Umbhobho weNtsimbi oDidiweyo okumgangatho ophezulu

Indawo engenanto esetyenziselwa umbhobho wentsimbi edibeneyo yintsimbi yentsimbi okanye intsimbi.Ngenxa yeenkqubo ezahlukeneyo zokudibanisa, ihlulwe ibe yipayipi ye-furnace welding, i-welding yombane (i-resistance welding) umbhobho kunye nombhobho odibeneyo we-arc.Ngenxa yeendlela ezahlukeneyo zokuwelda, zahlulwe zaba ngumbhobho odityanisiweyo othe ngqo kunye nombhobho odityanisiweyo.Ngenxa yokuma kwayo kokuphela, yahlulwe ibe yipayipi edityanisiweyo yesetyhula kunye nemilo ekhethekileyo (isikwere, isicaba, njl.njl.) umbhobho odityanisiweyo.Imibhobho edityanisiweyo yohlulwe ngokwezi ntlobo zilandelayo ngenxa yezixhobo zabo ezahlukeneyo kunye nokusetyenziswa:
I-GB / t3091-2008 (umbhobho wentsimbi odityanisiweyo wokuthuthwa koxinzelelo oluphantsi): isetyenziselwa ikakhulu ukuthutha amanzi, igesi, umoya, ioyile, ukufudumeza amanzi ashushu okanye umphunga kunye nolunye ulwelo oluphantsi loxinzelelo oluphantsi kunye nemibhobho kwezinye iinjongo.Izinto zayo ezimeleyo yi-Q235 ibakala lentsimbi.
I-GB / t14291-2006 (umbhobho wentsimbi odityanisiweyo wothutho lolwelo lwasezimayini): isetyenziswa ikakhulu kumthungo othe ngqo odityanisiweyo wentsimbi yombhobho woxinzelelo lomoya wasemgodini, umbhobho wokuhambisa amanzi kunye ne-shaft gas drainage.Izinto zayo ezimele ibakala le-Q235A kunye ne-B steel.
I-GB / t12770-2002 (umbhobho wentsimbi yensimbi engenasici kwisakhiwo soomatshini): ikakhulu isetyenziselwa oomatshini, iimoto, iibhayisekile, ifenitshala, ihotele kunye nomhombiso wokutyela kunye nezinye iinxalenye zoomatshini kunye neenxalenye zesakhiwo.Izinto ezimele ziyi-0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, 0cr18ni11nb, njl.
I-GB / t12771-1991 (insimbi engenasici edityanisiweyo yombhobho wokuthuthwa kwamanzi): isetyenziselwa kakhulu ukuthutha i-media media corrosive.Izixhobo ezimele ziyi-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 we-welded we-Longitudinal unenzuzo yenkqubo yokuvelisa elula, ukusebenza kakuhle kwemveliso, ixabiso eliphantsi kunye nophuhliso olukhawulezayo.Amandla ombhobho odityanisiweyo we-spiral uphezulu ngokubanzi kunombhobho odityanisiweyo othe ngqo.Inokuvelisa umbhobho odityanisiweyo onedayamitha yombhobho omkhulu ongenanto emxinwa, kunye nombhobho odityanisiweyo onedayamitha yombhobho ongenanto yobubanzi obufanayo.Nangona kunjalo, xa kuthelekiswa nombhobho womthungo othe tye kunye nobude obufanayo, ubude be-weld bunyuka nge-30 ~ 100%, kwaye isantya sokuvelisa siphantsi.Impahla ekrwada ukususwa - ukulinganisa - ukuphela kokucheba kunye ne-welding - i-looper - ukwenza - i-Welding - ukususwa kwe-weld yangaphakathi nangaphandle - ukulungiswa kwangaphambili - ukulungiswa kobushushu - ukulinganisa kunye nokulungiswa - uvavanyo lwangoku lwe-eddy - ukusika - ukuhlolwa kwe-hydraulic - Pickling - ukuhlolwa kokugqibela (ngokungqongqo ulawulo) - Ukupakishwa - ukuthunyelwa.Iimveliso zisetyenziswa kakhulu kubunjineli bamanzi ompompo, ishishini lepetrochemical, ishishini lemichiza, ishishini lamandla ombane, ukunkcenkceshela kwezolimo kunye nokwakhiwa kwedolophu.Yenye yeemveliso ezingundoqo ezingama-20 eziphuhliswe eTshayina.
