Скачать или смотреть Piping Engineering & Oil/Gas Interview, ASME B31.1/B31.3, API, ASME IX Welding, Hydrotest, NDT,QA/QC

📘 Slide-by-Slide Description With Easy Formulas

⭐ Slide 1 — Material Selection & Codes

Key Content:
A106 → high temperature
A53 → low-pressure
SS304/316 → corrosion service
Codes → ASME B31.1, B31.3, API 5L, SAES-L-XXX

Formula (copy/paste):
Pipe Thickness = (P × D) / (2 × S × E)

⭐ Slide 2 — Welding & NDT (ASME IX)

WPS / PQR / WPQ requirements
NDT: RT, UT, PT, MT

Formula:
Heat Input = (Volts × Amps × 60) / Travel Speed

⭐ Slide 3 — Hydrotest Procedure

Test limits, blinds, fill/vent/pressurize/hold

Formula:
Test Pressure = Design Pressure × 1.5

⭐ Slide 4 — QA/QC Workflow & Troubleshooting

Heat numbers, weld map, NCR, punch list
Leak causes: poor root, misalignment

Formula:
Minimum Slope = 1 : 100

⭐ Slide 5 — Interview Example (Easy Answers)

Weld defects → PT/RT/UT/MT
SS316 → chloride service
Leak causes → root, electrode, contamination

Formula:
Corrosion Allowance = Required Thickness – Calculated Thickness
