API 5L GR.Bumbhobho wentsimbi engenamthungo yinto ephambili esetyenziswa ngokubanzi kwiinkqubo zemibhobho yeoli kunye negesi yendalo. Ineempawu ezigqwesileyo zoomatshini, ukuxhathisa ukubola kunye nokuthembeka, ngenxa yoko iye yathandwa luninzi lwabasebenzisi.
Ngezantsi, siya kwazisa iimpawu, indawo zesicelo kunye neenkqubo zokuvelisaAPI 5L GR.Bumbhobho wentsimbi engenamthungo ngokweenkcukacha. Iimpawu zeMveliso: ububanzi obungaphandle be-21.3mm ~ 762mm, ubukhulu bodonga 2.0 ~ 140mm Indlela yokuvelisa: i-hot rolling, umzobo obandayo, ukwandiswa okushushu, isimo sokuhanjiswa: ukuqengqeleka okushushu, unyango lobushushu.
Iimpawu zeAPI 5L GR.Bumbhobho wensimbi ongenamthungo 1. Amandla aphezulu: I-API 5L GR.B ipayipi yensimbi engenamthungo yenziwe nge-high-quality carbon structural steel, inamandla okuvelisa isivuno esiphezulu kunye namandla okunyamezela, kwaye inokumelana noxinzelelo olukhulu kunye nomthwalo. 2. Iplastiki efanelekileyo: Umbhobho wensimbi uneplastiki efanelekileyo kwiqondo lokushisa, kwaye unokucutshungulwa ngokulula ngokugoba, i-welding kunye neminye imisebenzi yokucubungula. 3. Ukumelana nokubola: I-API 5L GR.B ipayipi yensimbi engenamthungo iye yafumana unyango olukhethekileyo lokuchasana ne-corrosion, inokumelana ne-corrosion, kwaye inokumelana ngokufanelekileyo nokhukuliseko lweendaba ezahlukeneyo zokubola. 4. Ukuthembeka okuphezulu: Umbhobho wensimbi ulawulwa ngokungqongqo umgangatho ngexesha lenkqubo yokuvelisa ukuqinisekisa ukuba umbhobho ngamnye wensimbi uhlangabezana neemfuno eziqhelekileyo kwaye unokuthembeka okuphezulu kakhulu.
Iindawo zokusetyenziswa kwe-API 5L GR.B ipayipi yensimbi engenamthungoAPI 5L GR.Bumbhobho wentsimbi ongenamthungo usetyenziswa kakhulu kwiinkqubo zeoyile kunye negesi yendalo. Ngexesha lokuhlolwa kweoli, ukumbiwa kwemigodi, ukucutshungulwa kunye nokuthutha, umbhobho wensimbi unokumelana neendawo ezinzima ezifana nokushisa okuphezulu, uxinzelelo oluphezulu kunye nokugqwala ukuqinisekisa ukuthuthwa okukhuselekileyo nokuzinzileyo kweoli kunye negesi yendalo. Ukongeza, ikwasetyenziswa ngokubanzi kwiinkqubo zokuthutha ulwelo kwiikhemikhali, amandla ombane, ukugcinwa kwamanzi kunye namanye amashishini.
