Chiyambi cha mapaipi achitsulo chapamwamba cha kaboni ndi zitsulo zomangira zopangidwa ndi alloy zitsulo zopanda msoko za mapaipi a boiler okhala ndi mphamvu yamphamvu komanso pamwamba pa nthunzi

GB/T5310Mapaipi achitsulo chosasunthika ndi zinthu zapamwamba kwambiri zomwe zimapangidwa kuti zigwiritsidwe ntchito pa mapaipi a boiler okhala ndi mphamvu yamagetsi komanso pamwamba pa nthunzi. Amapangidwa ndi chitsulo chosungunuka cha kaboni komanso zitsulo zosungunuka kuti zitsimikizire kuti zimagwira ntchito bwino komanso kudalirika m'malo otentha komanso opanikizika kwambiri. Chitoliro chachitsulo chosasunthika ichi chimagwiritsidwa ntchito kwambiri popanga mapaipi a boiler ndi zosinthira kutentha, zomwe zimapereka chitsimikizo cholimba cha kupanga mafakitale.

Magiredi akuluakulu

GB/T5310Mapaipi achitsulo osasinthika amapangidwa makamaka ndi Cr-Mo alloy ndi Mn alloy, ndipo mitundu yayikulu ikuphatikizapo20G, 20Mg, 20MoG, 12CrMoG, ndi zina zotero. Zipangizozi zili ndi mphamvu yabwino kwambiri kutentha kwambiri komanso kukana okosijeni, ndipo zitha kugwiritsidwa ntchito kwa nthawi yayitali m'malo ovuta ogwirira ntchito popanda kulephera. Pakati pa izi:

20GChitsulo chapamwamba kwambiri cha kaboni chokhala ndi pulasitiki wabwino komanso kulimba, chomwe chimagwiritsidwa ntchito kwambiri m'mapaipi a boiler apakati komanso otsika mphamvu.
20Mg: Kuonjezera manganese ku 20G kumawonjezera mphamvu ndi kuuma kwa chinthucho, choyenera mapaipi a boiler apakati komanso amphamvu kwambiri.
20MoG: Molybdenum imawonjezeredwa ku 20G, zomwe zimapangitsa kuti kutentha kusamayende bwino komanso kukana kukwera, ndipo ndi yoyenera mapaipi a boiler okhala ndi mphamvu yamphamvu.
12CrMoG: Chitsulo chopangidwa ndi alloy chokhala ndi chromium ndi molybdenum, chokhala ndi kukana kwa okosijeni kutentha kwambiri komanso mphamvu yotentha kwambiri, choyenera mapaipi a boiler okhala ndi mphamvu yapamwamba kwambiri.
Magiredi achitsulo opangidwa ndi aloyi

Magawo achitsulo opangidwa ndi alloy a mapaipi achitsulo osapindika a GB/T5310 amakhalanso ndi 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, ndi zina zotero. Magawo awa a mapaipi achitsulo ali ndi mawonekedwe osiyanasiyana amakina ndi mitundu yogwiritsidwa ntchito malinga ndi kapangidwe ka mankhwala osiyanasiyana komanso njira zochizira kutentha:

15MoG ndi 20MoG: Kuwonjezera kuchuluka koyenera kwa molybdenum kumawonjezera kwambiri mphamvu yotentha komanso kukana dzimbiri kwa chitoliro chachitsulo.
12CrMoG ndi15CrMoG: Kuonjezera chromium ndi molybdenum kumawonjezera kukana kwa okosijeni ndi mphamvu ya kutentha kwambiri kwa chitoliro chachitsulo, ndipo ndikoyenera malo okhala ndi kutentha kwakukulu ndi kupsinjika.
12Cr2MoG ndi 12CrMoVG: Kapangidwe ka alloy kamakonzedwanso bwino, ndi mphamvu yotentha kwambiri komanso kukana okosijeni, ndipo imagwira ntchito bwino kwambiri m'malo ovuta kwambiri.
Mapulogalamu
Mapaipi achitsulo osasinthika a GB/T5310 amagwiritsidwa ntchito kwambiri m'mapaipi a boiler ndi zosinthira kutentha, makamaka m'zida zotenthetsera kwambiri komanso zopanikizika kwambiri monga ma boiler a siteshoni yamagetsi, ma boiler a mafakitale, ndi ma boiler otenthetsera zinyalala. Mapaipi achitsulo osasinthika awa amatha kupirira kupsinjika kwakukulu komanso kutentha, kuonetsetsa kuti ma boiler ndi zosinthira kutentha zikugwira ntchito bwino komanso kukhala ndi moyo wautali. Kuphatikiza apo, mapaipi achitsulo awa amagwiritsidwanso ntchito m'zida zosinthira kutentha mumakampani opanga petrochemical, zomwe zimakulitsa malo omwe amagwiritsidwa ntchito.
Chidule
Mapaipi achitsulo chosasunthika a GB/T5310 akhala chinthu chomwe chimakonda kwambiri pa mapaipi a boiler okhala ndi mphamvu yokwera komanso apamwamba kuposa nthunzi chifukwa cha zinthu zake zabwino komanso ntchito zake zosiyanasiyana. Kaya ndi 20G, 20Mg, 20MoG, 12CrMoG ndi zipangizo zina, kapena 15MoG, 20MoG, 12CrMoG ndi zitsulo zina zopangidwa ndi alloy, onsewa amasonyeza kukana kutentha kwambiri komanso mphamvu yotentha kwambiri, zomwe zimapereka chitsimikizo chodalirika cha magwiridwe antchito otetezeka komanso ogwira mtima a zida zamafakitale.
