从2009年《固定式压力容器安全技术监察规程》(以下简称“固容规”)的颁布到GB150.1~4-2011《压力容器》的实施,笔者通过对无损检测相关条款变化的对比,加深了对新标准的理解。1对原材料无损检测要求1.1钢板逐张超声检测要求(见表1)表1钢板逐张超声检测从表1看到,新版GB150有两个突出的特点:一是检测级别要求普遍提高;二是对个别钢种需逐张超声检测的板厚下限有所放宽。
From the promulgation of the Regulations on the Supervision of Safety of Fixed Pressure Vessels (hereinafter referred to as the “Regulation of Solid Capacities”) to the implementation of “Pressure Vessels” of GB150.1 ~ 4-2011 in 2009, the author passed the revision of the relevant provisions of nondestructive testing Contrast, deepened the understanding of the new standard. 1 on the non-destructive testing requirements of raw materials 1.1 sheet by sheet ultrasonic testing requirements (see Table 1) Table 1 sheet by sheet ultrasonic testing Table 1 shows that the new version GB150 has two outstanding features: First, the level of detection generally improve; Second For individual types of steel sheet by sheet by ultrasonic testing of the lower limit has been relaxed.
