ones; for the FLEX devices of the F series and the FLEX device R1, they include the
nuts and washers M6, for FLEX R2, R3 and R4 M8. The M6 nuts must be tightened
using the tightening torque of 6 Nm, whereas the M8 nut with the tightening torque of
15 Nm.
In the event of explosion, FLEX must be inspected by the manufacturer or by the
trained person, so that the proper function for the further safe use is ensured.
7.2 FLEX SERVICE AFT ER EXPLOSION OR WHEN THE MEMBRANE IS DAM AGED
In the chapters below, the procedure for the FLEX service in the event of the explosion in the
protected technology or after the damage to the membrane is detailed.
7.2.1 FLEX SERVICE AFT ER E XPLOSION
In the event that the explosion occurs in the protected technology or the flame filter mesh is
heavily polluted with dust and other dirt, the following procedure of the flame filter
replacement must be observed. This procedure is different for individual types of FLEX.
FLEX, R-Series:
1) Stop the production process in the protected technology immediately.
2) Let FLEX and its surrounding cool down to the acceptable level, so that it is possible
to work in the vicinity of FLEX as well as with the actual device.
3) In the event of explosion, FLEX must be dismounted from the equipment.
4) After the dismounting, check whether no visible damage and plastic deformation to
the FLEX body and lid has occurred and whether its integrity is maintained. If not, the
further use of FLEX is prohibited!
5) Then disassemble the entire FLEX, remove the top cover and pull the flame filter out.
Remove the used membrane.
6) In two places in FLEX, in the vicinity of the flame filter, there are two ALSIFLEX 1430
(thick. 2) gaskets applied (see fig. 15). If these gaskets are not damaged or polluted
after the explosion, or if their integrity is not infringed, there is no need to change
them. Otherwise, replace them with the new ones.
7) This dismounted FLEX must be thoroughly cleaned and the residue materials after
the explosion must all be removed. During this cleaning, pay attention to the surfaces,
on which there is the gasket form the previous clause; it must not be damaged.
8) This cleaned FLEX can be further repaired and used. A new flame filter (a spare part
delivered by the supplier) should be inserted into the upper part of the frame, or the
gasket should be replaced and the FLEX lid should be tightened, using the original
