6.1 Scope of Testing and Inspection

NDE testing

Factory acceptance test and procedure includes component information: pump, vessels

visual examination and inspection, and testing of different parts: gears, couplings mechanical

runs. Also subject of inspection should include: dimensional check, installations according to

layout and instructions, constructional inspection, inlet/outlet connections

Performance, function and mechanical running test should be performed according to pre-

defined criteria and procedures and eventually with determining best working pressure under

operating conditions as practical results. Adequacy of pressure control and functionality, and

also considering start-up, shut down, overpressure and failure occurrences should be regarded.

Pressure / pneumatic tests and leakage test.

Eventually repeat NDE after pressure tests

Positive displacement pumps tests include testing of providing requirements due to

pressure/head-flow (volume-speed) at different operating conditions: from start-up to rating

point, also appropriate behavior during shut down and failure occurrence, and comparison of

head-flow characteristic curves with given ones. Considerations should be done regarding

efficiency and finding optimized working conditions: pressure-flow (volume-speed). During

performance and functional test, flow rate and available pressure at discharge should also be

measured and considered as test parameters and additionally pressure-flow curve should be

acquired and considered for optimized rating conditions and best efficiency.






HEN 0000 ME SP 0012 23 of 29

Also stroke control should be performed due to requirements stated before. Performance test

should achieve requirements due to finding appropriate stroke and adjustment for best

efficiency due to design (available) pressure/head-flow and determining the rating point: manual

stroke adjustment.

Pulsation suppression construction inspection and function testing should also be performed.

For discharge pulsation dampeners: pressure tests, appropriate pressure and pressure setting

should be done. Performance and function test should prove appropriate damping under

operating conditions. Proper construction and adjustments should met requirements due to

proper working conditions with adjusting pulsation level. Performance test include also testing

of dampeners during working situations and assuring of satisfiable performance in pre-defined

working pressure-flow (volume-speed) conditions.

Performance test of each pump train should be performed according to data given regarding

pump fluid characteristics: specific gravity, density, viscosity and also design flow-pressure:

discharge and suction pressures, flow constructions

Alignment and vibration tests should be performed according to pre-given procedures and

requirements. Vibration amplitudes should be less than max permissible value (from start-up to

rating point, also during conditions related to max operating loads and shut down).

For coupling, bearings and gear box, mechanical running test should be done regarding

transmitted power and speed-load test. Material hardness tests should also be performed.

Piping, valves, fittings and also bolting should appropriate material and class. Pressure,

function and leakage tests should be done according to pre-defined instructions. Nozzles and

connections load calculations, material certifications, and corrosion considerations with

appropriate material are also important. Design of piping and valves placement is also subject

of inspection and should be reviewed. Inspection check of required and determined connections

and accessories for pump and other parts should be done. Especial connections should be

provided for injection points. Also input/output connections from pump, valves and

connection should be inspected.

LV Motor routine test shall be carried out on each motor .

Noise test should show acceptable sound level.

Factory Acceptance Test / Industrial test / Assembled skid testing should be done according to

API standard. Mechanical running of whole system should be tested and results be compared

with requirements.

Functional acceptance test for each cabinet (All alarms & safety device) including interface shall

be done.
