Ngohlobo Lwensimbi
Izinsimbi ezikhethekile ezingaluliwe nezihlanganisiwe.
Izinsimbi ezingaluliwe:
I-S235JRH, S275J0H, S275J2H, S355J0H, S355J2H, S355K2H,I-S275NH, S275NLH, S355NH, S355NLH.
Izinsimbi ezikhethekile ezihlanganisiwe:

Indlela elula yokuveza umehluko: izinhlobo zensimbi eziqukethe i-M noma 4 ziyi-alloys, futhi izakhiwo ze-alloying zensimbi zingabonakala ngokushesha.
Ngenqubo Yokukhiqiza
Izinqubo zokukhiqiza ezisetshenziswa ikakhulukazi ukukhiqiza amapayipi ensimbi ngokuya nge-BS EN 10219 zifaka phakathi.I-Electric Resistance Welding (ERW) kanye ne-Submerged Arc Welding (SAW).
I-SAW ingaphinde ihlukaniswe ibe yi-Longitudinal Submerged Arc Welding (LSAW) kanye ne-Spiral Submerged Arc Welding (SSAW) ngokusekelwe kuhlobo lwe-weld seam.
Nge-Cross-section Shape
I-CFCHS: Izingxenye eziyizigodi eziyiziyingi ezibandayo ezakhiwe;

Izinto Ezisetshenziswayo kanye Nezimo Zokulethwa
Izinsimbi ezingezona i-alloy
ngokweSithasiselo A, Esigoqiwe noma Esimisiwe/Esiyingiwe Esijwayelekile (N) saJR, J0, J2, kanye ne-K2izinsimbi;
Izinsimbi zokusanhlamvu ezinhle
NgokweSithasiselo B, Ukugingqa Okumisiwe/Okujwayelekile (N) kokuthiN kanye ne-NLizinsimbi;
NgokweSithasiselo B.M kanye ne-ML, izinsimbi zazigoqelwa nge-thermomechanically (M).
Izingxenye ezingenalutho zizolethwa zakhiwe ngendlela ebandayo ngaphandle kokwelashwa kokushisa okulandelayo ngaphandle kokuthi umthungo wokushisela ungase ube sesimweni esishiselwe njenge-welded noma esiphathwe ngokushisa.
Ezingxenyeni ezingenalutho ze-SAW ezingaphezu kuka-508 mm ngaphandle kobubanzi, kungase kudingeke ukuba kwenziwe umsebenzi wokubumba ofudumele, ongathinti izakhiwo zemishini, ukuze kuhlangatshezwane nezidingo zokubekezelela ngaphandle kokujikeleza.
I-BS EN 10219 Igama Lensimbi
Ingqungquthela yokuqamba amagama ye-BS EN 10219 iyafanaI-BS EN 10210, esebenzisa indinganiso ye-EN10027-1.
Ezingxenyeni ezingenalutho zensimbi engeyona i-alloy, igama lensimbi liqukethe
Isibonelo: Insimbi yesakhiwo (S) enamandla ashiwo ubuncane besivuno sogqinsi olungekho ngaphezu kuka-16 mm ka-275 MPa, enenani eliphansi lomthelela lamandla elingu-27 J ku-0 ℃(J), ingxenye engenalutho (H).

Ukubunjwa Kwekhemikhali kwe-BS EN 10219
Izinsimbi ezingezona i-alloy - Ukwakheka Kwamakhemikhali
Fine Grain Steels - Ukwakheka kwamakhemikhali
Uma insimbi ecolekile isetshenziswa njengempahla eluhlaza, ingahlukaniswa ibe ngu-M no-N ngokuya ngezimo zokulethwa, futhi izidingo zokwakheka kwamakhemikhali zalezi zinhlobo ezimbili zingase zehluke.
Lapho kunqunywa i-CEV kuzosetshenziswa ifomula elandelayo: CEV=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
Isimo se-Feedstock N
Isimo se-Feedstock M
Ukuchezuka Ekubunjweni Kwamakhemikhali
Izakhiwo Zemishini ye-BS EN 10219
Kufanele kwenziwe ngokuhambisana ne-EN 1000-2-1.Ukuhlolwa kufanele kwenziwe ebangeni lokushisa kusuka ku-10°C kuya ku-35°C.

