适用范围
GB/T 22091-2008《55°密封管螺纹量规》分为二个部分,本部分为GB/T 22091-2008的第1部分,修改采用ISO 7-2:2000《用螺纹密封的管螺纹 第2部分:用极限量规验收》(英文版)。 GB/T 22091的本部分规定了55°密封管螺纹量规的设计、尺寸和制造公差、检验、标记等。
本部分规定的量规体系1)适用于检验(GB/T 7306.1-2000规定的圆柱内螺纹和圆锥外螺纹)。 本部分与ISO 7-2:2000的差异如下:
——与GB/T 7306.1-2000对应,修改了标准名称;
——增加第4章,用表格形式阐述了量规名称和代号、功能、特征及使用规则(本版的第4章);
——符号、量规设计、量规尺寸和制造公差、量规检验、量规标记的章节重新编排(ISO 7-2:2000的4、5、7.1、7.2、7.3;本版的第5章~第9章);
——螺纹牙底、螺纹倒角的章节重新编排(ISO 7-2:2000的7.1.1.1a)和b),7.1.1.1第3段;本版的6.6、6.7)
——量规使用和螺纹的检验纳入附录A(ISO 7-2:2000的第6章;本版的附录A)。
