Effective fire stop solution for expanding pipework

The problem

Large pipework in the basement required supports allowing for expansion, as well as fire stopping of the pipe penetrations through firewalls to ensure the safety of fire escape routes. There were a number of different substrates and arrangements that required solutions, along with the added issue of pipe expansion and contraction. If pipe expansion and contraction are not correctly considered when installing a fire stop, the movement of the pipe could render the fire stop ineffective over time.

The Fire Stop Solution

Walraven’s range of fixing points and slide guides were ideal for fixing the large pipework system whilst allowing it to expand and contract. The Walraven Pacifyre® MKII Fire Sleeve was recommended for fire-stopping. It is unique in that it allows pipes to expand and contract without compromising the effectiveness of the fire-stopping – unlike fire collars which hold pipework static, preventing the pipe from expanding freely, potentially resulting in failure. Walraven provided technical advice, design solutions and on-site support for this project.
