High performances in harsh weathering conditions
Project Highlights:Transportation of brackish water from the Dead Sea to main pumping station
Customer:Dead Sea Works
Location:Rahaf dry riverbed, Dead Sea
Working conditions:Over 20 years of direct sunlight (UV) exposure, ambient temperature variation from 47oC to -5oC, rock build up from seasonal floods
Pipes used:PEXGOL Ø355 CLASS 10 (SDR 16.2)
Application:Brackish water transportation
Length:A 120 meter pipe section across a100 meters wide riverbed
Year of installation:1993
The Dead Sea works had to lay a water line across the Rahaf dry riverbed, 100 meters across in order to transport water to the main pumping station supplying water from the Dead Sea to the plant. Powerful seasonal floods flow into the riverbed several times a year, causing heavy rocks and soil to drift and swipe everything in the way. The original asbestos pipe was laid in a trench crossing the riverbed but the floods uncovered the pipe and damaged it, which required replacement of the pipe.
Based on two decades (at the time) of exposure to harsh conditions, it was clear PEXGOL was the best solution for the client. A PEXGOL Ø355 CLASS 10 (SDR 16.2) pipe was laid in a ditch across the riverbed, without sand embedding. Despite being uncovered multiple times by the floods since the installation in 1993 the pipe has been working with no failure.
The initial pipe was made from combined short sections that required a complex installation and reinforced foundations. The Mean Time Between Failures (MTBF) was several years. The PEXGOL pipe was easily installed and covered with natural fill and was laid directly in a ditch. It is working with no failure since 1993.
