ASME B 16.5(突面)RF法蘭尺寸表 |
點(diǎn)擊次數(shù):7670 來源網(wǎng)站:http://www.51kqysj.com/ProList/T141 發(fā)布時(shí)間:2016-10-09< |
ASME B 16.5(突面)RF法蘭尺寸表
目前,國際上管法蘭標(biāo)準(zhǔn)概括起來主要存在著兩個(gè)體系:即歐洲法蘭體系和美洲法蘭體系。歐洲法蘭體系以德國和前蘇聯(lián)管法蘭為代表;美洲法蘭體系美國ANSI管法蘭為代表;這兩個(gè)體系的法蘭尺寸彼此不能互換;我國的石油化工大多是20世紀(jì)50年代按前蘇聯(lián)模式建立起來,因此,JB標(biāo)準(zhǔn)系列靠近歐洲法蘭體系。目前,我國鋼管標(biāo)準(zhǔn)存在著兩套外徑系列的管子規(guī)格,一套為“小外徑”管;另一套為“大外徑”管。美洲法蘭體系美國ANSI管法蘭公稱直徑及匹配的管子系列尺寸見下表所示。
