摘要

To respond to customers' needs for higher grade and higher quality linepipe in recent years, in 2003, JFE Steel's Chita Works carried out a revamp of its 26" medium-diameter ERW pipe mill, in which the maximum wall thickness of API 5LX56 grade (API: American Petroleum Institute) was increased from the former 20.6 mm to 25.4 mm. At the same time, Chita also improved its measurement technology and developed an original quality assurance system, represented by a multiprobe weld seam ultrasonic test (UT) inspection device, with the aim of improving weld seam quality.
