A failed Johnson screen was sent to the laboratory for analysis. The screen was found to have failed at the flange hub – screen joint. Analysis showed that the failure was due to inadequate welding of the flange hub with the ribs/stiffeners of the screen. The failure was by sudden overload. There were no indications of delayed failure like fatigue or stress corrosion cracking. Semi-quantitative analysis by EDX showed that the helical coil of the screen was made of SS 304 steel while the ribs/stiffener were made of SS 316 steel.
