Pombi yemutsetse: Inyaya yekutakura mafuta, gasi kana mvura inotorwa kubva pasi kuenda kumakambani emafuta negasi kuburikidza nepombi yetambo. Mapaipi etambo anosanganisira mapaipi asina musono uye akasungirirwa. Mapaipi acho akaenzana, mativi ane shinda uye magumo emasokisi; nzira dzekubatanidza ndedzekupinza, kubatana, kubatana kwemasokisi, nezvimwewo.

Pfupiso yepombi yemutsetse
Mashandisirwo: Inoshandiswa pakufambisa mafuta, gasi, mvura nemafuta muindasitiri yemafuta negasi

API SPEC 5L-2018(Kutsanangurwa kwepombi yemutsetse) inounganidzwa uye inoburitswa neAmerican Petroleum Institute uye inowanzoshandiswa pasi rese.

Zvichienderana nezvinodiwa zvakasiyana zvekushanda kweGB/T9711-2017mapaipi esimbi epaipi, tempering inogona kukamurwa kuita mhando dzinotevera zvichienderana netembiricha yetempering:
1. Kudziisa tembiricha yakaderera (150-250 degrees)
Chimiro chinowanikwa nekudziya tembiricha yakaderera imartensite yakapfava. Chinangwa chayo ndechekuderedza kushushikana kwemukati uye kuputsika kwesimbi yakapfava ukuwo ichichengetedza kuomarara kwakanyanya uye kuramba kupfeka kwakanyanya kwesimbi yakapfava, kuitira kudzivirira kutsemuka kana kukuvara nguva isati yakwana panguva yekushandiswa. Inonyanya kushandiswa pazvishandiso zvakasiyana-siyana zvekucheka zvine kabhoni yakawanda, maturusi ekuyera, mapaipi esimbi eGB/T9711, mabheringi anotenderera uye zvikamu zvekabhoni, nezvimwewo. Kuomarara mushure mekudziya kazhinji kunonzi HRC58-64.
2. Kupisa tembiricha iri pakati nepakati (250-500 degrees)
Chimiro chinowanikwa nekupisa tembiricha yepakati ndeche troostite inodziya. Chinangwa chayo ndechekuwana simba rekugadzira, muganho we elastic uye kusimba kwakanyanya. Saka, inonyanya kushandiswa pakurapa mapaipi akasiyana-siyana esimbi eGB/T9711 nemaforoma anopisa, uye kuomarara mushure mekudziya kunowanzova HRC35-50.
3. Kupisa tembiricha yepamusoro (500-650 degrees)
Chimiro chinowanikwa nekupisa kwakanyanya chinoshandiswa ne tempering troostite. Kurapa kupisa kunobatanidza quenching ne tempering tempering kunowanzonzi quenching ne tempering treatment, chinangwa chayo ndechekuwana hunhu hwakazara hwemakanika hune simba rakanaka, kuomarara, plasticity uye kuomarara. Saka, inoshandiswa zvakanyanya muzvikamu zvakakosha zvemaumbirwo emotokari, mapaipi esimbi eGB/T9711, maturusi emuchina, nezvimwewo, zvakaita sematanda ekubatanidza, mabhaudhi, magiya nemashaft. Kuomarara mushure me tempering kunowanzova HB200-330.
