Corrosion Under Insulation

“industry headaches”



a different approach

A simple and effective all in one

solution for detecting fluids….



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.

NON-Intrusive Replacement
