OPERATION MANUAL
4.4.2 PIPE FLARING
Always heed the following points when flaring a pipe:
1. The material quality of the pipe in process must be suitable for flaring. Recommended is seamless precision
steel pipe according to DIN 2391/C, material St.35.4 NBK, or use stainless steel pipes 1.4571 or 1.4541.
2. The pipe or tube must be cut at right angles. Face surfaces shall be lightly deburred from within and without.
3. The inner and outer surface of the pipe must be chip and grease free around the flaring die area.
4. Flaring cone and sliding surfaces of the flaring dies need a bit of grease now and then.
Attention: The roughened surface of the flaring dies must remain absolutely oil and grease free to prevent the
pipe from slipping through.
Working step sequence for flaring:
The attachment for pipe flaring is suspended in the universal basic adaptor. When hanging in the head,
please make sure that the carrier tappet of the piston rod extends into the internal groove of the flaring cone
seat.
Enter the flaring pressure at the control.
Spigot nut and sleeve are pushed onto the pipe before flaring. Make sure that the thinner part of the sleeve
is facing the spigot nut.
Insert the flaring jaw set corresponding with the pipe size into the device.
Push the pipe through the flaring die bore hole until it reaches the stop plate. Avoid canting of long pipes by
using a pipe support.
Press the push-button and hold it down until the flaring process switches off automatically. The red control
lamp goes out when the flaring pressure is reached.
Release the button – spring force pushes the flaring cone back into its original position.
In dangerous situations or when the machine does not switch off, please use the emergency-off switch.
