Ama-flange ensimbi engenasici asetshenziswa kabanzi kuzo zonke izigaba zokuphila ngenxa yokubukeka kwawo okuhle, izinga lokushisa eliphezulu nokumelana nokucindezela okukhulu, ukumelana nokugqwala nezinye izici. Kodwa-ke, abantu abaningi basenezinkinga eziningi ekusetshenzisweni kwama-flange ensimbi engagqwali. Namuhla sizokhuluma ngendlela yokuxazulula izinkinga ezenzeka ohlelweni lokungacubunguli ama-flange ensimbi engagqwali.
Ukucutshungulwa kweinsimbi engagqwali flangeidinga ukwazi nokunaka ezinye izinkinga:
1. Isici esihlangene se-Weld: isici sokushisela se-flange yensimbi engagqwali sibi kakhulu. Uma i-polish mechanical polishing isetshenziselwa ukwenza khona, izimpawu zokugaya zizobangela indawo engalingani futhi ithinte ukubukeka;
2. Ukupholisha okungalingani kanye nokudlula: ngemuva kokupholisha ngesandla nokupholisha, kunzima ukufeza umphumela wokwelashwa ofanayo nofanayo wezinto zokusebenza ezinendawo enkulu, futhi awukwazi ukuthola indawo efanelekile yomfaniswano. Ukuxhumana kwe-flange enentamo noma i-flange joint ibhekisela ekuxhumekeni okukhiphekayo kwe-flange, i-gasket ne-bolt njengeqembu lesakhiwo esihlanganisiwe sokuvala.
I-flange yepayipi isho i-flange esetshenziselwa ukubhobhoza emshinini wepayipi, kanye nama-flange okungena nokuphuma kwezinto lapho kusetshenziswa impahla. Kukhona izimbobo kui-flange, namabhawodi enza ama-flange amabili axhumeke ngokuqinile. I-butt-welding flange iwuhlobo lokufakwa kwamapayipi, okubhekiselwa ku-flange enentamo nenguquko yepayipi eliyindilinga futhi exhunywe ngokushisela izinqe zepayipi. Akulula ukukhubaza, kuvalwe kahle futhi kusetshenziswe kabanzi. Ifanele amapayipi anokushintshashintsha okukhulu kwengcindezi noma izinga lokushisa noma amapayipi anokushisa okuphezulu, ukucindezela okukhulu kanye nezinga lokushisa eliphansi. Inzuzo ukuthi intengo ishibhile, futhi ukucindezela okuzisholo akudluli i-2.5MPa;
Iphinde isetshenziswe kumapayipi athutha imidiya ebizayo, evuthayo kanye neziqhumane, enengcindezi elinganiselwa ku-PN16MPa. Kukhona futhi nebubi bayo, njengezindleko zamahora okusebenza nezinto ezisizayo;
3. Kunzima ukususa imihuzuko: ukugqwala nokudlula konke, ukugqwala kwamakhemikhali noma ukugqwala kwe-electrochemical kuzokwenzeka futhi ukugqwala kuzokwenzeka lapho kukhona izinto ezibolayo (izinto ezinqumayo), kanye ne-carbon steel, i-spatter nokunye ukungcola okunamathela phezu kwensimbi engagqwali. ngenxa yokuklwebheka kanye ne-welding spatter ayikwazi ukususwa;
Ngakho indlela yokuxazulula inkinga yeinsimbi engagqwali flangeiyacubungula?
1. Khetha ukungasho lutho, bese ufaka inqubo elandelayo. Ama-workpieces ahlukene ekucutshungulweni kwe-flange yensimbi engenasici afaka inqubo ehambisanayo ngokuya ngezidingo zokucubungula;
2. Lapho ugoba, ithuluzi kanye nomsele osetshenziselwa ukugoba kuzonqunywa ngokuhambisana nobukhulu bomdwebo kanye nobukhulu bepayipi lensimbi engenamthungo engu-304. Isihluthulelo sokukhethwa kwesikhunta esiphezulu ukugwema ukuguqulwa okubangelwa ukungqubuzana phakathi kwe-flange nethuluzi (incazelo: ingxenye ebalulekile yesifaniso) (amamodeli ahlukene esikhunta esiphezulu angasetshenziswa kumkhiqizo ofanayo). Ukukhethwa kwesikhunta esiphansi kunqunywa ngokusho kobukhulu bepuleti. Lapho uxhuma iphampu ne-valve yomkhiqizi we-flange nepayipi, izingxenye zalezi zinsiza nazo zenziwa zibe yizimo ezihambisanayo ze-flange, ezaziwa nangokuthi uxhumano lwe-flange.
3. Ukuze ushise ngokuqinile, shaya i-bump ku-workpiece ukuze i-welded, engenza ukuthintana kwe-bump ne-flat plate ngokulinganayo ngaphambi kwamandla-on-welding ukuqinisekisa ukuvumelana kokushisisa endaweni ngayinye, futhi unqume indawo yokushisela. , edinga ukushiselwa. Lungisa isikhathi sokucindezela kwangaphambili, isikhathi sokubamba ingcindezi, isikhathi sokunakekela, nesikhathi sokuphumula ukuze uqinisekise ukuthi ucezu lokusebenza lungashicilelwa ngokuqinile.
