FLANGING MACHINE
11
F-200
Pipes flanged by this method can be used in loose flange joints to replace lapped and
partly also cast pipe ends involving welding or soldering. The maximum dimensions of the
flange are the same as those of equivalent welded on lapped pipe ends.
Depending on the conditions of use, EN1092-1 standard or standard derived from this
can be used in dimensioning. The main factor, which defines the maximum diameter of
the flange, is deforming capability of material. In practice this capability is expressed as
elongation. This means that the proportion d4/OD should be smaller that the elongation
value of material to be flanged. However, the experimental results show that much
higher elongation values can be achieved thanks to the multidimensional straining
scheme.
In hot forming the sealing surface can be changed in quality from smooth to rough by
selecting the appropriate profile for the forming cone.
3.2 INFORMATION ON THE EQUIPMENT
Following equipment is available for th F-200 machine:
• Heating unit is an equipment used for heating the pipe to be flanged or otherwise
formed.
The heating unit enables the flanging of thick-walled pipes. The equipment
comprises an optional range of different heating nozzles, an infrared thermometer and an
automatic flame guard.
• Beveling unit
to be used for beveling the edge of the pipe end, to prepare it for
welding.
• Forming pin
. Different forming pins are available for forming a grooved flange and for
flanging stainless steel pipes. The standard forming pin delivered with the machine is for
use on normal steel pipes. For flaring not necessary to use grooved forming pin.
• Expansion pin
to expand the end of the pipe for a sleeve extension.
• Pipe gripping clamps
which can be ordered according to pipe diameter, available for
diameters from Ø21.3- Ø219.1mm.
• Digital measuring device for positioning of the forming pins.
Indicates the distance
from the surface of the forming pin to the center of the pipe clamp. Read the instructions
which are supplied with machine (as PDF on memory stick).
