Corrosion resistant
tube and pipe
Bimetallic tubes for high pressures and
corrosive conditions
Be Ca Engineering Soc Coop is a
manufacturer specialising in bimetallic
tubes and hydrostatic and pneumatic
testing systems for straight or bent
tubes and pipes.
Heat exchangers are stressed devices,
for example when installed in power and
nuclear plants, in fertilisation and urea
treatment systems, or in chemical and
petrochemical industry, above all due to
the high working pressure, temperature
and corrosive atmosphere.
Strength and protection against
corrosion are the main technical
specifications for tubes used in heat
exchangers. For this purpose Be Ca
Engineering offers bimetallic tubes.
The patented technology creates a
unique bimetallic tube, starting from two
distinct tubes with different materials.
For example, if the corrosive atmosphere
is due to the fluid located inside the
tube, the outer tube could be a high-
stress-resistant alloy (stainless steel,
iron, titanium, duplex), whereas the
inner tube could be a high-corrosion-
resistant alloy (copper, aluminium-brass,
zirconium).
Bimetallic tubes offer a technical and
economical solution for the production
of heat exchangers with high stress and
corrosive conditions.

WHEN a US tube manufacturer
repeatedly experienced premature
corrosion on pipes, end-user warranty
claims and unanswered service requests
to their coatings supplier, management
realised it needed serious help from
industry experts. They took action and
contacted Quaker Chemical Corporation.
Quaker is a global provider of process
chemicals, services and technical
expertise to a wide range of industries.
It offers a complete “front-to-back”
product portfolio for the tube & pipe
industry, including lubricants, coolants,
cleaners, rust preventives and coatings
– including UV coatings.
Quaker used its integrated knowledge
of steel manufacturing, metalworking
fluid processes and coatings chemistry
to recommend an appropriate solution
that would not only increase the
flexibility of the tube coating, but also
offer superior corrosion protection and
increase the cosmetic appearance of
finished tubes. The resulting elimination
of rejects/returns and improved quality
not only decreased costs, but also
opened new sales opportunities for
the manufacturer. Quaker’s customised
QUAKERCOAT
®
product is a high-
gloss, 100% UV-curable, permanent
protective coating. This product offers
a lower total applied cost, because
the formulation chemistry provides
balanced properties for flexibility,
hardness and corrosion protection.
In addition, this eco-friendly line
contains zero-VOC emissions and has
virtually no overspray and very limited
discharge.
By
switching
to
Quaker’s
QUAKERCOAT
®
UV product, the tube
manufacturer was able to: eliminate
the premature corrosion issues,
which resulted in significant cost
savings ($85,000 saved in lost claims
and $25,000 saved in rework over
an 8-month period); receive regular
technical service visits from Quaker,
resulting in increased worker morale
because the operations staff felt taken
care of by their management team; and
increase its own market image and as a
result gain new business.
Quaker Chemical Corporation is a leading
global provider of process chemicals,
chemical specialities, services, and
technical expertise to a wide range of
industries – including steel, aluminium,
automotive, mining, aerospace, tube
and pipe, coatings and construction
materials. Quaker’s products, technical
solutions, and chemical management
services enhance customers’ processes,
improve product quality, and lower costs.
