This article describes about centrifugal compressor vibration testing, analysis and limits based on API Std. 617
The centrifugal compressor testing article explains about compressor mechanical running test and compressor aerodynamic performance test, impeller overspeed, casing inspection, gas leak test etc.
The API 617 requires the Centrifugal Compressor Aerodynamic testing being performed based on the requirement of ASME PTC 10 -1997. This article provides you with information about this test.
The pump impeller dynamic balancing is done based on API 610 requirements. The standard requires the balancing be performed based on ISO 1940-1 to the Grade G2.5
The pump casing hydrostatic test is performed after successful completion of the pump casing inspection.
The pump casing inspection starts with material inspection, nondestructive testing and ends with hydrostatic testing.
Pump mechanical run test is performed for 4 hours to proves pump work in stable condition and all variables are within acceptance range.
The pump net positive suction head test (NPSH test) isperformed to measure the ability of the pump to avoid cavitation in the inlet section of the pump.
The pump vibration testing is performed during performance test at different flowrates and also during the mechanical running test at the rated flow.
This content provides a sample pipe three layer polyethylene coating specification and highlights important inspection and testing requirements.
The valve backseat test is performed in the valve with backseat feature and it is similar to the valve shell test and the valve shall be fully opened and packing gland shall be loose.
In valve seat leak test one side (valve inlet or outlet) shall be subjected to the hydrostatic pressure and amount of leakage shall be measured on the opposite side of the valve.
The valve shell test is conducted by valve manufacturer and based on the requirements of API STD 598 ( Valve Inspection and Testing).
The welding map is the equipment sketch which identifies the welding seams and indicates what WPS shall be used for that particular welding seam.
The Nondestructive testing map identifies NDE method and location of the application on the equipment sketch.
The Nonconformity report is a supplementary document for source inspection report when a nonconformance being observed.
Material test report or Mill test report certifies that the chemical analysis and mechanical properties are in conformance with the specified specification.
