Comparative test for the transport of brine with HDPE and Pexgol pipes.

The Challenge

Albemarle salar decided to conduct a comparative test on their brine pipelines. The objective was to test the high resistance to scale formation that Pexgol pipes possess compared to conventional high-density polyethylene (HDPE) pipes.

Pexgol Solution

A Pexgol pipe was uncoiled by the main road from the salar to the parapet of 13D well, finally placing the pipe in the direction of 14D well to start the assembly according to its final disposition.

The flexibility of the Pexgol pipe allowed to fit easily into the layout, and its ability to be dragged greatly favored installation time.
Thanks to its high mechanical and impact resistance, Pexgol does not require the use of a special jacket.

For connection to the pump, a flanged coupling was used: clamp-type mechanical accessory with flange adjustment.

Working Conditions:

Flow: 120 m3/h

Pexgol Pipes

Pexgol 200 mm (8”), class 10


Brine transport


112 m / 367.45 ft

Sedimentation comparison: HDPE pipe after 30 days of use.
Sedimentation comparison: Pexgol pipe after 60 days of use.
After 30 days of operation, the HDPE pipe has incrustations with an approximate thickness of 50 mm.
HDPE pipes
Cleaning HDPE pipes presents a great physical wear and tear for operators, as they must hit hard to loosen the scale, which means more hours spent on maintenance.
