Description

Intumescent Collar for Pipes and Other Services

A hinged, two-part metal pipe collar lined with intumescent material which expands in a fire. Features a quick-release pin, opening the unit for fitting around a wide variety of metal or plastic pipes as well as cables. An intumescent collar is either fitted or rebated into ceilings, floors or walls where services pass through. Cools down metal, steel and copper pipes, able to compartmentalise fires before they spread across buildings. The intumescent collar will crush plastic and PVC pipes in the event of a fire to prevent fire spread.

Our intumescent collars provide up to 4 hours of passive fire protection for industrial, commercial and other types of buildings. Currently installed in numerous Nuclear Power stations, as well as hospitals to provide passive fire protection. Supplied with brackets for ease of installation.

Available in various pipe sizes, up to 900mm diameter. Alternative versions with acoustic protection are also available. Where required, a fireproof sponge filler strip can be provided upon request for special applications.

Our electrical and plumbing products meet IET wiring regulations as well as Document B & E of Building Regulations tested to European and British Standards. Browse our full range of electrical and plumbing products.

Advantages

– Due to its heavy duty nature, it is a great fit for industrial buildings

– Provides up to 4 hours fire protection for pipes from 45mm-650mm in diameter

– Acoustic version offers both airborne and impact sound protection

– Adjustable brackets allow for fitting in hard-to-access areas

Application Instructions

Prior to fixing, please ensure:
● Access for fitting is available
● Correct area of risk is assessed (double-risk areas may require two collars
● Correct size of collar appropriate to the pipe or service being protected
(See also Envirograf® Product 110 for hollow wall fixing).
The product must be installed correctly. Fixing lugs are already fitted to WPCS
collars. They can be fixed to solid structures with raw plugs with screws. It is
recommended that you pump a spot of Envirograf product 58 (intumescent Mastic)
into the previously drilled hole. For hollow plasterboard walls, fix with screws if there
are timber noggins to fix to, otherwise use steel toggle fixings. If WPCS are to be
fitted into an area where no noggins or blockwork to attach to, the lugs can be
re-attached to another part of the WPCS by drilling 1.5mm holes into the side of the
collar and screw into collar. WPCS’s MUST be securely fixed.

Please Note: WPCS/C for ceiling application is only available from 2 hours protection upwards.

WPCS/C comes with hinge and pin opening.

l IMPORTANT

 

Please note that external pipe diameters may vary between different manufacturers and systems, and ambient temperature also affects dimensions. Please select the collar size most appropriate for your application, allowing a small clearance for ease of fitting. A close fitting between the collar and the pipe surface should be the aim, but the collar should not be unduly strained in order to close it around the pipe. A fireproof sponge filler strip can be provided upon request for special applications. Please enquire with details of your application for technical advice.