Fine Grain Steels - Mechanical Properties
Uma insimbi enohlamvu oluhle isetshenziswa njengempahla eluhlaza, ingahlukaniswa ibe ngu-M no-N ngokwezimo zokulethwa, futhi izici zemishini zalezi zinhlobo ezimbili zingahluka.
Isimo se-Feedstock N
Isimo sempahla ye-Feedstock M
Izivivinyo Zomthelela
Ukuhlolwa komthelela kuzokwenziwa ngokuhambisana ne-EN 10045-1.
Inani elimaphakathi lesethi yezifanekiso ezintathu lizolingana noma libe likhulu kunevelu eshiwo.
Inani ngalinye lingase libe ngaphansi kwenani elishiwo, kodwa alikho ngaphansi kuka-70% walelo nani.
Ukuhlola Okungonakali
Lapho kwenziwa i-NDT kumashisela asezigabeni zesakhiwo esingenalutho, lezi zidingo ezilandelayo kufanele kuhlangatshezwane nazo.
Izigaba ezishiselwe ngogesi
Hlangana nenye yalezi zidingo ezilandelayo:
a) I-EN 10246-3 kuya kuzinga lokwamukela u-E4, ngaphandle kokuthi ishubhu elizungezayo/indlela yekhoyili ye-pancake ngeke ivunyelwe;
b) I-EN 10246-5 kuya ezingeni lokwamukelwa F5;
c) I-EN 10246-8 kuya ezingeni lokwamukela u-U5.
Izigaba Ezishiselwe I-Arc Engaphansi
Umthungo we-weld wezingxenye ezingenalutho ze-arc ezishiselwe ngaphansi kwamanzi uzohlolwa ngokuya nge-EN 10246-9 kuya ezingeni lokwamukela u-U4 noma nge-radiography ngokuhambisana ne-EN 10246-10 ngesigaba sekhwalithi yesithombe esingu-R2.
Ukubukeka Nokulungiswa Kwesici
Ukubukeka Kobuso
Izingxenye ezingenalutho zizoba nendawo ebushelelezi ehambisana nendlela yokukhiqiza esetshenzisiwe;amaqhuqhuva, ama-grooves noma ama-longitudinal grooves angashoni ngenxa yenqubo yokukhiqiza avunyelwe uma ukushuba okusele kungabekezelelwa.
Iziphetho zengxenye engenalutho zizosikwa ngokwezikwele ku-eksisi yomkhiqizo.
Ukulungiswa Kwesici
Amaphutha angaphezulu angasuswa ngokugaya inqobo nje uma ukujiya angekho ngaphansi kogqinsi oluncane oluvumelekile olushiwo ku-BS EN 10219-2 ngemva kokulungiswa.
Ezingxenyeni ezingenalutho zokusanhlamvu, ukulungiswa komzimba ngokushisela ngeke kuvunyelwe ngaphandle uma kuvunyelwene ngenye indlela.
Izinqubo zokulungisa i-weld zizohambisana nezidingo ze-EN ISO 15607, EN ISO 15609-1, kanye ne-EN ISO 15614-1.
I-Dimensional Tolerances
Ukubekezelelana kobukhulu kufanele kuhambisane nezidingo ezihambisanayo ze-EN 10219-2 futhi kuzonakwa ukwakheka kwesigaba esiphambanayo.
Ukubekezelela Isimo, UkuQopha kanye NeMisa
Ukubekezelela Ubude
Ukuphakama Kwe-Seam ye-SAW Weld
Ukubekezelela ukuphakama kwe-weld seam yangaphakathi nangaphandle yezingxenye ezingenalutho ze-arc ezishiselwe.
| Ubukhulu, T | Ubukhulu bobude be-weld bead, mm |
| ≤14,2 | 3.5 |
| >14,2 | 4.8 |
Kufakwe amagalani
I-BS EN 10219 Amashubhu angenalutho angafakwa uthayela oshisayo ukuze aphile impilo yesevisi.
Amashubhu angenalutho afakwa kubhavu oqukethe okungenani u-98% we-zinc ukuze akhe ungqimba olunothayela.
I-BS EN 10219 Ukumaka
Okuqukethwe kokumaka ipayipi lensimbi kufanele kuqukathe:
Igama lensimbi, isb EN 10219-S275J0H.
Igama noma uphawu lokuhweba lomkhiqizi.
Ikhodi kamazisi, isb inombolo ye-oda.
I-BS EN 10219 amashubhu ensimbi angamakwa ngezindlela ezahlukahlukene zokuqinisekisa ukukhonjwa kalula nokulandeleka, kungaba ngokudweba, ukugxiviza, amalebula okunamathela, noma amalebula engeziwe, angasetshenziswa ngawodwana noma ahlanganiswe.
Izinhlelo zokusebenza
Ukusetshenziswa kwezinga le-BS EN 0219 lihlanganisa zonke izindawo zezidingo zensimbi yesakhiwo.
Ukwakha:I-BS EN 10219 amapayipi ensimbi asetshenziswa kabanzi kumaphrojekthi wokwakha, njengokwakha amabhuloho, ukusekelwa kwesakhiwo sezakhiwo, njll.
Ukwakhiwa kwengqalasizinda: asetshenziswa ezinhlelweni zokonga amanzi, ukwakhiwa kwemigwaqo, izinhlelo zamapayipi, kanye neminye imiklamo yokwakha ingqalasizinda, njengamapayipi okukhipha amanzi, amapayipi amanzi, njalonjalo.
Ukukhiqiza: Lawa mapayipi ensimbi aphinde asetshenziswe ekwenzeni imishini, amasistimu okuthutha, nezinye izinhlelo zokusebenza zezimboni.
Ubunjiniyela bakamasipala: Ebunjiniyela bakamasipala basemadolobheni, i-BS EN 10219 amapayipi ensimbi ajwayelekile angasetshenziswa ukwenza ama- guardrails, ama-railing, imigoqo yomgwaqo, nokunye.
Umhlobiso wezakhiwo: Idizayini yobuhle namandla amashubhu ensimbi awenza abe yinto evamile esetshenziswa ekuhlobiseni kwezakhiwo, njengezitebhisi, ama-balustrade, amabakaki okuhlobisa, njll.
Kusukela yasungulwa ngo-2014, i-Botop Steel isibe ngumhlinzeki ohamba phambili wamapayipi ensimbi e-carbon eNyakatho neChina, eyaziwa ngomsebenzi wayo omuhle kakhulu, imikhiqizo esezingeni eliphezulu, nezisombululo ezibanzi.Uhlu olubanzi lwemikhiqizo yenkampani luhlanganisaamapayipi ensimbi angenamthungo, ERW, LSAW, kanye ne-SSAW, kanye nokufakwa kwamapayipi, ama-flange, nezinsimbi ezikhethekile.
Ngokuzibophezela okuqinile kukhwalithi, i-Botop Steel isebenzisa izilawuli eziqinile nokuhlola ukuze iqinisekise ukwethembeka kwemikhiqizo yayo.Ithimba layo elinolwazi lihlinzeka ngezixazululo eziqondene nawe kanye nokwesekwa kochwepheshe, ngokugxila ekwanelisekeni kwamakhasimende.
