A \ SA387 GR 11 Ibanga 2 Umthamo Wengcindezi Ibanga lensimbi yenkonzo ephezulu yokushisa, i-ASTM A387 \ SME SA387 Ibanga 11 Ibanga le-9 lisebenzisa izimboni ezingamafutha, ikakhulukazi ezimbonini lapho kugcinwa khona amazinga okushisa aphezulu.

Izinga eliphakeme le-chromium liphinde linikeze ukubhujiswa okuhle kakhulu kanye nokuphikiswa yi-oxidation, okumele kusetshenziswe kuzinhlelo zegesi ezimuncu. A \ SA387 gr 12 Ibanga 2 ASTM A387 \ ASME SA387 Ibanga le-12 lenzelwe izinhlelo zokusebenza eziphezulu zokushisa futhi i-chromium molybdenum carbon albon alloy alboy alloy lensimbi kanye namabili wezimboni. Ngenxa yokwengeza i-chromium, okuqukethwe kunesimo sokugqwala esihle kakhulu kanye nokumelana ne-oxidation, okwenza kube kuhle ngezinhlelo zokusebenza zensiza emuncu embonini kawoyela negesi.

Enye yezinzuzo ze-A387 Alloy Steel Plate ukusebenza okuphezulu, uhlaka lwayo oluqinile kuvumela i-ASME SA 387 I-11 ipuleti yensimbi ye-alloy ukuhlinzeka ukusebenza okuphezulu ezindaweni eziphakeme zomsebenzi. Bathola ukusetshenziswa okubalulekile kwezicelo eziphakeme zokucindezela ezifana nama-valves nama-boilers ngoba abakwenzi ngaphansi kwengcindezi enkulu. Izindawo zabo eziqinile ngeke ziqhekeze noma zidume ngokushaqeka okungazelelwe noma ukuguquguquka. Ngaphezu kwalokho, zingacutshungulwa ngokuqhubekayo ngaphandle kokulahlekelwa yinani.

Ukwenza lula ukuhlonza, kubulawe i-Alloy Steel SA 387 GR 91 amapuleti angamakwe ngenhlokodolobha "K". Ibanga 91 likushisa kuphathwe ngokusho kwalolu mbala. I-Alloy Heat Treatment Proceties yanoma yiliphi ifomu, kufaka phakathi ukwakhiwa kwe-ASTM A387 Ibanga le-91 CL1 le-Plate ye-A31 CL1 yezinto ezisezingeni eliphakeme ezikwazi ukumelana namazinga okushisa aphezulu. I-SA 387 GR 91 CL2 SHEEL inamandla aphezulu wemishini.

Enye yezinzuzo zepuleti yensimbi ye-A387 ye-A387 iyinhlangano yayo enhle, i-ASTM yethu ipuleti yensimbi engu-387 ye-Alloy 91 ine-concticity enhle, inokwakheka okuhle futhi inganqunywa ibe yibunjwa abaningi. Inqubo eyejwayelekile nenogunda inika ishidi lensimbi le-alloy libe ngumzimba oqinile kodwa oqinile ngenxa yokuvuselela kabusha nokupholisa. Ekugcineni, bathola ukuzungeza okuhle kakhulu futhi kulula ukuthengisa ukwakha ama-supERScturetures.

Izakhiwo eziningi ezinhle kakhulu ezitholakala kumkhiqizo ofanayo ngenxa yokukhiqizwa kweshidi okungcono. Lawa ngamandla aphezulu ashubile, ukunemba okuhle okuyisisekelo, ukuqeda okungaphezulu, ukuguquguquka nokuqina, ukubekezelela imithwalo esindayo, ukwakhiwa okunamandla nokuphikiswa kokugqwala kanye nokuphikiswa kokugqwala. Ukumelana nokugqwala, ukuqhekeka kokugqwala kwengcindezelo, ukuqhekeka kwe-crevice corrosion, i-oxidation \

I-ASTM \ ASME A387 \ SA387 Alloy Steel Gr. I-5 CL 1 \ 2 iyipuleti yensimbi ye-chrome molybdenum alloy esetshenziswe ngokuyinhloko kuma-boilers we-welded kanye nemikhumbi yengcindezi eyenzelwe i-High Temperity Service. Okuqukethwe kwe-CR kwakungu-5.00%, futhi okuqukethwe kwe-MO kwakungu-0.5%.

