Imiqathango yokuhanjiswa
Ngokuxhomekeke kwiimeko zonikezelo kunye nenqanaba lePSL, iX60 ingahlelwa ngolu hlobo lulandelayo:
PSL1: x60 okanye L415;
PSL2: X60N, X60Q, X60M okanye L415N, L415Q, L415M.
N: Ibonisa ukuqheleka kwezinto.Ngokufudumeza intsimbi kubushushu obuthile obulandelwa kukupholisa umoya.Ukuphucula i-microstructure kunye neepropati ze-mechanical zensimbi kunye nokwandisa ukuqina kwayo kunye nokuhambelana.
Q: Imele Ukucinywa nokuthomalalisa.Ukufudumeza intsimbi ngokuyifudumeza kwiqondo lobushushu elithile, ukuyipholisa ngokukhawuleza, emva koko uyifudumeze kubushushu obuphantsi.Ukufumana ibhalansi yeempawu ezithile zoomatshini, njengamandla aphezulu kunye nokuqina.
M: Ibonisa unyango lwe-thermo-mechanical.Idibaniso yonyango lobushushu kunye nomatshini wokuphucula i-microstructure kunye neempawu zentsimbi.Kunokwenzeka ukwandisa amandla kunye nokuqina kwentsimbi ngelixa ugcina iipropati ezintle ze-welding.
API 5L X60 Inkqubo yokuVelisa
Inkqubo yokwenziwa kwetyhubhu yentsimbi eyamkelekileyo yeX60
Ukuba ufumana ezi zishunqulelo kunzima ukuziqonda, jonga ukuhlanganiswa kwethu kwamanqakuizifinyezo eziqhelekileyo kwimibhobho yentsimbi.
Izinto eziluncedo ze-SAWL (LSAW)
Ukuba ufuna umbhobho wentsimbi wodonga olungqindilili olukhulu, ukhetho lokuqala luloSAWL (LSAW) umbhobho wensimbi.Umbhobho wensimbi we-LSAW unokuveliswa ngobukhulu ukuya kwi-1500mm ububanzi kunye ne-80mm kwindonga yodonga, ekwazi ngokupheleleyo ukuhlangabezana neemfuno zemibhobho yomgama omde kwiiprojekthi ezinkulu.
Ukongeza, ngexesha lenkqubo yokuvelisa, umbhobho wensimbi we-LSAW uthatha i-arc ye-arc enecala eliphindwe kabini (DSAW) inkqubo, eqinisekisa umgangatho we-weld seam.
I-API 5L X60 Ukwakhiwa kweMichiza
I-PSL1 ilula kakhulu kune-PSL2 ngokokwakheka kweekhemikhali, iimpawu zoomatshini, kunye nezinye iimfuno.
Oku kungenxaPSL1imele umgangatho osemgangathweni womgangatho wombhobho wentsimbi yombhobho, ngelixaPSL2inokubonwa njengoguqulelo oluphuculweyo lwe-PSL1, olunika ingcaciso engaphezulu kunye nolawulo olungqongqo lobulunga.
Ukuqulunqwa kweMichiza ye-PSL 1 Ipayipi ene-t ≤ 25.0 mm (0.984 in.)
Ukuqulunqwa kweMichiza ye-PSL 2 Ipayipi ene-t ≤ 25.0 mm (0.984 in.)
Kwiimveliso zemibhobho yentsimbi ye-PSL2 ehlalutywe ngeumxholo wekhabhoni ≤0.12%, icarbon elingana CEpcmingabalwa kusetyenziswa le fomula ilandelayo:
CEpcm= C + Si/30 + Mn/20 + Cu/20 + Ni/60 + Cr/20 + Mo/15 + V/15 + 5B
Kwiimveliso zemibhobho yentsimbi ye-PSL2 ehlalutywe ngeumxholo wekhabhoni > 0.12%, icarbon elingana CEllwingabalwa kusetyenziswa le fomula ingezantsi:
CEllw= C + Mn/6 + (Cr + Mo + V)/5 + (Ni +Cu)/15
Ukuma kweMichiza ene-t ＞ 25.0 mm (0.984 ngaphakathi.)
Iya kugqitywa ngothethwano kwaye iguqulwe ibe yinto efanelekileyo ngokusekwe kwiimfuno zemichiza engentla.
