L360 txhais li cas
L360 yog ib kab -cov yeeb nkab qib tsim siv nyob rau hauv ISO 3183 thiab Suav tus qauv GB/T 9711. L stands rau kab yeeb nkab thiab 360 yog qhov tsawg kawg nkaus yield zog nyob rau hauv megapascals. Tib qib hauv API 5L yog xaiv X52, thiab ob lub npe xa mus rau cov khoom siv tib yam: ib kab - cov yeeb nkab steel nrog qhov muaj zog tsawg kawg nkaus ntawm 52,000 psi, sib npaug 360 MPa, thiab lub zog tensile yam tsawg kawg nkaus ntawm 460 MPa (66,700 psi). Cov qib yog siv rau cov roj thiab roj sib sau ua ke thiab cov kab sib kis thiab muaj nyob rau ntawm PSL1 thiab PSL2 specification qib.
L-Series thiab X-Series sib npaug
Lub L-series thiab X-series yog ob lub npe kev cai rau tib qib. Lub npe X muab qhov tsawg kawg nkaus tawm lub zog hauv ksi: X42, X46, X52, X60, X65, X70, thiab X80. Lub npe L muab tib tus nqi hauv megapascals: L290, L320, L360, L415, L450, L485, thiab L555. Yog li L360 yog X52, L415 yog X60, thiab L485 yog X70. Thaum ib qhov project hais txog ISO 3183 lossis GB / T 9711, cov npe L raug siv; Thaum nws hais txog API 5L, cov npe X tau siv, thiab kev hloov pauv yog qhov teeb meem ntawm chav nyob, tsis yog hloov khoom siv.
PSL1 thiab PSL2
L360 yog muab los ntawm ob theem khoom specification. PSL1 teeb tsa qhov tsawg kawg nkaus lub zog thiab cov chemistry yooj yim rau kev pabcuam dav dav. PSL2 ntxiv kev txwv lub zog siab tshaj plaws, qhov siab tshaj plaws tawm los- rau- qhov sib piv tensile, yuav tsum tau kuaj Charpy cuam tshuam rau ntau qhov ntau thiab tsawg, nruj dua phosphorus thiab sulfur txwv, thiab siab tshaj carbon sib npaug rau weldability, thiab PSL2 steels raug tua thiab nplua nplej. Rau kev xa cov pa roj, qis - qhov kev pabcuam kub, thiab ib puag ncig qaub, PSL2 nrog cov kev xav tau ntxiv uas tsim nyog yog qhov kev qhia ib txwm muaj.
Daim ntawv thov
L360 (X52) yog siv rau onshore thiab offshore roj thiab roj sib sau ua ke thiab xa cov kab, cov kav dej, thiab cov kab dej thiab slurry ntawm nruab nrab mus rau siab. Nws yog qhov kev xaiv pheej yig rau ntau lub cev kab uas tus qauv tsim tsis xav tau lub zog siab dua ntawm X60 lossis X70, thiab nws tau tsim seamless, los ntawm ERW, los ntawm LSAW, thiab los ntawm SSAW los npog tag nrho txoj kab uas hla. Phab ntsa tuab rau lub siab muab qis dua rau Qib B lossis X42, uas yog vim li cas qib tau teev tseg.
L360 vs Lwm Cov Yeeb Nkab Qib
Hauv cov pa roj carbon steel yeeb nkab tsev neeg, L360 / X52 zaum saum cov qib dav dav: API 5L Qib B thiab A106 Qib B ob leeg muaj qhov tsawg kawg nkaus ntawm 35,000 psi (240 MPa), thiab X42 nce qhov no mus rau 42,000 psi (290 MPa). X52 ntxiv cov kauj ruam tom ntej mus rau 52,000 psi (360 MPa), thiab X60 thiab siab dua yog siv rau siab - kev sib kis. Qhov kev xaiv yog kev txiav txim siab tsim raws li qhov siab, txoj kab uas hla, thiab phab ntsa{19}}thickness kev lag luam, nrog cov qib siab dua siv micro- alloyed HSLA steels rau lub zog thiab weldability.
Cov lus nug nquag
Q: L360 yeeb nkab yog dab tsi?
Ib kab -qib yeeb nkab rau ISO 3183 thiab GB / T 9711 nrog qhov tsawg kawg nkaus tawm lub zog ntawm 360 MPa, sib npaug rau API 5L X52.
Q: Puas yog L360 zoo ib yam li X52?
Yog lawm. L360 yog tus qauv ISO/GB thiab X52 yog tus qauv API ntawm tib qib, nrog rau lub zog tawm los qhia hauv MPa thiab ksi feem.
Q: Lub zog tensile ntawm L360 yog dab tsi?
Qhov tsawg kawg nkaus tensile lub zog yog 460 MPa (66,700 psi).
Q: Qhov txawv ntawm PSL1 thiab PSL2 yog dab tsi?
PSL2 ntxiv cov kev txwv lub zog siab tshaj plaws, tawm los- rau- kev tswj qhov sib npaug tensile, yuav tsum muaj kev ntsuam xyuas kev cuam tshuam, kev sib tw nruj dua, thiab cov pa roj carbon- sib npaug.
Q: L360 siv rau dab tsi?
Cov roj thiab roj sib sau ua ke thiab cov kab sib txuas, cov khoom siv, thiab cov kev pabcuam dej thiab slurry ntawm nruab nrab mus rau siab.
Q: L360 piv nrog Qib B li cas?
L360 muaj qhov tsawg dua qhov ua tau zoo zog (360 MPa tiv thaiv 240 MPa rau Qib B), tso cai rau cov phab ntsa nyias nyias rau tib lub siab.
