actually we will change valve on 14" pipe line.
space between header vessel and valve only 190 mm so i think we can not using hot tapping.
pipe freezing for 14" pipe i think is very expensive.
i see hot tap pipe plug is suitable for this application coz working pressure only 6 barg with fluid service is sea water.
could you please advise me the more suitable application for this?

Regards
EP

RE: Petersen« Hot Tap Pipe Plug Insertion Systems

You're not going to hot tap between the valve and the vessel.  Shut down the vessel.

Expensive is always a relative term.  Hot tapping and freezing have a cost, as does lost production.  The important thing is if the tap work, or freezing costs less than lost production do that, otherwise it is cheaper to shut down and unbolt/rebolt.
