Gate Valves and Pigging
Gate Valves and Pigging
(OP)
Are all gate valves used in the Petroleum Industry capable of being pigged, particulaler with an intelligent pig?
What should I be looking for to determine if my existing gate valves are suitable for pigging?

RE: Gate Valves and Pigging
One caveat, when people back a valve off the back seat they sometimes get too enthusiastic, and sometimes people get trash on the stem and think the valve is open when it is partially closed. Neither of these problems result in a measurable pressure drop across a gate valve, but they are both really hard on a smart pig.
