Mobile demonstration unit

We have now introduced a mobile demonstration team to provide comprehensive practical experience and training of both NoTap™ ballooning and branching at our premises, your workshops and even worksites. We emphasise the demonstrations are part of our program to reinforce the confidence of operatives in using NoTap equipment and products

The demonstrations are without cost to yourselves and can contribute to the continuing professional development of your staff. They display how significant results are achieved with complete ease. The demonstations reveal the enormous potential NoTap™ kits have in cutting costs, saving energy and reducing downtime when modifying and repairing pressurised pipe installations. Should you wish to take advantage of our offer to see the team in action please contact us at the earliest opportunity to arrange the date, time and place.

Technical ingenuity

Drilling hole to ensure proper flow

Drilling hole to ensure proper flow

The first step in making your branch connection with NoTap™ is to choose a clamp with the desired size outlet. Clamps are available for pipes from 26 – 335 mm OD. The outlet size varies depending on pipe size. Outlets available are 1″, 11/2″, 2″ and 2 1/2″.

The NoTap™ method combines a centre drill bit with a hole saw. Once the centre drill bit penetrates the pipe, a flow will start to run through the tooling and out through the flushing device. This will ensure that chips and pipe shavings are carried away from the flow inside the pipe.

Next, the hole saw will start to cut through the pipe. The hole saw will cut through the pipe and also other layers of deposits that might be coated to the inside of the pipe. Using a hole saw will ensure that a proper hole is opened in the pipe for desired flow. The threaded centre drill bit drills itself into the portion of pipe that is cut out. This way the cut out portion of pipe is always retained (not lost in the pipe system).

When the hole saw has penetrated the pipe, simply retract (pull back) the drill until it stops. Then close the ball valve as shown in the picture. Finally, unscrew the drill housing from the ball valve and make the necessary branch connection.

When the job is finished, it is always a good idea to disassemble the NoTap™ tooling and dry it off for future use.

Clamps give flexibility

NoTap™ clamps can be used on all types of steel

NoTap Clamps can be used on all types of steel

K1 clamps are manufactured in brass, which means the same clamp can be installed on stainless steel, galvanised steel, mild steel, painted steel and even copper. The clamps can also be used on certain types of PVC plastic (ask the factory for more info.). Even NoTap™ big clamps can be used on these same materials due to the rubber seal, which acts as a barrier between the pipe and the clamp.

Odd pipe sizes? No problem with NoTap™!

Odd pipe size? No problem with NoTap!

NoTap™ is very often used for renovating or building onto to existing pipe systems. Many older pipes have odd pipe diameter dimensions. This is not a problem for NoTap as our unique clamp design allows each clamp to cover a dimension range.
