a. Indlela yokususa i-oxidation ichazwa kanje: FF: Insimbi ebulewe ngokuphelele equkethe izinto zokubopha i-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isb. ubuncane be-0,020% iyonke i-Al noma i-0,015% i-Al encibilikayo). b. Inani eliphezulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa okuqukethwe okungenani kwe-Al okungu-0,020% kanye nesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izinto ezibophayo ze-N ezanele. Izinto ezibophayo ze-N kufanele ziqoshwe kuDokhumenti Yokuhlola.

Ukuhlolwa Kwamanzi

Ubude bepayipi ngalinye kufanele buhlolwe ngumenzi ngengcindezi ye-hydrostatic ezokhiqiza odongeni lwepayipi ukucindezeleka okungaphansi kuka-60% wamandla amancane okukhiqiza ashiwo ekushiseni kwegumbi. Ukucindezela kuzonqunywa yi-equation elandelayo:
P=2St/D

Izinguquko Ezivumelekile Ezisindweni Nasezilinganisweni

Ubude bepayipi ngalinye kufanele bulinganiswe ngokwehlukana futhi isisindo salo akumele sihluke ngaphezu kuka-10% noma u-5.5% ngaphansi kwesisindo salo esicatshangelwayo, kubalwe kusetshenziswa ubude balo kanye nesisindo salo ngobude beyunithi ngayinye.
Ububanzi bangaphandle akufanele buhluke ngaphezu kuka-±1% kusuka kububanzi obujwayelekile bangaphandle obubekiwe
Ubukhulu bodonga nganoma yisiphi isikhathi akufanele bube ngaphezu kuka-12.5% ngaphansi kobukhulu bodonga obubekiwe

Isingeniso Somkhiqizo

Sethula uhla lwethu lwemikhiqizo yekhwalithi ephezulu yezingxenye zesakhiwo ezihlanganisiwe ezibandayo ze-EN 10219 S235JRH ezifakwe insimbi eziklanyelwe ukuhlangabezana nezidingo eziqinile zamaphrojekthi wokwakha nobunjiniyela besimanje. Izingxenye zethu zesakhiwo ezingenalutho zitholakala ngefomethi eyindilinga, eyisikwele neyingxande, okuqinisekisa ukuguquguquka kanye nokuzivumelanisa nezimo kwezinhlelo zokusebenza ezahlukahlukene.

OkwethuI-EN 10219 S235JRHIzingxenye ezingenalutho zilungele izinhlelo zokusebenza ezahlukahlukene okuhlanganisa ukwakhiwa, ingqalasizinda kanye nokukhiqiza. Kungakhathaliseki ukuthi ufuna izinto ezithembekile zephrojekthi entsha yokwakha noma udinga izingxenye zemishini yezimboni, imikhiqizo yethu esezingeni eliphezulu izokunikeza amandla nokuzinza okudingayo.

Inzuzo yomkhiqizo

Enye yezinzuzo eziyinhloko zensimbi ye-S235JRH ukushintshwa kwayo okuhle kakhulu, okwenza ifaneleke kakhulu ezinhlotsheni ezahlukene zokwakha. Izakhiwo zayo ezibandayo ziyenza ibe nobukhulu obuqondile kanye nezindawo ezibushelelezi ezingathuthukisa ubuhle besakhiwo.

Ngaphezu kwalokho, le nto inamandla amahle okubamba kanye nokuguquguquka, okunikeza ukwesekwa okudingekayo kwezicelo zokuthwala imithwalo.

Ukushoda Komkhiqizo

Nakuba i-S235JRH ifaneleka ezinhlotsheni eziningi zezakhiwo, ingase ingasebenzi kahle emazingeni okushisa aphezulu noma ezimweni ezigqwalisayo. Izakhiwo zayo zemishini zingase zithinteke yilezi zici, okungase kuholele ekunciphiseni ukuqina ngokuhamba kwesikhathi.

Ukuthembela enkambisweni yokwakha ebandayo kunganciphisa ubukhulu bezingxenye ezikhiqizwayo, okungaba yinkinga kwezinye izinhlelo zokusebenza ezisindayo.

Imibuzo Evame Ukubuzwa

Umbuzo 1. Kuyini i-EN 10219 S235JRH?

Ipayipi le-EN 10219iyindinganiso yaseYurophu echaza imininingwane yezingxenye ezingenalutho ezakhiwe ngesakhiwo ezihlanganisiwe. Isetshenziswa kabanzi embonini yokwakha ngenxa yezakhiwo zayo ezinhle kakhulu zemishini kanye nokushibilika kalula.

Umbuzo 2. Yiziphi izinzuzo zokusebenzisa i-S235JRH?

Insimbi ye-S235JRH inamandla aphezulu, i-ductility enhle kanye nokushintshwa okuhle kakhulu, ifanele ukusetshenziswa kwezakhiwo ezahlukahlukene. Izakhiwo zayo ezibandayo zivumela nobukhulu obuqondile kanye nesisindo esinciphile.

Umbuzo 3. Yiziphi izinhlelo zokusebenza ezifanele i-S235JRH?

Lokhu kusetshenziswa ngokuvamile ekwakhiweni kwezakhiwo, amabhuloho, nezinye izakhiwo lapho ukuqina nokuthembeka kubalulekile khona.

Umbuzo 4. Ngingaqinisekisa kanjani ukuthi ngithola i-S235JRH esezingeni eliphezulu?

Ukusebenza nomhlinzeki othembekile, njengefektri yethu eCangzhou, kuqinisekisa ukuthi uthola umkhiqizo ohlangabezana nezidingo eziqinile ze-EN 10219 standard.

Okwedlule: Ipayipi Lensimbi Elihlanganisiwe Eliqinile Elihlanganisiwe
