Imibhobho edityanisiweyo yentsimbi yekhabhoni ubukhulu becala zahlulwe zibe ziinkqubo ezintathu: ukuwelda kombane (i-RW), i-spiral submerged arc welding (SSAW) kunye ne-straight seam submerged arc welding (LSAW). Iibhobho ze-carbon steel welded eziveliswa zezi nkqubo zintathu zinendawo yazo kwindawo yesicelo ngenxa yezinto ezihlukeneyo, iinkqubo zokwenza, ubungakanani becaliber kunye nomgangatho.

1. Umthungo othe tye odityaniswe ngumbhobho odityanisiweyo wokumelana nombane (ERW)

Ukuxhathisa kombane umbhobho odityanisiweyo lolona hlobo lokuqala lombhobho wentsimbi oveliswe kwilizwe lam, kunye noluhlu olubanzi lwezicelo, elona nani likhulu leeyunithi zemveliso (ngaphezu kwama-2,000), kunye nemveliso ephezulu (ibali malunga ne-80% yomthamo wemveliso iyonke. wemibhobho edityanisiweyo). Ubalulo lwemveliso yi Ф20 ~ 610mm. idlale indima ebalulekileyo. Ukusukela ngeminyaka yoo-1980, malunga neeseti ezingama-30 zeeyunithi ze-ERW219-610mm zithengwe kumazwe angaphandle. Emva kweminyaka yokuziqhelanisa nemveliso, inqanaba letekhnoloji yezixhobo lenze inkqubela phambili enkulu, kwaye umgangatho wemveliso nawo uhlala uphucuka. Ngenxa yotyalo-mali oluphantsi, umphumo okhawulezayo kunye noluhlu olubanzi lwesicelo, luphuhliswe ngokukhawuleza. Ngophuhliso lwenkqubo yokuvelisa ipleyiti CSP, ibonelela ngexabiso eliphantsi, izinto ezithembekileyo ezisemgangathweni ekrwada, kwaye kudala iimeko ezilungileyo uphuhliso yayo ngakumbi kwixesha elizayo. Le nxalenye yeemveliso iphuhliswe ukusuka kwintsimi yothutho lwamanzi kunye nesakhiwo ukuya kumbhobho we-oyile kunye nombhobho womgca kwintsimi yokusetyenziswa kombhobho ongenamthungo.

2. Umbhobho odityanisiweyo we-arc odityanisiweyo (SSAW)

Utyalo-mali lwezixhobo zombhobho odityanisiweyo we-arc we-spiral uphantsi, kuba ukusetyenziswa kwe-coil coil coil coil welding ukuvelisa umbhobho odityanisiweyo omkhulu (Ф1016 ~ 3200mm), inkqubo yokuvelisa ilula, iindleko zokusebenza. iphantsi, kwaye inenzuzo yokusebenza ngexabiso eliphantsi. ilizwe lam oyile kunye negesi transmission spiral welded umbhobho wenze ifomathi esisiseko ikakhulu isekelwe kumbhobho wentsimbi edityaniswe nenkqubo yepetroleum. Ukwamkela ubugcisa obuphambili obunjengokwenza uxinzelelo olusezantsi lwentsalela kunye nokuphela kombhobho ukwandiswa komatshini, umgangatho wombhobho odityanisiweyo we-spiral oye waphantsi kolawulo olungqongqo lomgangatho unokuthelekiswa nalowo wombhobho odityanisiweyo othe tye. Lolona hlobo lombhobho olusetyenziswayo kwilizwe lam kumgama omde weprojekthi yemibhobho yerhasi. Umthamo wayo wemveliso ukwazile ukuhlangabezana neemfuno zokwakhiwa kwemibhobho ye-oyile nerhasi imigama emide yelizwe lam, kwaye ithunyelwe kumazwe angaphandle ngobuninzi.

3. Umthungo othe tye ontywiliselwe umbhobho we-arc odityanisiweyo (LSAW)

I-Longitudinal submerged arc welding bubuchwephesha bokwenza umbhobho obuphambili obuphuhliswe kade kwilizwe lam, kwaye itekhnoloji ye-UOE yayisetyenziswa kakhulu ngaphambili. Kwiminyaka yakutshanje, inkqubela phambili ye-JCOE ngokuthe ngcembe ibe yenye itekhnoloji entsha yesiqhelo kwilizwe lam nakwihlabathi. Imibhobho ye-arc edityanisiweyo ye-arc emide ikumgangatho othembekileyo kwaye isetyenziswa ngokubanzi kwimigca ye-oyile yoxinzelelo oluphezulu kunye negesi yothutho. Ngenxa yotyalo-mali oluthe kratya lwale yunithi yombhobho odityanisiweyo, izinto ezisetyenziswayo ziipleyiti ezibanzi nezityebileyo ezinexabiso eliphezulu, inkqubo inzima, ukusebenza kakuhle kwemveliso kuphantsi, kwaye ixabiso lemveliso liphezulu.
