1. Ma valve odulidwa ndi oyenerera mapaipi kapena zipangizo zomwe zimakhala ndi kutentha kwambiri komanso kupanikizika kwakukulu. Monga zomera matenthedwe mphamvu, zomera mphamvu nyukiliya, kutentha ndi mkulu kuthamanga mapaipi a petrochemical kachitidwe.
2. Mavavu a globe amagwiritsidwa ntchito m'mapaipi pomwe kukana kwa convection sikufunikira kwenikweni. Ndiko kuti, kutaya kupanikizika sikuganiziridwa.
3. Mavavu a singano, ma valve opangira zida, mavavu a zitsanzo ndi ma valve opanikizika a singano ndizosankha kwa ma valve ang'onoang'ono.
4. Pali kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. Kwa mapaipi okhala ndi njira yochepera 50 mm, valavu yodulidwa iyenera kusankhidwa.
5. Kuthamanga kwa angular globe valve kapena kuthamanga kwa angular throttle valve ndi kuthamanga kwadzina PN160 16 MPa kapena PN320 32 MPa ayenera kusankhidwa kwa feteleza ang'onoang'ono ndi akuluakulu opanga mafakitale opanga mafakitale.
6. Mu msonkhano wa desiliconization ndi payipi ya coke-prone ya alumina Bayer ndondomeko, n'zosavuta kusankha valavu yapadziko lonse lapansi kapena valavu yowonongeka yomwe ili ndi thupi lopatukana la valve, mpando wopezeka ndi carbide kusindikiza awiri.
7. M'mapulojekiti operekera madzi ndi kutentha pakumanga m'matauni, mapaipi odziwika amadutsa ang'onoang'ono, ndipo mavavu a globe, ma valve owerengera kapena ma valavu a plunger amatha kusankhidwa, monga mapaipi omwe mapaipi mwadzina amadutsa osakwana 150 mm.
