The fusiotherm®-pipe system made by aquatherm has proved its technical suitability in worldwide applications for 25 years and is highly recognized by experts as one of the most extensive and at the same time best plastic pipe system.
The program contains five different types of pipe - from cold water pipes to patented fibre-composite pipes with outside diameter from 16 mm to 315 mm. In addition there are over 400 joining and connection elements, referred to as fittings.
The Fusiotherm®-pipe system consists of:
- pipes in straight lengths and/or coils
- fittings
- flanged joints
- water point connections and accessories
- transition joints from PP-R to metal or from metal to PP-R
- weld in saddles
- distributors
- shut-off devices
- welding devices and machines
- cutting and peeling tools
- installation guide and fastenings
This wide range of pipes and fittings give ideal and adequate solutions for all fields of application. It also impresses due to its simple and effective connection technology: The result of the fusion of pipe and fitting is an inseperable material joining of the system components. Fusiotherm® is manufactured from polypropylene PP-R, a non-polluting and future-orientated material.
Welding connections for plastic pipes
In the field of plastic welding is a homogenous connection of two smilar materials. Two elements of the same material are connected directly - without adding any means of connection. The following fusion techniques are applied for hot and cold potable water supplies:
- Heating element socket welding
- Electrofusion socket welding
- Butt welding
Heating element socket welding
On heating element socket welding pipe and fittings are fused overlapping and without application of welding fillers. The heating element is necessary for heating the outer pipe and inner fitting diameter. The heating element socket welding can be carried out either with a welding machine or with a welding device. Two pipes are always connected with a fitting, like socket, elbow or tee. Fitting, pipe and heating tool must be coordinated in size by keeping the standard.
Electro-socket welding
The electro-fusion fittings, applied for electro socket welding, are equipped with integrated resistance wires, which are current-carrying during the fusion process. By this the inner diameter of the socket and the outer diameter of the pipe are heated up to welding temperature resulting in a melting mass on both parts. After their cooling there is an inseparable homogeneous connection. The necessary electrical energy is automatically supplied by suitable electro-fusion devices. Environmental influences are considered by the barcode and temperature compensation of the electro-fusion device.
Butt-welding
While heating element butt-welding the connection surfaces of the parts to be welded are levelled under pressure at the heating element, then heated up to welding temperature with reduced pressure and after removal of the heating element joint under pressure.
