Yintoni iisiphelo sestubkwaye kutheni kufuneka isetyenziswe? Iziphelo ze-stub zizixhobo zokugquma ezingasetyenziswa (kunye ne-lap joint flange) endaweni yokuwelda ii-neck flanges ukwenza uqhagamshelo olu-flanged. Ukusetyenziswa kweziphelo ze-stub kuneengenelo ezimbini: kunokunciphisa iindleko zizonke zee-flanged joints kwiinkqubo zepayipi kwiindidi zezinto eziphezulu (njengoko i-lap joint flange ingafuneki ukuba ibe yinto efanayo yombhobho kunye ne-stub end kodwa inokuba yinqanaba eliphantsi);Iyakhawulezisa inkqubo yokufakela, njengoko i-lap joint flange ingajikeleziswa ukuze kube lula ukulungelelanisa imingxuma yebholiti. Iziphelo ze-stub zifumaneka ngepateni emfutshane nende (i-ASA kunye ne-MSS stub ends), ngobukhulu obufikelela kwi-intshi ezingama-80.
IINTLOBO ZOKUPHELA KWESIQINI
Iziphelo ze-stub zifumaneka ngeentlobo ezintathu ezahlukeneyo, ezibizwa ngokuba yi-“Type A”, “Type B” kunye ne-“Type C”:
- Uhlobo lokuqala (A) lwenziwa kwaye lwenziwa ngomatshini ukuze luhambelane neflange engasemva edibeneyo yomqolo (ezi mveliso zimbini kufuneka zisetyenziswe kunye). Imiphezulu yokudibana ineprofayili efanayo ukuvumela umthwalo ogudileyo wobuso bokuqaqamba.
- Iziphelo ze-stub type B kufuneka zisetyenziswe nee-flanges ezisemgangathweni ezityibilikayo
- Iziphelo ze-Type C stub zingasetyenziswa nokuba zine-lap joint okanye ii-slip-on flanges kwaye zenziwe ngeepayipi
ISIQEPHU ESIFUTSHANE/ESIDE SESIQEPHU (ASA/MSS)
Iziphelo ze-stub zifumaneka kwiipateni ezimbini ezahlukeneyo:
- ipateni emfutshane, ebizwa ngokuba zi-MSS-A stub ends
- ipateni ende, ebizwa ngokuba zi-ASA-A stub ends (okanye i-ANSI length stub end)
