I-Pipe Flange System
I-piping flange isho i-flange esetshenziselwa ukufaka amapayipi lapho kufakwa khona amapayipi, futhi ibhekisela ekungeneni nasekuphumeni kwezinto zokusebenza lapho kusetshenziswa okokusebenza. Kunezimbobo kuma-flange, futhi amabhawodi enza ama-flange amabili axhumeke ngokuqinile. Ama-flanges avaliwe ngama-gaskets. I-flange ihlukaniswe yaba uxhumano olunentambo (uxhumano olunezintambo) i-flange, i-welding flange kanye ne-clamp flange. Ama-flange asetshenziswa ngamabili, ama-wire flange angasetshenziswa kumapayipi anengcindezi ephansi, nama-flange ashiselwe ukucindezela okungaphezu kwamakhilogremu amane. I-gasket yengezwa phakathi kwama-flange amabili bese iqiniswa ngamabhawodi. Ubukhulu bama-flange anezingcindezi ezihlukene buhlukile, futhi amabhawodi abawasebenzisayo nawo ahlukile. Lapho amaphampu amanzi nama-valve exhunywe kumapayipi, izingxenye zalezi zinsiza kanye nezinto zokusebenza nazo zenziwa zibe yizimo ze-flange ezihambisanayo, ezibuye zibizwe ngokuthi ukuxhunywa kwe-flange. Zonke izingxenye zokuxhuma ezixhunywe ngama-bolts emaphethelweni ezindiza ezimbili futhi zivaliwe ngesikhathi esifanayo zivame ukubizwa ngokuthi "ama-flange", njengokuxhunywa kwamapayipi okungenisa umoya. Lolu hlobo lwezingxenye lungabizwa ngokuthi "izingxenye ze-flange". Kodwa-ke, lokhu kuxhumana kuyingxenye kuphela yemishini, njengokuxhumana phakathi kwe-flange nepompo yamanzi, akulungile ukubiza iphampu yamanzi "izingxenye ze-flange". Amancane, njengama-valve, angabizwa ngokuthi "izingxenye ze-flange".
1. Ngokwezimboni zemboni yamakhemikhali (HG) amazinga embonini: i-integral flange (IF), i-flange enentambo (Th), i-plate flat welding flange (PL), i-neck butt welding flange (WN), i-neck flat welding flange (SO), isokhethi welding flange (SW), butt welding ring loose flange (PJ/SE), flat welding ring loose flange (PJ/RJ), lining flange cover (BL(S)), Flange cover (BL).
2. Ngokwezinga lemboni ye-petrochemical (SH): i-threaded flange (PT), i-butt welding flange (WN), i-flange welding flange (SO), i-socket welding flange (SW), i-flange evulekile (LJ) , ikhava ye-Flange (ayibonisiwe ).
3. Ngokusho kwezindinganiso zemboni yemishini (JB): i-flange ebalulekile, i-butt welding flange, ipuleti eliyisicaba le-welding, ipuleti lendandatho yokushisela izinqe elixegayo, ipuleti lendandatho yokushisela eliyisicaba elixegayo, ipuleti eliyindandatho eline-flange elixegayo, ikhava ye-flange.
4. Ngokwezindinganiso zikazwelonke (GB): ama-flange abalulekile, ama-flange anentambo, ama-flange wokushisela izinqe, ama-flange okushisela entamo, ama-flange we-neck socket welding, ama-flange we-butt welding entanyeni ama-flange axekethile, ama-plate flat flanges Ama-flange wokushisela, ipuleti lendandatho yokushisela izinqe , ipuleti lendandatho yokushisela eliyisicaba elixegayo, ipuleti eliyindandatho eline-flanged elixegayo, ama-flange izembozo.
