Lub zog tawm ntawm API 5L L360 PSL2 piv rau lwm qib li cas?

Sib piv nrog cov qib qis:
API 5L L360 PSL2 muaj zog yield zog dua cov qib qis xws li X42 thiab X46. Qhov tsawg kawg nkaus yield zog ntawm X42 yog hais txog 290MPa, qhov tsawg kawg nkaus yield zog ntawm X46 yog hais txog 317MPa, thiab lub zog tawm los ntawm L360 PSL2 yog 360MPa - 510MPa. Nws lub zog muaj zog ntau dua tuaj yeem ua rau cov phab ntsa ntawm cov yeeb nkab nyias nyias thaum tswj qhov kev ntsuas siab, uas yog qhov tsim nyog los txo cov nqi khoom thiab qhov hnyav, thiab muaj txiaj ntsig zoo dua hauv qee cov nqi-rhiab roj thiab roj xa mus rau ceg kab lossis kev siv cov raj xa dej dav dav uas yuav tsum tau ua kom tsis muaj zog. siab heev.
Sib piv nrog cov qib siab dua:
Piv nrog rau cov qib siab dua xws li X60, X70 lossis X80, lub zog tawm ntawm L360 qib qis dua. Qhov tsawg kawg nkaus yield zog ntawm X60 yog hais txog 414MPa, qhov tsawg kawg nkaus yield zog ntawm X70 yog hais txog 483MPa, thiab qhov tsawg kawg nkaus yield zog ntawm X80 yog hais txog 552MPa. Cov ntaub ntawv qib siab dua no feem ntau yog siv rau hauv cov ntawv siv high-pressure, xws li ntev-ntev, loj-diameter high-pressure roj thiab roj kis kab mob, lossis hauv cov roj hauv hiav txwv tob thiab cov roj rho tawm, qhov twg cov kav dej yuav tsum muaj zog heev thiab Kev txo qhov hnyav yog qhov tseem ceeb, thaum L360 PSL2 nyuaj kom ua tau raws li qhov xav tau muaj zog txaus.
Ntsuas lub zog thiab weldability:
Ib qho txiaj ntsig tseem ceeb ntawm L360 PSL2 piv rau cov qib siab dua yog nws qhov zoo tshaj plaws weldability. Raws li lub zog tawm los ntawm qib siab dua steel nce, nws cov pa roj carbon sib npaug feem ntau nce, uas ua rau vuam nyuaj thiab yuav tsum muaj cov txheej txheem vuam ntau dua thiab cov txheej txheem vuam ntau dua thiab cov kws tshaj lij welding. Txawm li cas los xij, vim nws lub zog nruab nrab, L360 PSL2 kuj yooj yim rau kev khiav lag luam thaum lub sij hawm vuam, thiab cov vuam zoo yog yooj yim dua los xyuas kom meej, uas tuaj yeem txo cov nqi vuam thiab qhov tshwm sim ntawm vuam tsis xws luag, thiab yooj yim dua los tsim hauv cov kav dej zoo tib yam. kev tsim kho tej yaam num.
Cov ntsiab lus toughness:
L360 PSL2 feem ntau muab qhov sib npaug zoo ntawm lub zog thiab tawv. Txawm hais tias qib siab dua ntawm cov raj xa dej tuaj yeem muab lub zog ntau dua, lawv qhov toughness feem ntau txo. Hauv kev siv cov raj xa dej, lub zog yog qhov tseem ceeb rau inhibiting tiam thiab nthuav ntawm cov kab nrib pleb. L360 PSL2 tuaj yeem tswj tau qhov tawv ntawm cov khoom thaum ua tau raws li qee qhov yuav tsum tau muaj zog. Nws tuaj yeem tiv thaiv cov raj xa dej tsis ua haujlwm vim qhov tawg tawg hauv cov kav dej tso rau thaj chaw uas muaj cov txheej txheem geological, tuaj yeem cuam tshuam rau sab nraud lossis qhov kub thiab txias hloov, thiab xyuas kom muaj kev nyab xeeb thiab ruaj khov ntawm cov kav dej.
