Dab tsi yog tshuaj lom neeg muaj pes tsawg leeg ntawm API 5L X80?
X80 NplE0 Pipeline Steel yog Asmeskas Petroleum Lub Koom Haum 'API spec 5L Pipeline Hlau Yeeb Nkab' hauv lub cim. x hauv API spec 5L tus qauv rau ntawm cov raj xa dej, 80 yog lub zog, nws chav yog cov kpsi, x80 uas cov nyiaj tau los ntawm 80kpsi pipeline hlau
X80 Steel Yeeb tau lees tias lub zog X80 Pipeline Steel Asmeskas me me ntawm 80, {}} psi (552mpa).
X80 Steel yeeb nkab tseem ceeb tshaj plaws X80 Pipeline Steel uas muaj zog, yog ib qho kev tiv thaiv zoo, thiab txhim kho kev ua haujlwm zoo li cas, thiab txhim kho cov nqi hluav taws xob qub, thiab txhim kho kev ua tau zoo ntawm lub qhov txhab nyiaj.
X80 Pipeline Hlau Siv Cov Qauv Siv: API spec 5l 5}} qauv, GB tus qauv, txhua qhov project cov qauv tshwj xeeb.
X80 NplE0 Pipeline Hlau Khoom Noj: Qhov tsuas yog muab rau hauv kub dov lossis siv cov xwm txheej qub.
X80 steel yeeb nkab tshuaj tshuaj pipeline pipeline pipeline tsom rau kev ua tau zoo, tsis muaj txoj cai tswj hwm ntawm cov tshuaj lom neeg muaj pes tsawg leeg.
Txij thaum pib ntawm 60 xyoo, nrog cov roj thiab roj pipeline kis kev kub siab thiab lub zog qis dua cov hlau (HSLA), tsuas yog kub lub xeev muab khoom siv.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm API 5L X80 yog raws li hauv qab no:
C: ≤ {0. 2%
Si: ≤ 0. 45%
MN: ≤1.85%
P: ≤ {0. 025%
S: ≤ {{0. 015% V: + NB + TI
V: + NB + TI: ≤ 0. 15
Cov lus qhia no ua kom cov x80 raj dej muaj lub zog siab thiab zoo weldability rau cov roj thiab roj pipeline cov ntawv thov.
