Black Couplers / EF / PN20 / SDR9
Black Couplers / MB-UB / PN20 / SDR 9
The Frialen PE100 SDR9 black coupler range is made up of a combination of MB and UB style couplers.
MB & UB couplers feature large insertion depths for pipe stability during fusion (no holding clamps required) and extra-wide fusion and cold zones for maximum melt containment. All couplers feature exposed heating coils for direct heat transmission to the pipe and a machined internal bore to ensure optimum joining pressure in the fusion zone.
UB SDR9 couplers dn280 and above include a barcode PREHEAT function to warm the pipe and coupler before fusion. Preheat assists in closing the fusion gap between the pipe and coupler prior to welding. Couplers dn280 and above feature 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. Frialen UB SDR9 Electrofusion couplers are made in Germany.
| MB couplers ≤ dn63 and SDR9 Couplers dn90 to dn355 are fully rated for PN25 / SDR7.4 and can be used for PN20 applications. | |||||||
