In general, we do not recommend intumescent pipe collars as a firestopping barrier around metal pipework. When heated, fire pipe collars expand to seal any gaps surrounding pipework as it penetrates through walls, partitions, ceilings and flooring. Metal is not as flexible as plastic pipework, therefore it’s not guaranteed that our fire collars can crush the metal pipe and completely block fire from spreading.
