Banding patch hold: what is the maximum pressure it can safely contain?

• A. 100 psi or less
• B. 120 psi or less
• C. 140 psi or less
• D. 150 psi or less

Answer: (D)

Banding patches are rated by how much pressure they can reliably hold, which depends on the patch material, adhesive, and how well the patch is prepared and applied. The rating represents the pressure at which the patch would begin to fail, so the safe operating limit is the highest pressure the patch is rated to contain. For this item, the patch is specified to contain up to 150 psi, so the maximum safe containment is 150 psi or less. Exceeding that rating risks patch failure, leaks, or a blowout, so always stay within the patch’s listed rating and verify the rating from the patch documentation.
