Black Couplers / EF / PN16 / SDR11

Black Couplers / MB / PN16 / SDR11

Friatec's Frialen PE100 MB Injection moulded couplers are suitable for fusing pipes from SDR11 to SDR17.6  MB couplers feature large insertion depth for pipe stability during fusion (no holding clamps required) and extra wide fusion and cold zones for maximum melt containment. Exposed heating coils for direct heat transmission to the pipe and a small annular gap to ensure optimum joining pressure in the fusion zone.  A visual pop up fusion indicator confirms weld pressure and traceability bar codes are included for recording batch GIS and BIM records for each coupler installed.  All couplers are sealed in individual plastic bags for protection on site.

NOTE: The pipe or spigot ends and the coupler must be prepared in accordance with the general installation instructions using a spigot mechanical peeler, 90% Isopropyl alcohol wipes and we recommend using the Friamat fusion control unit to achieve correct preheating and logging the full range of weld data available.

Black Couplers / UB11 / PN16 / SDR11

Friatec's Frialen PE100 UB11 black couplers are suitable for fusing pipes from SDR11 to SDR17.6.  UB couplers feature large insertion depth for pipe stability during fusion (no holding clamps required) and extra-wide fusion and cold zones for maximum melt containment. Exposed heating coils for direct heat transmission to the pipe and a small annular gap to ensure optimum joining pressure in the fusion zone.  

UB11 coupler sizes dn ≥ 400 include a barcode PREHEAT function to warm the pipe and coupler to help re-round oval pipes and close the fusion gap prior to welding and permanent external reinforcement wound into the body of the coupler to ensure the coupler does not expand during the fusing process. 

Note: Couplers that are not injection moulded and do not have external reinforcement are likely to expand during fusion.  Coupler expansion increases the gap between the pipe and coupler, which reduces weld pressure in the joint. This leads to slow crack growth failure through the weld plane.  Slow Crack Growth, by its name, is slow and occurs over time (1-5 years), well beyond the joint successfully passing hydrostatic testing on site.

A visual pop up fusion indicator confirms weld pressure and traceability bar codes are included for recording batch GIS and BIM records for each coupler installed.  All couplers are sealed in individual plastic bags for protection on site.

NOTE: The pipe or spigot ends and the coupler must be prepared in accordance with the general installation instructions using a spigot mechanical peeler, 90% Isopropyl alcohol wipes and we recommend using the Friamat fusion control unit for logging the full range of weld data available.

Frialen UB11 Electrofusion couplers are made in Germany.
