I-BS EN 10210 S275J0Hiyingxenye yensimbi yesakhiwo engenalutho eshisiwe eyakhiwe eyakhiwe ukuzeI-BS EN 10210ezinhlobonhlobo zomumo wesigaba esiyindilinga, isikwele, esingunxande, noma esisaqanda.
Impahla ye-S275J0H ibonakala ngamandla amancane okukhiqiza angama-275 MPa ekushubeni okungengaphezu kuka-16 mm;amandla awo amancane omthelela ubuncane obungu-27 J ku-0℃.
I-S275J0H ingeyohlobo lwensimbi ye-carbon, inombolo yensimbi1.0149, enezakhiwo ezinhle zesakhiwo nokucubungula, ikakhulukazi ezisetshenziselwa izakhiwo zokwakha, kodwa futhi ezisetshenziselwa izingxenye ezingathwali umthwalo, zinganikeza ekugcineni ukuqina kwesakhiwo nokuqina okusekelwe ekufezeni izinzuzo eziphansi.
Qaphela: Zonke izidingo ku-BS EN 10210 nazo ziyasebenza ku-EN 10210 ngakho-ke aziphindwa lapha.
Ukuqokwa kwamabanga ku-BS EN 10210 kwabelwa ngokuya nge-EN 10027-1 futhi izinombolo zensimbi zinikezwa ngokuya nge-EN 10027-2.

Sisebenza ngokukhethekile ekuhlinzekeni imininingwane ehlukahlukene ye-Round Hollow Structural Steel Pipe, uma unezidingo, sicela ukhululeke ukuxhumana nathi, sibheke ngabomvu ukubambisana nawe!
Amapayipi ensimbi ashiselwe i-LSAW akhiqizwa ngokuyinhloko ngokwakha amapuleti ensimbi abe amashubhu kusetshenziswa inqubo yokubumba ye-JCOE, elandelwa ukushisela kusetshenziswa i-arc engaphansi kwamanzi ezinhlangothi ezimbili (I-DSAW) ubuchwepheshe bokushisela, futhi siphothulwa ngokuhlolwa nokwelashwa okuningi.
Ukhetha kanjani inqubo yokukhiqiza efanele?Uyini umehluko kanye nezinzuzo zepayipi lensimbi engenamthungo, i-LSAW, i-arc welding engaphansi kwamanzi, kanye nokushisela kwe-arc engaphansi kwamanzi?Futhi ingakanani ububanzi benqubo ngayinye?Ungachofoza isixhumanisi esilandelayo ukuze uyibuke.
Izimfanelo JR,J0, J2 kanye ne-K2 -kushisa kuphelile;
Izimfanelo N kanye ne-NL - zijwayelekile.Okujwayelekile kufaka phakathi ukugoqwa okujwayelekile.

Izakhiwo zemishini ye-BS EN 10210 zifaka amandla esivuno, amandla aqinile, ubude, kanye nezakhiwo zomthelela.
Izingxenye ezingenalutho zizoba nendawo ebushelelezi ehambisana nendlela yokukhiqiza esetshenzisiwe;amaqhuqhuva, izimbotshana, noma imisele engashoni yelongitudinal ewumphumela wenqubo yokukhiqiza ivumelekile, inqobo nje uma ukujiya kungaphakathi kokubekezelelwa.
I-TS EN 10210 Indawo yamapayipi ensimbi ifanele ukugalela idiphu eshisayo.
I-EN 10210 ayidingi ukuhlolwa kwengcindezi ye-hydrostatic yamapayipi ensimbi.
Lokhu kungenxa yokuthi imikhiqizo esezingeni ye-EN 10210 isetshenziselwa ikakhulukazi izinjongo zesakhiwo hhayi amasistimu wamapayipi adinga ukucindezelwa.
Uma kudingeka ukuhlolwa kwengcindezi ye-hydrostatic, ireferensi ingenziwa ku-EN 10216 (amashubhu ensimbi engenamthungo) noma i-EN 10217 (amashubhu ensimbi ashiselwe).
Asikho isidingo esiyisibopho esilinganisweni sokwenza i-NDT kumapayipi ensimbi esigaba esingenalutho.
Uma i-NDT yenziwa kumapayipi ensimbi ashiselwe, izidingo ezilandelayo zingabhekiselwa kuzo.
Izigaba ezishiselwe ngogesi
Okwamashubhu ensimbi ayindilinga angenalutho yi-ERW.
Ungakhetha eyodwa kwezilandelayo izindlela zokuhlola zokuhlola.
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
Okwamashubhu ensimbi ayindilinga angenalutho yi-LSAW ne-SSAW.
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.
Ukuze uthole ulwazi oluthe xaxa mayelana nezidingo ezihlobene nokubekezelelana kwe-dimensional,sicela uchofoze lapha ukuze uthole ulwazi olwengeziwe.
I-EN 10025 - S275J0;
I-JIS G3106 - SM400B;

Lapho kukhethwa i-EN 10210 S275J0H okulingana, ukuqhathanisa okuningiliziwe kokwakheka kwamakhemikhali kanye nezakhiwo zemishini kufanele kwenziwe ukuze kuqinisekiswe ukuthi into ekhethiwe ihlangabezana nezidingo ezithile zephrojekthi.
Kusukela yasungulwa ngo-2014,Insimbi ye-Botopisibe ngumphakeli ohamba phambili wepayipi lensimbi ye-carbon eNyakatho yeChina, elaziwa ngomsebenzi omuhle kakhulu, imikhiqizo yekhwalithi ephezulu, nezixazululo ezibanzi.
Le nkampani inikeza izinhlobonhlobo zamapayipi ensimbi ye-carbon nemikhiqizo ehlobene, okuhlanganisa ipayipi lensimbi engenamthungo, i-ERW, i-LSAW, ne-SSAW, kanye nohlu oluphelele lokufakwa kwamapayipi nama-flange.Imikhiqizo yayo ekhethekile ihlanganisa ama-alloys asezingeni eliphezulu kanye nezinsimbi ezingenasici ze-austenitic, ezenzelwe ukuhlangabezana nezidingo zamaphrojekthi ahlukahlukene wamapayipi.
