LAuncher Receiver

LAuncher Receiver

LAuncher Receiver

(OP)
Hello,

Please can somebody explain me typical connection between launche/ receiver and pipe. Are pigging wye fittings best solution?

RE: LAuncher Receiver

A term often used is a barred tee.

RE: LAuncher Receiver

(OP)
I guess I wasnt clear in my question.

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?

RE: LAuncher Receiver

What size and pressure?

David

RE: LAuncher Receiver

Pressure 950psi; temperature 100F

RE: LAuncher Receiver

size 6" API 5L-X60

RE: LAuncher Receiver

Every "wye" valve I've ever seen has been low pressure.  

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.

David,

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.

RE: LAuncher Receiver

Google is a wonderful thing, but the market seems to be garden hoses and fire hoses.  The biggest I found was 2-1/2 inch.  The highest pressure was 300 psig.

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.
