PUMPS, PIPING AND VALVES JULY 2019 • E&MJ 31 www.e-mj.com • Multiple Windows – Visualize different parts of the mine. • Contamination – Simulate contamina- tion spreading through the model, and "reverse" simulate to fi nd possible source(s) of contamination. • Video – Record a movie of a simulation for convenient playback and review. • Measuring Tool – Select a path on the pipe network and generate a graph of available data (i.e., pressure, fl ow etc.). Control the Flow An integral element of piping system layout is designer cognizance that criti- cal pipeline segments need reliable con- trol mechanisms, usually in the form of valves, that can meet the demands of the application without incurring special maintenance needs, unscheduled down- time or degraded performance during their anticipated service life. A few ex- amples illustrate the wide choice of prod- ucts available to handle everything from everyday transfer of various mining-relat- ed fl uids through industrial-grade plastic piping, to high-pressure pumping and control of large-diameter slurry pipelines. Victaulic recently introduced the Se- ries 906 knife gate valve (906 KGV), claimed to be ideal for smaller-diameter HDPE lines carrying abrasive materials common in mining. It is designed to allow installation and maintenance without the need to disconnect it from the pipeline. "The 906 KGV is an advanced tech- nology that encloses all wear parts into a single seat cartridge kit, which reduces maintenance downtime by up to 95% and generates up to 60% savings in annual maintenance costs," said Mike Prince, product engineer at Victaulic. "We have witnessed our KGVs lasting more than fi ve times longer than alternative products currently on the market." The new valve, according to the com- pany, also improves worker safety, elimi- nating the necessity and subsequent risk for workers, of rigging with heavy chains and pulleys overhead. The 906 KGV joins plain-end HDPE pipe. It is available in sizes ranging from 3 to 8 in. and rated to 150 psi (1034 kPa/10 bar), or the maximum rating of the HDPE pipe, whichever is lower. Corfl ex Engineering in South Africa has been building pinch valves for slurry pipeline applications since 1981. It of- fers units suitable for handling working pressures up to 200 bar (2,900 psi), with standard models up to 500 mm in size and 1,000 mm units available. © 2019 Caterpillar. All Rights Reserved.
