As a pigging contractor we have a number of ways to determine cleanliness. This is established with a uniform pressure profile, zero coke returns, minimal discloration of water, condition of pigg, & condition of final sponge. There is a differential on these signals if the heater is Plug header or u bend configuration. Are you experiencing issues on this once pigging has been completed?
