L360 pombi simbi tsika yekugadzirisa pombi yekufambisa pombi
L360 Pipeline Steel, Chinangwa: API SPEC 5L-2011 (Pipeline Specification), yakagadzirwa uye yakadhindwa neAmerican Petroleum Institute, inoshandiswa pasi rose.Pipepipe: Kutakura mafuta, gasi kana mvura kubva pasi nepombi kuenda kuindasitiri yemafuta negasi.Pipeline pombi rinosanganisira musono uye welded pombi marudzi maviri, pombi magumo ane sandara magumo, threaded magumo uye socket kuguma;Iyo yekubatanidza modhi ndeye kupera welding, hoop yekubatanidza, socket yekubatanidza uye zvichingodaro.Chinhu chikuru chechubhu B, X42, X46, X56, X65, X70 uye imwe giredhi resimbi.Kambani yedu yakapasa API certification (API 5CT uye API 5L) muna Nyamavhuvhu 2009.
L360 Pipeline Steel, API SPEC 5L GB/T9711.1 GB/T9711.2 China National Standard Application: Oxygen, mvura nemafuta ekuendesa mapaipi mumafuta negasi indasitiri B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485
Nekuvandudzwa kwepombi simbi ndiro tekinoroji uye kufambira mberi kwe welded pombi kuumba, welding tekinoroji, kushandiswa kwepombi ine welded pombi mukuwedzera zvishoma nezvishoma, kunyanya mune yakakura dhayamita welded pombi kirasi scope zvakanakira zvinooneka, uye mutengo zvinhu, welded pombi yave yakanyanya mumunda wemutsetse wepombi, iyo inomisa kugadzirwa kwesimbi isina musono pombi yesimbi.Muna 2004, kubuda kwepombi isina musono ingangoita 400,000 t, giredhi resimbi rinosanganisira X42-70, uye marudzi acho ari pamahombekombe pombi uye pombi yepasi pemvura.
Kugadzirwa kwepombi yesimbi yakakwira giredhi pombi inotora microalloying yekudziya kupisa maitiro, mutengo wekugadzira wesimbi isina musono pombi uripachena wakakwira kupfuura welded pombi, uye nekuvandudzwa kwegiredhi resimbi, senge X80 uye pamusoro pesimbi giredhi pombi pombi muganho pane kabhoni yakaenzana. , iyo yakajairika nzira yepombi isina musono yakaoma kuzadzisa zvinodiwa nevashandisi;Imwe neimwe 12Cr1moV alloy pombi inogadzira iri kuita basa rekutsvagisa kwesainzi kuitira kuvandudza kushorwa kwepombi yayo yepombi uye kushanda kwakagadzikana munzvimbo yakaderera uye yakakwira tembiricha.
