Webb1 okt. 2024 · While the thermal growth or contraction of the pipe segment may only be a small fraction of an inch, the force required to resist the force generated by the expansion can be tens of thousands of pounds. Allowing the pump to float by a 1/16 th of an inch can reduce the reaction to a negligible level. Webb20 juli 2024 · What causes thermal expansion in piping? All piping materials expand or contract when exposed to temperatures greater or lower than the installation temperature. As the temperature of the pipe material increases due to fluid temperature or sun/flare radiation, the pipe expands. Again, pipes contract as temperature decreases.
