Kähler Hot Tapping Technology

Say goodbye to outdated, time- and energy-consuming methods of network expansion.
Kähler Industrie-Armaturen offers you a hot tapping technique that saves time, resources and your nerves.

What does hot tapping technology involve?

Our hot tapping technology includes all the technical equipment required for hot tapping during operation. In addition to the hot tapping machine as the heart of the hot tapping system, this includes suitable hot tapping ball valves in various nominal sizes as well as a wide range of accessories and consumables.

The hot tapping process was developed to connect new consumers to existing pipeline systems, such as heating, cooling and industrial systems, under full pressure and at full operating temperature without interrupting the supply to existing consumers.

During hot tapping, the pressurized pipeline is drilled through a pre-welded hot tapping ball valve using a special tapping tool, thus creating a new connection. A detailed description of the tapping method can be found here.

Compared to conventional methods, which require the existing pipe networks to be shut down, drained and (re)filled, this innovative process offers decisive advantages:

Of course, all equipment and processes used have the necessary approvals. Our hot tapping process is regularly tested and certified by recognized experts in accordance with AGFW guidelines. The hot tapping tool itself has a TÜV component mark.

As a specialist in industrial valves and an experienced company with many years of expertise in the field of hot tapping technology, we at Kähler Industrie-Armaturen work closely with our Finnish partner Vexve, the world's leading provider of valve solutions and developer of the NAVAL hot tapping system.