Singabaninimasheya ku-ASME SA 387 Ibanga 9 le-Alloy Store Plate Plate, elinamandla amakhulu futhi avune amandla ukuze asetshenziswe emazingeni okushisa aphezulu. Inhlanganisela ye-chromium-molybdenum inika la mapuleti ukumelana nokuphikiswa kwamapuleti futhi athuthukise amandla ashubile emazingeni okushisa aphakeme.

A \ SA387 gr 5Class 2 Iplate yensimbi ye-chrome-molybdenum ephezulu yenzelwe ngokukhethekile ukusetshenziswa emikhunjini eshisayo ye-carbon iron tressress emazingeni okushisa aphezulu. I-molybdenum eyengeziwe inika impahla ephakeme yokushisa amandla ashubile, kanti i-chromium ihlinzeka ngokumelana okungcono kokugqwala.

Enye yezinzuzo zepuleti yensimbi ye-A387 ye-a387 iwumzimba olwa nokugqwala, ipuleti yensimbi ye-chrome-molybdenum inezindawo zokulwa nokugqwala, ezinganciphisa ifilimu lokugqwala ebusweni bayo, ngakho-ke ukugcwala kwe-nip ku-bud. Amashidi ensimbi we-Gost 15KH5m asetshenziswa kakhulu embonini yamakhemikhali ngenxa yokumelana nawo ngezinhlobo ezahlukahlukene zokugqwala okufana nokugqwala okumanzi, ukugqwala kwe-crevice, ukugcwala kwe-hydrogen ukuqhekeka, okuholela ekuhambeni komkhiqizo okuhle.

A \ SA387 GR 22 Ibanga 2 Sinikeza amapuleti ama-2 sa387 22 Banga-2 Banga 2 Amapuleti kubakhiqizi emafutheni, egesi kanye nezimboni ze-petrochemical. Lezi zimboni zidinga izingcindezi ze-verel grade steples ezenza kahle emazingeni okushisa aphezulu, futhi izinto zethu zokwakha zisebenzela leyo nhloso kahle. I-2 SA387 I-Class 22 Ishidi le-Class 2 linokuphikiswa okuhle nokuphikiswa yi-oxidation futhi kuyisinqumo esihle.

A \ SA387 gr 91class 2 lapho kuvunywa khona ukumelana kwamazinga okushisa kanye nokuphikiswa okuhle kokugqwala, isigaba 2 Carbon Alloy Insimbi yensimbi ethile okufanele icatshangelwe. Yinsimbi yebanga lengcindezi yebanga elisetshenziswa kakhulu abakhiqizi abahlinzeka ngemboni kawoyela negesi.

I-A \ SA387 Ibanga 91 nayo inketho yokusetshenziswa ezindaweni ezihlonishwayo ngenxa yokumelana kahle nokuqina kwezinto ezibonakalayo. Okuqukethwe kunama-weldiality amahle nokuphikiswa ukushisa, okwenza kube yinsimbi eguquguqukayo engasetshenziswa ezinhlelweni ezahlukahlukene.

Iplate yensimbi ye-alloy ingcono kunepuleti yensimbi yekhabhoni. Isizathu? I-ASTM ishidi lensimbi engu-387 ye-alloy le-127 liyawaphendula ngokwengeziwe ekwakhekeni kwezindlela zokushisa nezinqubo ezisebenza ngemishini. Ziyakhiwa i-Chromium, i-molybdenum, i-manganese, i-silicon, nokuningi, zibenze zibe namandla, zibe nzima, zivimbela ukushisa, futhi zibe ne-weldable.

Amashidi ensimbi aqinile ahlala isikhathi eside ngoba ajwayelekile futhi ancishiswe ukuthola indawo enzima. Ukuvuselelwa okugcwele ubuso ngokunciphisa ukucindezela kwangaphakathi, okuholele ekwakhekeni okufanayo kwe-ASME SA387 IBANDLA 22 IBHAYIBHELI LEBHODI. Ngakho-ke, lezi zindlela zokwelapha zinikeza amabhodi asindayo asebenza akwazi ukumelana nokushaywa okunamandla.
