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.
The balloons come in four sizes, suited for different pipe dimension. The balloons and tooling are colour coded to help select correct dimensions.
When the work is done, the balloon is removed and a sealed cap is mounted to the clamp.
See Quick work instruction pdf or NoTap pipe blocking Flash video for further instructions. |

Pipe blocking |
|
|
Pipe blocking on pipe sizes:
14-23 mm, 26-34 mm
35-49 mm, 50- 60.3 mm |
The clamp with a non-return valve is used for smaller branch connections, installing an immersion pipe adapter and for pipe blocking. |
Special tools are required for working with the NoTap method |
|
Below you will find blocking kits needed for different pipe dimensions. Use the heading for the correct dimension interval of pipe to be blocked. Go down to the list and find the exact dimension and article description that is needed for the blocking. |
