      I would suggest using the methods of ASME Code (Sec VIII Div 1, part UHX). Paragraph 13.5.5 provides methods to determine differential thermal expansion between tubes and shell. This is basically the same as TEMA standards section 7 T-4.5.
      If you simply wish to determine the thermal expansion of a single component, use alpha*delta T*L.
      alpha = coefficient of thermal expansion
      delta T = T(operating) - T(ambient)
      L = length considered for expansion

      I am unable to distribute copyright protected materials. If you are designing to another standard (PD550 or other), these should have similar sections.
