FAQ - FRÄNKISCHE Rohrwerke

Q: Is it possible to install FBY pipes in concrete?

No. Here, clear standard-related statements concerning mechanical properties of the pipes are provided. According to IEC, only our FFKuS-EM-F, or products with similar or better properties can be used.

Q: Does the range of products by FRÄNKISCHE include an uncoil system for conduits?

No. To this end, high-quality products by Lübbering are available. www.luebbering.de

Q: What does "pliable, self recovering" stand for?

Pliable, self recovering pipes are classified 3 in the fifth digit, i. e. the pipes have a maximum deformation of 50% (based on the outside diameter). This permissible deformation reduces the inside diameter by 72%, which means that the inside diameter of a size 25 pipe shrinks from 17.9 mm to 5.0 mm.

Q: What surfaces can the ReMo click rail be mounted on?

The surface for mounting should be dry and dust-free. The temperature should be between 18 °C and 35 °C. The rail has an immediate holding force, its adhesive force, however, is not designed for continuous loads.

Q: Conduit installation in explosion hazard area, what conduit can be used here?

All steel and metal conduits - these, however, must be included in the equipotential bonding. Straight length plastic conduits may not be used

Q: Are there any standards/regulations stipulating that zero halogen installation must be ensured?

There are no normative specifications. The areas are determined by architects/designers.

Q: Where can I find fire safety assessments and installation instructions for FFKu-ReMo click?

For both downloads, please refer to the FFKu ReMo click product catalogue.

Q: How high is the conduit fill rate upon initial installation, for Kabuflex (30 %), for FFKuS-EM-F (60 %)? In which standard can I find it?

General recommendation is 30 %, though max. 50 % acc. to DIN VDE 0100-520, supplementary sheet 1, section 521.6.1 d).

Q: Up to what temperature can conduits (e.g. FFKuS-EM-F, FBY-EL-F) be installed?

All conduits of the FRÄNKISCHE product range have been tested according to DIN-EN 61386, and can be installed and used up to the temperatures specified in the data sheet, e.g. up to -25 °C for FFKuS-EM-F.

Q: Are there branches and/or reducers available for Kabuflex?

No, our range of products does not include branches or reducers for Kabuflex. Pull shafts can be used to branch out Kabuflex; for some nominal diameters it is sometimes also possible to use a branch from the Drainage area. This solution, however, is not technically intended.
