Tianjin Yuantai Derun Iqela JCOE Φ1420 enkulundabona ipayipiiyunithi ifakwe ekusebenzeni ukugcwalisa isithuba kwimarike yaseTianjin
I-JCOE ngumbhobho wokwenza itekhnoloji yokuvelisa imibhobho yentsimbi engqindilili engqindilili, esekelwe kwinkqubo yokuvelisa i-arc entywiliselweyo, apho imveliso igaywa, igobe kwangaphambili, igobe, ithungelwe, idityaniswe ngaphakathi, idityaniswe ngaphandle, yolule, kwaye iphelile kwiinkqubo ezininzi.Inkqubo yokwenza inokwahlulwa ibe ngamanyathelo e-N+1 (u-N yinani elipheleleyo elipheleleyo), kunye nepleyiti yentsimbi ezondliwa ngokuzenzekelayo kwaye igotywe ngokunqamlezayo kumanyathelo amiselweyo ukufikelela kwi-CNC eqhubekayo yokwenza i-JCO.Ipleyiti yensimbi ingena kumatshini wokwenza i-transverse direction, kwaye iqhutywe yitrolley yokutya ukuze iqhube inqanaba lokuqala le-N / 2 amanyathelo okugoba ngamanyathelo amaninzi ukufezekisa i-"J" yokwenza isiqingatha sokuqala seplate yensimbi. ;isigaba sesibini kuqala yenza "J" ipleyiti equlunqwe ipleyiti yentsimbi ngokukhawuleza ukutya ezinqamlezayo ukuya ezinqamlezileyo Isikhundla Esichaziweyo, ukusuka kwelinye icala ipleyiti yentsimbi unformed enye N / 2 amanyathelo ukugoba multi-inyathelo, ukuphumeza isiqingatha sesibini sentsimbi. ukwenza ipleyiti, ukugqiba "C" ukwenza;Ekugqibeleni, inxalenye engezantsi ye-billet ye-billet "C" igoba kanye ukufezekisa "Inyathelo ngalinye lokushicilela lisekelwe kumgaqo osisiseko wokugoba amanqaku amathathu.
LSAW umbhobho wentsimbiukudlala indima ebalulekileyo enkulundabona umbhobho womgcaiiprojekthi, iiprojekthi zothumelo lwamanzi negesi, ulwakhiwo lothungelwano lwemibhobho yasezidolophini, ukufunjwa kwebhulorho, ulwakhiwo lukamasipala kunye nolwakhiwo lwasezidolophini.Kwiminyaka yakutshanje, njengohlobo olutsha lwenkqubo yokulondoloza amandla kunye nokusingqongileyo, isakhiwo sentsimbi siye sanconywa njenge "isakhiwo esiluhlaza" senkulungwane yama-21.Kwinqanaba eliphezulu kunye ne-ultra-high-ukuphakama kwesakhiwo soyilo lokuyila ukubeka phambili ekusetyenzisweni kwensimbi okanye inkqubo ye-concrete ye-concrete, izakhiwo ezinkulu ezisebenzayo zisebenzisa isakhiwo segridi yesithuba, isakhiwo se-truss esinemigangatho emithathu, isakhiwo se-cable membrane. kunye nenkqubo yesakhiwo egxininiswe ngaphambili, ezi zingumbhobho wensimbi ekwakhiweni kweemeko ezininzi zesicelo, kunye ne-diameter enkulu, i-ultra-thick-walled steel pipe imfuno iye yanda kakhulu.Ndabona kwaye ndabona imibhobhoeveliswe yiYuantai Derun Steel Pipe Manufacturing Group isetyenziswa ngokubanzi.Njengomgangatho ophezulundabona umenzi wombhobhoe China, Yuantai Derun ibandakanyeka kunikezelo lwemibhobho yentsimbi kwiiprojekthi ezininzi ezinkulu.
Kutshanje, iTianjin Yuantai Derun Steel Pipe Manufacturing Group idlulise isatifikethi esinxulumeneAPI 5L lsaw umbhobho, kwaye iya kusetyenziswa ngokubanzi kwiinkalo ezahlukeneyo kwixesha elizayo.Imveliso eziphambili ziqukaNdabona umbhobho wentsimbi yekhabhoni, ubukhulu obukhulu lsaw umbhobho wentsimbi, kwayeNdabona umbhobho wentsimbi odityanisiweyo.
Iyunithi ye-JCOEΦ1420 ye-Tianjin Yuantai iDrun Steel Pipe Manufacturing Group inokuvelisa iinkcukacha ukusuka ku-Φ355.6mm ukuya ku-Φ1420mm ububanzi kunye nokuya kuthi ga kwi-50mm kubukhulu bodonga, okuya kugcwalisa isithuba kwimarike yaseTianjin kwiimveliso ezinjalo xa isetyenziswa kwaye inokunciphisa ngokubonakalayo ixesha elikhokelayo lokuodola ubungakanani obukhulu, obutyebileyo obunodonga lwesakhiwo kunye nemibhobho exande.I-arc enecala eliphindwe kabini i-arc welding enkulu edityanisiweyo yombhobho ingasetyenziselwa ngokuthe ngqo ukuhanjiswa kweoli kunye negesi, umbhobho wensimbi we-JCOE usetyenziswe ngokubanzi kwiprojekthi yesizwe "ye-West-East gas transmission", ngelixa umbhobho wentsimbi yesakhiwo ungasetyenziswa ukwakhiwa kwe-ultra-high-rise steel structure, ngaphezu kokusetyenziswa kwenkqubo "yokujikeleza ukuya kwisikwere" inokucutshungulwa ibe yi-diameter oversized Ukongeza, inkqubo "yokujikeleza ukuya kwisikwere" inokuqhutyelwa kwi-oversized, i-ultra-thick-walled. imibhobho yentsimbi yoxande, enokusetyenziswa kwiindawo ezinkulu zokonwabisa kunye noomatshini abanzima kunye nokuveliswa kwezixhobo.
