Reduce costs for purging
large-diameter pipes
Care is necessary when welding
large-diameter pipework in stainless,
duplex and chrome steels, nickel alloys
and zirconium. When welding
such reactive materials, they need to
be purged of oxygen before, during
and after welding, which can cause
a huge expense when they are of a
large diameter. QuickPurge Systems
(photo), which are manufactured in
sizes up to 88 in. (2,235 mm), dramatically
reduce the space that needs
to be purged, thereby reducing purging
time dramatically, resulting in savings
in both time and gas costs, says
the company. QuickPurge is simply
inserted into a tube or pipe, inflated
within the pipe, restricting the area
that is to be welded, reducing the O2
level down to 100 parts per million
(ppm) within minutes. QuickPurge
has an additional gas input line, which
means that extra purge gas can be
introduced for applications such as
this, thereby achieving a much faster
purge, down to the lowest oxygen
levels, which is perfect for larger-diameter
pipes where quality welds are
required. - Huntingdon Fusion Techniques

Manage flanges with
these tags
Leaks caused by improperly sealed
flanges connecting pipes, valves,
pumps and other equipment to form
piping systems may cause corrosive
damage. Such damage is both expensive
and time-consuming to repair,
and puts both workers and others
at risk of exposure to dangerous
pipe contents. Using this new family
of tough multi-colored flange-management
tags gives inspectors and
field workers peace of mind knowing
that the work has been done accurately,
on time and by professionals
in the field. The tags are made
from polypropylene, so they are
durable, and resistant to water, tearing
and ultraviolet (UV) light. Highly
visible " at-a-glance " status signifies
each stage of inspection - flange
assembled, flange tightened, flange
broken and inspected. Each stage
is perforated and can be torn off to
show completion. An 8-mm hole at
the head of the tag enables the tag
to be easily attached to the flange
using cable ties. All tags can be customized
to include company logo
and sequential numbering for traceability
with orders above 500 units.

Recycling silicone tubing
waste into silicone oil
This plastic- and silicone-tubing
manufacturer is now able to recycle
the waste from its silicone tubing and
braid-reinforced hose extrusion processes
(photo). The recycled scrap
finds new life as silicone oil for industrial
applications. Tubing scrap is
created at the beginning and end of
the extrusion process as technicians
adjust the equipment for proper tubing
dimensions. That tubing, and
any other that does not meet the
company's strict quality standards,
is collected and stored in bulk containers.
The containers
are
then
shipped to ECO USA, a company
that specializes in reclaiming silicone
oil. At ECO USA's silicone recycling
plant in Parkersburg, West Virginia,
silicone is ground into small pieces,
mixed with catalysts and heated
to break down its chemical bonds.
Liquids from this stage are filtered,
refined and polymerized into silicone
oils and filtered again. The final
product is silicone oil that is comparable
to virgin silicone oil manufactured
from silicon dioxide. The oil is
used in industrial applications, such
as lubricants, sealants and automotive
dressing. - NewAge Industries,
