EN 10219 S355J0Hyii-welded epholileyoumbhobho wentsimbi yolwakhiwo ukuyaEN 10219, kunye nokomelela kwesivuno esincinci355 MPa(ubukhulu bodonga lombhobho ≤ 16 mm) kunye nempembelelo yamandla ubuncinane27 J ku-0°C.
Eyenziwe ngokusebenzisa i-welding yombane okanye i-arc ye-welding ye-arc ephantsi kwamanzi ngaphandle kwesidingo sonyango olulandelayo lokufudumala, zifanelekile kuluhlu olubanzi lwezicelo zezakhiwo kunye nobunjineli bezakhiwo, kubandakanywa amacandelo abalulekileyo okwakhiwa njengemfumba yokuxhasa isiseko.
I-BS EN 10219 nguMgangatho waseYurophu EN 10219 owamkelwa yi-UK.
Ibandakanya i-welded epholileyosetyhula, isikwere, uxande, kunye ne-ellipticalamacandelo akhiweyo angenanto.
CFCHS = icandelo elijikelezayo elenziwe ngokubanda;
CFRHS = indawo ebandayo eyenziwe isikwere okanye icandelo elinomngxuma elixande;
Sisebenza ngokukhethekileyo ekunikezeni icandelo elikwizinga eliphezulu lesetyhula elingenanto (CHS) umbhobho wentsimbi ukuhlangabezana neemfuno zakho zobunjineli ezahlukeneyo.
Ubunzima bodonga ≤40mm;
Isetyhula: Idayamitha yangaphandle ukuya kuthi ga kwi-2500 mm;
Amacandelo okwakhiwa kwemingxuma kuya kwenziwa ngeukuwelda kombane okanye ukuwelda kwe-arc emanzini (SAW).
I-EN 10219 amacandelo aholoholo aya kusiwa akhiwe ngendlela ebandayo ngaphandle konyango lobushushu olulandelayo, kodwa iiwelds zinokuba zikwimeko edityanisiweyo okanye ephathwe bubushushu.
Ukuba itekhnoloji ye-arc ye-welding ephantsi kwamanzi isetyenzisiwe, ingahlelwa kuyoLSAW(SAWL) (Longitudinal Submerged Arc Welding) kunyeSSAW(HSAW)(I-Spiral Submerged Arc Welding) ngokuxhomekeke kwicala le-weld seam.
LSAWineenzuzo ezibalulekileyo ekwenziweni kweUbubanzi obukhulukwayeimibhobho yentsimbi engqindililikwaye ilungele ngakumbi iimeko zesicelo apho amandla aphezulu, umgangatho, kunye nemilinganiselo echanekileyo ifunwa ngokungqongqo.
JCOEyinkqubo ebaluleke kakhulu kunye nommeli ekuveliseni umbhobho wensimbi we-LSAW.Igama lenkqubo livela kumanyathelo amane aphambili kwinkqubo yokwenza umbhobho: i-J-forming, i-C-forming, i-O-forming, kunye nokwandisa.
Singumvelisi wemibhobho yentsimbi yekhabhoni ekumgangatho ophezulu odityanisiweyo kunye nomthengisi ovela eChina, kunye nesitokhwe semibhobho yentsimbi engenamthungo, ekunika uluhlu olubanzi lwezisombululo zemibhobho yentsimbi!

Uvavanyo lwe-NDT (UT).
Uvavanyo lweHydrostatic
Sisebenzisa iindlela ezahlukeneyo zokuvavanya okungonakalisi kunye novavanyo loxinzelelo lwe-hydrostatic ukuqinisekisa amandla kunye nokuqina kombhobho ngamnye.Sibonelela abathengi bethu ngeemveliso zepayipi zentsimbi ezihlangabezana nemigangatho ephezulu yokhuseleko kunye nokuqinisekiswa komgangatho.
Iityhubhu zecandelo elinomgongxo ezenziwe ngokwe-EN 10219 ziyakwazi ukuwelda.
Xa udibanisa, ukuqhekeka okubandayo kwindawo ye-weld ngowona mngcipheko uphambili njengoko ubukhulu, inqanaba lamandla, kunye ne-CEV yemveliso yonyuka.Ukuqhekeka okubandayo kubangelwa yindibaniselwano yezinto ezininzi:
amanqanaba aphezulu e-hydrogen e-diffusible kwi-weld metal;
isakhiwo esine-brittle kwindawo echaphazelekayo kubushushu;
Ugxininiso olubalulekileyo loxinzelelo loxinzelelo kwindawo edibeneyo.
I-EN 10219 imibhobho yentsimbi ilungele ukugalela idiphu eshushu.Ukhetho lunokwenziwa ngokweemfuno zokwenyani.
Iya kuba nomphezulu ogudileyo ohambelana nendlela yokuvelisa esetyenziswayo;amaqhuma, i-voids, okanye i-grooves ye-longitudinal engekho nzulu evela kwinkqubo yokuvelisa ivumelekile ngaphandle kokuba ubukhulu babo obushiyekileyo buphakathi kokunyamezela.
Iziphene zobuso zingasuswa ngokusila, ngaphandle kokuba ubukhulu becandelo elilungisiweyo elinomngxuma abukho ngaphantsi kobuncinci obuvumelekileyo obuchazwe kwi-EN 10219-2.
