NDT METHODS FOR PRESSURE VESSELS & HEAT EXCHANGERS
NDT METHODS FOR PRESSURE VESSELS & HEAT EXCHANGERS 𝗛𝗲𝗮𝘁 𝗲𝘅𝗰𝗵𝗮𝗻𝗴𝗲𝗿𝘀 𝘂𝗻𝗱𝗲𝗿 𝘀𝘁𝗿𝗲𝘀𝘀 - 𝗵𝗼𝘄 𝗱𝗼 𝘄𝗲 𝗽𝗿𝗲𝘃𝗲𝗻𝘁 𝗳𝗮𝗶𝗹𝘂𝗿𝗲 𝗯𝗲𝗳𝗼𝗿𝗲 𝗶𝘁 𝘀𝘁𝗮𝗿𝘁𝘀 ? 👉 The answer lies in Non-Destructive Testing (NDT), a set of advanced inspection techniques that identify defects without harming the equipment. Here’s a list of the key NDT methods used in pressure vessel and heat exchanger inspections: ➡️ Ultrasonic Testing (UT) – Uses high-frequency sound waves to detect internal flaws and thickness loss. ➡️ Radiographic Testing (RT) – Employs X-rays/gamma rays to reveal hidden internal discontinuities, especially in welds. ➡️ Magnetic Particle Testing (MT) – Ideal for surface and near-surface cracks in ferromagnetic materials. ➡️ Liquid Penetrant Testing (PT) – Detects surface-breaking flaws in both ferrous and non-ferrous materials. ➡️ Eddy Current Testing (ET) – Excellent for surface and near-surface cracks, especially ...
