I-BS EN 10210 S275J0Hingxenye yensimbi eyakhiwe ngomumo eqediwe ngokushisa eyenziwe nge-I-BS EN 10210ngezimo ezahlukahlukene zesigaba esiyindilinga, esiyisikwele, esingunxande, noma esiyisiyingi.
Izinto ze-S275J0H zibonakala ngamandla okukhiqiza okungenani angu-275 MPa ngobukhulu obungadluli ku-16 mm; amandla ayo okuthinta amancane okungenani angu-27 J ku-0℃.
I-S275J0H ingeyohlobo lwensimbi yekhabhoni, inombolo yensimbi1.0149, enezakhiwo ezinhle zokwakha kanye nokucubungula, ezisetshenziswa kakhulu ezakhiweni zokwakha, kodwa futhi ezisetshenziselwa izingxenye ezingathwali umthwalo, zinganikeza ukugcina ukuzinza kwesakhiwo nokuqina ngokusekelwe ekuqaphelisweni kwezinzuzo eziphansi.
Qaphela: Zonke izidingo ku-BS EN 10210 ziyasebenza naku-EN 10210 ngakho-ke aziphindaphindwa lapha.
Izikhundla zebanga ku-BS EN 10210 zinikezwa ngokuhambisana ne-EN 10027-1 kanti izinombolo zensimbi zinikezwa ngokuhambisana ne-EN 10027-2.

Singochwepheshe ekuhlinzekeni ngemininingwane ehlukahlukene ye-Round Hollow Structural Steel Pipe, uma unezidingo, sicela ukhululeke ukuxhumana nathi, silangazelela ukubambisana nawe!
Izinga le-BS EN 10210 livumela izinqubo eziningana zokukhiqiza ukuthi zisetshenziswe ukukhiqiza izingxenye ezingenalutho ezakhiweni, kufaka phakathi izinqubo ezingenamthungo nezihlanganisiwe. Ngaphakathi kwenqubo yokushisela, izindlela ezivamile zifaka phakathiI-LSAW(SAWL), SSAW (I-HSAW), kanyeI-ERW.
Amapayipi ensimbi ahlanganisiwe e-LSAW akhiqizwa kakhulu ngokwakha amapuleti ensimbi abe amashubhu kusetshenziswa inqubo yokubumba ye-JCOE, kulandelwe ukushisela kusetshenziswa i-arc engaphansi kwamanzi enamacala amabili (I-DSAW) ubuchwepheshe bokushisela, futhi kwaqedwa ngokuhlolwa okuningana kanye nokwelashwa.
Uyikhetha kanjani inqubo yokukhiqiza efanele? Yimiphi umehluko nezinzuzo zepayipi lensimbi elingenamthungo, i-LSAW, ukushisela i-arc engaphansi komhlaba, kanye nokushisela i-arc engaphansi komhlaba? Futhi ububanzi bosayizi benqubo ngayinye bungakanani? Ungachofoza isixhumanisi esilandelayo ukuze usibuke.
Ikhwalithi JR,J0, J2 kanye ne-K2 -kuqediwe ukushisa;
Izimfanelo N kanye ne-NL - ezijwayelekile. Ezijwayelekile zifaka phakathi ezigoqiwe ezijwayelekile.

Izakhiwo zemishini ze-BS EN 10210 zifaka phakathi amandla okukhiqiza, amandla okudonsa, ukunwebeka, kanye nezakhiwo zokuthinta.
Izingxenye ezingenalutho kumele zibe nobuso obubushelelezi obuhambisana nendlela yokukhiqiza esetshenzisiwe; amaqhubu, izimbobo, noma imisele emide engajulile evela enkambisweni yokukhiqiza iyavunyelwa, uma nje ubukhulu bungaphakathi kokubekezelelwa.
I-EN 10210 Izindawo zamapayipi ensimbi zilungele ukugaya nge-hot dip.
I-EN 10210 ayidingi ukuhlolwa kwengcindezi ye-hydrostatic yamapayipi ensimbi.
Lokhu kungenxa yokuthi imikhiqizo ejwayelekile ye-EN 10210 isetshenziselwa kakhulu izinjongo zesakhiwo hhayi izinhlelo zamapayipi ezidinga ukucindezelwa.
Uma kudingeka ukuhlolwa kwengcindezi ye-hydrostatic, kungenziwa inkomba ye-EN 10216 (amashubhu ensimbi angenamthungo) noma i-EN 10217 (amashubhu ensimbi ahlanganisiwe).
Akukho mfuneko ephoqelekile ejwayelekile yokwenza i-NDT kumapayipi ensimbi angenazo izikhala.
Uma i-NDT yenziwa emapayipini ensimbi ahlanganisiwe, izidingo ezilandelayo zingabhekiselwa kuzo.
Izingxenye Ezihlanganisiwe Zikagesi
Amashubhu ensimbi ayindilinga anendawo engenalutho yi-ERW.
Ungakhetha enye yezindlela ezilandelayo zokuhlola.
a) EN 10246-3 ezingeni lokwamukelwa E4, ngaphandle kokuthi indlela ye-rotary tube/pancake coil ngeke ivunyelwe;
b) EN 10246-5 ezingeni lokwamukelwa F5;
c) EN 10246-8 kuya ezingeni lokwamukelwa U5.
Izingxenye Ezihlanganisiwe Ze-Arc Ecwilisiwe
Amashubhu ensimbi ayindilinga anendawo engenalutho yi-LSAW ne-SSAW.
Umthungo wokushisela wezingxenye ezingenalutho ezihlanganisiwe ze-arc engaphansi komhlaba kufanele uhlolwe ngokuhambisana ne-EN 10246-9 kuya ezingeni lokwamukelwa le-U4 noma nge-rayography ngokuhambisana ne-EN 10246-10 ngeklasi yekhwalithi yesithombe R2.
Ukuze uthole ulwazi oluningiliziwe mayelana nezidingo ezihlobene nokubekezelelana kobukhulu,sicela uchofoze lapha ukuthola ulwazi olwengeziwe.

Uma ukhetha okulinganayo kwe-EN 10210 S275J0H, kufanele kwenziwe ukuqhathaniswa okuningiliziwe kokwakheka kwamakhemikhali kanye nezakhiwo zemishini ukuqinisekisa ukuthi izinto ezikhethiwe ziyahlangabezana nezidingo ezithile zephrojekthi.
Selokhu yasungulwa ngo-2014,Insimbi yeBotopisibe ngumhlinzeki ohamba phambili wamapayipi ensimbi yekhabhoni eNyakatho yeShayina, eyaziwa ngenkonzo enhle kakhulu, imikhiqizo esezingeni eliphezulu, kanye nezixazululo eziphelele.
Le nkampani inikeza amapayipi ahlukahlukene ensimbi yekhabhoni kanye nemikhiqizo ehlobene nayo, kufaka phakathi ipayipi lensimbi elingenamthungo, i-ERW, i-LSAW, kanye ne-SSAW, kanye nohlu oluphelele lwezihlanganisi zamapayipi nama-flange. Imikhiqizo yayo ekhethekile ifaka phakathi ama-alloy ebanga eliphezulu kanye nezinsimbi ezingagqwali ze-austenitic, ezenzelwe ukuhlangabezana nezidingo zamaphrojekthi ahlukahlukene amapayipi.
