Selection of Projectiles
The projectile cleans by being pressed against the internal surface of the hose, tube or pipe. This pressure is achieved as the projectile is approximately 20% larger than the internal diameter of the hose, tube or pipe. For instance, a 50mm projectile is recommended for a 38mm hose.
There are four types of projectiles currently available:
| TYPE |
DESCRIPTION |
| STANDARD |
For hose, tube and pipe without fittings. |
| COUPLING |
For assemblies and fine particles of contamination. |
| ABRASIVE |
For hose, tube and pipe where there is a build-up of contamination, surface rust or mill scale. |
| GRINDING |
For tube and pipe where there is a greater build-up of contamination, surface rust or mill scale. Tube and pipe must be straight for this projectile. |

Applicable to the Food & Beverage Processing Industry, and be used to separate the different pre-and post products incessantly produces in the same product line. It could be used as Coupling Projectiles once removing the small size contaminations. |
The table opposite out the recommended projectile sizes (standard, coupling and abrasive) for the particular hose, tube, pipe or assembly fitting. The table on page 8 sets out recommended sizes for grinding projectiles. Individual circumstances will vary requiring a smaller or larger projectile. If the projectile is too large it will not leave the nozzle and if its is too small it will not clean effectively.
The enormous variety in the types of couplings available today could also mean in some circumstances that the recommended size is inappropriate. When cleaning assembles, a reduction in projectile size may be appropriate, as all the recommendations are based on the most commonly used coupling sizes.
If the projectile remains lodged in the hose, tube, pipe or assembly then the CE Unit should be operated from the other end without a projectile. In this way the projectile will be ejected from the original entry. It is important to achieve an air tight seal. In the vent a nozzle does not fit snugly, try reducing the nozzle size.
Compri Technic’s Research & Development department can produce projectiles to suit specific applications. |
