RE: Pig Stuck by Hot-Tapping
Issues can be - incorrect or no inclusion of bars in the hot tap allowing the pig to divert and get stuck
Machining debris or even the coupon if it fell off the drilling machine.
Solutions? De-pressure / drain the pipeline, take the valve off and have a look!
first try and find your pig.
you're not giving much away in your post so it's difficult to add much more. Search "stuck pig" on this site and there are many other discussions, all end up with the fact that this is an operational catastrophe and is rarely solved by anything other than venting / draining and cutting the pipe to remove it.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
