Iisiphethoivame ukusetshenziswa kanye ne-lap joint flange ukwenza indawo yokuxhuma i-weld neck flange, kodwa khumbula ukuthi ngeke isetshenziswe njengewelding intamo flange, futhi abakwazi ukudideka.
IZINHLOBO ZOKUPHELA KWE-STUB
Kunezinhlobo ezintathu ezijwayelekile ze-stub end, okuwuhlobo A, uhlobo B nohlobo C
1. Uhlobo A luyakhiqizwa futhi lwenziwe ngomshini ukuze lufane nezingai-lap joint flange(le mikhiqizo yomibili kufanele isetshenziswe ngokuhlangana).
Izindawo zokukhwelana zinephrofayili efanayo ukuvumela ukulayishwa okushelelayo kobuso be-flare
2.Uhlobo B kufanele lusetshenziswe nama-slip-on flange ajwayelekile
3. Uhlobo C lungasetshenziswa nge-lap joint flange nomaama-slip-on flangesfuthi akhiqizwa ngamapayipi
Kunezinhlobo ezimbili ze-stub end, ezifushane nezinde, futhi ubukhulu bayo obukhulu bungafinyelela amasentimitha angu-48, okungukuthi, amamodeli ahlukahlukene we-DN15-DN1200.
Iphethini emfushane, ebizwa nge-MSS-A stub iyaphela
Iphethini ende, ebizwa ngokuthi i-ASA-A stub iphetha noma isiphetho se-ANSI sobude.
UBUHLE BOKUPHELA KWE-STUB
1. Ukuphela kwe-stub kunganciphisa izindleko eziphelele ze-flange ehlangene yesistimu yepayipi yebanga eliphezulu lezinto ezibonakalayo, ngoba i-lap flange akudingeki isebenzise into efanayo nepayipi kanye nesiphetho esifushane, futhi impahla yebanga eliphansi ingakhethwa. yokufanisa.

ISICELO
1.Isiphetho se-stub, esiwucezu lwepayipi, olunohlangothi olulodwa oluvulekele ngaphandle kanti olunye lulungiselelwa ukushiselwa epayipini elilingana nosayizi webhore, impahla kanye nokuqina kodonga.
2.I-lap joint flange, esetshenziselwa ukuhlanganisa ubude obubili bepayipi ndawonye.
