Quality mark

The Wavin 90° elbow is Kiwa and Gastec QA certified. This makes the electrofusion fitting suitable for drinking water and gas.

Assembly

This 90° elbow is used to connect two pipes or fittings. To weld a PE pressure pipe to a welded coupling, you'll need a PE cleaner, a peeling device, clamps, and a welding machine. During welding, the coil in the electrofusion fitting heats up, fusing the two components together. This creates a strong, tensile-resistant, gas-tight, and watertight connection.

The welding process

• Place the knee 90° to the pipe and mark the spot with a marker.
• Remove the elbow 90° from the pipe, use the peeling device and remove the burrs.
• Clean the area with PE cleaner and, if necessary, re-indicate the length.
• Reposition the knee 90° around the tube and tighten the screws.
• Connect the welding machine, scan the barcode and start the welding process.
• Check the indicator pins, they should have come out all the way.
• Disconnect and remove the welding cables and fixation clamps after the specified cooling time.
• Wait at least 2 hours before pressurizing the piping system.
