Yini aukuphela kwe-stubFuthi kungani kufanele isetshenziswe? Ama-Stub Ends angama-butted attings angasetshenziswa (ngokuhlanganiswa ne-lap ehlanganisiwe i-flange) ngenye indlela eshintshashintshayo entanjeni ye-welding entanyeni ukwenza ukuxhumana okuvundliwe. Ukusetshenziswa kwezimbumbulu zeStub kunezinzuzo ezimbili: kunganciphisa izindleko eziphelele zamalunga avuselelayo ezinhlelweni zamapayipi ezintweni eziphakeme ezibonakalayo kumapayipi aphezulu (njengoba i-lap ehlanganisiwe i-flange ayidingi ukuba yinto efanayo yepayipi kanye ne-stub ukuphela kodwa kungaba yibanga elifanayo);Isheshisa inqubo yokufaka, njengoba i-lap ehlanganisiwe i-flange ingashintshwa ukuze lula ukuhambisana kwezimbobo ze-bolt. Ama-Stub Ends ayatholakala ngephethini emfushane nelide (i-ASA kanye ne-MSS Stug Enders), ngosayizi abe ngamasentimitha angama-80.
Izinhlobo Zomphetho weStub
Ama-Stub Ends atholakala ezinhlotsheni ezintathu ezahlukahlukene, okuthiwa "Thayipha a", "uhlobo b" kanye "nohlobo c":
- Uhlobo lokuqala (a) lwenziwa futhi lwenziwa imishini yokufanisa i-flange ehlanganisiwe ye-LAS LASE ehlanganisiwe (imikhiqizo emibili kufanele isetshenziswe ngokuhlanganiswa). Izindawo zokuzalela zinephrofayili efanayo ukuze zivumela ukulayisha okubushelelezi kobuso be-flare
- Uhlobo lwe-Stub Ends B kufanele lusetshenziswe ngama-flanges ajwayelekile
- Uhlobo lwe-C STUB EMNS lungasetshenziswa noma nge-LAP ngokuhlangene noma nge-slip-on flanges futhi akhiqizwa amapayipi
Amaphethini amafushane / amade esitezi se-STUB (ASA / MSS)
Ama-Stub Ends ayatholakala ngamaphethini amabili ahlukile:
- iphethini emfushane, ebizwa ngokuthi yi-MSS-a Stub ephela
- iphethini ende, ebizwa ngokuthi i-ASA - I-Stub Ends (noma isiphetho sobude be-ANSI)
