Yintoni naisiphelo sestubkwaye kutheni kufuneka isetyenziswe?Iziphelo ze-Stub zizifakelo ze-buttweld ezinokuthi zisetyenziswe (ngokudityaniswa ne-lap joint flange) endaweni yokuwelda iiflange zentamo ukwenza udibaniso olune-flanged.Ukusetyenziswa kweziphelo zestub kuneenzuzo ezimbini: kunokunciphisa ixabiso lilonke lamalungu ane-flanged kwiinkqubo zemibhobho kumanqanaba aphezulu ezinto (njengoko i-lap joint flange ingafuneki ukuba ibe yinto enye yombhobho kunye ne-stub end kodwa ingaba ibakala elisezantsi);ikhawulezisa inkqubo yokufakela, njengoko i-lap joint flange inokujikelezwa ukuququzelela ukulungelelaniswa kwemingxuma ye-bolt.Iziphelo ze-Stub zifumaneka kwipatheni emfutshane kunye nende (i-ASA kunye ne-MSS stub ends), ngobukhulu ukuya kwi-intshi ezingama-80.
IINTLOBO ZOKUPHELA KWE-STUB
Iziphelo zestub zifumaneka kwiindidi ezintathu ezahlukeneyo, ezibizwa ngokuba "uHlobo A", "uHlobo B" kunye "noHlobo C":
- Uhlobo lokuqala (A) luyenziwa luze lwenziwe ngoomatshini ukuze lungqinelane neflange esemgangathweni yokuxhasa umjikelo (ezi mveliso zimbini kufuneka zisetyenziswe ngokudityaniswayo).Umphezulu wokukhwelana unenkangeleko efanayo ukuvumela ukulayishwa okugudileyo kobuso obudangatye
- Iziphelo ze-Stub zohlobo B kufuneka zisetyenziswe kunye ne-standard slip-on flanges
- Iziphelo ze-C stub zingasetyenziswa mhlawumbi ngelap joint okanye i-slip-on flanges kwaye zenziwe ngemibhobho.
IPHEPHA EMFUTSHANE/EMDE ISIPHELO (ASA/MSS)
Iziphelo zestub zifumaneka kwiipateni ezimbini ezahlukeneyo:
- ipateni emfutshane, ebizwa ngokuba yi-MSS-A stub iphela
- ipateni ende, ebizwa ngokuba yi-ASA-A stub ends (okanye ubude be-ANSI ekupheleni)
