对HG 20593—1997标准中PL350-0.6FF法兰有关问题的建议

DISCUSSION ON THE ISSUES OF PL350—0.6FF FLANGE IN THE STANDARD HG20593—1997

通过对酸液罐水压试验渗漏的分析,发现HG 20593—1997标准中PL-FF法兰存在螺栓孔数量偏少,法兰厚度偏厚,提出对HG 20593—1997标准进行修订的建议。

By analyzing the leakage in hydrostatic test of the Acidic Liquid Tank,found that the less numbers of bolt-hole for PL-FF and thicker thickness of the flange is specified in the standard HG20593-1997.So revision is suggested for the relative sections of HG20593-1997 in this article.