I-WCB (i-carbon steel), i-LCB (izinga lokushisa eliphansi le-carbon steel), LC3 (3.5% nickel steel), WC5 (1.25% chromium 0.5% molybdenum steel), WC9 (2.25% chromium), C5 (5% chromium 0.5% molybdenum), I-C12 (9% chromium ne-1% molybdenum), i-CA6NM (4 (12% chromium steel), CA15(4) (12% chromium), CF8M (316 stainless steel), CF8C (347 stainless steel), CF8 (304 stainless steel), CF3 (304L) Stainless steel), CF3M (316L stainless insimbi), i-CN7M (insimbi ye-alloy), i-M35-1 (Monel), i-N7M (Haast I-Nickel Alloy B), CW6M (Hasta Nickel Alloy C), CY40 (Inconel) Linda.
Inqubo yokukhiqiza ihlukaniswe kakhulu ngezinhlobo ezine: ukubumba, ukuphonsa, ukusika nokugingqa.
(1) I-flange ye-Cast kanye ne-flange ehlanganisiwe
I-flange ye-cast inesimo esinembile nobukhulu, umthamo omncane wokucubungula kanye nezindleko eziphansi, kodwa ineziphambeko zokuphonsa (ama-pores, ama-cracks, inclusions); isakhiwo sangaphakathi sokuphonsa simpofu ekuhleleni (uma kuyingxenye yokusika, ukugeleza kubi kakhulu);
Ama-flange akhiwe ngokuvamile anokuqukethwe kwekhabhoni ephansi kunama-cast flange futhi akulula ukugqwala. Ama-Forging ayahlelwa kalula, anesakhiwo esiminyene, futhi anezakhiwo ezingcono zemishini kunama-cast flange;
Inqubo yokubumba engalungile izophinda ibangele izinhlamvu zekristalu ezinkulu noma ezingalingani, ukuqhekeka okuqinile, kanye nezindleko zokubumba eziphakeme kunama-cast flange.
Ama-Forgings angakwazi ukumelana namandla aphezulu okushefa namandla aqinile kunokubunjwa.
Inzuzo ye-castings ukuthi ingakwazi ukukhiqiza izimo eziyinkimbinkimbi nezindleko eziphansi;
Inzuzo ye-forgings ukuthi isakhiwo sangaphakathi sifana, futhi azikho iziphambeko eziyingozi ezifana nama-pores kanye nokufakwa ekubunjweni;
Kusukela kunqubo yokukhiqiza, umehluko phakathi kwe-cast flange ne-forged flange uhlukile. Isibonelo, i-centrifugal flange iwuhlobo lwe-cast flange.
Ama-centrifugal flange ayingxenye yendlela yokusakaza enembile ukukhiqiza ama-flange. Uma kuqhathaniswa nokusakazwa kwesihlabathi okujwayelekile, ukwakheka kwalolu hlobo lokulingisa kuhle kakhulu, futhi ikhwalithi ithuthukiswa kakhulu. Ayithambekele ezinkingeni ezinjengokwakheka okuxekethile, izimbotshana, kanye ne-trachoma.
Okokuqala, sidinga ukuqonda ukuthi i-centrifugal flange ikhiqizwa kanjani, indlela yenqubo kanye nomkhiqizo we-centrifugal casting ukwenza i-flange ye-welding flat, ebonakala ngokuthi umkhiqizo ucutshungulwa ngezinyathelo ezilandelayo zenqubo:
① Faka insimbi eluhlaza ekhethiwe esithandweni somlilo esiphakathi nendawo ukuze incibilike, ukuze izinga lokushisa lensimbi encibilikisiwe lifinyelele ku-1600-1700℃;
② Shisisa isikhunta sensimbi sibe ngu-800-900℃ ukuze ulondoloze izinga lokushisa elingaguquki;
③ Qala i-centrifuge, bese uthela insimbi encibilikisiwe esinyathelweni ① esikhunjini sensimbi ngemva kokushisa kwangaphambili esinyathelweni ②;
④ Ukusakaza kupholiswe ngokwemvelo ku-800-900℃ futhi kugcinwe imizuzu engu-1-10;
⑤ Pholisa ngamanzi uze ufike eduze kwezinga lokushisa elivamile, susa futhi ukhiphe ukusakaza.
