Ithebula lesi-2 le-AWWA C207-18 lihlinzeka ngezicaciso ze-Class B ring flange. I-AWWA C207-18 iyindinganiso eshicilelwe yi-American Water Works Association (AWWA) echaza ubukhulu nokubekezelelwa kwama-flange amapayipi ensimbi asetshenziswa ezinhlelweni zokusebenza kwamanzi.
Ama-flange e-Class B amaringi adizayinelwe ukusetshenziswa namapayipi ensimbi ngezinkonzo ezinezingcindezi ezifika ku-86 psi (595 kPa) futhi ngokuvamile asetshenziswa emanzini nasemanzini angcolile. Lawa ma-flange akhiqizwa ngosayizi ohlukahlukene ukuze athwale ububanzi obuhlukahlukene bepayipi.
Ithebula lesi-2 le-AWWA C207-18 lama-flange wendandatho Yekilasi B licacisa ubukhulu obuhlukahlukene njengobubanzi bendilinga yebhawodi, inombolo yezimbobo zebhawodi, ububanzi bembobo yebhawodi, ukujiya kwe-flange, ubude behabhu, nobukhulu obubheke. Lezi zici ziqinisekisa ukuthi ama-flange akhiqizwa ngokwezindinganiso ezidingekayo futhi aqinisekisa ukuqondanisa okufanele nokuvala lapho exhunywe kumapayipi amapayipi.
Ama-flange e-Class B amaringi ngokuvamile akhiqizwa ngensimbi ye-carbon noma insimbi engagqwali futhi akhiwe ukuze amelane nezimo zokusebenza nezidingo zengcindezi yezinhlelo zokusabalalisa amanzi. Ama-flange aklanyelwe ukuhlinzeka ngoxhumano oluthembekile nolungavuziyo phakathi kwamapayipi, ama-valve, nokufakwa kwezinhlelo zokusebenza zamanzi.
Kafushane, izindandatho ze-Class B njengoba kucacisiwe kuThebula 2 le-AWWA C207-18 ziyizingxenye ezibalulekile ezinhlelweni zokusabalalisa amanzi, ezihlinzeka ngoxhumano oluqinile noluvikelekile lwengqalasizinda yamapayipi ezindaweni zokuhlanza amanzi kanye namanzi angcolile.
