Ukusukela ngeminyaka yoo-1930s, kunye nophuhliso olukhawulezayo lomgangatho ophezulu wemveliso eqhubekayo yokuqengqeleka kunye nokuqhubela phambili kwetekhnoloji yokuwelda kunye nokuhlola, umgangatho we-welds uye waphuculwa ngokuqhubekayo, kwaye iindidi kunye neenkcukacha zemibhobho yentsimbi edityanisiweyo iye yanda.Thunga umbhobho wentsimbi.Imibhobho yentsimbi edityanisiweyo yahlulwe yaba yimibhobho edityanisiweyo ethe tye kunye nemibhobho edityanisiweyo eshukumayo ngokohlobo lweewelds.Ukuhlelwa ngokwendlela yokuvelisa: inkqubo yokuhlelwa-i-arc edityanisiweyo yombhobho, umbhobho odibeneyo wokuxhathisa, (i-frequency ephezulu, i-frequency ephantsi) i-gas welded pipe, i-furnace welded pipe.
Imibhobho edityanisiweyo enedayamitha emincinci idityaniswa ngomthungo othe tye, ngelixa imibhobho edityanisiweyo enkulu idityaniswe ubukhulu becala.Ngokwemilo yesiphelo sombhobho wensimbi, ihlulwe ibe ngumbhobho odibeneyo ojikelezileyo kunye ne-special-shaped (isikwere, uxande, njl. njl.) umbhobho odibeneyo;ngokwezixhobo ezahlukeneyo kunye nokusetyenziswa, yahlulwe kulwelo lwezimayini Ukuhambisa imibhobho yentsimbi edityanisiweyo, imibhobho yentsimbi evundisiweyo yokuhambisa ulwelo oluphantsi koxinzelelo, imibhobho yentsimbi edityanisiweyo yokuhambisa ibhanti, njl. , hlela ngokwedayamitha yangaphandle * ubukhulu bodonga ukusuka kwincinci ukuya enkulu.
Izinto ezisetyenziswa ngokuqhelekileyo kwimibhobho edityanisiweyo zezi: Q235A, Q235C, Q235B, 16Mn, 20 #, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Nir19Nir1Cr11, etc.
Izikhewu ezisetyenziselwa imibhobho yentsimbi edityanisiweyo ziipleyiti zentsimbi okanye iintsimbi zentsimbi, ezahlulwe zibe yimibhobho edityanisiweyo yesithando somlilo, imibhobho edityanisiweyo yombane (i-resistance welded) imibhobho kunye nemibhobho edityanisiweyo ye-arc ezenzekelayo ngenxa yeenkqubo zabo ezahlukeneyo zokudibanisa.Ngenxa yeefom zayo ezahlukeneyo ze-welding, zinokwahlulwa zibe ziindidi ezimbini:
Umbhobho odityanisiweyo othe ngqo kunye nombhobho odityanisiweyo ojikelezayo.Ngenxa yobume bayo bokuphela, ihlulwe ibe ngumbhobho odibeneyo ojikelezileyo kunye ne-special-shaped (i-square, flat, njl.) ipayipi edibeneyo.Imibhobho edityanisiweyo yohlulwe ngokwezi ntlobo zilandelayo ngenxa yezixhobo zabo ezahlukeneyo kunye nokusetyenziswa:
I-GB/T3091-2008 (Iipayipi zensimbi ezidibeneyo zokuthutha umbane ophantsi): Isetyenziselwa kakhulu ukuthutha amanzi, igesi, umoya, ioli, ukufudumeza amanzi okanye umphunga kunye nezinye ngokubanzi eziphantsi koxinzelelo kunye nezinye iinjongo.Izinto zayo ezimele: Q235A ibakala lentsimbi.
I-GB/T14291-2006 (I-Welded Steel Pipe ye-Mining Fluid Transport): Isetyenziswa ikakhulu kwimibhobho yentsimbi edityanisiweyo ethe tye yoxinzelelo lomoya lomgodi, i-drain, kunye ne-shaft discharge gas.Izinto zayo ezimeleyo yi-Q235A, iBakala B intsimbi.
I-GB/T12770-2002 (Insimbi engenasici edityanisiweyo yombhobho yentsimbi yesakhiwo soomatshini): Isetyenziselwa ikakhulu oomatshini, iimoto, iibhayisekile, ifenitshala, ihotele kunye nomhombiso wokutyela kunye nezinye iinxalenye zoomatshini kunye nezakhiwo.Izixhobo zayo ezimele ziyi-0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, njl.
I-GB/T12771-1991 (Insimbi engenasici edityanisiweyo yombhobho yokuthuthwa kwamanzi): Isetyenziselwa kakhulu ukuthutha i-media media corrosive.Izinto ezimeleyo zi-0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, njl.
Ukongeza, imibhobho edityanisiweyo yentsimbi yokuhombisa (GB/T 18705-2002), imibhobho edityanisiweyo yentsimbi yokuhombisa yezakhiwo (JG/T 3030-1995), kunye nemibhobho yentsimbi edityanisiweyo yokutshintsha ubushushu (YB4103-2000).
Umbhobho odibeneyo we-Longitudinal unenkqubo elula yokuvelisa, ukusebenza kakuhle kwemveliso, ixabiso eliphantsi kunye nophuhliso olukhawulezayo.Ukomelela kwemibhobho edityanisiweyo ye-spiral idla ngokuba phezulu kunemibhobho edityanisiweyo ethe tye.Indawo engenanto ecutheneyo ingasetyenziselwa ukuvelisa imibhobho edityanisiweyo enedayamitha ezinkulu zombhobho, kwaye ibhilithi enobubanzi obufanayo ingasetyenziselwa ukuvelisa imibhobho edityanisiweyo enedamitha ezahlukeneyo zemibhobho.Kodwa xa kuthelekiswa nombhobho ochanekileyo wobude obufanayo, ubude be-weld bunyuswe ngo-30-100%, kwaye isantya sokuvelisa siphantsi.
Imibhobho edityanisiweyo enkulu okanye eshinyeneyo yenziwa ngokuthe ngqo kwizikhewu zentsimbi, ngelixa imibhobho edityanisiweyo emincinci kunye nemibhobho edityanisiweyo edityanisiweyo kufuneka idityaniswe ngokuthe ngqo ngemicu yentsimbi.Emva koko emva kokupholisha okulula, umzobo ulungile.
Isongezelelo: Umbhobho odityanisiweyo udityaniswe ngentsimbi yomtya, ngoko awukho phezulu njengombhobho ongenamthungo.
Iimveliso zisetyenziswa kakhulu kubunjineli bokubonelela ngamanzi, kwishishini lepetrochemical, ishishini lemichiza, ishishini lamandla, ukunkcenkceshela kwezolimo, kunye nokwakhiwa kwedolophu.Yenye yeemveliso ezingundoqo ezingama-20 eziphuhliswe kwilizwe lam.
Isetyenziselwa ukuthutha ulwelo: ukunikezelwa kwamanzi kunye nokukhupha amanzi.Isetyenziselwa ukuthutha igesi: igesi yamalahle, i-steam, i-liquefied petroleum gas.
Ngeenjongo zesakhiwo: njengemibhobho yokufumba kunye neebhulorho;imibhobho yeedokhi, iindlela, kunye nezakhiwo zokwakha.
