Extreme Pipeline Connection While Pipes Still in Service: Hot Tapping With TONISCO Valves
Video featuring the DN 300 TONISCO Hot tapping valves during a Hot Tapping process carried out by Tonisco System team.
TONISCO System is a nearly 50 year old Finnish company present in 20 countries and is specialized in hot tapping processes.
Hot tapping is the method of making a connection to existing piping or pressure vessels without the interruption of emptying that section of pipe or vessel.

Can really do without the music.
Clever, and I agree with avalon449. nix on the muzak.
well that was cool! or should I say hot?
That welding at the end didn't look too good..
Would have been nicer to have other languages in the descriptions. Didn't understand what was going on.
My first thought.. where did all of the metal chips go? It looks like they would fall into the service line being drilled
just with real sounds next time please
Ok….tone down the music tough guy….
I have made many Hop Taps with a Muller 900 machine. The Muller extracts the plug that was cut to make the Tap!
This is a water main?
I take it you folks don't get real winter…
Pretty cool job either way.
I don't care what these farts say,, I liked this video!! Very clever !
Ich mag das Lied. Was ist der Name dieses Lied? Es ist kool und super. Gut für tanzen.
try that 300 ft underwater like we do in the offshore oil industry
who had the balls to weld that flange?
In the US we drill through a gate valve. That way you can just close the valve after drilling the pipe.
Very badly presented. You had to guess what was going on.
12:54 pipe wrench vs screwdriver!!! Go home man!
1:48 ммм, nutella :))
That's badass. I have to laugh at some of the comments. If you don't like the music, just mute it haha. If you can't tell what they're doing, maybe you should look into it a bit more, instead of just complaining. There's way too many people that are oblivious to the rest of the internet, to them it's just Social Media and YouTube. They have no idea how to actually look something up, because they just wait for someone to do it for them.
Wonderful video.
I wouldn't have to contact you if you had a brain and put it in freaking English but I guess hey some people don't have a brain
very fantastic tehnology
Please turn the music UP AS LOUD AS IT CAN GO
I've welded about 7 of these big weldolets on in my day, they u.t. the main line first to see how thick it is. I made the welding inspector hang around while I first lit up on the pipe in case it was to blow….some of them took 8 hours to complete the weld…My asshole was so tight you couldn't shove a 3/32 rod in it.
We would first weld a flange to the weldolet ….roll those out…then weld the weldolet to the mainline then you Bolt on a gate valve, open it up, then Bolt on the hot tap machine and drill the plug out, pull the drill up and close the value….it was a lot easier process then you see here… alot simpler hot tap machine…I think the company was t.d.w……UA 342 welder here…. retired
It'easy….This is only a waterpipe.More simply is to install a by-pass on crude oil pipe.First
1-Clean the pipe Surface wiith glender machine and cup brush
2-Install a spool with flange.Welding.
3-Install gasket and valve.
4-Install top head machines
5-Open valve.
6- Start drilling operation
7-Close the valve when all operation are done.
8- Remove top head machine.
9-Non destructive controls(X ray/cobalto or other)on the spool welding if is request
10-install By pass Line or Tie-in line.
This operation are not allowed on gas line in service.
very good
what is the tonisco valves
very good maintenance operation
NICE
Do hot taps all the time on fuel lines the welds are x Ray these welds on the video looked rough
the welder needs a little more training in welding but its a water line!!!! soooo anything goes right!!!! lolzzzzz
That's way to complicated. Our taps mount directly to a valve. You drill your tap, withdraw your bit, close the valve, done. No uneccesarry welding and ratcheting unnecessary temporary gates in place.
Nice clean job.
H.D.P.E Kapprør (outer pipe), with P.U. (Polyol/Isocyanat mix) foam insulation, appears to be a Fjernvarme (district heating) main line-linetap, since there's 2 pipes side by side (forward and return lines), on a 604 pipebranch, ok writing as I view it is district heating I see, the compensater is a type we used to use. One thing puzzles me a bit, we used to use Cyclopentan as a drivegas to inject the P.U., it is Megggggga inflamable!
The flame from the weld is close to the foam, I always thought an extinguisher was needed nearby, as if the P.U. burns the Cyclopentan would ignite, and the P.U. is Highly-toxic if it burns. hmmm. Nice job people, better safety is needed though, a few unsafe practices I see done.
Really interesting how they tap into "hot" pipe like this. It's not like you have the luxury to shut off a main water (?) line so you can connect to this. Some crazy engineering to solve this dilemma.
ever heard of a ratchet and socket
Fuck your music.
Just not slow enough.
