1. Zita dhayamita DN:
Flangedhayamita rezita zvinoreva dhayamita rezita remudziyo kana pombi ine flange. Iyo dhayamita yezita remudziyo inoreva dhayamita yemukati yemudziyo (kunze kwegaba rine chubhu secylinder), dhayamita rezita repombi rinoreva dhayamita yaro yezita, inova kukosha pakati pedhayamita yemukati nekunze kwepombi, mazhinji acho ari pedyo nepakati pepakati pepombi. Iyo dhayamita yekunze yepombi yesimbi ine dhayamita imwechete yezita yakafanana, uye dhayamita yemukati yakasiyanawo nekuti ukobvu huri kuchinja. 14 - ona tafura 1.

2. Nominal pressure PN:
Nominal pressure igiredhi rekumanikidza rakapihwa chinangwa chekumisa mwero. 14 - ona tafura 2.
3. Yakanyanya kubvumidzwa kumanikidzwa kushanda:
Iyo yezita kudzvinyirirwa mukumanikidza mudziyo flange standard inotemerwa pasi pemamiriro eflange zvinhu16Mn (kana 16MnR) uye tembiricha yekugadzira 200oC. Apo iyoflange zvinhuuye kushanduka kwekushisa, iyo yakanyanya kubvumirwa kushanda kudzvinyirira kweflange kuchawedzera kana kuderera. Semuenzaniso, iyo yakanyanya kubvumirwa kushanda kudzvinyirira kwehuro-refu butt welding flange inoratidzwa muTebhu 14-3.
