Three Pipe Tapping Methods

- You have a water distribution system in place; how do you tap a pipe to add new lines without interrupting service to critical facilities?
Three common pipe tapping methods in the water and wastewater industry allow a pipeline to continue operating while maintenance or modifications are being done. In this video, Jerry Regula and Josh Baker from McWane Ductile discuss the advantages and disadvantages of Direct Taps, Tapping Saddles, and Tapping Sleeves in Ductile iron pipe and alternate materials. They consider key factors when selecting a tapping method, such as the pipeline's age, project specifications, safety requirements, and the tools needed to get the job done.
Then Josh joins the West Wilson Utility District team in Mt. Juliet, Tennessee, to demonstrate each tapping method. You'll get a detailed look at the process alongside a professional crew that has performed hundreds of taps in the field.
Special thanks to Jeremy Ash, Jason Ash, Richard Todd, and Wesley White for sharing your skill and experience. And thank you to Freddie Weston, Kelly Cook, and all the people at West Wilson Utility District for your time and effort in completing this project.

This is so cool. I’m going for a distribution job soon and I love to be prepared so thank you!
You are so welcome! Good luck with the job.
This was a great videos guys. Great Job
Glad you enjoyed it! Thanks for watching.
thank you for a good information and video
Glad it was helpful. Stay tuned for more.
Great tutorials!
Glad you like them! Thanks.
On a ~6" pipe like that, do you have any trouble with the pipe threads sealing up on a direct tap. It's only like 0.25" wall thickness. Seems like you wouldn't have much thread engagement for a seal.
Thanks for your question. DIPRA (the Ductile Iron Pipe Research Assoc, dipra.org) has done three studies of this exact question, in 1976, 1987 and most recently in 1999. They released a paper called "Direct Tapping of 6-inch Pressure Class 350 Ductile Iron Pipe" with a detailed explanation of their testing process and lots of great photos. To quote their study, "...3/4-inch and 1-inch corporations tapped into 6-inch diameter Pressure Class 350 Ductile Iron Pipe is more than adequate to effect a structurally secure, watertight seal." They recommend using two layers of 3-mil thread sealant tape for a watertight connection. They also concluded, "Pull-out and cantilever forces, when sufficient, result in failure to the corporation stop, not the pipe or threads." We encourage you to read the entire study so you can learn the facts about #IronStrong DI pipe.
@@McWaneDuctilePipe Thanks for the great response!

You're welcome. Thanks for watching. Please subscribe and check out our other videos.
Make sure line is clean
Indeed. Thanks for the comment.
I find going to the line, the diameter of the threaded hole is always too big for the corp. so I stay an 1/8 to 3/16 off the line.
Thanks for sharing your experience.
I noticed there was no cutting grease used
That is correct. Cutting grease is not required.
Its a dry tap....
Indeed. As opposed to a Wet Tap where the pipe is in use and full of water.
Come on guys we believe you just don’t have to wear the hardhat
