Non-destructive testing (NDT) of A213 Stainless Steel Welded Pipes

Non-destructive testing (NDT) includes methods such as ultrasonic testing (UT), radiographic testing (RT), dye penetrant testing (PT), and magnetic particle testing (MT).

1. Radiographic Testing

Radiographic testing is a method of flaw detection that utilizes the penetration and attenuation properties of radiation in materials. Depending on the type of radiation used, it can be divided into three categories: X-ray radiography, gamma-ray radiography, and high-energy radiography. Each type of radiographic testing has different methods for displaying defects, including ionization, fluorescent screen observation, photography, and industrial television. Radiographic inspection is primarily used to detect internal defects such as cracks, incomplete penetration, porosity, and slag in welds.

2. Ultrasonic Testing

Ultrasonic waves propagate through metals and other homogeneous media, and reflections occur at interfaces between different media. Therefore, ultrasonic testing can be used to inspect internal defects. Ultrasonic testing can detect defects in any welding material and any part of the structure, and it can sensitively locate defect positions. However, it is relatively difficult to determine the nature, shape, and size of defects using ultrasonic testing alone. Therefore, ultrasonic testing is often used in conjunction with radiographic testing.

3. Magnetic Particle Testing

Magnetic particle testing detects defects by utilizing the magnetic flux leakage generated by magnetizing ferromagnetic A213 stainless steel pipes. Depending on the method of measuring magnetic flux leakage, it can be divided into magnetic particle inspection, magnetic induction inspection, and magnetic recording inspection, with magnetic particle inspection being the most widely used.

Magnetic particle testing can only detect defects on the surface and near-surface of magnetic A213 stainless steel pipes. It can only provide quantitative analysis of defects, and the nature and depth of defects can only be estimated based on experience.

4. Dye Penetrant Testing

Dye penetrant testing utilizes the permeability of certain liquids to discover and display defects. It includes two methods: color inspection and fluorescent inspection, which can be used to inspect the surface defects of both ferromagnetic and non-ferromagnetic materials.
