Chart Ferox vacuum-insulated pipe combines a proven experience
and the expertise of the two leading worldwide suppliers of
cryogenic and vacuum-insulated systems - CVI and MVE. The
Chart Ferox approach to vacuum-insulated pipe-systems (VIP)
serves customers in many significant ways.
Chart Ferox VIP use laminar radiation shielding within factory
sealed vacuum annulus to produce a lower inherent heat leak
than any other known method of insulation. This optimum efficiency
minimizes vaporization of cryogens and provides a controllable
high quality liquid when and where you need it.
Stainless steel construction and manufacturing excellence
eliminate preventive maintenance and emergency shutdowns associated
with more traditional insulated pipe systems.
Each Chart
Ferox VIP system is fabricated, evacuated, tested, and shipped
in prefabricated sections, or spools. Design flexibility is
provided by combining rigid and flexible sections, which are
joined by the unique Chart Ferox bayonet assemblies. Two types
of bayonets are available, either a positive seal type utilizing
the differential temperature contraction rates of Invar 36
and stainle ss
steel, or a close tolerance, "Johnson" style bayonet.
Both bayonet designs have long records of faultless operation
and eliminate the need for costly field joints, leak checking
and insulation. Bayonet joints allow for easy future expansion
and re-configuration of vacuum-insulated pipe systems.
Each Chart
Ferox vacuum-insulated system is custom engineered to include
design consideration specific to the particular application.
Chart Ferox also has a full "turn-key" capability
of vacuum-insulated systems, including design analysis, economic
evaluation, supports and accessories (valves, "keep full"
devices, etc.) supply, installation and commissioning. |
