Slurry Pumping & Piping
Yogyakarta | 30 July – 2 August 2013 | IDR 7,000,000.00 per participant
DESCRIPTION
The design of slurry pumping systems is considerably more complex compared to that of “clean fluids”. In addition to this, the information found in the public domain relating to this subject is sometimes “academic” and does not always give the practicing engineer the simple answers he or she needs to solve a particular problem. As a result, consultants who specialise in slurries are often employed even for the less complex slurry pumping design or troubleshooting problems.
WHO SHOULD ATTEND
Consulting Engineers, Process Engineers, Design Engineers, Project Engineers, Slurry Pump & Piping Sales Representatives and anyone who needs to select, specify, commission, install and/or troubleshoot slurry pumping equipment and slurry piping.
