1 概况海南某气库1台1000m~3液化石油气球罐2002年7月进行首次开罐内外部检验。在外表面磁粉探伤时发现赤道带和上温带间的环焊缝(BC环缝)存在20多条裂纹,裂纹长度从2mm至60mm不等,磁探打磨后测其深度最深已达4mm,深度超过2mm的裂纹共计9处。该球罐主要技术参数见表1。
An overview of a gas tank in Hainan 1 Taiwan 1000m ~ 3 liquefied petroleum gas tank in July 2002 for the first time inside and outside the open tank inspection. The outer surface of the magnetic particle inspection found that the equatorial zone and the upper temperature zone between the girth weld (BC girth) there are more than 20 cracks, crack length ranging from 2mm to 60mm, after the deepest magnetic dip grinding measured up to 4mm depth greater than A total of 9 crack 2mm. The main technical parameters of the tank in Table 1.
