Carrying out and applying slurry blast coating and paint on offshore platforms of drilling rigs and tankers in service
By combining water with abrasives, this device produces up to 90% less dust and saves up to 80% in the consumption of grit or mesbar, in addition, having a certificate (ATEX) can be active in the conditions (No shot down required) Oil and gas rigs and refineries can be used without the risk of explosion.
Also, because the water becomes powder with the grout, the amount of water remaining is very small and easily dried by the air pressure of the device.
:Slurry blast
Benefits of Slurry Blast and modern device used
When the abrasive is mixed with water in the tank of the device, a slurry (wet abrasive) is formed which under air pressure (compressor) performs surface preparation operations more effectively than the sandblasting method.
Due to the various parameters of the modern slurry blasting machine, Wet Abrasive Blasting operation is much more controllable than other surface preparation methods and has various advantages.
1. The device has ATEX (Explosion Proof) standard and is suitable for working on oil and gas platforms while working or the deck of tankers.
2. Removal of dust from the workshop environment compared to sand blasting: which makes it suitable for working on oil and gas platforms and there is no need to remove F&G systems and other systems from the circuit.
3. Compared to other methods such as hydroblasts, it consumes very little water and in fact we only have a wet surface.
4. Surface preparation is done at a higher speed.
5. It has a higher surface quality and also has the same surface roughness as other surface preparation methods.
It is significantly less than the slurry operation, and this speeds up the whole job.
7. Enables the use of corrosion inhibitors (inhibitors) during work and allows staining to be done up to about 48 hours after wet blasting operation and does not require re-blasting.
8. According to NACE standard: WAD / 2 / SSPC, WET Blast method is used for low level of salt on the surface.
