Inkqubo yePipe Flange
I-piping flange ibhekiselele kwiflange esetyenziselwa imibhobho kufakelo lombhobho, kwaye ibhekisa kwindawo yokungena kunye neeflange zokuphuma zesixhobo xa zisetyenziswa kwisixhobo.Kukho imingxunya kwiiflange, kwaye iibholithi zenza ukuba iiflange ezimbini zidityaniswe ngokuqinileyo.Iiflange zitywinwe ngee-gaskets.I-flange yohlulwe ibe yintambo edibeneyo (uxhulumaniso lwemisonto) i-flange, i-welding flange kunye ne-clamp flange.Iiflange zisetyenziswa ngababini, iiflange zocingo zingasetyenziselwa imibhobho yoxinzelelo oluphantsi, kunye neeflange ezidityanisiweyo zoxinzelelo olungaphezu kweekhilogram ezine.I-gasket yongezwa phakathi kweeflange ezimbini kwaye emva koko iqiniswe ngeebholiti.Ubunzima beeflange ezinoxinzelelo oluhlukeneyo luhluke, kwaye iibholiti abazisebenzisayo nazo zihluke.Xa iimpompo zamanzi kunye neevalvu ziqhagamshelwe kwimibhobho, iinxalenye zezi zixhobo kunye nezixhobo nazo zenziwe zibe yimilo yeflange ehambelanayo, ezikwabizwa ngokuba luqhagamshelo lweflange.Zonke iinxalenye ezidibanisayo ezidityaniswe ngamabholiti kwi-periphery yeendiza ezimbini kwaye zivaliwe ngexesha elifanayo zibizwa ngokuba yi "flanges", ezifana nokudityaniswa kwemibhobho yokungenisa umoya.Olu hlobo lwamacandelo lunokuthiwa "i-flange parts".Nangona kunjalo, olu xhulumaniso luyingxenye yezixhobo kuphela, ezifana nokudibanisa phakathi kwe-flange kunye nepompo yamanzi, akulungile ukubiza impompo yamanzi "iindawo ze-flange".Iincinci ezincinci, ezinjengeevalve, zinokubizwa ngokuba "kwiindawo zeflange".

I-WCB (i-carbon steel), i-LCB (i-low-low carbon steel), i-LC3 (3.5% yensimbi ye-nickel), i-WC5 (i-1.25% ye-chromium 0.5% yentsimbi ye-molybdenum), i-WC9 (2.25% chromium), i-C5 (i-5% ye-chromium 0.5% molybdenum), C12 (9% chromium kunye 1% molybdenum), CA6NM (4 (12% chromium steel), CA15 (4) (12% chromium), CF8M (316 stainless steel), CF8C (347 steel stainless), CF8 (304 stainless steel ), i-CF3 (304L) insimbi engenasici), i-CF3M (316L insimbi engenasici), i-CN7M (intsimbi ye-alloy), i-M35-1 (i-Monel), i-N7M (i-Haast Nickel Alloy B), i-CW6M (i-Hasta Nickel Alloy C), i-CY40 (i-Inconel) Yima.
Inkqubo yemveliso yahlulwe kakhulu kwiindidi ezine: ukubumba, ukuphosa, ukusika kunye nokuqengqeleka.
(1) Phosa iflenge kunye neflange ebunjiweyo
I-flange ephosiweyo inemilo echanekileyo kunye nobukhulu, umthamo omncinci wokucubungula kunye neendleko eziphantsi, kodwa ineziphene zokuphosa (i-pores, i-cracks, inclusions);isakhiwo sangaphakathi sokuphosa sihluphekile kwi-streamline (ukuba inxalenye yokusika, i-streamline imbi ngakumbi);
Iiflange ezibunjiweyo zihlala zinekhabhoni ephantsi kuneeflange eziphosweyo kwaye akukho lula ukurusa.I-Forgings ilungelelanisiwe, inesakhiwo esixineneyo, kwaye ineempawu ezingcono zoomatshini kuneeflange eziphosiweyo;
Inkqubo yokubumba engafanelekanga iya kubangela ukuba iinkozo zekristale ezinkulu okanye ezingalinganiyo, ukuqhekeka kokuqina, kunye neendleko zokukhwabanisa eziphezulu kunezintlu eziphosiweyo.
I-Forgings inokumelana ne-chear ephezulu kunye ne-tensive force kune-castings.
Inzuzo yokuphosa kukuba inokuvelisa iimilo ezinzima kunye neendleko eziphantsi;
Inzuzo ye-forgings kukuba isakhiwo sangaphakathi siyafana, kwaye akukho ziphene ezinobungozi ezifana ne-pores kunye nokufakwa kwi-casting;
Ukususela kwinkqubo yokuvelisa, umahluko phakathi kweflange ephosiweyo kunye neflange eyenziwe yahlukile.Ngokomzekelo, i-centrifugal flange luhlobo oluthile lwe-flange.
Iiflange zeCentrifugal zezendlela echanekileyo yokuphosa ukuvelisa iiflange.Xa kuthelekiswa nokuphosa kwesanti eqhelekileyo, isakhiwo solu hlobo lokuphosa siphucuke kakhulu, kwaye umgangatho uphuculwe kakhulu.Ayiqhelekanga kwiingxaki ezinje ngesakhiwo esixekileyo, iipores, kunye netrakoma.
Okokuqala, kufuneka siqonde indlela i-centrifugal flange eveliswa ngayo, indlela yenkqubo kunye nemveliso ye-centrifugal casting ukwenza i-flange ye-welding flange, ebonakaliswe ukuba imveliso icutshungulwa ngokulandela la manyathelo alandelayo:
① Beka intsimbi ekrwada ekhethiweyo kwiziko lombane eliphakathi rhoqo ukuze kunyibilikiswe, ukuze ubushushu bentsimbi etyhidiweyo bufike kwi-1600-1700℃;
② Ukushisa i-mold yensimbi kwi-800-900℃ ukugcina ubushushu obuqhubekayo;
③ Qalisa i-centrifuge, kwaye ugalele intsimbi etyhidiweyo kwinqanaba ① kubumba lwentsimbi emva kokufudumeza kwangaphambili kwinqanaba ②;
④ Ukuphosa kupholiswe ngokwendalo ukuya kwi-800-900℃ kwaye igcinwe imizuzu eyi-1-10;
⑤ Pholisa ngamanzi ukuya kufutshane nobushushu obuqhelekileyo, susa kwaye ukhuphe ukuphosa.
