Tshuaj Muaj Tshuaj

API 5L PSL1 X52 Qhia meej cov hauv qab noTshuaj Ntau Tshaj Plaws Cov Ntsiab Lus(hnyav%):

Lub ntsiab	Siab tshaj (%)	Qhov tseem ceeb
Carbon (c)	0.28	Cuam tshuam lub zog thiab weldability. Ntau dua cov pa roj carbon ntau dua ua kom tawv tawv tab sis txo qib siab.
Manganese (mn)	1.40	Txhim kho lub zog thiab cov tawv nqaij tawv. Sib tw sib npaug thiab tawv.
Phosphorus (p)	0.030	Impurity; txo qis tawv thiab txhawb nqa brittleness.
Sulphur (s)	0.030	Impurity; Ua rau kub tawg tawg thaum vuam.
Silicon (si)	0.45	Deagidizer; Txhim kho lub zog thiab tiv taus oxidation.

Tsab ntawv: PSL1 tso cai me ntsis ntau dua kev txwv (xws li leej faj thiab phosphorus) piv rau PSL2, ua rau nws muaj txiaj ntsig ntau dua tab sis tsis tshua muaj txiaj ntsig hauv cov ntawv thov tseem ceeb.

Cov Khoom Siv Neeg Kho Tshuab

API 5L PSL1 X52 yuav tsum ua kom tau raws li cov neeg siv hauv qab no:

Ntiag tug	Tus Nqi Muaj Ntau	Qhov tseem ceeb
Yield zog (ys)	Ntau dua los yog sib npaug rau 52,200 psi (360 MPa)	Yam tsawg kawg nkaus lub zog yuav tsum tau tiv thaiv cov roj hmab zoo hauv qab siab.
Tensile lub zog (TS)	Ntau dua los yog sib npaug rau 66,700 psi (460 MPa)	Qhov kawg lub zog ua ntej ua tsis tiav. Ts / ys piv ua kom muaj peev xwm sib luag.
Elongation	Ntau dua los yog sib npaug rau 21% (rau 2- nti gauge ntev)	Kev ntsuas kev ntsuas; tseem ceeb rau kev sib sau thiab khoov cov kav dej.

Ntxiv Yuav Tsum Tau:

Kev nyuaj: Feem ntau tsawg dua los yog sib npaug rau 248 HV10 (vickers hardness) kom tsis txhob muaj hydrogen-inducts cracking.

Charpy cuam tshuam Kev Ntsuas: Tsis tas yuav tsum muaj rau PSL1 (yuav tsum tau rau PSL2).

Cov Ntawv Thov

API 5L PSL1 x52 kav dej yog qhov dav dav hauv cov ntawv thov hauv qab no:

Roj Thiab Roj Pipelines: Haum rau kev thauj cov roj, nkev, thiab lwm yam dej nyob rau hauv cov kev mob siab.

Dej Khoom Siv Lub Tshuab Dej: Siv hauv cov kav dej hauv nroog vim lawv corrosion tsis kam.

Offshore thiab Onshore tej yaam num: Zoo rau ob qho tib si onshore thiab offshore daim ntawv thov vim lawv lub zog thiab lub zog.

Cov ntawv thov txheej txheem: Siv hauv kev tsim kho thiab kev tsim kho uas muaj zog thiab kev cia siab yog qhov yuav tsum tau ua.

Qhov Zoo

Siab lub zog thiab kev ruaj khov: X52 Kav Pipes muab lub zog txaus rau cov ntawv thov kev siab siab thaum muaj kev tswj hwm zoo.

Nqi zog-ua hauj lwm: Piv rau cov qhab nia siab dua li X60 lossis X65, X52 tau muab cov tshuaj zoo tsis muaj txiaj ntsig ntawm kev ua tau zoo.

Zoo heev Weldability: Cov ntsiab lus carbon cov ntsiab lus thiab cov ntsiab lus alloy ua kom yooj yim ntawm vuam, uas yog qhov tseem ceeb rau kev tsim kho loj loj.

Corrosion Kuj: Cov sulfur thiab phosphorus qis thiab phosphorus cov ntsiab lus, nrog rau alloying ntsiab xws li chromium, txhim kho corrosion, txhim kho corrosion tsis kam.

Versatility: Haum rau ntau cov ntawv thov, suav nrog cov chaw muab kev pab qaub uas muaj cov txheej txheem ntxiv.

Kev sib piv nrog lwm qib

Teem nqi	Ys, min (psi)	Ts, Min (psi)	Cov Ntawv Qhia Tseem Ceeb	Qhov Zoo Tshaj X52	Txwv vs. X52
X42	42,100	60,200	Low-siab Pipelines, Cov Tshuab Dej	Tus nqi qis, yooj yim rau weld	Txo lub zog tsis pub muaj peev xwm
