Simple yet Obvious…
Detect, test and identify any traces of fluid
on the pipe surface, under the insulation,
or within the insulation media itself.

Conclusions:
“H2Obvious detectors will detect the presence of fluid in a situation
of fluctuating temperatures and cyclic vaporizing and condensing
within the insulation”
“H2Obvious is able to detect fluid in the insulation which has not
(Yet) reached the pipe surface”

Recommended Fitting
Vertical pipe:
1 device fitted at bottom end.
Horizontal pipe:
1 device fitted at each and every
insulation joint.
(Typically 1 metre intervals)

Where to Install? Any new on/offshore installations
As part of fabric maintenance
As part of routine strip and search
Any insulation types (Excluding “Glued” Media)
Any pipe material maximum Temp. +275 Deg. Celsius
Any pipe diameter
Where (currently) the underside of pipe and insulation are visible

Interval Inspection/Testing
Any device at any interval may be unscrewed, a
small amount of water poured in to the unit, await
the LED to commence flashing and the float to
raise.
This unit may be dried (Thoroughly) and refitted.
This interval testing does not disturb the insulation
NON - Intrusive Testing

Replacement when Activated
When one or more units are activated, there is fluid
either on the pipe surface under the insulation or within
the insulation media prior to it reaching the pipe
surface.
(Fluid in the unit may be taken away for sampling/testing for either water
hydrocarbons other fluid product)
The insulation in these locations (Only) will be
stripped, remedial works carried out with new complete
devices fitted with the new insulation.

Fluid Sample From Activation
1. Should the sample be water, the PH can be ascertained to
determine whether corrosion under insulation is of a higher or
lower risk at this time.
2. If the sample is hydrocarbon or other fluid product you have
an escape and the source of the leak is easily identifiable.

Replacement if Inactive
In year 6 the encapsulated units (only) will be
unscrewed, discarded/recycled and replaced without
disturbing the insulation.
Giving a further 5 years assurance of fluid monitoring
& hydrocarbon (product) leak detection.
