In the oil and gas industry, 'Christmas trees' are not a seasonal
decoration. They are critical components that make it possible
to control and monitor the wellhead and stop the oil flow in an
emergency.
To help manufacturers promote integrity and uniformity
in their quality control process, Cortec® recommends the use of
VpCI®-649 for corrosion protection during and after hydrotesting.
The corrosion risk
Hydrotesting Christmas trees is an important part of ensuring that
these complex assemblies of valves and gauges will withstand
pressure when placed on a wellhead. Since hydrotesting involves
water, it introduces the risk of corrosion, which is why a corrosion
inhibitor like VpCI-649 is imperative for a successful hydrotest.
Corrosion protection beyond hydrotesting
One of the great aspects of VpCI-649 is that it can provide
corrosion protection beyond hydrotesting. Dosed at a high enough
concentration, VpCI-649 can leave behind a corrosion inhibiting
film that will continue protecting Christmas tree internals after the
hydrotest. This is a great option for manufacturers that need to ship
their Christmas trees far away through harsh conditions, especially
those offshore.
Economy and uniformity for manufacturers
In addition to providing internal corrosion protection, VpCI-649 is
a great way to reduce waste and ensure uniformity. Multinational
manufacturers of oil and gas equipment can ensure uniformity
in their hydrotest specifications by adopting VpCI-649, which is
available for distribution in more than 100 countries. For greater
economy, VpCI-649 can be reused multiple times if the solution is
monitored for purity and topped off when the concentration drops.
