Complete security, clear cost advantage

Our insulated flange connection combines maximum safety and tested standards with significant cost advantages over comparable systems.

Protection against corrosion and stray currents

Insulating flange from W2 – robust and durable

The Type 61 insulating flange connection is used as an electrical protection measure to reliably interrupt the metallic conductivity of a flange connection or a cathodic corrosion protection system (CCP system). It also provides reliable protection against bimetallic corrosion. The Type 61 is easy to install, maintenance-free, technically leak-proof and state-of-the-art.

Electrical separation

The insulating flange reliably interrupts electrical conductivity in the piping system, thereby protecting against dangerous equalising currents.

Corrosion protection

Effective protection against bimetal corrosion – for a longer service life of your equipment.

Tested and certified safety

CE mark in accordance with PED/DGRL 2014/68/EU and APZ 3.1 in accordance with DIN EN 10204
Complies with all relevant standards for safe operation.

Easy installation

Thanks to clear instructions and a complete scope of delivery, the insulating flange can be installed quickly and easily.

Maintenance-free operation

After installation, the insulating flange remains permanently functional – without any additional maintenance.

Flexibility

Whether standard, special flange, aggressive media or customised production – the type 61 insulating flange is available in numerous variants and can be adapted to suit your requirements.

Versions
