$$S_L \leq S_h$$ (Calculated Stress must be less than Hot Allowable Stress)

Piping stress analysis is the engineering discipline that provides the necessary technique to design systems without overstressing or overloading components and connected equipment. The primary objective is to prevent five major failures:

[Anchor] ─── (Restrained Point) ─── No Movement / No Rotation [Guide] ─── (Linear Direction) ─── Allows Axial / Restrains Lateral [Rest] ─── (Gravity Support) ─── Takes Weight / Allows Axial & Lateral Weight Supports
