Kev kuaj hom yog ib qho kev xeem uas ua tiav thiab nruj heev rau ib lossis ob peb tus qauv piv txwv los xyuas seb qhov kev tsim khoom puas ua tau raws li cov qauv thiab cov lus qhia txog kev siv tshuab. Raws li EN545 tus qauv yuav tsum tau ua:
Yam tsawg kawg ib qho kev qhia tshwj xeeb hauv txhua pawg yuav tsum tau kuaj hom. Thaum qhov kev ua tau zoo ntawm tib qhov loj me sib xyaw ua ke yog raws li cov qauv tsim tib yam, ib qho kev qhia tshwj xeeb tuaj yeem sawv cev rau ib pawg. Yog tiascov yeeb nkab hlau ductileYog tias cov txheej txheem tsim lossis kev tsim khoom hauv ib pawg sib txawv, pawg yuav tsum tau hloov chaw thiab sib koom ua ke. Thaum muaj cov flanges koom nrog, tsawg kawg ib qho kev qhia tshwj xeeb hauv txhua pawg yuav tsum tau kuaj hom, thiab PN kuaj yog tus nqi siab tshaj plaws rau txhua flange. Thaum kev ua tau zoo ntawm tib qhov loj me sib xyaw ua ke yog raws li cov qauv tsim tib yam, ib DN tuaj yeem sawv cev rau ib pawg. Yog tias cov txheej txheem tsim khoom lossis kev tsim khoom hauv ib pawg sib txawv, pawg yuav tsum tau rov qab sib koom ua ke.
cov yeeb nkab hlau ductile uas raug txwv tsis pub sib txuas, cov yeeb nkab hlau ductile sib txuas, cov yeeb nkab hlau ductile sib txuas hom, thawb rau cov yeeb nkab hlau ductile sib txuas,
