From d 280 with preheating bar code to compensate for a larger annular gap.

FRIALEN safety fittings UB SDR 7.4 can be fused with SDR level 7.4-11 pipes. Other levels of SDR can be processed on request.

Please note the mandatory labels directly on the product.

Areas of Application

The FRIALEN-Couplers UB SDR 7.4 and UB SDR 9 are used for pipe connections when laying long runs. Additional areas of application:

Integration of adapters into an existing pipeline
Connection of pipelines with fixed or restraint points

Assembly Instructions

The fusion of pipe ends with the FRIALEN-Coupler UB SDR 7.4 or UB SDR 9 takes place using FRIALEN-fusing – leakproof and longitudinally strong.

The pipe ends are prepared according to the general installation instructions (see “Assembly Instructions” for “FRIALEN-Safety Fittings for house connections and distribution pipes up to d 225” and “FRIALEN-Special Technology for laying large pipes and relining pipe networks”). This involves removing the oxide skin and cleaning the pipe ends. Please note that spigot of valves must be at least half as long as the coupler.

For removal of the oxide layer, FWSG scraper tools are available which facilitate a uniform swarf removal and a reproducible quality of the fusion area preparation.

To compensate a larger annular gap (> 1 mm, max.

3 mm) between coupler and pipe, the pre-heating barcode can be used for couplers UB SDR 7.4, d 280 - d 355 and couplers SDR 9, d 400 - d 630 (see instructions packed up with the coupler).

Good reasons for using the FRIALEN-Slide-over Coupler SDR 7.4 or SDR 9:
