1. Kuwotchera mopanda denga:kokha kuwotcherera wosanjikiza wakunja, popanda kuwotcherera wosanjikiza wamkati; Nthawi zambiri amagwiritsidwa ntchito m'mapaipi apakati komanso otsika, kuthamanga kwapaipi komwe kumakhala kosakwana 0.25mpa. Pali mitundu itatu ya kusindikiza pamwambaflat kuwotcherera flange, omwe ndi mtundu wosalala, mtundu wa concave ndi convex ndi mtundu wa tenon groove. Pakati pawo, mtundu wosalala ndi womwe umagwiritsidwa ntchito kwambiri, ndipo mtengo wake ndi wotsika mtengo komanso wotsika mtengo.
2. Kuwotcherera matako:onse mkati ndi kunja zigawo zaflangeayenera welded, zambiri ntchito sing'anga ndi mkulu kuthamanga mapaipi, ndi kuthamanga mwadzina wa payipi ndi pakati 0,25 ~ 2.5mpa. Kusindikiza pamwamba pakuwotcherera flangekugwirizana ndi concave ndi convex, ndipo unsembe ndi zovuta kwambiri, choncho mtengo ntchito, njira unsembe ndi wothandiza zinthu mtengo ndi mkulu.

3. Soketi kuwotcherera:Nthawi zambiri amagwiritsidwa ntchito ngati kuthamanga mwadzina ndikochepera kapena kofanana ndi 10.0MPa, m'mimba mwake mwadzina ndi wocheperako kapena wofanana ndi 40mm mupaipi.
4. Manja omasuka: Nthawi zambiri amagwiritsidwa ntchito mu payipi ndi kuthamanga otsika koma sing'anga zowononga, kotero mtundu uwu wa flange ali ndi mphamvu kukana dzimbiri, ndipo zakuthupi ndi makamaka zosapanga dzimbiri.
Kulumikizana kotereku kumagwiritsidwa ntchito makamaka polumikiza chitoliro chachitsulo, chitoliro chachitsulo, chitoliro chachitsulo chosapanga chitsulo ndivalve ya flange, etc., ndi kugwirizana kwa ndondomeko zipangizo ndi flange zimagwirizananso ndi flange.
