The main technology of joining PE-Xc and PE-RT pipes of the KAN-therm Press system is a press-assembly technology, where the steel ring is clamped on. To connect pipes to devices and armature you can also use clamped and screwed connections.
The „Press“ connecting technology consists in clamping around a pipe and connector a ring fitted on the connector stub pipe. The stub pipe is provided with an O-ring of synthetic EPDM rubber, resistant to high temperatures and pressures. The ring is clamped with a hand or electric clamping tool provided depending on the pipe diameter with “U”-profile jaws, or „C” or „TH-profile jaws (standard clamping tool). With this method of joining you can pass a system thru construction partitions (in a floor skim coat or embedded).
1. Cut a PE-Xc or PE-RT pipe at a straight angle to the axis to a required length with a scissors for plastic pipes.
2. Bend the pipe to a required shape. Bend with the help of an external or internal spring. Observe the minimum bending radius R > 5 OD. When you use a mechanical bender, for 14 – 20 mm diameters, the bending radius shall be R >3,5 OD.
3. Calibrate the pipe and chamfer its internal edge with a calibrating tool. The aluminium layer must be intact, without any unevenness or burrs. The pipe edge must be free any unevenness or burrs. In case of a connection with Press fittings this step may be omitted.
4. Push the pipe into a fitting till it stops. Check the depth a pipe is pushed into a fitting – the check hole must be fully hidden by the pipe.
5. Place the clamping tool jaws at the right angle on the steel ring but so it contacts the connector flange. The „U” -profile jaws shall not embrace the flange. In case of using the „TH“ clamping jaws the natural reference point for the tool is the fitting flange.
6. Start the press drive and make the connection. The process of clamping lasts until the tool jaws close fully. The ring may be clamped on a pipe only once.
7. Unlock the jaws and take the tool off the clamped ring. The connection is now ready for the pressure test.
