Piping is susceptible to the ambient temperature and the fluid temperature and varies in length due to expansion or compression.
Or, if a structure or building sinks on soft ground or its piping is subjected to external force, a tensile or compressive load is imposed on the piping.
Piping is not always in the same condition as described above, and it is, therefore, necessary in some situations to pay attention to various factors in designing piping. Expansion joints and displacement absorption joints are used to deal with changes in situations.
