Insimbi engagqwalii-flangekuyingxenye ebalulekile yomsebenzi wokuxhuma ipayipi, izinhlobo eziningi, izinga liyinkimbinkimbi. Ngenxa yokumelana nokugqwala okuqinile nokumelana nokugqwala, idlala indima yokuxhuma epayipini. Ngakho-ke, isici esiyinhloko se-flange yensimbi engagqwali yindlela yokuxhuma kanye nendlela yokubeka uphawu, ipharamitha yethonya ingcindezi yepayipi.
Ngokuvamile, uhlelo lwe-low pressure (PN<2.5MPA) lusebenzisa i-flat welding nomaipuleti insimbi engagqwali flange ukubeka uphawuphezulu(RF) uphawu; Uhlelo lwe-Medium pressure (2.5-64MPA) lusebenzisa i-butt eshiselwe i-flange yensimbi engagqwali, i-RF noma i-concave-convex surface (FM/M) uphawu; Amasistimu okucindezela okuphezulu (10.0MPA noma ngaphezulu) ngokuvamile asebenzisa i-buttezishiselweinsimbi engagqwali flanged ladder groove (RJ) sealing. Kusistimu yensimbi engagqwali enengcindezi ephansi, ngezinye izikhathi ukuze kongiwe izindleko kanye nokunakekelwa okufanele, kuzophinde kukhethe i-flange yensimbi engagqwali exekethile noma indandatho ye-flange yensimbi engenasici.
Izindlela zokusebenzisa nokunakekela:
1. Isitoreji sesikhathi eside se-flange yensimbi engagqwali, kufanele igcinwe njalo, ngokuvamile ivuleleke ngaphandle kwendawo ekhiqizwayo kanye nendawo yokucubungula kufanele igcinwe ihlanzekile, isuse amabala, igcinwe kahle endaweni engokwemvelo enomoya owomile kanye ne-manetic, ukupakishwa okungavunyelwe noma ngaphandle. isitoreji. Ukugcina i-flange yensimbi eyomile nomoya omncane wemvelo, i-retainer esobala ihlanzekile futhi icocekile, ngokuhambisana nendlela efanele yokugcina.
2. Ngaphambi kokufaka, qiniseka ukuthi uhlola ukucaciswa ngakunye kanye nosayizi we-flange yensimbi engagqwali: kungakhathaliseki ukuthi ububanzi bepayipi buhambisana nemithetho yesicelo, susa ukushiyeka okubangelwa inqubo yokuthutha, futhi ususe amabala e-stainless steel flange, wenze kahle. ukulungiselela kusengaphambili ngaphambi kokufakwa, konke sekumi ngomumo.
3. Ngesikhathi sokufakwa, i-flange yensimbi engagqwali ingafakwa ngokushesha epayipini ngokusho kwemodi yesixhumi esibonakalayo, futhi ukufakwa kungenziwa ngokuya ngesikhundla sohlelo lokusebenza. Ngokuvamile, ingafakwa kunoma iyiphi ingxenye yepayipi, kodwa idinga ukuhambisana nokugcinwa kokusebenza kwangempela. Naka ukungena kwezinto ezibonakalayo ze-stainless steel flange kufanele kube i-disc valve longitudinal ngaphansi kosaziwayo, futhi i-stainless steel flange iwukufakwa okuvundlile kuphela. I-stainless steel flange ekufakweni kufanele inake ukuqina, ukugwema ukuvuza, ukulimaza konke ukusebenza okujwayelekile kwepayipi.
4. I-valve yesango le-flange yensimbi engagqwali, i-valve yokumisa, isicelo se-valve yokumisa, kuphela i-seal evulekile egcwele noma egcwele, ayivunyelwe ukulungisa ukugeleza okuphelele, ukuze kuvinjelwe ukuguguleka kwendawo, ukusheshisa umonakalo. I-valve yokumisa kanye ne-valve yokumisa intambo yangaphandle engenhla inemishini yokuvala ehlanekezelwe, futhi isibambo siqiniswa engxenyeni engenhla ukuze kuvinjwe ukuthi impahla ingavuzi entweni yokugcwalisa.
Indlela yokwelapha i-stainless steel flange corrosion:
1. Hlanza ngendwangu ye-emery ne-wire brush.
2. Sebenzisa ifosholo lensimbi ye-tungsten ukuze ususe izindawo ezinkulu zokugqwala.
3. Susa ama-protrusions afana ne-welding slag kanye nama-burrs ahlukahlukene ngefayela.
4. Susa ukugqwala emakhoneni nge-scraper kanye nebhulashi locingo.
5. Hlanza nge-rag ehlanzekile, noma cwilisa ku-solvent rag primer ngesikhathi.
6. Nakani enamathela ukuqina akuphumelelanga, ingagcinwa. Sebenzisa indwangu ye-emery ukuze ugcobe ingaphezulu likapende omdala, ugcobe iziphambeko zokumboza zibe umumo wezembe, futhi upende ngokuqondile ngemva kokuhlanza.
