Which component is commonly used to adjust tension in pipe hangers?

• A. Turnbuckles
• B. Chains
• C. Clamps
• D. Nuts

Answer: (A)

Turnbuckles are designed to adjust tension by changing the distance between two threaded ends. In pipe hangers, a turnbuckle sits between parts of the hanger or between the hanger and the pipe, and rotating the central body shortens or lengthens the assembly. This lets you finely tune tension, level the pipe, and accommodate shifts from support movement or thermal expansion without loosening or over-stressing the system. Chains can be shortened or lengthened, but they don’t provide the precise, controllable tension adjustment that a turnbuckle offers. Clamps secure a pipe but don’t allow you to set tension. Nuts alone fasten connections and don’t deliver the adjustable tension needed in hangers.
