FRIATEC FRIALEN - Couplers for Large Pipes (d 250 mm+); Cutting and Preparing Large Pipes

6
The design factor C (calculation coefficient for PE components) depends on
the area of application and the specifications (min. 1.25).
The parts are identified and usable with regard to their load-bearing
capability according to the above table.
DANGER !
Fusion with escaping media is not permissible.

4.1 Cutting to length of pipes
Cut off the pipe in a right angle
to the pipe axis (see Figure 1). A
suitable tool is a PE pipe cutter or a
saw with toothing suitable for
plastics.
Distinctive conical oblique pipeends
must be cut off, if necessary.
DANGER!
A non-rectangular pipe cutting
may cause the heating coil
partially not being covered by the
pipe which may result in
overheating, uncontrolled melt
formation or self-ignition (see
Figure 2).
