Kungani i-Weld Neck Flange iphoqelekile emapayipini anengcindezi ephezulu ye-Class 2500?

I-Class 2500 imelela esinye sezigaba zengcindezi ezidinga kakhulu ezichazwe ku-ASME B16.5.

Lesi sikhundla sibekelwe izindawo zokusebenza ezinzima kakhulu: ingcindezi ephezulu kakhulu yokusebenza, ukushintsha kwezinga lokushisa okubanzi nokuvamile, ukujikeleza kokushisa okuphindaphindiwe, ukudlidliza kwepayipi, kanye nokukhuphuka kwengcindezi ngezikhathi ezithile.

Kulezi zimo zokusebenza ezinzima, ukuhlangana kwe-flange kufanele kugcine ubuqotho ngaphandle kokuvuza noma ukuqhekeka ngenxa yokukhathala ekusebenzeni isikhathi eside.

Ama-flange e-slip-on, ama-flange e-threaded noma ama-flange e-plate awakwazi ukumelana ngokuthembekile nemithwalo enjalo yomjikelezo wemishini nokushisa.

Lezi zindlela zokwakha zidala izinguquko ezingazelele zobukhulu bogqinsi lwendonga kanye nokukhuphuka okubukhali kwengcindezi khona lapho endaweni yokuhlangana.

Ngaphansi kwengcindezi yomjikelezo kanye nezinga lokushisa, imifantu yokukhathala ivame ukuqala kulezi zindawo ezinengcindezi ephezulu.

I-hub e-tapered ye-WN (Weld Neck) flange ixazulula le nkinga eyinhloko.

Inikeza ukushintsha okubushelelezi, okuhamba kancane kobukhulu bogqinsi lwendonga kusuka emzimbeni wepayipi kuze kufike eringini ye-flange.

Ingcindezi isatshalaliswa ngokulingana futhi idluliselwa kancane kancane kude nempande ye-butt weld, okunciphisa kakhulu ukugxila kwengcindezi endaweni yokuhlangana kwepayipi ne-flange.

Kuma-DN80 Class2500 WN flanges, le mithetho ebalulekile kufanele ilandelwe ngokuqinile:

✅ Ukushaya okugcwele okuqinile kuphela. Ama-flange e-plate-cut noma e-rolled plate fabricated awamukelekile ku-Class2500 critical service, ngoba ukuhamba kwezinhlamvu ze-rolled plate akukwazi ukufana ne-continuous metal fibre yengxenye eyakhiwe ngokushaya.

✅ I-weld ye-butane egcwele ngokuphelele. I-weld ye-butane ihlanganisa ipayipi ne-flange, okwenza kube namandla alinganayo phakathi kwepayipi ne-flange assembly.

✅ Indawo yokufaka uphawu ye-RTJ (Ring Type Joint) icaciswa kabanzi. Umsele owenziwe ngomshini ukhiya i-gasket yensimbi yeringi endaweni, okuvimbela ukukhishwa kwe-gasket ngaphansi kwengcindezi ephezulu nokushintsha kwezinga lokushisa.

✅ Ukuhlolwa kwe-NDT njenge-UT noma i-MT ngokuvamile kuyadingeka ukuze kuqedwe izinkinga ezifihlekile zokwakhiwa.
