AXIAL GROWTH A037
Metal expands with an increase in temperature, and shrinks with a decrease in temperature.
A rule of thumb states that a stainless steel shaft will expand or contract 0.001 inch per inch of shaft length or diameter, for each 100°F change in temperature (0,001 millimeter per millimeter of shaft for each 50°C change in temperature).
Axial growth will affect both the open impeller to volute clearance setting and the mechanical seal face loading.
