1. Izinga lokushisa lokuklama nokucindezela kwesitsha;
2. Izindinganiso zokuxhuma zamavalvu, okokufakwayo, izinga lokushisa, ingcindezi, nezikali zamaleveli ezixhunywe kuyo;
3. Ithonya lokucindezeleka okushisayo ku-flange yepayipi yokuxhuma kumapayipi enqubo (izinga eliphezulu lokushisa, amapayipi ashisayo);
4. Inqubo kanye nezici ezimaphakathi:
Eziqukathi ezingaphansi kwezimo ze-vacuum, lapho idigri ye-vacuum ingaphansi kuka-600mmHg, isilinganiso sokucindezela se-flange yokuxhuma akufanele sibe ngaphansi kuka-0.6Mpa; Uma i-vacuum degree ingu-(600mmHg~759mmHg), izinga lokucindezela le-flange yokuxhuma akufanele libe ngaphansi kuka-1.0MPa;
Eziqukathi eziqukethe imidiya eyingozi eqhumayo kanye nemidiya eyingozi enobuthi obumaphakathi, izinga lokucindezela le-flange yokuxhuma yesiqukathi akufanele libe ngaphansi kuka-1.6MPa;
Eziqukathi eziqukethe imidiya eyingozi kakhulu futhi enobuthi obukhulu, kanye nemidiya ekwazi ukungena kalula, ukulinganisa kokucindezela okulinganiselwe kwe-flange yokuxhuma yesiqukathi akufanele kube ngaphansi kuka-2.0MPa.
Kumele kuqashelwe ukuthi lapho indawo yokuvala ye-flange yokuxhuma yesiqukathi ikhethwa njenge-concave convex noma indawo ye-tenon groove, amapayipi axhumayo atholakala phezulu nasohlangothini lwesitsha kufanele akhethwe njengama-flanges angaphezulu noma ama-groove; Ipayipi elixhumayo elitholakala ngaphansi kwesiqukathi kufanele lisebenzise i-flange ebheke phezulu noma ye-tenon.
