Buttwelding is a very economical and reliable jointing technique for making permanently welded joints, requiring only buttwelding equipment.
Buttwelding is particularly suitable for prefabricating pipe sections and special fittings. Both Akatherm fittings with short spigot end and fittings with long spigot end are suitable for buttwelding.
Only pipes and fitting from the same wall thickness series can be butt-welded together.
Electrofusion is a simple and rapid jointing technique for making permanently welded joints.
The efficient assembly on-site of pipes, fittings of prefabricated pipework can be achieved using electrofusion couplers and electrofusion welding equipment.
Only fittings with long spigot ends are suitable for electrofusion.
