Hot-tap activity

[migueldiazch]

We are planning to perform a double hot-tap and stopple on 10" pipe SCH STD with AGO as a process fluid from a distillation tower. The pressure for the process is 54 psi and the temperature is 440°F. The hot-tap company asked us for a maximun velocity through the pipe of 4 feet/sec. We have an internal document called Guidelines for Hot-tap and it is recommended a velocity not greater than 6 ft/sec. Can anybody tell me why we should control the process fluid velocity and what could be the consequences of not doing that?

Best regards,
M.D

As you can see from the video the process is rather straight forward; I believe the velocity requirement is to prevent the posssibility of loss of cut out pieces.
