprise layers of a graphite-based intumescent sheet encapsulated in a polythene sheath. The product is designed to be wrapped around the outside diameter of the pipework or trunking and is secured by means of a self-adhesive strip. The Intumescent Pipe Wrap is then positioned within the compartment wall or floor so that the edge of the product is left exposed at the face of the wall or soffit. The Intumescent Pipe wrap is then sealed into the structure with Firestop motor/compound. Under fire conditions, the intumescent material expands against the structure and fills the void left by the burnt out plastic pipe. For walls it may be necessary to fit two wraps depending on the fire risk areas concerned and if the wall thickness exceeds 150mm.

Installation

Installation in Floors

  1. Check that pipe surface is clear of mortar or any other contaminants.
  2. Remove any debris or dust within the hole.
  3. Ensure that the correct Pipe Wrap is installed to suit diameter of pipe and fire rating.
  4. Wrap around pipe and fix with integral self-adhesive strip.
  5. Slide the Pipe Wrap on top of the shuttering being used for the making good. Ensuring that the bottom edge of the wrap will be exposed in the floor slab when the shuttering is removed.
  6. Important: If you are using permanent mineral wool shuttering for Firestop Compound, cut out the shuttering to ensure that the bottom edge of the Pipe Wrap can be viewed from the soffit below. If this is not carried out the intumescent material will be insulated and shall lead to a product malfunction.
  7. Seal the Pipe Wrap into the structure with Firestop Compound or concrete, ensuring that there is a minimum of 25mm cover over the top of the Pipe Wrap.

Installation in Masonry Walls

  1. Check that pipe surface is clear of mortar or any other contaminants.
  2. Remove any debris or dust within the hole.
  3. Ensure that the correct Pipe Wrap is installed to suit diameter of pipe and fire rating.
  4. Wrap around pipe and fix with integral self-adhesive strip.
  5. Slide the Pipe Wrap into the wall, ensuring that the outermost edge of the wrap aligns with the face of the block work. Important: If this is not carried out, the intumescent material will be insulated and shall lead to a product malfunction.
  6. Repeat on the other side of the wall.
  7. Make good around Pipe Wrap with either Firestop Compound or traditional mortar to the full depth of the seal.
