Refinery engineers are always on the lookout for innovative solutions that can save money and improve the efficiency of the plant. Alcoa’s alumina refinery in Pinjarra Western Australia has found just such a product. Managing abrasive erosion in slurry pipes throughout the refinery is a constant battle. Alcoa is now using the new Timcast Forever Pipe from Veem Ltd.
The Timcast Forever Pipe is a bi-metal centrifugally cast pipe which consists of different inner and outer alloys. The inside layer is a high wear resistant Chrome white iron, while the outer layer is a carbon steel. The magic is created by casting the alloys together so they are metallurgically bonded. The final product has the best of both worlds. An inner layer that can handle the abrasive slurry and an outside layer that can handle the pressure and be welded and cut.
The Forever Pipe Development Manager Filko Bavcevich said “It’s a great feeling to deliver a product that has such a positive impact on the customer. The inspection of the Forever Pipe after 1 year in service found negligible wear. I was told the management want to see nothing but Forever Pipe throughout the plant.”
A huge advantage of Forever Pipe over other solutions is its unique ability to perform thickness checking to monitor wear of the pipes in-service using ultrasonic thickness testing. This is a quick inexpensive exercise using an ultrasound device. This has vastly increased the time between shuts and reduced downtime for visual inspections.
Alcoa has found Forever Pipe to last at least 3 times longer than other hard facing solutions but is equally impressed with the flexibility of sizes and lengths and the ability to have it delivered in such a short lead time. Also stabs, drain points and Ts are simple modifications with Forever Pipe unlike competing solutions.
