NDT & EQUIPMENT TESTING
Equipment Inspection & Testing Services dengan Certified Methods
Comprehensive inspection & testing services untuk verify equipment integrity, performance, dan compliance. NDT methods, pressure testing, electrical testing, performance verification dengan certified procedure & qualified inspector.
Non-Destructive Testing (NDT) Methods
NDT inspection untuk detect defects tanpa merusak equipment – verify integrity sebelum/setelah repair atau periodic inspection
Visual Testing (VT)
Surface defect, corrosion, crack, weld profile – direct visual atau borescope inspection
Ultrasonic Testing (UT)
Thickness measurement, internal flaw detection, weld quality – pulse-echo atau through-transmission
Magnetic Particle (MT)
Surface/near-surface crack pada ferrous material – wet fluorescent atau dry powder method
Dye Penetrant (PT)
Surface crack detection pada non-ferrous material – visible atau fluorescent penetrant
Pressure & Leak Testing
Verify pressure equipment integrity sesuai code requirement (ASME, API, B31.3)
Hydrostatic Test
- Test medium: Water dengan rust inhibitor (if needed)
- Test pressure: 1.3-1.5× design pressure (per code)
- Hold time: 30 minutes minimum atau per specification
- Acceptance: No leak, no permanent deformation
- Application: Tanks, vessels, piping, heat exchangers
Pneumatic Test
- Test medium: Air atau nitrogen (inert gas)
- Test pressure: 1.1-1.15× design pressure
- Safety: Higher risk – require proper procedure & barricade
- Application: When water test not practical (weight, freezing)
- Leak detection: Soap solution atau ultrasonic detector
Leak Test
- Bubble test: Soap solution untuk detect small leaks
- Pressure decay: Monitor pressure drop over time
- Helium leak test: High-sensitivity leak detection
- Vacuum test: Ammonia vapor atau tracer gas
- Application: Final leak check sebelum operation
Electrical Testing & Commissioning Tests
Motor & Cable Testing
- Insulation resistance (Meg test): Motor winding, cable – verify insulation integrity (≥1 MΩ)
- Winding resistance: Detect shorted turns, connection problem
- Polarization index (PI): Insulation quality assessment (PI ≥2.0 good)
- High potential test (Hi-Pot): Dielectric strength verification
- Phase rotation: Correct phase sequence untuk 3-phase motor
- No-load test: Current, vibration, temperature during no-load run
Panel & Protection Testing
- Contact resistance: Busbar, terminal connection (low resistance = good contact)
- Grounding resistance: Earth ground system (≤5 Ω required)
- Circuit breaker test: Trip characteristic, contact resistance
- Relay calibration: Overload relay, protection relay setting verification
- Control circuit test: Interlocks, sequencing, alarm function
- Power quality: Voltage, frequency, harmonics, power factor
Equipment Performance Testing
Pump Performance Test
Flow, head, power measurement – verify pump curve, efficiency, NPSH margin
Heat Exchanger Test
Heat duty, LMTD, approach temp, pressure drop – verify thermal performance
Vibration Analysis
Amplitude, frequency, phase – detect imbalance, misalignment, bearing defect
Control System Test
Loop response, accuracy, stability – PID tuning, setpoint tracking, disturbance rejection
