UB SDR 7,4

Ηλεκτροσύνδσμοι, SDR 7.4

Με εξωτερική θερμαντική αντίσταση για ομοιόμορφη μεταφορά θερμότητας, χωρίς την χρήση σφιγκτήρων συγκράτησης.

Διάμετρος d 280 και μεγαλύτερες με τεχνολογία προθέρμανσης (εναλλακτική χρήση).

With exposed heating coils for optimal heat transfer, large insertion depth, wide fusion zones plus cold zones at the end and in the middle to prevent the flow of molten material, for use without holding devices.

Diameter d 280 and bigger with pre-heating technology (optional use).

From d 280 with pre-heating barcode for compensation of a larger annular gap.

FRIALEN-Safety Fittings UB SDR 7.4 can be fused to pipes of SDR stages 7.4 to 11. Other SDR-stages on request.

Please observe the marking directly at the product, which is mandatory.

* according to EN 12007-2

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:

Large coupler depth for ease of pipe guiding (no holding clamps required)

Extra wide fusion zones

Maximum stability through great wall thickness

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

Exposed heating coil for direct heat transmission to the pipe

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

Contacts safe to touch

Fusion indicators for visual fusion control

From d 225: External reinforcement for an ideal fusion pressure

From d 280: unique pre-heating technique for a optimal gap-bridging

Durable batch marking

Individually wrapped for dirt protection

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