Chito chowonda ndi ma flanges
Chitoliro chomwe chimadzaza ndi zolimbitsa thupi
Zopangidwa ndi zolimbitsa thupi
Mantha ndi zigawo zomwe zimagwira ntchito ngati cholumikizira pakati pa mapaipi akulu, ma valves kapena mapampi. Ubwino wokwezeka kwambiri wa kugwiritsidwa ntchito mophweka kusokonekera kotsuka ndikuyang'ana kuderali cholumikizidwa ndi ma flanges. Ma flanges nthawi zambiri amapangidwa ndi kugwiritsa ntchito njira zoweta kapena zosokoneza. Makina a flange amapanga cholumikizira pakati pa zinthu zosiyanasiyana.
Kodi Astm Astm A312 254 Sawani Swuel wopanda banga wopanda banga wopanda banga? 254 Chitoliro chosapanga chitsulo chosapanga dzimbiri ndi chosapanga chitsulo chosapanga chitsulo chosapanga chitsulo chosanjikiza chokhala ndi zinthu zazitali. Ma flanges osilira 254 nthawi zambiri amagwiritsidwa ntchito kulumikiza mapaipi, mavavu kapena zida zina, ndipo amatha kumezedwa, opukutidwa kapena oponya ma pichelines. Alloy F44 imakhudza kuvuta kukhazikika ku chloride kupsinjika kuphwanya, kukhudza ndi crevice kuturuka. 254 Chitoliro cha matope ndi chimbudzi cha kuwuzidwa mwachindunji cha chotchinga pa mapaipi pa mapaipi, omwe ndi abwino kugwirizanitsa komanso kuyendetsa bwino kwambiri, kupita patsogolo. Kuchepetsa ntchito yotsatsa pa tsamba komanso kuyika kwa tsamba la patsamba, sungani nthawi yokhazikitsa ndi ndalama zogwirira ntchito, ndikusintha kuyika, mtundu, ndikupita patsogolo pa ntchitoyi.
904l chitoliro chotsutsana ndi kupindika ndi kupindika254 Chipatuli chosapanga dzimbiri Ndi ma flanges omwe amaphatikizidwa ndi mbali imodzi kapena yonseyo ku zomwe zafotokozedwa mu Astm A312 Standard. Mapu a SS 254 osawoneka osawoneka bwino a nickel ndi cromium zomwe zili ndi 6% mor, omwe amadziwikanso kuti chitoliro cha 6MEM AS31 M'mapulogalamu ena, asme sa312 S3125Aipa ndi njira yotsika mtengo kwambiri ku Nickel ndi Titanium matows.
F44 PIP ili ndi zambiri za chromium, molybdenum ndi nayitrogeni, ndipo mphamvu zake zimakhala kawiri kawiri pa zosapanga dzimbiri. Ndipo chitoliro chopanda s31254 chisonoli chimapangidwa ndi chidutswa chonse cha zitsulo popanda seams pamwamba. Chitoliro chomata ndi chitoliro chachitsulo chopangidwa ndi mitsuko yachitsulo kapena stael zingwe mutatha. Mphamvu zokhala ndi chitoliro zosawoneka bwino ndizokulirapo kuposa chitoliro chowala. 254 Chitoma chomata ndi chingwe chimagwiritsidwa ntchito kwambiri pamadzi am'madzi, kupanga mafuta, brine mankhwala, kuwononga mafakitale ndi zakudya.
Chitoliro cha HT ndi othandizira ndi otumiza kunja kwa chitoliro chosasangalatsa. Imapereka chitoliro chosakhala chopanda chidwi ndi Asmm A182 Flange mogwirizana ndi Asm A312 251 Takulandilani.
