PE100 LU Welding sleeve 75 SDR11

This Wavin Monoline electrofusion coupling is used in water and gas systems to make a connection between two PE pipes or pressure fittings.

In addition to this electrofusion sleeve, the electrofusion coupling range includes various accessories, such as:

• Tools.
• Links.
• Welding machines.
• Gaskets.
• Transitions.

Properties

The Monoline electrofusion coupling has a maximum operating temperature of 20°C with a working pressure of 16 bar for water systems. For gas pipeline systems, the maximum operating temperature is 20°C with a working pressure of 10 bar.

Quality mark

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

Assembly

This coupling is used to connect two pipes or fittings. To weld a PE pressure pipe to a weld coupling, you 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 sleeve on the pipe and mark the spot with a marker.
• Remove the sleeve from the pipe, use the peeling device and remove the burrs.
• Clean the area with PE cleaner and, if necessary, re-indicate the length.
• Replace the sleeve around the pipe 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.
