Test: Pexgol vs HDPE for Brine Transportation

Establish the best behavior of Pexgol pipes to the formation of scale that produce the transport of brine. This will be done by obtaining less scale deposited on the internal surface of the Pexgol pipe compared to an HDPE pipeline operating both under the same conditions.

The above will be determined by evaluating the results of the following
measurement variables:

• Thickness of the deposited incrustation, this will be measured with a flexometer. The unit of measurement will be in millimeters.
• Amount of washing cycles required during the test period, the number of times it was necessary to wash the HDPE line and the Pexgol line during the 30 days of the test will be established.

First 7 days of trial:

Note: At the request of the YLB supervisors after 7 days, the pipes were repositioned.

Results after 14 days of testing:

Pexgol Pipe:

HDPE Pipe:

Discharge to the pools: Pexgol vs HDPE

Suction from the pumps: Pexgol vs HDPE

Discharge elbows: Pexgol vs HDPE

Discharge to the pools: Pexgol vs HDPE

Discharge after 7 days: Pexgol vs HDPE
