Witness Testing Of API 610 Centrifugal Pumps And API 611 Steam Turbines
MetadataShow full item record
The tutorial outlines the basic concepts and offers some tips on witness testing of API 610 centrifugal pumps and API 611 steam turbines. The section on API 610 pump testing discusses performance, NPSH and mechanical run tests of API 610 centrifugal pumps that are often specified with witness testing. Various parameters that are measured during testing and the related instrumentation are introduced. This section references related paragraphs and tables from ANSI/API Standard 610 (2010). The section on API 611 steam turbine testing covers the mechanical run test and cites the related paragraphs of API Standard 611 (2008). The same section also recommends a few additional tests that could be performed on general purpose steam turbines, if feasible and applicable.
