EN 10210 S355J2Hyintsimbi yecandelo elinomngxuma elishushu eligqityiweyo ngokwesakhiwoEN 10210kunye namandla amancinci okuvunwa kwe-355 MPa (ubunzima bodonga ≤ 16 mm) kunye neempawu zempembelelo ezintle kumaqondo okushisa aphantsi ukuya kwi-20 ° C, okwenza kube yinto efanelekileyo yokusetyenziswa kuluhlu olubanzi lwezakhiwo kunye nezakhiwo zobunjineli.
Ewe, EN 10210 =I-BS EN 10210.
I-BS EN 10210 kunye ne-EN 10210 ziyafana kumxholo wobugcisa kwaye zombini zimele imigangatho yaseYurophu yoyilo, yokwenziwa, kunye neemfuno zamacandelo angaphakathi kwe-thermoformed.
I-BS EN 10210 yinguqulelo eyamkelwe e-UK, ngelixa i-EN 10210 ingumgangatho waseYurophu ngokubanzi.Iibhodi ezahlukeneyo zokumisela umgangatho zingenza isimaphambili somgangatho ngezifinyezo zesizwe, kodwa umxholo ongundoqo womgangatho uhlala ungaguquguquki.
Amacandelo angenanto angahlelwa njengesetyhula, isikwere okanye uxande, okanye i-elliptical.
Kwakhona ngenxa yokuba yinkqubo egqityiweyo eshushu ngokuhambelana ne-EN 10210, esi sishunqulelo silandelayo sinokusetyenziswa.
HFCHS= amacandelo ashushu agqityiweyo asetyhula;
HFRHS= isikwere esigqityiweyo esishushu okanye amacandelo anomngxuma oxande;
HFEHS= kushushu kugqitywe amacandelo angumngxunya we-elliptical.
Umjikelo: Idayamitha yangaphandle ukuya kuthi ga kwi-2500 mm;
Ubunzima beendonga ukuya kuthi ga kwi-120 mm.
Kakade ke, akukho ndlela yokuvelisa iityhubhu zale sayizi kunye nobukhulu bodonga ukuba inkqubo ye-welding ye-ERW isetyenziswa.
I-ERW inokuvelisa iityhubhu ukuya kwi-660mm kunye nobukhulu bodonga obuyi-20mm.
Isinyithi sinokwenziwa nokuba kusetyenziswe aingenamthungo okanye i-weldinginkqubo.
Phakathi kweiinkqubo welding, iindlela ze-welding eziqhelekileyo ziqukaERW(ukumelana nombane welding) kunyeSAW(i-arc iwelding ephantsi kwamanzi).
Phakathi kwabanye,ERWbubuchule bokuwelda obudibanisa iindawo zentsimbi kunye ngobushushu obuxhathisayo kunye noxinzelelo.Obu buchule busebenza kuluhlu olubanzi lwezinto kunye nobukhulu kwaye buvumela inkqubo ye-welding esebenzayo.
SAW, kwelinye icala, yindlela ye-welding esebenzisa i-granular flux ukugubungela i-arc, ebonelela ngokungena nzulu kunye nomgangatho ongcono we-weld kwaye ifaneleke ngokukodwa ukuwelda iipleyiti ezishinyeneyo.
Okulandelayo, yinkqubo ye-ERW, eyindlela yokuvelisa esebenza kakhulu esetyenziswa ngokubanzi ukuvelisa uluhlu olubanzi lweetyhubhu zentsimbi kunye neeprofayili.
Kufuneka kuqatshelwe ukuba kumacandelo angaxutywanga kunye ne-fine-grain-grain hollow eyenziwe yinkqubo ye-welding, ukulungiswa kwe-welds akuvumelekanga ngaphandle kwe-arc welding.
Iimpawu JR, JO, J2 kunye neK2 - kushushu kugqityiwe,
Ubuncinci amandla okuvelisa i-S355J2H yensimbi yombhobho ayilungiswanga, iya kutshintsha kunye nobukhulu bodonga oluhlukeneyo.
Ngokukodwa, amandla okuvelisa i-S355J2H abekwe ngokomgangatho xa ubukhulu bodonga bungaphantsi okanye bulingana ne-16mm, kodwa xa ubuninzi bodonga bunyuka, amandla okuvelisa aya kuncitshiswa, ngoko akusiyo yonke i-S355J2H ipayipi yensimbi inokufikelela kwimveliso encinci. amandla e355MPa.
