Shot blasting inside large diameter pipes
The corporate philosophy of Cogeim
Europe is characterised by continuous
research and development of innovative
solutions in the field of shot blasting
equipment.
As a result of demands from clients,
the company’s team of engineers is
engaged in designing a specific shot
blasting plant, named GRT-I series, for
cleaning and descaling the inside of
large diameter steel pipes.
Plants of the GRT (engineered for
treatment and descaling the outside
of tubes) and the GRT-I series (for the
inside of pipes) are characterised by
precision, fine recovery and recycling of
grit, to ensure high productivity.
Their construction allows easy
inspection for the periodic replacement
of parts subjected to wear.
Cogeim Europe’s range of products
covers all requirements of blasting
works, such as springs treatments, die
casting, fasteners and steel structures.

New purge products
Sumner Manufacturing has introduced
two new purging products: Nylon
Expansion Plugs and the Purge Buddy.
Both products are suitable for purging
oxygen from weld chambers, and can
also be used to seal pipe as pipe plugs
or drain stoppers.
Nylon Expansion Plugs are available in a
range of sizes from 17 to 100mm (¾" to
4"). A 150mm (6") Aluminum Expansion
Plug is also available. The plugs can be
ordered individually, in sets of two, or
as a kit complete with storage case (the
kit does not include the 6" Aluminum
Expansion Plug). Each Expansion Plug
has a hollow shaft making them suitable
for purging.
The Purge Buddy is similar to inflatable
purge dam products, but has a single
inflatable bladder instead of two
inflatable bladders connected by a
stainless steel hose. It is available in
18 sizes from 50 to 900mm (2" to 36").
Each Purge Buddy is constructed of
a heavy-duty cotton/polyester material
impregnated with canvas that is heat
resistant to 100°C (210°F).
Purge Buddies inflate easily with a
standard bicycle pump, and include a
1.5m (4.8 ft) inflation hose and pull loops
for pulling through long lengths of pipe.
Purging products can be used to quickly
and efficiently create a reduced oxygen
weld chamber where it is critical to avoid
oxidation in the weld, such as when
welding exotic metals like stainless,
Duplex or titanium.
Sumner Manufacturing has served the
welding and mechanical contracting
industry for nearly a half century,
creating material lifts, jack stands,
pipe fit-up clamps, welding tools, and
material carts that are used in more
than 50 countries around the world in
numerous industries.
