NoTap method

The NoTap method can be used for hot water, fresh (tap) water, compressed air and refrigerants (glycol and salt based solutions). It is suitable for all pipes of metal, for example: black, painted, galvanised, stainless as well as copper. Valid for both thin-walled and annealed tempered pipe. Blockings can be carried out on pipes up to DN50 (2") and connections up to DN300 (12").

Do pipe work on pressurized lines quickly and easily with NoTap. Experience some of the many great advantages. Here is a taste of 10 of them.

10 good reasons to use NoTap
  • No need to drain the system
  • No refilling or venting the system after work is completed
  • Easy installation as no soldering, cutting or welding is necessary
  • Can be used on all types of metal piping: black steel, painted steel, galvanised, stainless and even copper
  • Saves energy, as no hot water needs to be drained
  • Can be used for hot water, fresh water, compressed air and refrigerants (glycol and salt based solutions)
  • Eliminates problems associated with the use of heating equipment, such as welding, soldering, etc.
  • Less corrosion in the system as no fresh, oxygen-rich water is added
  • Method is environmentally friendly, as no hazardous water needs to be drained
  • No fragments from drilling operations will enter into the system

NoTap® branch connections

Branch connections on pressurized water or air pipe systems, sometimes referred to as hot taps, are done with ease using NoTap.

Features 

The part that is mounted on the pipe is called a clamp. After the clamp has been tightened to the pipe, a special bore tool is used to allow work to be carried out while the pipe is still under pressure. This eliminates the need to shut off or drain the system.

The NoTap clamp is available in two versions: with or without a non-return valve. The clamp with a non-return valve is used for smaller branch connections, installing an immersion pipe adapter and for blocking. The clamp without a non-return valve is used on branch connections where you want to maintain maximum flow. These clamps come in even larger dimensions than those with non-return valves.

Technical Data 

The clamp with a non-return valve is used for smaller branch connections (14-125 mm), installing an immersion pipe adapter and for pipe blocking.

The clamp without a non-return valve is used when larger branch dimensions (26-335 mm) are desired for maximum flow from the branch connection.

NoTap® - Pipe blocking

Blocking is done by inserting a balloon into a pipe and blowing it up. In order to insert the balloon, a clamp must be mounted and a hole must be drilled into the pipe.

Features

The balloons come in four sizes, suited for different pipe dimensions. The balloons and tooling are color-coded to help select correct dimensions.

When the work is done, the balloon is removed and a sealed cap is mounted to the clamp.

NoTap® - Adapter for immersion pipe

Can be mounted on pipes with diameter 26-125 mm. Thermometer, length of 63 mm, suitable for pipes DN20- DN100. Thermometer, length of 100 mm, suitable for pipes DN65 – DN100.

Features

The immersion pipe adapter allows you to fit a thermometer or other measuring device on pressurized pipes. The system does not need to be shut down or drained. The immersion pipe adapter is fitted to a clamp with a non-return valve and then the measuring device is inserted into the pipe.

The immersion pipe adapter is suitable for thermometers with Ø 8.5 mm and 10 mm respectively. Two alternative gaskets (seals) are included that seal to the clamp. The measuring device threading should be sealed to the clamp with thread sealing.
