Periodic maintenance of the lubrication-cooling emulsion lines of machine tools is often overlooked, until problems become impossible to ignore. The recirculation of this emulsion provokes an unavoidable sedimentation which progressively obstructs the passage of the fluid, due to layers of lubricant which solidifies on the walls of the pipe, reducing its cross-section. In this video we see a cleaning operation on a plant with only 6 years of life. It can be seen that on a 1/2" line, about 20m long, enough deposits have been removed to fill almost three 1liter bottles. Addressing this problem with preventive maintenance operations helps to keep the lubrication system always efficient, the optimal flow of which avoids premature wear of the tools; avoiding to wait for the total obstruction and the solidification of the material allows to solve the thing in an easy way, before it is too late, when by now the only solution would be to replace the pipes in their entirety.
With the help of the new R type projectile, the abrasive
removal capacity, such as for rust deposits, is further
enhanced. As you can see in the movie, the projectile is
easily used on a bent tube piece.
Used in combination with C type projectiles, it is possible to effectively remove the deposit on the inner wall of the tube.
This movie shows the cleaning of a liquid technique mortar
conveyor system. The 135 mm line is long a hundred meters.
After the shooting of the projectile, you should see the release of the product, still good for sale, remained inside the pipe. In the event of a traditional washing with water or other liquid product, the product would be wasted. In addition to the residual product, the projectile also removed the old mortar deposits left inside the pipeline during the earlier production cycles. The mortar was solidifying on the inner walls of the pipe.
Note the importance of being able to completely remove the residues of old product that, if left to mature inside the plant, may lead to the formation of bacteria.
In the movie you can see the procedure performed for
cleaning and degreasing the liquid oxygen line already present
in order to enable it for use. The pipe showed evident signs
of corrosion from rust whose removal required the firing of
several dry projectiles having different diameters to
gradually remove the coarser debris.
Following the removal of the rust deposits, we spread a degreasing agent over the entire inner wall, soaking other projectiles with the same product and making them passing a few times to remove the remaining excess liquid degreaser inside the tube. Finally a dry projectile was fired in order to clean and remove all traces of dust and liquid degreaser residues, so supplying a clean and dry pipe, ready to be used. This type of operation allowed the customer to save several thousand Euros and a considerable amount of working days that would have be needed for the replacement of the underground pipe, while in our case the cost was tens of times lower and the time required for cleaning was less than two hours.
Mixed floor plant/ radiators without plate heat exchanger for
isolating the low / high temperature circuit.
N° manifold ways = 8
Pipe diameter = 17 mm
Tube length per circuit = approx. 110 m
Year of start-up = 1999
Year of first cleaning = October 2006
Plant status before cleaning = reduction of the expected performance in 10/15%
Discharge water temperature before cleaning = 35°C
Discharge water temperature after cleaning = 32°C
Timing of intervention:
- Plant discharge = 60 minutes
- Cleaning with projectiles = 15 minutes
- Plant charge and start-up = 120 minutes
A demonstration of how you can clean an underground cooling
pipe of tool machines, almost completely blocked by old oil,
metal dust and other contamination. The tube consists of a main tube with a length of approx. 150
meters and an internal diameter of 42 mm, "T" connected with
several tubes having an internal diameter of 19 mm.
You may notice the speed and the ease with which you are cleaning a pipe composed of curves, ball valves and tubes of different materials (steel - rubber).
With this system, in a few hours and by using few projectiles, we cleaned the pipe, avoiding its replacement which would have required several days of work and production stop with high costs.
This movie shows the main steps referring to a cleaning operation of a pipeline to transport LPG from the outside to the inside of the shed. The plant has been cleaned by the company Bertini Divisione Impianti s.r.l., with the help of our tube cleaning solution used for the internal cleaning of pipes. The plant to be cleaned was at the premise of a leading Italian manufacturer of pipes. The pipe of 1" in diameter was cleaned very effectively as you can see from the row of projectiles used... The first projectile was obviously very dirty and could not be enough to completely remove the inevitable oily residues that are deposited on the inner walls during the regular gas flow. After several passages, however, you can see how the situation improves until it reaches a level of cleanliness on the inside so high that there were no residues on the bullets. This result could be obtained thanks to the use of industrial Simple Green Extreme degreasing compatible with any type of material, fluid or gaseous substance and totally biodegradable. A very important operation to be carried out at regular intervals to keep the entire system at peak efficiency.
