API 5L X60 thiab A106 GR.B yog ob yam khoom siv yeeb nkab sib txawv rau kev siv thiab cov qauv sib txawv.
API 5L X60:
- Siv: Feem ntau yog siv rau cov roj thiab roj tsheb thauj mus los.
- Standard: Ua raws li American Petroleum Institute (API) cov qauv.
- Yam ntxwv: Qhov tsawg kawg nkaus tawm lub zog ntawm X60 qib steel yeeb nkab yog 555MPa. Cov yeeb nkab steel no txhim kho cov khoom siv ntawm cov hlau los ntawm kev tswj cov txheej txheem dov, cov ntsiab lus tseem ceeb xws li Nb, V, Ti, thiab lwm yam, thiab cov ntsiab lus carbon yog tswj ntawm 0.1-0.14%, uas ua kom ntseeg tau. kev nyab xeeb ntawm cov yeeb nkab steel hauv kev siv cov kev kub ntxhov thiab hnyav ib puag ncig los ntawm cov txheej txheem no.
A106 PAB:
- Siv: Feem ntau yog siv rau hauv cov kav dej hauv qhov kub thiab txias ib puag ncig, xws li kev lag luam tshuaj, hluav taws xob thiab roj av refining.
- Txuj: Ua raws li ASTM tus qauv thoob ntiaj teb.
- Yam ntxwv: Lub zog tensile ntawm A106 GR.B steel yeeb nkab yog tsawg kawg yog 415MPa thiab lub zog tawm los yog 240MPa. Cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab ntawm cov yeeb nkab steel no tau ua tib zoo tsim los xyuas kom muaj kev ruaj ntseg thiab kev nyab xeeb hauv qhov kub thiab txias ib puag ncig.
