I have two pipes which are running parallel. I would like to use one common launcher for both pipes. What kind of fitting I should use for this?

I really think you would be better off in a 6-inch to use something like an Argus Pigging Valve from Argus Machine Works in Calgary (http://www.argusmachine.com/pigging-valves.cfm). This gadget costs less than twice the cost of a ball valve and is a self-contained launcher or receiver. They make pigging valves up to 8-inch, but I don't like the cost or operation of the 8-inch. I like the 2-6 inch valves a lot.
Trying to divert pigs to one line or another is just full of risks at this pressure.

Do you know any manufacturer that produce 6" "wye" valves. I would like to look at their specs, so I can be able to explain concerns with providing common launcher for multiple piplines.
Thank you for your help.

If you were to find one big enough and strong enough for your application, I don't see how you would keep a pig from starting down the wrong leg and then tumbling (which tends to fold a foam pig so the sweep effeciency goes way down).
This just sounds like a bad idea.

Not sure how often or what type of pigging you plan to do, but if it is a requirement to have only one set of L/R's, , another potential option you might look at is one set of portable L/R's that you could set up on whichever line you want to pig.
