AL YASAT 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.
System Drying by Vacuum, Nitrogen or 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.
