A new trial by specialist provider of mineral processing and material handling equipment FLSmidth Ludowici and leading global engineering firm Sedgman Limited to extend pipe life has been successfully completed.
The 12-month research and development lined-pipe trial involved lining the internal surface of a co-disposal system’s pipe with 12mm of FLSmidth Ludowici’s WEAR-RESIST compound, which aimed to extend the pipe’s life despite the highly abrasive operating conditions.
Held at the Sonoma Coal Mine, which produces high-quality coking and thermal coal, the trial began in July 2011. The two pipe lengths, which were 300NB x 6000 in length were lined with the FLSmidth Ludowici WEAR-RESIST compound (alumina-based ceramic bead encapsulated in epoxy resin) centrifugally cast into the co-disposal tailing lines, and put on a six-week rotation.
According to Sedgman’s Project Leader, the steel pipe wore at a rate of around 0.5mm per week but the pipe with WEAR-RESIST still had continuity through the pipe wear indicators. Approximately 600,000 tons of plant reject passed through those pipes over the test period.
Over the last 15 years the WEAR-RESIST compound has been successfully used in co-disposal pipes at the Jeebropilly mine on the Moreton field. Sedgman approached FLSmidth Ludowici with the proposal to trial WEAR-RESIST as they wanted to increase the wear life of pipes throughout many of their coal preparation plants.
FLSmidth Ludowici took up the challenge and free-issued the pipes on a research and development project basis.
FLSmidth Ludowici Product Specialist Wear Surfaces, Peter Carseldine explains that the company is keen to expand the areas where WEAR-RESIST can be employed to increase the life of pipe installations.
