Which patch holds 150 psi or less?

• A. Jubilee patch
• B. EWARP patch
• C. Elbow patch
• D. Banding patch

Answer: (D)

Patching a damaged pipe is all about matching the repair to the system’s pressure and the pipe’s geometry. The banding patch is a wrap-around repair that uses a metal band pressed over a patch disk to seal the hole. This simple, clamp-on concept works well for low-pressure situations and is specified to hold 150 psi or less, which is why it’s the right choice when the system is operating at or below that limit. The other patch types are designed for different conditions or higher pressures, such as shapes that fit around elbows or repairs that rely on epoxy or specialized clamps. Because those scenarios either require more robust sealing or a different fit, they aren’t the best fit for a 150 psi or lower situation.
