Are there any limitations regarding magnetic particle testing of takeover fillet welds?
Thread Content
Consultation: Magnetic particle testing for butt welds on fittings. Is there any regulation stating that fittings with small diameters cannot be tested using magnetic particles? All diameters can be made as well. Thank you

It depends on the medium, the requirements specified in the design, as well as the material. Generally, for carbon steel fittings with a diameter larger than DN250, ultrasonic testing or magnetic particle testing is used
According to standard requirements, there are generally no restrictions; we have worked with DN25 sizes
