Isingeniso:
Isembozo se-Flange, esaziwa nangokuthi amapuleti ayimpumputhe noma ama-flanges ayimpumputhe, adlala indima enkulu kuhlelo olujwayelekile lukazwelonke lwe-flange. Lawa mapuleti aqinile, afana nezembozo zensimbi, izakhi ezibalulekile ezisetshenziselwa ukuvimba ukuvuleka kwamapayipi futhi zivimbele ukuchichima. Ngaphezu kwalokho, ama-flanges ayimpumputhe athola izinhlelo zokusebenza ezimweni ezahlukahlukene, njengamapayipi egatsha anikeze amanzi nezingxenye zesikhashana ngesikhathi sokuhlolwa kwengcindezi. Kulesi siqondisi esiphelele, sizokwelulwa ngamazinga okukhiqiza ama-flanges amangalisayo, sihlola amazinga adumile afana ne-Asi, Din, JIS, ama-BS, nokuningi. Ngaphezu kwalokho, sizosikhanyisela amamaki ensimbi aqashwe ekukhiqizeni ama-flanges ayimpumputhe, aqinisekise ukuqonda kwakho kwale nto ebucayi.
Isigaba 1: Ukuqonda i-Flange Imboza nemisebenzi yazo
Isembozo se-Flange, esaziwa kakhulu njengamapuleti angaboni noma ama-flanges ayimpumputhe, yizingxenye ezihlanganayo zezinhlelo zamapayipi. Injongo yabo ukuvimba ukuvuleka kwamapayipi ngempumelelo futhi kuvikele okuqukethwe ekuchitheni. Kwenziwe ngezinto eziqinile, izembozo ze-flange zizungezwe izimbobo ze-bolt zokunamathiselwa okuphephile. Ifana nesembozo sensimbi esiqinile, ingatholakala emiklamo ehlukahlukene, efana nefulethi, ephakanyisiwe, i-concave kanye ne-convex, nolimi kanye ne-groove. Ngokungafani ne-butt welding flanges, ama-flange amangalisayo awaswele intamo. Lezi zingxenye zivame ukusetshenziswa ekugcineni kwamapayipi egatsha anikela ngamanzi, ukuqinisekisa ukuthi akukho ukuvuza okungalindelekile noma ukuphazamiseka.
Isigaba 2: Ukuhlola amazinga okukhiqiza ampumputhe
Ama-Flanges ayimpumputhe anamathela kumazinga athile okukhiqiza ukuze aqinisekise ikhwalithi, ukuvumelana, kanye nokuhambisana. Izindinganiso ezidumile embonini zifaka i-ANSI B16.5, DIN2576, JISB2220, KS B1503, I-ISO7005-1: 19920, 1992, ND209-1: 19123.4.1 ~ 9123.4-2000, JB / T86.1 ~ 86.2-1994. Izinga ngalinye libonisa izici ezahlukahlukene zokuvutha ama-flanges, njengobukhulu, izidingo ezibonakalayo, izilinganiso zengcindezelo nezinqubo zokuhlola. Kubalulekile ukubonana nezinga elithile elifanele kwiphrojekthi yakho ukuqinisekisa ukusebenza kahle kwe-Flange Flielight kanye nokuhambisana nohlelo lwakho lwepayipi.
Isigaba 3: Amamaki ensimbi angembukeli asetshenziswa ekukhiqizeni okumpumputhe kwe-Flange
Ukukhethwa kwamabanga ensimbi kudlala indima ebalulekile ekukhiqizeni ama-flanges ayimpumputhe, njengoba kuthinta ngokuqondile ukuqina kwawo, amandla, kanye nokumelana nokugqwala. Amabanga ahlukahlukene ensimbi aqashwa ekukhiqizeni kwe-Flange empumputhe, kufaka phakathi kepha akunqunyelwe ku:
1. I-Carbon Steel: Inketho ebiza kakhulu ngamandla amahle nokumelana namazinga okushisa aphezulu. Amabanga ajwayelekile we-Carbon Insimbi esetshenzisiwe yi-ASTM A105, ASTM A350 LF2, ne-ASTM A516 Gr. 70.
2. Insimbi Engagqwali: Ilungele izinhlelo zokusebenza lapho ukumelana nokuqina kubalulekile. Amamaki ensimbi athandwayo afaka i-ASTM A182 F304 / F304L, ASTM A182 F31666 / F316L, ne-ASTM A182 F321.
3. Insimbi ye-Alloy: Lawa mamaki ensimbi athuthukisa ukumelana nokuphikiswa okuyimpumputhe kubahloli abathile, njengamazinga okushisa aphezulu noma izindawo ezihlaselayo. Amamaki ensimbi ejwayelekile asetshenziswa yi-ASTM A182 F5, ASTM A182 F9, ne-ASTM A182 F91.
Kubalulekile ukukhetha ibanga lensimbi elifanele ngokususelwa kwizidingo ezithile zephrojekthi yakho, ucubungula izinto ezifana nendawo yokusebenza, ingcindezi, izinga lokushisa kanye nokuvezwa kwamakhemikhali.
Isigaba 4: Ukuqinisekisa ama-flanges asezingeni eliphakeme futhi ahambisana namakhono
Lapho ethola ama-flanges ayimpumputhe, kubalulekile ukuze uqinisekise ukuthi ahambisana namazinga okukhiqiza afanele kanye nezitifiketi zekhwalithi. Funa abahlinzeki abadumile abanamathela ezinqubweni zokukhiqiza eziqinile, ukuqinisekisa ama-flanges abo abayizimpumputhe ahlangana noma adlule izidingo zezimboni. Ngaphezu kwalokho, cabanga abahlinzeki abahlinzeka ngezitifiketi zokuhlola ezibonakalayo (MTC) ngokulawulwa kwekhwalithi eqinile. Le mibhalo iqinisekisa ukuthi ama-flanges ayimpumputhe akwenzile ukuhlolwa okudingekayo, okuqinisekisa ukufaneleka kwawo kwephrojekthi yakho.
Isigaba 5: Isiphetho Nezincomo Zokugcina
Ama-Flanges ayimpumputhe, owaziwa nangokuthi i-Flange emboza noma amapuleti ayimpumputhe, yizakhi ezisemqoka ezinhlelweni zamapayipi. Ukukhiqizwa kwabo kunamathela kumazinga athile okuqinisekisa ukuvumelana nokuvumelana. Izindinganiso zokukhiqiza ezidumile ezinjenge-ANSI B16.5, DIN, JIS, kanye nama-BS zibonisa ubukhulu be-Flange's, izidingo ezibonakalayo, nezilinganiso zokucindezela. Ngaphezu kwalokho, amamaki ensimbi anjengensimbi yekhabhoni, insimbi engagqwali, nensimbi ye-alloy kukhethwe ngokucophelela ukuqinisekisa ukusebenza kahle nokuphila isikhathi eside. Lapho ethola ama-flanges ayimpumputhe, ngaso sonke isikhathi khetha abahlinzeki abadumile ababeka phambili ikhwalithi futhi banikeze izitifiketi ezidingekayo. Ngokuqonda amazinga okukhiqiza ama-Flanges ama-Flanges kanye namamaki ensimbi, ungazikhethela ngokuzethemba ngezinto ezilungile ezinhlelweni zakho zamapayipi, uqinisekise ukusebenza okusebenzayo nokuphephile.
