What is the maximum pressure rating of the EWARP emergency repair patch?

• A. 150 psi
• B. 50 psi
• C. 100 psi
• D. 300 psi

Answer: (A)

The patch’s maximum pressure rating is the highest differential pressure it can safely seal. EWARP is a rapid, temporary fix for hull or piping leaks and is designed to withstand up to 150 psi. This rating is chosen to cover common emergency leak scenarios while avoiding overstressing the patch materials and adhesive. Patching at pressures higher than 150 psi risks failure, which is why options like 300 psi aren’t appropriate, and lower options such as 50 or 100 psi would not reflect the patch’s full capability. Remember, EWARP is a temporary repair and should be followed by a permanent fix according to safety procedures.
