Serimax – Powering Progress in KSA on water pipeline infrastructure

Serimax is proud to highlight a key milestone achieved on the Ras Al Khair Desalinated Water Pipeline Project, where we have been actively engaged since 2025 across both project Sections, working with two different contractors.

With more than 42,000 welds of 88” pipe planned, this project represents one of the largest and most technically demanding pipeline welding scopes in the region. Serimax is pleased to announce that we have now surpassed 50% overall progress, reflecting the strong coordination, expertise, and commitment of our field teams. Leveraging a threestation Saturnax configuration welding directly in the trench, Serimax has achieved a best production performance of 42 joints in just 10 hours on Section B1, demonstrating our capability to deliver high productivity even under complex site conditions. Quality remains paramount to our operations. On Section B1, which comprises 22,700 welds, our cumulative repair rate stands at an outstanding 1.75%, based on 100% weld inspection.

Such a low rate is exceptional for 88” pipe, considering the wall thickness and the ovality challenges typical of this type of pipeline. This performance illustrates Serimax’s deep technical experience and decades of fieldproven knowhow gained through the successful execution of +4 million welds since 2009 in the Middle East. This milestone reinforces Serimax commitment to elivering safe, reliable, and highquality welding solutions as the project moves toward successful completion.
