1. ** Dab tsi yog API 5L X65 PSL2 khoom? **
API 5L X65 PSL2 yog cov khoom siv hluav taws xob muaj zog Nws muaj tsawg kawg yog cov txiaj ntsig lub zog ntawm 65,000 psi (448 MPA yuav tsum muaj cov khoom lag luam tshwj xeeb
2. ** Dab tsi yog API 5L Qib B PSL2 sib npaug rau? **
API 5L Qib B PSL2 yog kwv yees sib npaug rau ASTM A53 Qib B (Seamless / Welded) lossis AGTM A106 qib ntawm cov khoom siv khoom siv. Txawm li cas los xij, PSL2 imposes Stricter tswj ntawm tshuaj lom neeg, kev ntsuas kev nruj, thiab tsis yog-kev ua kom muaj kev puas tsuaj rau cov qib ATM qib.
3. ** PSL2 txhais li cas rau cov yeeb nkab? **
PSL2 (Theem Khoom Tshwj Xeeb 2) Qhia txog tias cov yeeb nkab sib ntsib zoo dua thiab ua tau zoo dua PSL1. PSL2 kav dej yauv unicego stricter tshuaj lom neeg cov kev txwv, txhim kho kev kuaj xyuas cov neeg kho mob (suav nrog kev sib cuam tshuam kev sib raug zoo kom ua tau zoo dua rau cov ntawv thov siab lossis qis-kub ib puag ncig.
4. ** Dab tsi yog qhov sib txawv ntawm API 5L X65 PSL1 thiab PSL2? **
Lub ntsiab sib txawv ntawm API 5L X65 PSL1 thiab PSL2 yog:
- ** Cov tshuaj xyaw: ** PSL2 muaj cov txwv tsis pub muaj carbon, leej faj, thiab phosphorus.
- ** Kev Kuaj Me: ** PSL2 xav tau Charpy cuam tshuam kev sim ua kom pom tseeb.
- ** Tsis yog-kev sim ua txhaum (NDT): ** PSL2 ua kom puv-ntev ndt (piv txwv li, kev kuaj ultrasonic).
- ** EQUENSION TUAM: ** PSL2 muaj qhov ntsuas ntawm qhov ntev thiab tsis xws luag.
PSL2 yog siv nyob rau hauv cov ntawv thov tseem ceeb tshaj qhov uas xav tau kev txhawb siab ntxiv.
5. ** Dab tsi cov khoom siv yog API 5L X65 sib npaug rau? **
API 5L X65 yog ib yam li cov qauv thoob ntiaj teb, suav nrog:
- ** ASTM: ** piv rau high-zog qib zoo li astm A106 qib C lossis AVEM A333 qib 6 (rau tsawg-kub siv).
- ** Rau (European): ** Nyob ze rau L450MB lossis L450NB hauv EN 10224 / EN 10208.
- ** ISO 3183: ** Ua kom ncaj qha nrog ISO 3183 L450m lossis L450n.
Txawm li cas los xij, kev sib txig sib luag yog nyob ntawm cov kev xav tau ntxiv xws li PSL2 kuaj.
