Pump casing distortion, leading to shaft misalignment, bearing failure, and mechanical seal leaks.
As pipes carry hot or cold fluids, they expand or contract. Without proper layout flexibility (such as expansion loops or offsets), this movement can exert massive forces on pump nozzles or vessel connections.

Thermal expansion is the primary cause of high stress in hot piping.
Evaluating pipe stress involves:
and understand essential terminology (such as thermal expansion and allowable pipe spans) to avoid common layout planning mistakes. Designer Responsibilities
