Tianjin Yuantai Derun Iqela JCOE Φ1420 enkuluumbhobho we-lsawiyunithi iyasebenza ukuvala umsantsa kwimarike yaseTianjin
I-JCOE yiteknoloji yokwenza imibhobho yokuvelisa imibhobho yentsimbi enobubanzi obukhulu, esekelwe kwinkqubo yokuvelisa i-arc welding engaphantsi komhlaba enamacala amabini, apho imveliso igotywa, igotywe kwangaphambili, igotywe, ithungwe, idityaniswe ngaphakathi, idityaniswe ngaphandle, ilungiswe, kwaye iphele ngokutyibilikayo kwiinkqubo ezininzi. Inkqubo yokwenza ingahlulwa ibe ngamanyathelo e-N+1 (i-N yi-integer elungileyo), apho ipleyiti yentsimbi inikwa ngokuzenzekelayo kwaye igotywe ngokutyibilikayo kumanyathelo amiselweyo ukuze kufezekiswe ukwakheka kwe-CNC okuqhubekayo kwe-JCO. Ipleyiti yentsimbi ingena kumatshini wokwenza kwicala elinqamlezileyo, kwaye iqhutywa yitroli yokutya ukuze kuqhutywe inqanaba lokuqala lamanyathelo e-N/2 okugoba ngamanyathelo amaninzi ukuze kufezekiswe ukwakheka kwe-"J" kwesiqingatha sokuqala sepleyiti yentsimbi; isigaba sesibini kuqala senza ipleyiti yentsimbi eyenziwe "J" ikhawuleze igqithise ukuya kwindawo echaziweyo enqamlezileyo, ukusuka kwelinye icala lepleyiti yentsimbi engabumbekanga ukuya kwelinye inyathelo le-N/2 lokugoba ngamanyathelo amaninzi, ukuze kufezekiswe isiqingatha sesibini sokwenziwa kwepleyiti yentsimbi, ukuze kugqitywe ukwakheka kwe-"C"; Ekugqibeleni, inxalenye esezantsi ye-"C" pipe billet ukugoba kanye ukuze kufezekiswe "Inyathelo ngalinye lokushicilela lisekelwe kumgaqo osisiseko wokugoba okuneengongoma ezintathu."
Umbhobho wentsimbi we-LSAWbadlala indima ebalulekileyo kwi-bigumbhobho womgca we-lsawiiprojekthi, iiprojekthi zokuhambisa amanzi negesi, ukwakhiwa kwenethiwekhi yemibhobho yasezidolophini, ukufakwa kweebhulorho, ukwakhiwa komasipala kunye nokwakhiwa kwedolophu. Kwiminyaka yakutshanje, njengohlobo olutsha lwenkqubo yokwakha yokonga amandla kunye nokusingqongileyo, isakhiwo sesakhiwo sentsimbi siye sabizwa ngokuba "sisakhiwo esiluhlaza" senkulungwane yama-21. Kwisicwangciso soyilo lwesakhiwo esiphakamileyo nesiphakamileyo kakhulu ukunika kuqala ukusetyenziswa kwenkqubo yesakhiwo sentsimbi okanye sekhonkrithi yentsimbi, izakhiwo ezinkulu ezisebenzisa ngokukhutheleyo isakhiwo segridi yendawo, isakhiwo se-truss esinemilinganiselo emithathu, isakhiwo se-membrane yekhebula kunye nenkqubo yesakhiwo esixineneyo, ezi ziipayipi zentsimbi ekwakhiweni kweemeko ezininzi zokusetyenziswa, kwaye imfuno yepayipi yentsimbi enobubanzi obukhulu, enodonga olukhulu nayo inyukile kakhulu. Enyanisweni,imibhobho ye-lsaw kunye ne-hsaweziveliswe yiYuantai Derun Steel Pipe Manufacturing Group zisetyenziswa kakhulu. Njengemveliso ekumgangatho ophezuluumenzi wepayipi ye-lsaweTshayina, iYuantai Derun ibandakanyeka ekuboneleleni ngeemibhobho zentsimbi kwiiprojekthi ezininzi ezinkulu.
Kutshanje, iTianjin Yuantai Derun Steel Pipe Manufacturing Group iphumelele isiqinisekiso esinxulumene neUmbhobho we-lsaw we-API 5L, kwaye iza kusetyenziswa kakhulu kwiindawo ezahlukeneyo kwixesha elizayo. Iimveliso eziphambili ziqukaumbhobho wentsimbi yekhabhoni ye-lsaw, umbhobho wentsimbi ye-lsaw enobubanzi obukhulukunyeumbhobho wentsimbi odibeneyo we-lsaw.
Iyunithi ye-JCOEΦ1420 yeTianjin Yuantai Derun Steel Pipe Manufacturing Group inokuvelisa iinkcukacha eziqala kwi-Φ355.6mm ukuya kwi-Φ1420mm ububanzi kunye nobukhulu bodonga obufikelela kwi-50mm, nto leyo eya kuzalisa umsantsa kwimarike yeTianjin yeemveliso ezinjalo xa isetyenziswa kwaye inokunciphisa kakhulu ixesha lokukhokela loku-odola iipayipi ezinkulu, ezijikelezileyo nezinodonga olukhulu kunye nezingxande. I-welding ye-arc engaphantsi komhlaba enamacala amabini, ipayipi enkulu edibeneyo ende ingasetyenziselwa ngokuthe ngqo ukuhanjiswa kweoyile negesi, ipayipi yentsimbi ye-JCOE isetyenzisiwe kakhulu kwiprojekthi yesizwe "yokuhanjiswa kwegesi eNtshona-Mpuma", ngelixa njengombhobho wentsimbi olwakhiwo ungasetyenziswa ekwakhiweni kwesakhiwo sentsimbi ephezulu kakhulu, ukongeza ekusebenziseni inkqubo "ejikelezayo ukuya kwisikwere" ingacutshungulwa ibe yidayamitha enkulu kakhulu. Ukongeza, inkqubo "ejikelezayo ukuya kwisikwere" ingacutshungulwa ibe yipayipi yentsimbi engxande enodonga olukhulu kakhulu, enokusetyenziswa kwiindawo zokuzonwabisa ezinkulu kunye nokuveliswa koomatshini abanzima nezixhobo.
