Characteristics
At the time of the study, Marine Farms were fattening Pacific Salmon or Coho with a 7 month fattening cycle.
About the cultivation center:
- One modified vessel with a feeding system built in.
- Two main pipelines.
- Selectors outside the vessel in a floating platform.
- Set of feeder lines to the farming cages. The farming center has 15 cages but during the study only six cages, three for each feed
line, were in operation.
Variables to be Measured
- Wear.
- Quantity of fine and broken generated.
Measuring Points
The measurement was made at the major inflection points, where by historical background and by the turbulence that occurs in these areas, the pipes are more affected by the abrasion of the food.

Results
The average rates of wear give an expected result for Pexgol piping compared with HDPE piping under the same operating conditions. Average values of 3.26 – 4.69 mm / month for HDPE versus 0.0 – 0.26 mm / month for Pexgol were obtained. It is concluded that the operational life of the HDPE is projected at only 2.6 – 3 months under the feed rates assessed as average. Under the same conditions the Pexgol is projected to last nearly 18 times as long, that is 4.5 years (54 months).
Comparative table of wear measurement results:
| Measuring points (mm) | HDPE | Pexgol |
|---|---|---|
| P1 | 4.69 | 0.26 |
| P2 | 3.73 | 0.02 |
| P3 | 3.26 | 0.00 |
| P4 | 3.63 | 0.14 |
Economic Benefits
To analyze the economic benefit offered by the Pexgol pipeline for the salmon farming centers, considering only its longer lifespan due to greater resistance to wear, the total meters of feeding pipes of the cultivation center, its cost per meter and the replacement cost.
| HDPE | Pexgol | |
|---|---|---|
| Meters | 1.440 | 1.440 |
| Value USD/ m | 4.2 | 10.4 |
| Total Pipe Cost | $6,048 | $14,976 |
| Replenishment cost 1st cycle | $6,048 | – |
| Replenishment cost 2nd cycle | $6,048 | – |
| Total Cost | $18,144 | $14,976 |
To analyze the economic benefit offered by the Pexgol pipe due to the lower loss of fines and brokens, due to the fact that the Pexgol pipe has a roughness coefficient much lower than that of a conventional PE pipe, samples were taken from the Cellar, Dispenser and the output of the Selector.
This test was carried out in conjunction with the laboratory owned by the food supplier in Puerto Montt, through sieves required and recommended by the laboratory technicians. The measurements resulted in an economic saving of 63% only for this concept.
