CaliberiflangeUkuwelda iflange kunye neziphelo zokuwelda ezimpundu zixhaphake kakhulu iflange ephothiweyo ayikho kwimveliso yokwenyani kunye neentengiso zedayamitha enkulu, okanye iimveliso zokuwelda ezisicaba zibalwa ngomlinganiselo wokuwelda osicaba obubanzi beflange kunye ne-butt welding yesakhiwo esikhulu seflange. kwaye ukusetyenziswa koluhlu kwahlukile, kunokubonisa iimpawu kunye neenzuzo zokwahluka, ngoko xa ukusetyenziswa kufuneka kusetyenziswe ngokoluhlu olwahlukileyo, ukuqinisekisa ukuba i-flange idlala indima ebalulekileyo ye-welding flat flat. i-flange enobunkunkqele obuhlwempuzekileyo, ilungele uxinzelelo lwe-p 4 mpa izihlandlo;
Kukho iindidi ezintathu zomphezulu wokutywina weflange: umphezulu wokutywina wenqwelomoya, olungele iimeko ezingeyotyhefu zaphakathi kunye noxinzelelo oluphantsi; Umphezulu weconcave kunye neconvex yokutywina, ilungele iimeko zoxinzelelo oluphezulu kancinane; Umphezulu wokutywina weMortise, ulungele ithuba lokutsha kunye nokudubula. medium enetyhefu kunye noxinzelelo oluphezulu, ububanzi enkulu flange collocation kunye fasteners ezisetyenziswa kwisicelo, oku kulandelayo wathi isicelo iimpawu ezimbini: okokuqala iimpawu mechanical of isimbo ububanzi flange ububanzi. Ifanele ibe ecaleni kwendlela yokuqengqeleka emva konyango lobushushu kwindawo engenanto yokubiwa, ngoko ke indawo engenanto isikiweyo: ukuba indawo engenanto ayikho ngaphezu kwe-40 mm ububanzi, kufuneka kubekho embindini wesampulu; ngaphezu kwe-40mm, emva koko i-equilong-double-head stud kunye ne-full-thread stud esampulwe embindini kwikota yobubanzi iya kuvavanywa ngokweebhetshi kwaye iindongomane ziya kuvavanywa ngokweebhetshi ukuqina; imathiriyeli ekrwada esetyenziselwa iziqhoboshi ezikhethekileyo iya kuba nesiqinisekiso sokufaneleka somenzi.

I-Flange zizibophelelo zokuqinisa kunye nokusetyenziswa ngokubanzi kweendawo zoomatshini zisetyenziswa ngokubanzi zonke iintlobo zezixhobo zoomatshini izithuthi isixhobo senqanawa yesakhiwo senqanawa yezixhobo zokwakha ibhulorho kaloliwe kunye nokubonelela okunje apha ngasentla, unokubona zonke iintlobo zeziqhoboshi, luphawu lokuchazwa kweentlobo ezahlukeneyo. ezahlukeneyo, ukusebenza ngeenjongo ezahlukeneyo, kunye nothotho olusemgangathweni lokuphangalalisa ubukhulu obukhulu beflange uhlobo lwesidanga kwakhona iziqhoboshi ezikhethekileyo, kufuneka ngokwenani lokuhlolwa kwesampulu emva konyango lobushushu, Iziphumo zohlolo ziyakuthobela izibonelelo ezifanelekileyo, kwaye ziya kuqinisekisa ukuba iimpawu zomatshini wemveliso azikho ngaphantsi kokwenziwa kwemeko yesampulu.Zonke izixhobo ezisetyenziselwa iiflange ezinodayamitha ezikhulu ezinoxinzelelo lwe-PN ezingekho ngaphantsi kwe-10.0MPa ziya kuhlolwa ngu i-particle magnetic ngokokuhlolwa okungonakalisi kwe-JB 4730-1994 iinqanawa zoxinzelelo nganye nganye. Emva kokuhlolwa, akuyi kubakho ngxaki kwimveliso, kwaye iya kuhlangabezana neemfuno zeeflanges ezinobubanzi obukhulu be-forgings yesibini.
