Caustic (NaOH) injection keeps recycled-water pH on target, but it also bakes rock-hard scale onto everything downstream. At one oil-sands facility, that meant their knife-gate and butterfly valves were seizing every 6–12 months, throttling production and burning through maintenance hours for almost 14 years! 😬
Summit’s fix: install Wey Valve Inc’s scale-cutter knife gates, which worked like a charm. Multiple 24-inch units were installed on pump suction, discharge, and bypass lines, effectively shearing through heavy scale while maintaining reliable isolation and smooth operation.
Inspections revealed that the valves were in excellent condition two years after installation. Only the soft goods were replaced, and the valves were reinstalled. After more than five years of operation, these valves continue to perform flawlessly. 💪
When it absolutely has to work, choose Wey!
