Elcometer 1001 Corrosion Under Insulation Gauge - Discontinued

Discontinued Product – for servicing use only

Pipeline failure through corrosion under insulation causes supply shortfalls, economic loss and environmental pollution. Early detection of the presence of moisture significantly reduces the risk of corrosion developing underneath pipeline insulation.

The Elcometer 1001 detects and identifies the location of any fluid leak on thermally insulated pipes, 24 hours a day, 365 days a year, preventing corrosion and reducing unplanned repair and maintenance costs.

 

CUI 

Pipeline failure through corrosion under insulation causes supply shortfalls, economic loss and environmental pollution.

User Friendly
  • Ideal for use in the oil, gas, chemical, water and power generation industries, on or off-shore

  • Straightforward replacement - a new module can be screwed on to the original funnel assembly
  • Maintenance free for 5 years with simple testing on site at any time

Accurate

  • Identifies approximate location of fluid leak, preventing unnecessary removal of good insulation
  • Detachable sample vial can be sent for further testing or chemical analysis of contents

Reliable

Efficient

  • Fast installation by one operator with minimal tools required
  • Battery life of 5 years
  • Each module has unique serial number for traceability

Powerful

  • Extends the life of pipe insulation
  • Can reduce pipe replacement due to Corrosion under Insulation
  • Fail safe high visibility fluorescent float as a visual indicator
  • Powerful high intensity flashing LED alarm guaranteed to flash for a minimum of 7 days after actuation
   

Fluid, by its very nature, will flow to its lowest point and collect where it is able. The Elcometer 1001* simply allows the fluid to collect in the detection and indication device raising the fluorescent float and activating the high intensity LED, immediately alerting operatives to the potential for Corrosion Under Insulation, and to the Health and Safety issues surrounding leaking pipes.

Moisture ingress will travel (wicking effect) through the insulation, and enter the collection funnel of the Elcometer 1001.

With the potential to reduce inspection, repair and maintenance costs, each self-contained Elcometer 1001 device will constantly and independently monitor, indicate and alert for the presence of fluids, remaining active for 24 hours a day, 365 days per year for up to five years (LED Battery).

CUI

Fitted to the underside of pipelines the Elcometer 1001 collects fluid as it flows to the lowest point.

 CUI

When fluid is detected a high intensity LED and highly visible fluorescent float provide a visual indication of the presence of liquid.

 

Detecting Leaks

Some process products and pure ‘hydrocarbon’ will not activate the high intensity LED, however they will raise the highly visible fluorescent float, pinpointing where the product release under the insulation has occurred. The collection vial of the Elcometer 1001's device can be unscrewed and the contents taken away for detailed analysis. A replacement vial can be attached to the Elcometer 1001 whilst the escaped fluid is examined and remedial actions reviewed.

Location and Frequency of Corrosion Under Insulation Gauge

To ensure the Elcometer 1001 Corrosion Under Insulation Gauges can effectively detect leaks under insulation, it is recommended that on site assessment be carried out by suitably qualified risk-based inspection (RBI) Engineers.

 

Low Risk Applications

For low risk applications where there is minimal threat to business interruption, human health or environmental damage from a leak caused by corrosion, the minimum requirement is to install devices every 5-10 metres and wherever any of the following are installed:

  • Elbow
  • T joint
  • Horizontal pipe work low point
  • Bottom of vertical pipe work
  • Other insulated extrusions on pipe work
  • Vessels
  • Drain-holes
  • Drain-plugs
  • Drain-tubes
Medium Risk Applications

For medium risk applications where there is environmental risk and possible business interruption, it is recommended that the Elcometer 1001 is positioned every 2-5 metres and every junction/low point.

 

High Risk Applications

For high risk applications posing a threat to human health it is recommended that the Elcometer 1001 is positioned every 1 metre along all pipe work as well as all junctions/low points.

 

By installing an Elcometer 1001 at regular intervals, as one device is activated and another adjacent unit is empty, the point of the leakage can be determined. Should an adjacent device also become activated, the direction of the flow can be determined.

In Use

Regular checks: Each Elcometer 1001 CUI device should be checked at regular intervals to see if either the LED is flashing or the float is visible. In either case, the cause is either moisture or fluid under the insulation.

 

Once triggered the unit will flash for 7 days before the battery is exhausted. In the case of an alarm condition the source of the leak should be ascertained and corrective action taken.

On re-instating the insulation, the Elcometer 1001 MUST be replaced.

 

Service Life: The Elcometer 1001 has a service life of 5 years after which it must be replaced, if the installation is sound, a new module can be screwed into the original funnel assembly.

   

Installing Corrosion Under Insulation Gauge

The Elcometer 1001 is designed to function correctly when fitted at the 6-o’clock position at every joint of the thermal insulation on an insulated pipe, on the bottom of bends and on vessels and tanks - only where visible for inspection.

   

New Installations

1. Installing the Elcometer 1001 can be achieved by fitting each unit tight up to the last section of the thermal insulation prior to fitting the next section.

 

Thread a fixing strap through the flexible fixing strap and loosely fix it around the pipe.

 

Slide the funnel assembly up to the edge of the insulation. The funnel must hang vertically with the threaded end facing down.

 

2. Cut the thermal insulation away around the funnel to ensure a snug fit. Tighten the fixing strap and slide up the next piece of insulation.

3. Adjust the height to ensure the threaded section of the ‘o’ ring seal is below and clear of the outer cladding.

 

4. Make sure that the point at which the funnel exits the outer cladding is fully sealed with silicon adhesive sealant after all protective layers and treatments have been applied to the thermal insulation.

 

5. Holding the collection funnel in place using a spanner, each funnel has a spanner ‘Seating’ to assist the ‘Tightening’ process, ensure the ‘O’ ring seal is engaged when screwing the housing to the exposed collection funnel screw thread.

1. Using a standard drill with a 30mm diameter drill bit, drill the outer cladding on the underside of the insulation at the 6 o’clock position and core the insulation media to expose the pipe surface, taking care not to damage the pipe surface.

 

Leaving the protection cap in place, take the black collection funnel and adjustable shaft and extend the shaft to its maximum height.

 

2. Insert the collection funnel until resistance is felt.  The shaft has now touched the pipe surface. Continue to push the collection funnel until the funnel moves no further (this adjusts the funnel to the correct height to the thickness of the insulation).

3. Using a standard (in-use) sealant or mastic, apply to the joint of the funnel onto the outer cladding, ensuring there are no gaps or holes, smooth over and allow to cure.

 

4. When the sealant/mastic has set, apply a strip of quality metal sealant tape for added waterproofing and additional support.

 

5. Remove the protective cap. Gently screw on the housing by hand, holding the collection funnel in place using a spanner, ensure the ‘O’ ring seal is engaged when screwing the housing to the exposed collection funnel screw thread.
