Projectiles Shooting - Rental Solutions
Shooting through special projectiles at low pressure is increasingly being chosen by end customers and/or contractors. This method is very interesting when large tube bundles have to be cleaned quickly, effectively and safely. Think of large type heat exchangers / coolers with 1000+ tubes.
Biggest advantages of these methods
This cleaning method is increasingly chosen because it offers enormous advantages over ''traditional cleaning methods''. The main arguments for this are:
- Speed. Projectile cleaning offers an extremely quick cleaning time, therefore time savings are enormous. You can shoot through tubes of various lengths within seconds. With 2 people, you can clean about 1000 tubes per hour under the right conditions. That's faster than any method currently available!
- Cost reduction. Projectiles are relatively cheap and can be reused multiple times, depending on the type chosen. Therefore, the cost per cleaning is much less than, for example, with high pressure.
- Safety. Projectiles are shot through at low pressure. This is not only safer for the operators, but also for the system/tubes itself. This is because tubes are not exposed to high pressures internally, as happens in high pressure cleanings of +200 bar or more.
- Water consumption. Projectiles shoot through the tube within seconds. So there is almost no water consumed to clean a tube. Maybe a few liters per tube max.
Deployment Cleaning Technology
Projectile cleaning is used in almost every type of industry. Over the years, more and more industries have included this in their (un)planned cleaning activities. Examples include:
- Power plants (Nuclear and non-nuclear)
- Petrochemistry (Oil & Gas)
- Maritime (On board of large ships, including dredging)
- Waste Processing Plants
Two different methods available
GWB Rental Solutions offers both methods for rental. In principle, both devices do the same job; shooting special projectiles through the tubes of a bundle. Yet there is a big difference between the 2 methods, more information below:
- Method 1 = Pneumatic (QS-300)
This QS-300 ''Quickshot'' is a compact device that works on the basis of 90% compressed air and 10% water. Compressed air is thus the propulsion in this method. The water serves as an additional cleaning agent to flush the loosened deposits out of the tube. This method is very interesting, when heat exchanger tubes have light contamination such as algae, sludge and mud. Harder contamination is also possible, but up to a certain limit.
Quickshots are easily carried in a case on location and are operational within minutes. This is the biggest advantage of this method. In addition, no electricity is required as the QS-300 only uses water and compressed air.
- Method 2 = Hydrostatic (BFP System)
The BFP system is a larger device and specifically designed to clean almost all types of deposits (with the exception of extremely hard fouling). This system is based entirely on kinetic-hydrostatic technology. This means that the system works entirely on water pressure. With 130 liters per minute (practical consumption is much lower) and +- 30 BAR, you can shoot through all types of projectiles.
The main advantage of this method is that the cleaning effect is a lot better than the QS-300, purely because much more water is used. This leads to a better flushing effect in the tubes, which often results in a maximum cleaning effect. The system is larger and uses 380V power, this is something you should take into account. In addition, this system needs sufficient water supply to perform well. A good preparation is therefore very important.
