The largest National Oil Company in the Emirates of Dubai, which has large storage facilities storing oil, petroleum and petroleum products, and these are transported and used by end-users, and one of the users is local international airport.

In one of the storage tanks facility the fire water line leaked because the coating system failed. The pipeline came in operation just 3 years before and in high tide, sea water on daily basis submerges the pipeline which becomes a very demanding situation for the coating system. The PE backed coating system failed and resulted in leaks and holes in the pipeline, within a span of 3 years.

The fire-water pipeline being a highly critical pipeline for fire safety, had to be shut, resulting in halting of supply of fuel to local international airport – which could seriously affect the operations of one of most busiest airports in the world.

2. Media: Fire Water
3. Environment: Sea water submerged
4. Original Coating: Polyken PE Tape

After reviewing all the options of field applied coating systems available, customer opted for RD-6 because of superior material composition of RD-6 which provides complete protection from water ingress. RD-6 also provides strong resistance against soil stresses, especially where water table keeps changing on daily basis. Client has been using RD-6 since 2015-16.

RD-6 is made from Polypropylene (PP) backing in mesh-back design, being highly rugged coating system opposed to other competitors which use Polyethylene (PE) backed coating systems, which easily fail in aggressive soil conditions. RD-6 has won the confidence of client as a coating of choice.

One of the largest National Oil Companies in the Middle East, the company operates vast storage facilities for oil, petroleum, and refined products, which are supplied to a wide range of end-users, including a major international airport.

A 68 mm Diameter Storge Tank Roff with 65 locations of severe external & pitting corrosion leading to numerous through wall defects. The aim of composite repair system is to restore the tank roof upper skin plates using a patch repair process. The defect sizes were varying through wall penetrations of 10–250 mm diameter extending up to 3,000mm in length in varying locations.

• Applications during summer months with high ambient air temperatures
• Bespoke adhesive required to cope with thermal movement of the tank
• Due to spark risks, the surface preparation is limited to ST-3.

1. Tank Diameters: 68 mm
2. Media: Hydrocarbons (Highly Flammable)
3. Environment: Near

After reviewing all available repair solutions, the client opted for a composite repair system due to its superior material properties and proven performance in restoring structural integrity. The composite system effectively reinforces areas affected by severe external and pitting corrosion, providing long-term protection against hydrocarbon exposure and environmental degradation.

One of major Oil Refinery, based in Karachi, Pakistan with a network of cross-country pipelines, which passes through highly corrosive and demanding soil conditions.

The refinery has an extensive pipeline network passing through the city of Karachi, Pakistan from the refinery to oil jetty, through urban residential areas, open sewer canals, industrial areas. These pipelines carry the lifeline of the refinery, all hydrocarbons, and pose a big challenge to safely maintain these pipeline assets, as any damage or leaks could pose environmental, safety and daily-life disruption risks. The refinery has extensive experience in using different coating systems but to their experience many types of coating systems failed because of the highly demanding and corrosive soil conditions through the pipeline routes.

The refinery’s pipelines pass through open sewer canals. These open sewer canals carry waste which has a combination of wastewater and debris. The sewer wastewater being acidic, on one hand poses a challenge for the coating system and on the other hand debris can potentially damage, by impacts, the coating system. This situation where pipeline being in a submerged, acidic wastewater environment and abrasive impacts of debris is beyond the capabilities of many field applied coating systems.

2. Media: Hydrocarbons
3. Environment: Open Sewer Canals waste

After reviewing the physical properties of RD-6 and testing in aggressive soil environments, client has been using RD-6 since 2015-16. RD-6 uses Polypropylene (PP) backing in mesh-back design, being highly rugged coating system opposed to other competitors which use Polyethylene (PE) backed coating systems, which easily fail in aggressive soil conditions. RD-6 has won the confidence of client as a coating of choice.
