Iimeko zokuhanjiswa
Ngokuxhomekeke kwiimeko zokuhanjiswa kunye nenqanaba lePSL, iX60 ingahlulwahlulwa ngolu hlobo lulandelayo:
I-PSL1: x60 okanye i-L415;
I-PSL2: X60N, X60Q, X60M okanye L415N, L415Q, L415M.
N: Ibonisa ukulungelelaniswa kwezinto. Ngokufudumeza intsimbi ukuya kubushushu obuthile kulandele ukupholisa umoya. Ukuphucula ulwakhiwo lwentsimbi kunye neempawu zoomatshini kunye nokwandisa ukuqina kwayo kunye nokuhambelana kwayo.
Q: Imele ukucima kunye nokulungisa. Ukulungisa intsimbi ngokuyifudumeza kubushushu obuthile, uyipholise ngokukhawuleza, uze uyifudumeze kwakhona kubushushu obuphantsi. Ukuze ufumane ibhalansi yeempawu ezithile zoomatshini, ezinje ngamandla aphezulu kunye nokuqina.
M: Ibonisa unyango lwe-thermo-mechanical. Indibaniselwano yonyango lobushushu kunye nomatshini wokulungisa ulwakhiwo lwe-micro kunye neempawu zentsimbi. Kunokwenzeka ukonyusa amandla kunye nokuqina kwentsimbi ngelixa ugcina iimpawu ezilungileyo zokuwelda.

Iingenelo ze-SAWL (LSAW)
Ukuba ufuna umbhobho wentsimbi wodonga ongqindilili omkhulu, ukhetho lokuqala loluI-SAWL (I-LSAW) umbhobho wentsimbi. Umbhobho wentsimbi we-LSAW unokwenziwa ngobukhulu obufikelela kwi-1500mm ububanzi kunye ne-80mm ubukhulu bodonga, obukwaziyo ngokupheleleyo ukuhlangabezana neemfuno zemibhobho emide kwiiprojekthi ezinkulu.
Ukongeza, ngexesha lenkqubo yemveliso, umbhobho wentsimbi we-LSAW usebenzisa i-arc welding engaphantsi kwamanzi emacaleni amabini (I-DSAW) inkqubo, eqinisekisa umgangatho womthungo we-weld.
I-API 5L X60 Chemical Composition
I-PSL1 ilula kakhulu kune-PSL2 ngokwemilo yeekhemikhali, iimpawu zoomatshini, kunye nezinye iimfuno.
Oku kungenxa yokubaI-PSL1imele umgangatho oqhelekileyo womgangatho wombhobho wentsimbi yepayipi, ngelixaI-PSL2inokubonwa njengenguqulelo ephuculweyo yePSL1, enika iinkcukacha eziphucukileyo kunye nolawulo olungqongqo lomgangatho.
Ulwakhiwo lweeKhemikhali zePSL 1 Pipe ene-t ≤ 25.0 mm (0.984 in.)

Kwiimveliso zepayipi yentsimbi yePSL2 ezihlalutyiweyo ngeumxholo wekhabhoni we ≤0.12%, i-CE elingana nekhabhonii-pcmingabalwa kusetyenziswa le fomyula ilandelayo:
CEi-pcm= C + Si/30 + Mn/20 + Cu/20 + Ni/60 + Cr/20 + Mo/15 + V/15 + 5B
Kwiimveliso zepayipi yentsimbi yePSL2 ezihlalutyiweyo ngeumxholo wekhabhoni > 0.12%, i-CE elingana nekhabhonillwingabalwa kusetyenziswa le fomyula ingezantsi:
CEllw= C + Mn/6 + (Cr + Mo + V)/5 + (Ni +Cu)/15
Ulwakhiwo lweeKhemikhali olune-t ＞ 25.0 mm (0.984 in.)
Kuya kugqitywa ngokuxoxisana kwaye kulungiswe kwisakhelo esifanelekileyo ngokusekelwe kwiimfuno zesakhelo seekhemikhali ezingentla.
