•Q - Why VCI
technology for boilers and
related components?
•A - Vapor Corrosion Inhibitors (VCI) function by releasing or
vaporizing into the air space
and laying out on all the metal surface a protective film. This technology is ideally suited for dry lay-up (although wet lay-up is
possible) and can protect for up to
two years! Anytime a boiler or related
equipment is non-operable and can be drained,
VCI technology is an excellent
choice.
•Q - Can I inspect the boiler with this material
inside?
•A - The vapors are not hazardous. However, it is suggested that appropriate
vessel entry safety procedures be
followed. Protective clothing should be
worn to avoid/minimize skin contact
with any residual product in the boiler.
•Q - Can I start-up the boiler with this material
inside?
•A - Yes, the products
are water soluble. Ideally, a fill & flush would be
performed prior to
start-up but is not absolutely necessary.
Boilers with a history of foaming and carryover problems should fill & flush first.
•Q - How do I determine dosage?
•A - Dosage is determined strictly based on system volume
unless otherwise noted.
•Q - How do I assess performance?
•A - Corrosion coupons have been used or you can simply
visually inspect the boiler routinely. A retractable corrosion coupon holder can be
rigged if vessel opening is not
desired or practical.
