Tafura 2 yeAWWA C207-18 yeClass B ring flanges inotsanangura zviyero zvakasiyana senge dhayamita yebhaudhi, huwandu hwemaburi ebhoti, dhayamita yebhoti, ukobvu hweflange, hub kureba, uye mativi akatarisana. Aya maratidziro anovimbisa kuti maflange anogadzirwa kune anodiwa zviyero uye anovimbisa kurongeka kwakaringana uye chisimbiso kana akabatana nemapombi masisitimu.
Kirasi B mhete dzemhete dzinowanzo gadzirwa kubva kabhoni simbi kana simbi isina tsvina uye dzakavakwa kuti dzimire nemamiriro ekushanda uye kumanikidzwa zvinodiwa zvemafambisirwo emvura. Iwo maflange akagadzirwa kuti ape yakavimbika uye isina-inodonhedza kubatana pakati pemapombi, mavharuvhu, uye fittings mumashandisi emvura.
Muchidimbu, Class B ring flanges sezvakatsanangurwa muTable 2 yeAWWA C207-18 zvinhu zvakakosha muhurongwa hwekugovera mvura, zvinopa kubatana kwakasimba uye kwakachengeteka kwezvivakwa zvepombi mumvura uye nzvimbo dzekuchenesa mvura.
