Ukuqulunqwa kunye nokusetyenziswa koluhlu lweeflange eziqhelekileyo
Iiflange ziyinxalenye ebalulekileyo yamashishini ahlukeneyo kwaye ziyinxalenye ebalulekileyo ekuhlanganiseni iinkqubo zemibhobho. Zisetyenziselwa ukudibanisa iipayipi, iivalve kunye nezinye izixhobo zokwenza umnatha wombhobho. Uluhlu lweemilo zeflange ezisemgangathweni kunye nokusetyenziswa zidlala indima ebalulekileyo ekuqinisekiseni imfezeko kunye nokusebenza kakuhle kwezi nkqubo.
Ukwenziwa kweeflange eziqhelekileyo kubandakanya iinkqubo ezininzi eziphambili. Eyona ndlela iqhelekileyo kukuphosa, apho i-flange yenziwe ngokufaka amandla oxinzelelo kwintsimbi evuthayo engenanto. Le nkqubo ivelisa i-flange eyomeleleyo kunye neyomeleleyo kunye nesakhiwo sengqolowa efanayo. Enye indlela i-machining, apho i-flange yenziwe ngokusebenzisa izixhobo zokusika ukususa izinto ezivela kwi-workpiece yensimbi. Le nkqubo yenza ukuba ulawulo lwe-dimensional oluchanekileyo kunye nokugqitywa komphezulu. Ukongeza, iiflange zisenokwenziwa ngokuphosa, apho isinyithi esinyibilikisiweyo sigalelwa kwi-mold ukuze yenze imo efunekayo.
Iiflange eziqhelekileyo zifumaneka kwiindidi ezahlukeneyo zobukhulu, izixhobo kunye noxinzelelo loxinzelelo ukuze zihambelane nezicelo ezahlukeneyo. Zifumaneka kwiindidi ezahlukeneyo ezifana ne-butt weld flanges, i-slip sleeve flanges, i-socket weld flanges, i-threaded flanges kunye neeflange ezingaboniyo, uhlobo ngalunye lwenzelwe iimfuno ezithile zokusetyenziswa. Iiflange eziqhelekileyo zisetyenziselwa ioli kunye negesi, i-petrochemical, ukuveliswa kwamandla, unyango lwamanzi kunye namanye amashishini.
Kwishishini leoli kunye negesi, iiflange eziqhelekileyo zisetyenziselwa ukudibanisa imibhobho, iivalve kunye nezixhobo kwiindawo zokucoca, iiplatifomu ezingaselunxwemeni kunye nezibonelelo zokuhambisa. Badlala indima ephambili ekuqinisekiseni uthutho olukhuselekileyo nolusebenzayo lwemveliso yeoli negesi. Kwishishini le-petrochemical, iiplanti zokucubungula imichiza zisebenzisa iiflange eziqhelekileyo, kwaye ziququzelela ukuhanjiswa kweekhemikhali ezahlukeneyo kunye neegesi ngexesha lenkqubo yokuvelisa.
Izibonelelo zokuvelisa amandla zixhomekeke kwiiflange eziqhelekileyo ukudibanisa iinkqubo zemibhobho kwi-steam, igesi yendalo kunye nosetyenziso lwamanzi. Iiflange zibalulekile ekugcineni imfezeko yezi nkqubo kunye nokuqinisekisa ukuveliswa nokuhanjiswa kwamandla ngokufanelekileyo. Kwiindawo zokucocwa kwamanzi, iiflange eziqhelekileyo zisetyenziselwa ukudibanisa iipayipi kunye neevalve kwiinkqubo zokucocwa kwamanzi kunye namanzi amdaka, ukunceda ukuphucula ukusebenza ngokubanzi kunye nokuthembeka kweziseko zophuhliso.
Ukukhethwa kwezinto eziphathekayo zeflange esemgangathweni kubalulekile ekusebenzeni kwayo kunye nobomi benkonzo. Izinto eziqhelekileyo ezisetyenziselwa ukwenza iiflange ziquka i-carbon steel, insimbi engenasici, insimbi ye-alloy, kunye neentsimbi ezingezona i-ferrous ezifana nobhedu kunye ne-aluminium. Ukukhethwa kwezinto eziphathekayo kuxhomekeke kwizinto ezifana neemeko zokusebenza, iimpawu zolwelo kunye nokuqwalaselwa kokusingqongileyo.
Iiflange ezisemgangathweni zenzelwe ukumelana noxinzelelo olubanzi kunye namaqondo obushushu, kunye nemilinganiselo yoxinzelelo ukusuka kwi-150 ukuya kwi-2500 yeepounds nge-intshi yesikwere (PSI). Oku kuqinisekisa ukuba zingasetyenziswa kwiintlobo ezahlukeneyo zezicelo ukusuka kwiinkqubo zoxinzelelo oluphantsi ukuya kwiindawo ezinoxinzelelo oluphezulu kunye nobushushu obuphezulu.
Isishwankathelo, ukubunjwa kunye nobubanzi bokusetyenziswa kweeflange eziqhelekileyo zibalulekile ekusebenzeni kunye nokuthembeka kweenkqubo zombhobho kumashishini ahlukeneyo. Ukuguquguquka kwazo, ukuqina kunye nokukwazi ukumelana neemeko zokusebenza ezinzima kuzenza zibe yinxalenye ebalulekileyo yendibano yothungelwano lwemibhobho. Njengoko ishishini liqhubeka nokuphuhla, imfuno yeeflange ezisemgangathweni iya kuqhubeka ikhona, ngaloo ndlela ikhuthaza ukuqhubela phambili kwenkqubo yayo yokwenza kunye nokwandisa uluhlu lwezicelo.
