The highly flexible spinal hose between the inflatable
dams allows the PurgExtra® Systems to be pulled or
pushed easily around bends and elbows. In the centre
of the spinal hose a strip of RootGlo® material is
adhered, allowing the welder to see clearly through
the root gap, when the system has reached the
correct position in the pipe. RootGlo® can be charged
by exposing it to daylight for 10 minutes, after which
it will provide up to 24 hours of bright illumination
inside the pipe.
Heat Resistant Covers are also available for
PurgExtra®, which fit onto the inflatable dams and
allow operation with pre-heated and post-weld heat-
treated pipe joints where the temperatures might
reach 760°C.
The HFT® Weld Purge Monitors® are used to give
precise oxygen values throughout the purging
process.

The innovative PurgeGate® Valve may be fitted to the
PurgExtra® Systems as an accessory, to protect the
inflatable dams from bursting due to accidental over
pressurisation.
Xiris Releases Post Weld / Post Scarf
Weld Inspection for Tube Mills
To meet fabricators’ requests to implement
both a post-weld and post-scarf inspection on
a single mill, Xiris Automation Inc. is pleased
to announce that it has released a double head
version of its WI2000 Weld Inspection system:
one head can be placed immediately after the
weld box to detect weld related issues and one
head immediately after scarfing to detect scarf
related issues.
By placing the inspection system right after the
weld box, forming and weld related defects such
as Mismatch, Bead Height (either too high or too
low), weld Undercut, Freeze line (cold weld), profile
Deflection and many other types of defects can be
detected.
By placing the inspection system right after the
scarfing process, problems that may arise from
random height variations of the tube as it is feeding
into the scarf cutting tools or from broken/dull scarf
cutting tools that leave behind a less desired scarf cut
can be detected. Both sensor heads can be connected
into a single HMI enclosure that can display the data
from either the Post Weld or the Post-Scarf sensor
head.
