Save your Centrifugal Machinery during Commissioning
MetadataShow full item record
During the commissioning of centrifugal machines (Compressors, steam turbines, pumps, fans etc.), a lack of flushing, inspection and ignorance of critical areas & procedures can lead to major problems, damage, and serious safety issues. These serious issues and damages lead to a delay in startup of the refinery, resulting in large monetary loss & further delay as major spares required to carry repairs may not be available in initial stage. It is possible to prevent such damage by following the procedures and inspections which are discussed in detail in this paper. The tutorial covers the experience and learning derived by the commissioning of more than 5,000 rotating machinery equipment over the past 5 years. The Tutorial will illustrate what can go wrong with centrifugal machinery during commissioning and startup and actual case studies of damage are provided along with the corrective and preventive measures suggested for successful commissioning. A Checklist of Do’s and Don’ts to be followed before and during commissioning is also provided.
