The ease of
maintenance feature involves the ability to remove the seal,
which is supported within a special retaining element, and replace
it without fully disconnecting or moving the mating flange or
runs of pipework as is typically the case with the standard DIN
and CETOP flanges found in heavy pipework systems.
There are no
comparable products at the high flow end of the range. The flange
design has considerable commercial potential in areas where the
cost of downtime is very high, such as in offshore industry.
The flange can be supplied in any steels
to suit the environment including 080M15 (standard), stainless
or exotic alloys.
As an alternative
to tightening the flanges using traditional studs and nuts they
can be supplied with a bolt tensioning system that utilizes a
hand operated jacking system which enable pre-tensioning of two
or more studs at one time, thus alleviating the need for large
torque wrenches, spanners etc. which become a big problem when
space is at a premium.
