Hydra-Core - Pipe Wall Sampling Kit

Fact 1: The inner diameter of a pipe cannot be determined by simply looking at the pipe.

Fact 2: The inner diameter of the same type and nominal size of pipe can vary from manufacturer to manufacturer and from production run to production run.

The puzzling question of “What’s the inner pipe diameter?” often results in an unsettling silence. Inconsistencies found in the inner diameter of some types of pipe — due to manufacturing variances, date of manufacture, material used and more — reveal the importance of knowing not just the outer diameter but also the inner diameter of the pipe where you are planning to install an Insta-Valve 250 Patriot insertion valve.

Knowing the inner diameter of the host pipe permits precision fitting of both the cutter and the Insta-Valve 250 Patriot valve cartridge to be used. Having this information on hand allows for the best possible Insta-Valve 250 Patriot insertion valve shutdown.

At this point, you may be asking, “How can I take a core sample and still proceed with an IV 250 Patriot installation?”

Eliminate the guesswork when it comes to inner diameter. The Hydra-Core sampling process consists of a few simple steps, and takes just a few minutes:

1. Set up the Hydra-Tapper machine with the Hydra-Core sampling cutter.
2. Make the core sample tap.
3. Utilizing a simple formula, determine the pipe’s inner diameter, cutter size and cartridge size.
4. Tap using the core sampling centering tool.
5. Proceed with valve installation.
