Yintoni iiflange ezingaboniyo?

I-flange eyimfama yipleyiti engqukuva enazo zonke imingxuma yokuvuthela eyimfuneko ngaphandle komngxuma ophakathi. Ngenxa yolu phawu, iiflange ezingaboniyo zihlala zisetyenziselwa ukutywina iziphelo zeenkqubo zemibhobho kunye nokuvuleka kweenqanawa zoxinzelelo. Bakwavumela ukufikelela lula ngaphakathi kombhobho okanye inqanawa emva kokuba ivaliwe kwaye kufuneka iphinde ivulwe.

Ngaphandle kweflange eyimfama, ukugcinwa kunye nokulungiswa kombhobho kuya kuba nzima. Ukuhamba kuya kufuneka kumiswe kwisivalo esikufutshane, esinokuba ziikhilomitha ukusuka kwindawo yokulungisa. Ukongeza, iivalve ziyabiza kwaye zithande ukuncamathela. Umbhobho unokutywinwa ngeflange eyimfama ngexabiso eliphantsi kakhulu. Iiflange ezingaboniyo zisetyenziswa ngokuqhelekileyo kwi-petrochemical, ipayipi, i-utility kunye namashishini okucoca amanzi, phakathi kwabanye.

I-Blind Flange (BF) licandelo lemibhobho elisetyenziselwa ukuvala okanye ukutywina isiphelo sombhobho, ivalve, isitya okanye itanki. Xa isetyenziswe ekupheleni kombhobho, isitya okanye itanki, inikeza ukufikelela okulula okuvulekileyo ukwenzela ukwandiswa okuqhubekayo kombhobho. I-flange eyimfama iphantsi koxinzelelo olukhulu kunanoma yiyiphi enye i-flange kuba umsebenzi wayo oyintloko kukukhawulela uxinzelelo lombhobho.

Iiflange ezingaboniyo - i-BV efinyeziweyo - isetyenziswa ngokubanzi kuwo onke amashishini apho kusetyenziswa imibhobho. Zifumaneka kuzo zonke iintlobo zobuso (RTJ, Ubuso obuphakanyisiweyo kunye neFlat Face) kunye nemigangatho yoxinzelelo. Nangona ingeyombono ilungileyo kuninzi lwemibhobho, imfama inokubekwa phakathi kweeflange ezimbini ukuthintela ukuhamba. Umyili kufuneka asebenzise imfama xa ezama ukuthintela okwethutyana ukuhamba kombhobho. I-flange eyimfama ibekwe ekupheleni kwevalve ukukhusela ulwelo lwenkqubo ukuba lungaphumi ukuba ivalve ivulwe ngempazamo.
