FLANGE INTSHAYELELO

Iinkcukacha ngokwasemzimbeni
Okokuqala nokuphambili, i-flange kufuneka ifake umbhobho okanye izixhobo ezilungiselelwe yona.Iimpawu ezibonakalayo zeeflange zepayipi ziquka imilinganiselo kunye nemilo yoyilo.

Imilinganiselo yeFlange
Ubungakanani bomzimba kufuneka bucaciswe ukwenzela ubungakanani beeflange ngokuchanekileyo.

Idayamitha yangaphandle (OD) ngumgama ophakathi kweencam ezimbini ezichaseneyo zobuso beflange.
Ukutyeba kubhekisa kubukhulu bomphetho wangaphandle oncamathelayo, kwaye akubandakanyi indawo yeflange ebambe umbhobho.
Idayamitha yesangqa seBolt ubude ukusuka kumbindi womngxuma webholithi ukuya kumbindi womngxuma ochasayo.
Ubungakanani bombhobho ngumbhobho weflange ohambelana nobungakanani bombhobho, owenziwe ngokubanzi ngokwemigangatho eyamkelekileyo.Ngokuqhelekileyo kucaciswa ngamanani amabini angenayo i-dimensional, ubungakanani bombhobho oqhelekileyo (NPS) kunye neshedyuli (SCH).
Ubungakanani begama elibiyelweyo yidayamitha yangaphakathi yesiqhagamshelo seflange.Xa uvelisa kwaye ulandelela naluphi na uhlobo lwesixhumi sombhobho, kubalulekile ukufanisa ubungakanani bebhobho yeqhekeza kunye nobukhulu bombhobho wokukhwelana.
Ubuso beFlange
Ubuso be-Flange bunokwenziwa kwinani elikhulu leemilo eziqhelekileyo ezisekelwe kwiimfuno zoyilo.Eminye imizekelo ibandakanya:

Umcaba
Ubuso obuphakanyisiweyo (RF)
Umdibaniso wodidi lweringi (RTJ)
O-ring groove
Iindidi zePipe Flanges
Iiflange zombhobho zinokwahlulwa zibe ziintlobo ezisibhozo ezisekelwe kuyilo.Ezi ntlobo ziyimfama, i-lap joint, i-orifice, ukunciphisa, i-slip-on, i-socket-weld, i-threaded, kunye ne-weld neck.

Iiflange ezingaboniyo ziipleyiti ezingqukuva ezingenaziko ezisetyenziselwa ukuvala iziphelo zemibhobho, iivalvu, okanye izixhobo.Bancedisa ekuvumeleni ukufikelela lula kumgca xa sele utywiniwe.Zingasetyenziselwa uvavanyo loxinzelelo lokuhamba.Iiflange eziyimfama zenziwe ukuba zilungele imibhobho esemgangathweni kuzo zonke iisayizi kumazinga aphezulu oxinzelelo kunezinye iintlobo zeflange.

Iiflange ezidityanisiweyo zeLap zisetyenziswa kwimibhobho efakelwe umbhobho oqhawukileyo okanye ngeziphelo zesinqe ezidibeneyo.Bayakwazi ukujikeleza umbhobho ukuvumela ukulungelelaniswa okulula kunye nokuhlanganisa imingxuma yebholiti nasemva kokuba i-welds igqityiwe.Ngenxa yolu ncedo, i-lap joint flanges isetyenziswa kwiinkqubo ezifuna ukuchithwa rhoqo kweeflange kunye nombhobho.Ziyafana neeflange ezityibilikayo, kodwa zineradiyasi egobileyo kumbhobho kunye nobuso ukuze zivumelane nesiphelo sesikhondo esihlangeneyo.Imilinganiselo yoxinzelelo lwe-lap joint flanges iphantsi, kodwa iphezulu kune-slip-on flanges.

Iiflange ezityibilikayo ziyilelwe ukuba zityibilike ekupheleni kwemibhobho emva koko zidityaniswe kwindawo yazo.Babonelela ngokulula kunye nokufakwa kweendleko eziphantsi kwaye zilungele izicelo zoxinzelelo oluphantsi.

Iiflange ze-socket weld zilungele ubungakanani obuncinci, imibhobho yoxinzelelo oluphezulu.Ukwenziwa kwazo kuyafana nokutyibilika kwiiflange, kodwa uyilo lwangaphakathi lwepokotho luvumela ukuzala okugudileyo kunye nokuhamba kolwelo olungcono.Xa i-welded ngaphakathi, ezi flanges nazo zinamandla okudinwa 50% mkhulu kune-double welded slip-on flanges.

Iiflange ezinemisonto ziintlobo ezikhethekileyo zeflange yombhobho enokuthi ifakwe kumbhobho ngaphandle kwe-welding.Ziyadityaniswa kwibhore ukuze zitshatise umsonto wangaphandle kumbhobho kwaye ziyacolwa ukwenza itywina phakathi kweflange kunye nombhobho.Iiweld zetywina nazo zinokusetyenziswa kunye noqhagamshelo olunemisonto ukuqinisa okongeziweyo kunye nokutywinwa.Zisetyenziswe kakuhle kwiibhobho ezincinci kunye noxinzelelo oluphantsi, kwaye kufuneka zigwenywe kwizicelo ezinomthwalo omkhulu kunye neetorque eziphezulu.

I-welding neck flanges ine-hub ye-tapered ende kwaye isetyenziselwa izicelo zoxinzelelo oluphezulu.I-hub ye-tapered idlulisela uxinzelelo ukusuka kwi-flange ukuya kumbhobho ngokwayo kwaye inika ukuqiniswa kwamandla okuchasene ne-dishing.
