Thin film innovation assists with
complicated system assembly
EUROTUBI Pressfitting is a system of
tubes and fittings in stainless and carbon
steel, used for hydrothermosanitary
installations and assembled with
press-technology.
In order to make installation quick and
efficient, the system’s manufacturer,
Eurotubi Europa, has added a thin,
coloured plastic film to the external
side of the o-ring seat. When the fitting
is being pressed, the plastic film tears,
falling off the fitting or remaining easily
removable by hand.
The installer will quickly notice if any of
the coloured film remains on the fittings,
making it unnecessary to closely inspect
each connection.
The new solution does not interfere
with the assembly of the system, and
permits the rapid verification of missing
pressings of the fittings, and so avoids
any possible leakage.

800ES gas non-return valves from Witt,
the gas safety, control, mixing and
analysis equipment supplier, have been
tested by BAM Federal
Institute for Materials
Research and Testing
in Germany for burn-out
safety up to 240 bar
(3,481 psi) with oxygen.
The 800ES non-
return valve, which
can also be used with
other technical gases
including hydrogen, is
designed for installation
in a gas supply system,
automatically preventing
creeping or sudden
reverse gas flow.
Burn-out safety measured at up
to 240 bar on non-return valve
Applications include cutting and burning
equipment, pressure control stations
and flammable gas supply pipelines.
The easy-to-install non-return valve is
less than 70mm long with a diameter of
18mm, and has a ¼" NPT thread. The
valve is manufactured in stainless steel,
which is more resistant to wear than
brass, and the valve seat and O-ring
used is dependent on the type of gas.
Carl Long, general manager at Witt UK
commented, “The one time test by BAM
helps users of this non-return valve
to obtain a permit for their gas supply
system. Not only does it enhance the
user’s safety by reducing the risk of
accidents, it makes savings on costs.”

Rubber-steel
flange gaskets
RUBBER-STEEL flange gaskets and
adjustable wedge rings have been proven
in use over many years in all areas of
pipeline construction. Kroll & Ziller has
40 years of experience in solving sealing
problems, and manufactures a range
of flange gaskets designed to provide
high efficiency, reduced operating costs
and reduced fugitive emissions. The
company’s sealing products are used by
steel mills, power plants, petrochemical,
pharmaceutical industries, and gas and
water companies.
Production disruptions and rejections,
maintenance and repair costs must
be prevented by choosing the right
construction materials. The risk of
possible environmental pollution must
also be eliminated. The policy of Kroll
& Ziller over the last 15 years has
been specialisation, research and
development in close collaboration with
large number of customers.
The wide range of standard gaskets
available for sealing flanges allows top
quality standardisation. The ease of
installation is attributed to the rigid steel
core, even with large nominal widths
and undesirable stresses.
