The vent pipe is obsolete and the unique design increases the capacity of the riser. The Akavent aerator will be delivered with closed caps. After removing the caps, the required branches can be butt-welded to the aerator. When the connection will be made with snap socket Art. Nr. 40xx10a tight-fit plug-in connection is created. Then a transition to other material is also possible. HDPE...

Jointing methods Electrofusion, the most simple and rapid jointing technique, is mainly used on construction sites for a highly efficient method of assembly for pipes, fittings and prefabricated sections. Electrofusion couplers The PE range includes couplers in the diameters 40 to 315 mm. The couplers are extremely suitable for applications in waste water and rainwater drainage, with the following features: 1. Injection molded with excellent dimensional accuracy and stability. 2. One welding indicator on each welding surface for checking both welding connections. 3. Centre stops easy to remove...

Jointing methods Welding process The butt-welding of Akatherm HDPE operates according to the following Both sides should be machined until they run parallel. When the machining is finished, open the carriages (the plastic shavings must be continuous and uniform in both sides to weld). Take off the milling cutter. Verify the alignment between the machined surfaces. Remove the plastic shaving. Do not dirty or touch the machined surfaces. machining cutter clamps welding machine Preheating under pressure Press the two ends to be jointed gradually to the heating element until a bead is created. The...

Jointing methods Evaluating the butt-weld joint The butt-weld can be evaluated using destructive and non destructive evaluation methods. For these evaluations special equipment has to be used. Butt-welds can easily be judged by a visual inspection making this the recommended method for a first evaluation. The shape of the welding bead is an indication for the proper operation of the welding process. Both welding beads should have the same shape and size. The width of the welding bead should approximately be 0.5 x the height. Differences between the beads can be caused by the difference in HDPE...
