Electrofusion fitting

special system Raufrigo-FW for heating installations with integrated Rautherm- FW basis pipes. Rehau’s basic idea of a fully polymer system is pursued by the extension of the range of fittings of Fusapex. The new Fusapex reducing adapters and flange connections are made of PE-Xa and can be used universally with all Fusapex fittings with integrated heater coils. The new Fusapex flange connections made of PE-Xa are chamfered on the inside of the flange and therefore allow unproblematic opening and closing of commercially available flange-connected flaps. There is no need for special flaps for pipes made of polymer material. The integrated lapped flange facilitates the installation and cannot be forgotten. The new flow-optimised reducing adapters made of PE-Xa are available in every combination in a dimensional range of 75 to 160mm. On account of the compact construction, every dimensional reduction can be set up depending on the site’s requirement, even in a very small space. Fusapex fittings in the dimensions 50 and 63mm have been added to the range. In addition, Rehau offers a suitable welding tool for uncomplicated processing.

A system is only as good as its weakest component part. In pipe systems, this weak point is the joint, as a rule. Pipe systems from Rehau aim to break that rule. Apart from the permanently tight compression sleeve jointing technique, the polymer processor offers in its range the temperature-resistant Fusapex electrofusion fitting, a jointing technique designed for district heating and industrial pipe systems.

heating supply systems, in heating installations or in the transport of thermal waters, chemicals as well as hot aggressive media. It can be employed up to temperatures of 95ºC and ensures absolutely tight joints. Together with the pipe systems for district heating (Rauthermex or Rauvitherm), for industrial heating (Rautherm-FM) and for chemicals, water, compressed air or inert gases (Raupex), it produces a fully polymer and thus corrosion-resistant system. In addition, the Fusapex jointing technique can be used in the
