Με εξωτερική θερμαντική αντίσταση για ομοιόμορφη μεταφορά θερμότητας.
Με τεχνολογία προθέρμανσης d 400.
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.
With pre-heating technology from d 400.
Areas of Application
The FRIALEN-Coupler UB is used for cut and lay pipe connections.
Additional areas of application:
Integration of adapters into an existing pipeline
Connection of pipelines with fixed or restraint points
Reinforcement / sealing of localised pipe damage
Reinforcement of pinch points on small dimensions
Assembly Instructions
The fusion of pipe ends with the FRIALEN-Coupler UB 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 bore 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.
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 from d 400 (see instructions packed up with 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.
Good reasons for using the FRIALEN-Slide-over Coupler UB:
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
Touch proof electric contacts
Fusion indicators for visual fusion control
From d 400: pre-heating technique for a optimal gapbridging
From d 400: External reinforcement for an ideal fusion pressure
Durable batch marking
Individually wrapped for dirt protection
Additional barcode for tracing back the fitting (Traceability-Coding).
