EN 10219 S355J0Hyii-weld eyenziwe ngokubandayoumbhobho wesinyithi ongenanto oya kwisakhiwoEN 10219, ngamandla amancinci okuvelisa355 MPa(ubukhulu bodonga lombhobho ≤ 16 mm) kunye namandla okuchaphazela ubuncinane27 J kwi-0°C.
Zenziwe kusetyenziswa iindlela zokuwelda ngombane okanye iindlela zokuwelda ezifakwe kwi-arc ngaphandle kwesidingo sonyango lobushushu olulandelayo, zifanelekile kwiintlobo ngeentlobo zezicelo zokwakha nezobunjineli, kuquka izinto ezibalulekileyo zokwakha ezifana neenqwaba zenkxaso yesiseko.
I-BS EN 10219 yi-European Standard EN 10219 eyamkelwe yi-UK.
Ibandakanya i-welded eyenziwe ngokubandaisangqa, isikwere, uxande, kunye ne-ellipticaliindawo ezingenanto zesakhiwo.
I-CFCHS = icandelo elijikelezayo eliyimbumba elibunjiweyo;
I-CFRHS = icandelo elinomqolo okanye elinomqolo eliyimiqolomba;
Siziingcali ekunikezeni icandelo elijikelezayo elikumgangatho ophezulu (I-CHS) umbhobho wentsimbi ukuhlangabezana neemfuno zakho ezahlukeneyo zobunjineli.
Ubukhulu bodonga ≤40mm;
Isangqa: Ububanzi bangaphandle ukuya kuthi ga kwi-2500 mm;
Iindawo ezingenanto zesakhiwo mazibe zezokwakhiwa nguukuwelda ngombane okanye ukuwelda nge-arc engaphantsi komhlaba (SAW).
I-EN 10219 iindawo ezingenanto mazihanjiswe zenziwe ngendlela ebandayo ngaphandle konyango lobushushu olulandelayo, kodwa ii-welds zisenokuba zikwimeko edibeneyo okanye ephethwe ngobushushu.
Ukuba kusetyenziswa iteknoloji yokuwelda ye-arc engaphantsi komhlaba, ingahlulwahlulwa ngokwezigabaI-LSAW(I-SAWL(I-Longitudinal Submerged Arc Welding) kunyeI-SSAW(I-HSAW(Ukuwelda kwe-Arc efakwe kwi-Spiral Submerged) kuxhomekeke kwicala lomthungo wokuwelda.
I-LSAWineenzuzo ezibalulekileyo ekwenziweni kweubukhulu obukhulukwayeimibhobho yentsimbi enodonga oluqinileyokwaye ifanelekile ngokukodwa kwiimeko zokusetyenziswa apho kufuneka khona amandla aphezulu, umgangatho, kunye nobukhulu obuchanekileyo.
I-JCOEyinkqubo ebaluleke kakhulu nemeleyo ekuvelisweni kombhobho wentsimbi we-LSAW. Igama lenkqubo livela kumanyathelo amane aphambili kwinkqubo yokwenza umbhobho: ukwakheka kwe-J, ukwakheka kwe-C, ukwakheka kwe-O, kunye nokwandiswa.
Singumvelisi kunye nomthengisi wemibhobho yentsimbi yekhabhoni edityanisiweyo ekumgangatho ophezulu evela eTshayina, kwaye sikwangumthengisi wemibhobho yentsimbi engenamthungo, sikunika uluhlu olubanzi lwezisombululo zemibhobho yentsimbi!

Ukuphambuka kohlalutyo lwemveliso kwimida echazwe kuhlalutyo lokuphosa kuya kuhambelana neemfuno ezingezantsi.
Ukunciphisa uxinzelelo oluphezulu kwiqondo lobushushu elingaphezulu kwama-580°C okanye ngaphezulu kweyure enye kunokukhokelela ekuwohlokeni kweempawu zoomatshini.
Uvavanyo lokuxinana kufuneka lwenziwe ngokuhambelana ne-EN 10002-1.
Uvavanyo lwempembelelo kufuneka lwenziwe ngokuhambelana ne-EN 10045-1.
Iimpawu zempembelelo ziqinisekiswa kuphela xa uKhetho 1.3 luchaziwe.
c Kwiisayizi zecandelo D/T < 15 (esetyhula) kunye (B+H)/2T < 12,5 (isikwere kunye noxande) ubuncinci bobude buncitshiswa nge-2.
d Ubukhulu < 3 mm jonga ku-9.2.2.
e Ukuze ufumane iipropati zempembelelo zeziqwenga zovavanyo zecandelo elincitshisiweyo jonga ku-6.7.2.
AmanqakuUvavanyo lwempembelelo alufuneki xa ubukhulu obuchaziweyo buyi-<6mm.
Ii-welds ezikwiindawo ezingenanto ezidityanisiweyo ze-arc ezingaphantsi komhlaba kufuneka zivavanywe ngokuhambelana ne-EN 10246-9 ukuze zifumane udidi lokwamkelwa lwe-U4 okanye nge-radiographic ngokuhambelana ne-EN 10246-10 ukuze zifumane udidi lomgangatho womfanekiso lwe-R2.

Uvavanyo lwe-Hydrostatic
Sisebenzisa iindlela ezahlukeneyo zokuvavanya ezingatshabalalisiyo kunye novavanyo loxinzelelo lwe-hydrostatic ukuqinisekisa amandla kunye nokuqina kombhobho ngamnye. Sibonelela abathengi bethu ngeemveliso zombhobho wentsimbi ezihlangabezana nemigangatho ephezulu yokhuseleko kunye nokuqinisekiswa komgangatho.
Iityhubhu zecandelo elingenanto ezenziwe ngokwe-EN 10219 ziyaxhunyelelwa.
Xa kudityaniswa, ukuqhekeka okubandayo kwindawo yokudityaniswa kwempahla yeyona mngcipheko uphambili njengoko ubukhulu, amandla, kunye ne-CEV yemveliso isanda. Ukuqhekeka okubandayo kubangelwa kukudibana kwezinto ezininzi:
amanqanaba aphezulu e-hydrogen esasazekayo kwisinyithi esitshixiweyo;
isakhiwo esibuthathaka kwindawo echaphazelekileyo bubushushu;
uxinzelelo olubalulekileyo loxinzelelo lokuxinana kwijoyinti edibeneyo.
Imibhobho yentsimbi ye-EN 10219 ifanelekile kwi-hot dip galvanizing. Ukukhetha kungenziwa ngokweemfuno zokwenyani.
Kufuneka ibe nomphezulu ogudileyo ohambelana nendlela yokwenziwa esetyenzisiweyo; amaqhuma, imingxunya, okanye imingxunya emide enganzulu evela kwinkqubo yokwenziwa iyavumeleka ukuba ubukhulu bayo obuseleyo buxhomekeke kumlinganiselo wokwenziwa.
Iziphene zomphezulu zingasuswa ngokusila, ukuba ubukhulu becandelo elinomgodi olulungisiweyo abungaphantsi kobukhulu obuvumelekileyo obuchazwe kwi-EN 10219-2.
