Imibhobho yentsimbi yekhabhoni enedayamitha enkulubhekisa ngokubanzi kwimibhobho yentsimbi yekhabhoni enobubanzi obungaphandle obungekho ngaphantsi kwe-200mm. Ezenziwe ngentsimbi yekhabhoni, zizinto eziphambili kumashishini kunye namacandelo asisiseko ngenxa yamandla azo aphezulu, ukuqina okuhle, kunye neempawu ezibalaseleyo ze-welding. I-Hot rolling kunye ne-spiral welding zidla ngokusetyenziswa kwimveliso yazo.Imibhobho yentsimbi eshushuzisetyenziswa ngokubanzi kwizicelo zoxinzelelo oluphezulu ngenxa yobukhulu bodonga obufanayo kunye nesakhiwo esixineneyo.

IiNgcaciso ezilungiselelweyo: Dibana neeMfuno ezahlukeneyo zeProjekthi

Iimpawu zemibhobho yentsimbi ye-carbon-diameter enkulu ichazwa yi-diameter yangaphandle, ubukhulu bodonga, ubude, kunye nebakala lezinto eziphathekayo. Iidayamitha zangaphandle ziqhele ukuqala ukusuka kwi-200 mm ukuya kwi-3000 mm. Ubukhulu obunjalo bubenza bakwazi ukuthutha ukuhamba kwamanzi amakhulu kunye nokubonelela ngenkxaso yesakhiwo, eyimfuneko kwiiprojekthi ezinkulu.

Umbhobho wentsimbi oshushu oshushu ugqamile ngenxa yeenzuzo zayo zenkqubo yokuvelisa: ukuqengqeleka kobushushu obuphezulu kuguqula iibhilidi zentsimbi zibe yimibhobho enobunzima obufanayo bodonga kunye nesakhiwo esixineneyo sangaphakathi. Unyamezelo lwedayamitha yangaphandle inokulawulwa ngaphakathi kwe ±0.5%, iyenze ilungele iiprojekthi ezineemfuno ezingqongqo, ezinjengemibhobho yomphunga kwiplanti ezinkulu zamandla obushushu kunye nothungelwano lokufudumeza olusezidolophini.

Q235 umbhobho wentsimbi yekhabhonikwayeUmbhobho wentsimbi ye-A36babe nemida ecacileyo ecacileyo yamabakala ahlukeneyo eemathiriyeli.

1.Q235 umbhobho wentsimbi: Umbhobho wensimbi we-Q235 ngumbhobho oqhelekileyo we-carbon structural steel e-China. Ngamandla esivuno angama-235 MPa, iveliswa ngokuqhelekileyo kubunzima bodonga lwe-8-20 mm kwaye isetyenziselwa ikakhulu ukuhanjiswa koxinzelelo oluphantsi, njengonikezelo lwamanzi lukamasipala kunye nokuhanjiswa kwamanzi, kunye nemibhobho yerhasi yeshishini ngokubanzi.

2.Umbhobho wentsimbi ye-A36: Umbhobho we-carbon steel we-A36 yinqanaba lentsimbi eliqhelekileyo kwiimarike zamazwe ngamazwe. Inamandla esivuno esiphezulu kancinci (250MPa) kunye ne-ductility engcono. Inguqulelo yayo yobubanzi obukhulu (edla ngokuba nobubanzi obungaphandle obuyi-500mm okanye ngaphezulu) isetyenziswa kakhulu ekuqokeleleni i-oyile nerhasi kunye nemibhobho yothutho, efuna ukumelana noxinzelelo oluthile kunye nokuguquguquka kobushushu.

Ukusetyenziswa koMbhobho wentsimbi weDiameter oMkhulu weCarbon

Umbhobho we-carbon steel we-diameter enkulu, kunye neenzuzo zayo zamandla aphezulu, ukumelana noxinzelelo oluphezulu, i-welding elula, kunye nokusebenza kweendleko, inezicelo ezingenakubuyiselwa kumacandelo amaninzi abalulekileyo. Ezi zicelo zinokuhlulwa zibe ziindawo ezintathu ezingundoqo: ukuhanjiswa kwamandla, ubunjineli beziseko ezingundoqo, kunye nemveliso yemizi-mveliso.

Ukuhanjiswa kwamandla: Isebenza njenge "aorta" yeoyile, igesi, kunye nokuhanjiswa kwamandla. Imibhobho ye-oyile nerhasi enqumla imimandla (efana noMbhobho weGesi yeNdalo kuMbindi weAsia kunye noMbhobho werhasi wasekhaya okwiNtshona-Mpuma) isebenzisa umbhobho wentsimbi wekhabhoni onobubanzi obukhulu (ubukhulu becala onobubanzi obungaphandle obuyi-800-1400mm).

Iziseko zophuhliso kunye nobunjineli bakamasipala: Ixhasa ukusebenza kwezixeko kunye nothungelwano lwezothutho. Kunikezelo lwamanzi lukamasipala kunye nokuhanjiswa kwamanzi, umbhobho wentsimbi wekhabhoni wobubanzi obukhulu (ububanzi obungaphandle obuyi-600-2000mm) lolona khetho lukhethwayo kwimibhobho yonikezelo lwamanzi engundoqo yasezidolophini kunye nemibhobho yokuhambisa amanzi esiphango ngenxa yokunganyangeki komhlwa (nobomi obudlula iminyaka engama-30 emva konyango lotyalo lokunqanda ukubola) kunye nesantya sokuhamba okuphezulu.

Imveliso yemizi-mveliso: Isebenza njengomqolo wemveliso enzima kunye nemveliso yeekhemikhali. Iiplanti zoomatshini abanzima zihlala zisebenzisa imibhobho yentsimbi yentsimbi enobubanzi obukhulu (15-30mm ubukhulu bodonga) kwizixhaso zikaloliwe wecrane kunye nezakhelo ezinkulu zesiseko sezixhobo. Umthamo wabo ophezulu wokuthwala umthwalo (umbhobho omnye unokumelana nemithwalo ethe nkqo edlula i-50kN) inceda ukuzinzisa ukusebenza kwezixhobo.

imibhobho yentsimbi yekhabhoni enobubanzi obukhulu

IiNdlela zeMarike kunye neNkalo yoShishino: Imfuno ekhulayo yeMibhobho yoMgangatho oPhezulu

Imfuno yemarike yemibhobho yentsimbi enobubanzi obukhulu yekhabhoni ikhula ngokuthe ngcembe ecaleni kweziseko ezingundoqo zehlabathi, amandla, kunye nophuhliso lwamashishini. Amacandelo emveli afana neekhemikhali zepetroli, ukuhanjiswa kombane, kunye nobonelelo lwamanzi ezidolophini kunye nokuhanjiswa kwamanzi ahlala engoyena nobangela wemfuno. Imfuno yemibhobho yentsimbi ye-carbon enobubanzi obukhulu iyaqhubeka nokukhula kushishino lwepetrochemical, kunye nemfuno yonyaka eqikelelwa ukuba ifikelele malunga ne-3.2 yezigidi zeetoni ngo-2030. Eli shishini lixhomekeke kwimibhobho yentsimbi ye-carbon-diameter enkulu ukuthutha i-oyile ekrwada, iimveliso ezisulungekileyo, kunye nezixhobo zekhemikhali ekrwada.
