4 Steps for Designing a Fire Sprinkler System to Allow Expansion and Contraction

Like other piping materials, BlazeMaster CPVC expands as temperatures rise and contracts as temperatures fall. That means that the pipe will get longer in warm temperatures and shorter when it’s colder, which creates stress on the pipe that can lead to premature reliability issues. For example, a pipe constrained at both ends will be stressed as it expands when temperatures rise. Eventually, the pipe may crack or break, creating a leak. Expansion and contraction is mainly a concern in unconditioned spaces, such as attics. In conditioned spaces, there is minimal change in temperature and as a result little expansion and contraction. But it is important to keep expansion and contraction in mind when installing in very hot or cold weather before the HVAC system is operational. In these situations, there will be an initial expansion or contraction of the system.
