Variable spring-can supports should be used in what type of piping?

• A. Piping that must be supported at all times during thermal expansion and contraction
• B. Piping in continuous heavy load service
• C. Piping in non-thermal environments only
• D. Piping with units of measurement

Answer: (A)

Variable spring-can supports are designed to carry piping while accommodating thermal movement. Their built‑in spring mechanism takes up expansion and contraction so the pipe remains supported at all temperatures, preventing binding, sagging, or excessive stress on anchors. This makes them ideal for runs where the pipe must stay supported as it expands and contracts with temperature changes. They’re not chosen specifically for continuous heavy-load service, nor are they limited to non-thermal environments or tied to measurement units, so those contexts don’t align with the function of these supports.
