One of the major benefits in doing your own estimates, rather than turning everything over to a manufacturer, is that you develop a better understanding…

A full-load, full-pressure, full-speed (FLFPFS) test is often called for when the compressor train is in gas injection service or other services where the discharge…

The complete-unit test is also called a “String” test. It consists of coupling up all the components and auxiliaries of a compressor train, and running…

This test is the same as Class II except that compressibility factors are applied along with changes in “k” value from suction to discharge. In…

The test gas is different than the specified gas, and in the reduction of test data it is assumed that the test gas and the…

The test gas used is the same as the actual gas specified. The pressures are essentially the same as those specified. In general, this class…

The aerodynamic performance of a stage, of a section, or of a complete casing can be evaluated with an optional test using the procedures covered…

This test comes after the four-hour spin test, and is conducted at maximum seal design pressure (usually settling-out pressure) at zero speed with the seal…

The four-hour mechanical spin test is a standard test for most vendors. It is also specified in API 617 and in Company Specification CMP-MS-1876. The…

The principal inspection points are listed below in the normal manufacturing sequence. The cost of testing is usually added to the purchase cost in a…
