Ingcaciso:umbhobho wentsimbi wobushushu obuphantsiiphakathicarbon yesakhiwo intsimbi. Imibhobho yentsimbi ebandayo kwaye eshushu kwaye ephantsi inokusebenza kakuhle, iipropathi ezilungileyo zemishini, ixabiso eliphantsi kunye nemithombo ebanzi, ngoko ke isetyenziswa ngokubanzi. Ubuthathaka bayo obukhulu kukuba ii-workpieces ezinobunzima obuphantsi, ubukhulu becandelo elikhulu kunye neemfuno eziphezulu akufanele zisetyenziswe.
Iumbhobho wentsimbi ongenamthungo ophantsiinokusebenza kwindawo ebanda kakhulu - 45~- 110 ℃. Inzuzo ebalaseleyo yombhobho wensimbi ongenamthungo ophantsi wobushushu kukuba unokusebenza kwindawo ephantsi kakhulu, engenakulinganiswa nombhobho wensimbi oqhelekileyo ongenamthungo. Umbhobho wensimbi ongenamthungo ophantsi-ubushushu obuphantsi unamandla amahle kunye nobushushu obuphantsi, kwaye usetyenziswa ngokubanzi ekwenzeni izixhobo zobushushu obuphantsi kwi-petroleum, imichiza, isichumisi kunye namanye amashishini anobushushu obusebenzayo - 45 ~ - 110 ℃. Ngophuhliso lwamashishini afanelekileyo, iimfuno zezinto eziphathekayo azikhawulelwanga kuphela kwiimfuno ezisisiseko ezifana nezakhiwo zomatshini kunye neempawu ze-welding, kodwa kunye neemfuno ze-H2S ukuxhathisa ukubola kwemibhobho yobushushu obuphantsi.
Umbhobho wentsimbi ongenamthungo osezantsiiyasebenza kubunjineli bemibhobho kwindawo yobushushu obuphantsi. Kukho iinkqubo ezimbini: umzobo obandayo kunye nokuqengqeleka okushushu. Ngokombono woyilo lwensimbi, i-steelmaking, i-rolling, unyango lobushushu kunye nezinye iinkqubo ze-low-temperature seamless pipe pipe kufuneka ilawulwe ngokungqongqo ukuze kuqinisekiswe ukuba umbhobho wensimbi ongenamthungo ophantsi unamandla, ukuqina kunye nokumelana nokugqwala. Kwiimfuno zobugcisa zombhobho wensimbi ongenamthungo ophantsi, umbutho wokuvelisa kunye neendleko zokuvelisa umbhobho wensimbi kufuneka uqwalaselwe ngokubanzi. Uyilo lokwakheka kombhobho wensimbi ongenamthungo ophantsi wobushushu kufuneka kuqinisekiswe ukuba imveliso inamandla afanelekileyo, ukuqina okuphantsi kobushushu obuphantsi, kunye nenkqubo yokunyanga ubushushu obufanelekileyo Ukuqina okuhle kunye nokuchasana nokuqhekeka kwe-hydrogen.
Umgangatho olawulayo wombhobho wensimbi ongenamthungo ophantsiI-ASTM A333-Imibhobho yentsimbi engenamthungo kunye neWelded kwiNkonzo yoBubushushu obuphantsi
Izinto eziphathekayo zobushushu obuphantsiumbhobho wentsimbi ongenamthungoiimveliso: 16Mn, 10MnDG, 09DG, 09Mn2VDG, 06Ni3MoDG, njl.
