L555 steel welded yeeb nkab

Dab tsi yog cov khoom siv ntawm API 5L X80 yeeb nkab?

Cov tshuaj lom neeg muaj pes tsawg leeg thiab kev tsim khoom ua kom cov khoom zoo rau cov kav dej siv rau hauv ntau daim ntawv thov hauv ntau qhov chaw. Yog li kev paub txog lub cev thiab cov khoom siv kho tshuab yog qhov tseem ceeb los yuav cov kav dej zoo tshaj plaws.

Raws li tus thawj coj nrog lub npe nrov yeeb nkab xa khoom, kuv paub cov khoom siv ntawm API 5L X 80 yeeb nkab thiab lwm cov kav dej. Li no kuv tuaj yeem teb ntau cov lus nug txog nws, los ntawm cov khoom mus rau hom thiab qhov sib txawv nrog lwm tus.

Cov khoom siv tshuab zoo li yuav ua li cas cov yeeb nkab tuaj yeem tiv taus qhov kub thiab txias nrog lub zog txaus yog qhov tseem ceeb kom paub rau cov neeg yuav khoom. Txawm hais tias lub cev muaj zog xws li xim, melting point, ntom thiab lwm yam tseem ceeb, cov khoom siv kho tshuab ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm zoo ntawm cov yeeb nkab.

Zoo li lwm tus, API 5L X 80 steel kav muaj ob yam khoom tshwj xeeb, PSL1 thiab PSL 2, muaj nyob rau hauv cov ntaub ntawv welded thiab seamless. Thiab nyob ntawm cov khoom lag luam thiab cov ntaub ntawv no, cov khoom siv kho tshuab ntawm cov kav dej sib txawv rau kev siv ntau yam.

Muaj ntau yam khoom siv ntawm cov kav dej los xyuas ua ntej yuav, thiab ob peb ntawm lawv rau API 5L X80 welded yeeb nkab thiab lwm yam muaj xws li tensile zog yog 625 MPa thiab yield zog yog 555 MPa.

Qhov txawv ntawm X70 thiab X80 yeeb nkab yog dab tsi?

X 70 thiab X 80 kav yog ib feem ntawm X series ntawm cov kav dej ua raws li API 5L specifications. Tab sis kuj tseem muaj ntau qhov sib txawv ntawm ob qho uas suav nrog.

Cov ntsiab lus carbon ntawm X 80 tsawg dua ntawm 0.08% dua li cov pa roj carbon ntau dua ntawm 0.28%

Cov ntsiab lus silicon ntawm X 80 siab dua ntawm 0.26% dua li 0.03% hauv X 70

Cov ntsiab lus manganese ntawm X 80 yog siab dua ntawm 1.75% dua li 1.5% hauv X 70

Dab tsi yog kev siv ntawm API 5L qib X80 yeeb nkab?

Vim tias nws cov ntsiab lus siab manganese nrog rau txhuas, molybdenum, niobium, vanadium, tin, thiab lwm yam, API 5L qib X80 yeeb nkab yog qhov tseem ceeb hauv ntau daim ntawv thov hauv ntau qhov chaw. Qee qhov kev siv no suav nrog.
