Internal design pressure creates circumferential (hoop) stress and longitudinal stress within the pipe wall. Secondary Loads (Displacement-Driven)
The weight of the pipe, valves, insulation, and the fluid inside.

Engineering Training Group Topic: Piping Flexibility, Primary & Secondary Stresses, and Layout Rules of Thumb If you'd like, I can: Explain the in detail
Always check your layout for adequate support and flexibility before finalizing. Next Lesson: Lesson 2 - Support Types and Selection. If you'd like, I can: Explain the in detail. Show you common mistakes that lead to piping failures. Provide a checklist for designing an expansion loop .
Designer creates the initial piping layout. they expand or contract.
High value is placed on honoring one's elders and maintaining family unity.
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.
