SA213 chubu cha boiler chothamanga kwambirimndandanda ndichubu cha boiler chothamanga kwambirimndandanda. Yoyenera machubu achitsulo a ferritic ndi austenitic opanda msoko okhala ndi makulidwe ochepa a khoma la ma boiler ndi ma superheaters ndi machubu achitsulo a austenitic a ma heat exchangers.

Mapaipi otenthetsera pamwamba omwe amagwiritsidwa ntchito mu ma boiler opanikizika pang'ono ndi apakati (kupanikizika kogwira ntchito nthawi zambiri sikupitirira 5.88Mpa, kutentha kogwira ntchito kuli pansi pa 450℃); amagwiritsidwa ntchito mu ma boiler opanikizika kwambiri (kupanikizika kogwira ntchito nthawi zambiri kumakhala pamwamba pa 9.8Mpa, kutentha kogwira ntchito kuli pakati pa 450℃ ~ 650℃) ) machubu otenthetsera pamwamba, ma superheater, ma reheater, machubu amakampani a petrochemical, ndi zina zotero.

ASME SA213 T12Chitoliro chachitsulo cha alloy, chomwe chikutsogolera pa mapaipi achitsulo osasemphana aku America, chimagwiritsidwa ntchito kwambiri mu mafuta, makampani opanga mankhwala, magetsi ndi mafakitale ena. Chitoliro chachitsulo chamtunduwu chimapangidwa ndi chitsulo chapamwamba kwambiri. Pambuyo pochikonza mosamala m'njira zosiyanasiyana, chimakhala ndi mphamvu zambiri komanso kukana dzimbiri kwambiri. Chimatha kukwaniritsa zofunikira zogwiritsidwa ntchito m'malo osiyanasiyana ovuta.

Njira yake yopangira ndi yovuta komanso yokongola, kuphatikizapo kusungunula, kuzunguliza, kuboola, kukoka kozizira, kutentha ndi maulalo ena. Pa nthawi yopangira, chitoliro chachitsulo chimayesedwa kangapo kuti chitsimikizire kuti chili bwino komanso chodalirika. Palinso kusanthula kwa mankhwala osiyanasiyana, kusanthula kwa metallographic ndi mayeso ena kuti zitsimikizire kuti kapangidwe kake, kapangidwe ka bungwe, magwiridwe antchito ndi zizindikiro zina zikukwaniritsa zofunikira.

Makhalidwe aASME SA213 T12Chitoliro chachitsulo cha alloy ndi ichi:
1. Mphamvu yayikulu: Ili ndi mphamvu yayikulu yokoka komanso yokwera mtengo, ndipo imatha kupirira katundu waukulu ndi kugundana.
2. Kukana dzimbiri kwambiri: Kukana dzimbiri kwambiri m'malo osiyanasiyana ovuta, monga ma acid, ma alkali, mchere ndi mankhwala ena komanso m'malo ovuta kwambiri monga kutentha kwambiri ndi kutentha kochepa.
3. Kugwira bwino ntchito yolumikiza: Yopangidwa ndi chitsulo chapamwamba kwambiri, siimakhala ndi ming'alu, ma pores ndi mavuto ena panthawi yolumikiza, zomwe zimapangitsa kuti ikhale yabwino komanso yodalirika.
4. Ntchito zosiyanasiyana: Zimagwiritsidwa ntchito kwambiri m'mafakitale a mafuta, mankhwala, magetsi ndi mafakitale ena, monga mapaipi amafuta ndi gasi, ma boiler, ma reactor ndi zida zina.
