Elbow with duck foot, SDR 11

Areas of Application

The FRIALEN-Elbow with Base Unit WF 90° allows for connection of a hydrant alongside the mains.

The hydrant connection takes place either

• by fusing the HD-PE pointed end of the hydrant with the construction part or
• for a hydrant with flange connection by applying the FRIALEN-Full Faced Flange EFL* or with a Flange Reduction FLR** d 110/DN 80.

Connection to the HD-PE mains takes place without pressure via the FRIALEN-Spigot Saddle SA d 110/90-225/110 (see Data Sheet No. 27 and leaflet) or under operating pressure with an additional cut-off device. For drilling into the mains we recommend drilling equipment by Hütz + Baumgarten.

Assembly Instructions

Please refer to the FRIALEN “Assembly Instructions” for preparations for the FRIALEN-fusion process (two fusion procedures) of the elbow piece with HD-PE pipes or HD-PE pipe and HD-PE valve (marking insertion depth, removing oxide skin, cleaning, etc.).

* (see Data Sheet EFL No. 46)

** (see Data Sheet FLR No. 61)

Good reasons for using the FRIALEN-Elbow with base unit WF 90°:

• Great wall thickness ensures optimum stability and safe positioning of the hydrant

• Separate fusion zones enable simple tension-free fusion

• Floor plate can be mounted directly onto foundations

• Base unit and elbow make up a homogeneous unit

• Large coupler depth for ease of guidance of pipe and construction part

• Small annular gap for build-up optimum joining pressure in the fusion zone

• Extra wide fusion zones

• Cold zones at the front side and in the middle of the coupler

• Exposed heating coil for optimum heat transfer onto pipe/construction part

• Additional barcode for tracing back the underground fitting (Traceability-Coding)
