API 5L X52 Seamless PSL1 / PSL2 Yeeb Nkab Specification

API5L X52 seamless steel yeeb nkab yog lub siab - lub zog kav dej tshwj xeeb uas tsim los rau kev lag luam roj thiab roj, nrog rau qhov tsawg kawg nkaus lub zog ntawm 52ksi. API5L X52 muaj ob qib tseem ceeb: PSL1 thiab PSL2 tau teev tseg los ntawm API 5L tus qauv ntawm American Petroleum Institute.

Khoom Taw qhia

API 5L yog tus qauv rau seamless thiab welded steel kav siv nyob rau hauv roj thiab roj kev lag luam pipelines tsim los ntawm American Petroleum Institute. X52 seamless steel yeeb nkab yog siab - lub zog steel yeeb nkab dav siv hauv kev lag luam roj thiab roj. Nws yog qib siab ntawm cov hlau ntau dua li X42, nrog cov khoom muaj zog zoo dua thiab tsim nyog rau kev siv siab dua.
Qhov "X" hauv X52 sawv cev rau cov raj xa dej, thiab "52" txhais tau hais tias qhov tsawg kawg nkaus lub zog ntawm cov hlau yog 52 ksi (txog 360 MPa).
API 5L X52 carbon steel yeeb nkab feem ntau yog ua los ntawm cov hlau, uas muaj qee cov pa roj carbon (C), manganese (Mn), phosphorus (P), sulfur (S) thiab lwm yam ntsiab lus, thiab kuj tseem muaj cov chromium (Cr), nickel (Ni), tooj liab (Cu), molybdenum (Mo) thiab lwm yam alloying ntsiab.
API 5L X52 yeeb nkab yog cov yeeb nkab uas siv dav hauv kev lag luam roj thiab roj, siv los thauj cov roj av thiab cov pa roj carbon monoxide los ntawm lub taub hau mus rau qhov chaw refinery, cov chaw tsim khoom lossis chaw cia khoom, thiab lwm yam.

 

Dab tsi yog qhov txawv ntawm API 5L X52 PSL-1 thiab PSL-2?

API 5L X52 muaj ob yam khoom tshwj xeeb, PSL-1 thiab PSL-2, nrog rau cov kev sib txawv hauv qab no:
Cov tshuaj muaj pes tsawg leeg: PSL-1 kuj xoob, nrog rau qhov siab tshaj plaws txwv ntawm cov ntsiab lus carbon; PSL-2 yog nruj, nruj me ntsis tswj impurities xws li sulfur thiab phosphorus los txhim kho lub purity thiab kev ua tau zoo stability ntawm hlau.
Cov khoom siv kho tshuab: PSL-1 muaj qhov xav tau qis thiab tsim nyog rau cov xwm txheej dav dav; PSL-2 yog siab dua, nrog zoo tensile thiab yield zog ntsuas, thiab muaj peev xwm tiv taus siab dua thiab load.
Tsis yog-kev kuaj kev puas tsuaj: PSL-1 yuav tsis muaj kev sim lossis xav tau kev sim yooj yim; PSL-2 yuav tsum tau kuaj ib los ntawm ib qho, siv ultrasound, X-rays, thiab lwm yam los xyuas qhov tsis xws luag.
Kev Tswjhwm Zoo: PSL-1 muaj kev tswj xyuas xoob thiab qee qhov kev tshuaj xyuas; PSL-2 muaj kev sib txuas nruj, thiab cov qauv siab tau ua raws li cov khoom siv raw mus rau cov khoom tiav kom ntseeg tau cov khoom zoo.
