Kuzirala chitoliro ntchitochubu chachitsulo chosasinthikaayenera kugwiritsidwa ntchito ngati kuwotcherera, kuwonjezera ntchito pamene olumikizidwa kwa zida, mavavu flanged kapena ulusi kugwirizana.kuwotcherera mpweya ntchito m'mimba mwake zosakwana 5mm, m'mimba mwake kuposa 5mm pogwiritsa ntchito kuwotcherera.Kuwotcherera kwa chitoliro kumagwiritsidwa ntchito kwambiri mufiriji, pokhapokha ngati kuli kofunikira pakuyika ndi kukonza, kugwirizana kwa flanged kapena ulusi kumagwiritsidwa ntchito.Pogwiritsa ntchito ma convex pamwamba pawotcherera flange masikweya kapena flange yooneka ngati impso, polumikizana ndi flange, ma gaskets okhala ndi makulidwe a 1 ~ 3mm asbestosi wamafuta amphira, ndikusintha kwa graphite yokutidwa ndi mafuta.Pamene ulusi kugwirizana, muyenera kugwiritsa ntchito mafuta kapena palafini kuyeretsa mafuta pa ulusi, ndiyeno wokutidwa ndi glycerol kuyanjanitsa gilateni chakudya kapena Teflon tepi ngati chisindikizo kulongedza katundu, analetsa ntchito kutsogolera monga fulakesi mafuta ndi kulongedza chisindikizo.

Freon firiji chitoliro m'mimba mwake ndi zosakwana 25 mm ndi chitoliro mkuwa, pali angapo kugwirizana njira.

(1) zidutswa zamkuwa zomalizidwa.mawonekedwe a mawonekedwe amtundu wa socket, kugwirizana kwa brazing.

(2) zitsulo olumikizidwa ndi brazing mkuwa, annealing ayenera choyamba chitoliro mapeto, ndiyeno kutentha nkhungu ndi zitsulo, m'mimba mwake zitsulo ayenera kukhala wamkulu kuposa awiri akunja a kuyika chubu 0.25 ~ 0.5mm, zitsulo zomveka kuya akhoza kukhala ofanana ndi m'mimba mwake chitoliro, okwera malangizo Kuyang'ana otaya sing'anga.

(3) kugwirizana kwa flange.Malinga ndi kapangidwe ka zinthu ndi zochitika zenizeni, payipi unsembe ntchito angagwiritsidwe ntchito mkuwa ndi mkuwa aloyi chitoliro flange lotayirira flange, kuwotcherera mphete lotayirira flange ndi welded flange, welded flange kugwirizana mawonekedwe.
