Oil Flushing

GULFINCON INTERNATIONAL LLC have the equipment and experienced manpower to perform oil flushing services anywhere in the Middle East.
After new fabrication or repair of piping and tubing, it is important to flush the lines to remove all foreign debris (welding slag, dirt, metal fines, etc.), thereby preventing premature component failure.

Nitrogen Helium Leak Testing

Leak testing is a method of analyzing industrial storage and transport equipment (vessels, tubing, and pipelines) for defects. Nitrogen gas testing done before pipeline commissioning allows oil and gas operators to safely prepare their systems for first use.

This type of testing forms an integral part of safety protocols in different industrial settings.

GULFINCON INTERNATIONAL LLC has been actively providing this service across UAE and the Middle East.

System Drying by Vacuum, Nitrogen or Air

Hot Air

The pipeline is fed at one end with a supply of heated air from an air compressor. Heat energy is absorbed by the water in the pipeline which speeds evaporation. The water vapor is transported by the flowing air out of an exit port located at the opposite end of the pipe to the hot air entry.


In this method the pipeline is completely sealed and then a single port is connected to high power vacuum system, which extracts air from the pipeline. Over a period of time, the humidity level in the outlet will reduce rapidly as a stable vacuum level is formed.


Instead of using hot air, an inert purge gas such as nitrogen may be used. Two advantages of using nitrogen are that it will be very dry and therefore have a high capacity for water adsorption and also that it is inert and can be used to prepare pipelines or process vessels that will later contain explosive or flammable gases.

Nitrogen Enhanced Pre-Cooldown

Nitrogen is used to cool and inert pipeline system during the shutdown process for maintenance work. The inert environment created from nitrogen prevents any combustible reactions from occurring. Flowing cold nitrogen through a unit can also substantially reduce the amount of time it would take to cool the unit than if it were allowed to cool naturally.
