Iityhubhu zentsimbi eziqinileyo zesakhiwo seMegaprojects zanamhlanje

Kuphuhliso lweziseko zophuhliso lwamazwe ngamazwe, ababoneleli ngeetyhubhu zentsimbi yesakhiwo sehlabathi bajongene neemfuno ezikhulayo zeeprofayili ezinkulu. Njengoko iiprojekthi ezinkulu ezifana nezakhiwo eziphakamileyo, izakhiwo zebala lemidlalo, kunye neziseko zomoya olwandle ziqhubeka zikhula, iindawo eziqhelekileyo zesikwere ezingenanto ezifana ne-400×400 mm okanye i-500×500 mm azisanele ukuhlangabezana neemfuno zesakhiwo. Kwiinjineli zesakhiwo ezikhupha iSicelo seNgqikelelo, ukuphucula i-cross-sectional modulus ngelixa kulawula ubunzima bentsimbi iyonke ngumceli mngeni ohlala uhleli. Xa ujongene nemithwalo enzima ye-axial kunye namaxesha anzima okugoba,umbhobho wesikwere obunzima bodonga olunzimakunye neendawo ezinkulu ezingenanto zibuxande (I-SHS/I-RHS) zibonelela ngokusebenza kakuhle kwesakhiwo okungenakuthelekiswa nanto xa kuthelekiswa nemiqadi evulekileyo eqhelekileyo okanye iipleyiti ezidityanisiweyo.

Imida yokudibanisa ngokwesiko kunye nokuveliswa kwemibhobho yentsimbi ye-LSAW

Xa uyilo lwesakhiwo oluqhelekileyo lufuna iindawo ezinkulu zesakhiwo ezingenanto ezidlula i-1000 mm, amasebe okuthenga ahlala enengxaki yokunqongophala kwemveliso. Kwimimandla emininzi yehlabathi, abakhi banyanzelwa ukuba badibanise ngesandla iipleyiti ezine zentsimbi nganye nganye kwiindawo zebhokisi ezakhiweyo kwindawo, okanye badibanise iityhubhu ezininzi ezincinci zibe zii-trusses ezintsonkothileyo. Olu hlobo lokwenziwa kwesakhiwo lufuna ukudityaniswa kwentsimi enzima, ukwandisa iindleko zabasebenzi kunye nokwandisa iishedyuli zovavanyo ezingonakalisiyo. Ukongeza, ii-seams ze-weld zentsimi exineneyo zibeka umngcipheko wokudinwa kwexesha elide. Ngelixa ii-heavy-wall zinzima.I-LSAWUmbhobho wentsimbi uthembeke kakhulu ekudluliseleni ulwelo, ukuguqula iprofayili engqukuva enobukhulu obuphezulu ibe yityhubhu enkulu yesikwere kufuna amandla amakhulu emizi-mveliso azinikeleyo, anawo amashishini ambalwa kakhulu ehlabathini.

Ukwaphula Imida yoBukhulu ngeeCandelo eziSikwere eziMgobo eziyi-1550 x 1550 x 80 mm

Ukuze kuvalwe esi sikhewu sibalulekileyo sokubonelela, iYuantai Derun iphucule i-matrix yayo yokuvelisa iityhubhu zentsimbi enzima. IYuantai Derun idlule kwimida yeenkqubo zemveli zokwenza ubanda. Le nkampani ngoku inokuvelisa amacandelo angenanto anesikwere esinye ngobukhulu obufikelela kwi-1550 × 1550 mm kunye nobukhulu bodonga obufikelela kwi-80 mm. Ezi profayili ze-SHS kunye ne-RHS ezinkulu kakhulu zinika abathengi isisombululo esithembekileyo, esenziwe ngumzi-mveliso, sinciphisa imfuneko yokuwelda kwindawo kwaye senza ukufakwa kunye nokuphathwa kwezinto kube lula ngakumbi.

I-Engineering Logic: I-JCOE kunye neTekhnoloji ye-Round-to-Square

Ukuvelisa ngempumelelo umbhobho wesikwere wodonga obunzima obuyi-80 mm kufuna indlela entsha yokuvelisa.Yuantai DerunIyahlukana nokwakheka kwe-cold roll eqhelekileyo ngokudibanisa inkqubo yokwenza i-JCOE yepleyiti enzima kunye netekhnoloji ephucukileyo ye-Round-to-Square. Ipleyiti iqale icinezelwe inyathelo ngenyathelo ibe yiprofayili yesangqa esijikelezayo esinomthungo othe tye kusetyenziswa izixhobo ze-JCOE ezinetoni ephezulu kunye ne-Submerged Arc Welding enamacala amabini. Ityhubhu ejikelezileyo enobukhulu obuphezulu emva koko yenziwe inyathelo ngenyathelo ibe yimo yesikwere okanye yoxande kusetyenziswa i-roll-forming echanekileyo. Le nkqubo yokubumba kancinci inceda ukusasaza uxinzelelo ngokulinganayo kumbhobho, inciphisa umngcipheko wokuqhekeka kweekona kwaye iphephe ukuqhekeka emaphethelweni.

Uqinisekiso loMgangatho: Imigangatho kunye noQinisekiso

Kwiindawo ezinzima zesakhiwo ezisetyenziswa kwiinkqubo eziphambili zokuthwala umthwalo, ulawulo oluqinileyo lomgangatho kunye nokulandeleka ngokupheleleyo kwezinto kubalulekile. Emva kokwenziwa nokudityaniswa, icandelo ngalinye le-1550 mm lidlula kwinkqubo yonyango lobushushu olulawulwayo emva kokudityaniswa. Eli nyathelo linceda ekuphuculeni ulwakhiwo lwangaphakathi lwentsimbi kwaye lisuse uninzi loxinzelelo olushiyekileyo kwimveliso, liphucula uzinzo lobukhulu kunye nokunciphisa umngcipheko wokuqhekeka okubangelwa yi-hydrogen.

Inkqubo yemveliso ibandakanya uvavanyo lwe-ultrasonic oluzenzekelayo kunye novavanyo lwe-radiographic ukuze kuhlolwe ngokupheleleyo imithungo ye-weld. Le mibhobho ihlangabezana nomgangatho wamva nje we-GB/T 6728-2025 kwaye yenzelwe ukuhambelana namanqanaba aphesheya afana ne-EN 10210 S355J2H kunye ne-ASTM A500 Grade B/C, ukuqinisekisa amandla azinzileyo kunye nokusebenza kakuhle kwiimeko zobushushu obuphantsi. Ibhetshi nganye iza neSatifikethi soVavanyo lweMill kunye nokuqinisekiswa kwekhowudi ye-QR, okunika abathengi kunye namaqela obunjineli ukulandeleka okugcweleyo kunye nokuzithemba kumgangatho wemveliso kwiiprojekthi zesakhiwo ezifuna ukwenziwa.
