Question

If additional valves are used, the highest pressure setting shall not exceed the M.A.W.P. by more than:

a) 3%
b) 4%
c) 5%
d) 6%

Answer 1

b) 4%. If additional valves are used, the highest pressure setting shall not exceed the M.A.W.P. by more than 4%.

Step-by-step explanation:

When using additional valves, the highest pressure setting should not exceed the Maximum Allowable Working Pressure (M.A.W.P) by more than 4%. This ensures that the pressure remains within a safe limit and prevents any potential damage or failure.
