Case History---Peer-Reviewed

Background

A failure was observed in an 18″ long radius elbow of ASTM A403 WP 304-WX grade, during site fabrication and erection activities. All the welded fittings used were manufactured from SS 304 plates by the Monaka process [ 1], which involves cold forming of plates and subsequent welding of the formed halves. The fabrication sequence followed by the fitting manufacturer is shown in Fig.  1.
