Qhov sib txawv ntawm API 5L PSL1 thiab PSL2:
API 5L tus qauv muaj cov kev cai ntawm ob theem khoom lag luam tshwj xeeb (PSL1 thiab PSL2). Ob yam ntawm cov khoom kwv yees ntawm cov khoom lag luam rau cov qauv txheej txheem ntawm cov txheej txheem sib txawv, cov ntsiab lus tshaj plaws muaj zog thiab lub zog tensile tau ua rau cov tseev kom muaj.
PSL yog luv luv rau qib khoom lag luam qib. API 5L Kab Yeeb Yam Khoom Tshwj Xeeb Qib yog muab faib ua PSL1 thiab PSL2, kuj tseem tuaj yeem hais cov qhab nia zoo tau muab faib ua PSL1 thiab PSL2. PSL2 saum toj no PSL1, ob qib no tsuas yog kev tshuaj ntsuam xyuas, yog li cov lus cog tseg hauv API, yog li kev txiav txim siab ntawm cov khoom lag luam cov khoom lag luam, yog li ntawv sau cov khoom lag luam, uas yog PSL1 lossis PSL2.
PSL2 hauv tshuaj lom neeg, tensile cov khoom, tej yam kev sim siab, thiab kev sim siab tshaj plaws hauv PSL1 ntsuas. PSL1 tsis tas yuav muaj kev cuam tshuam cov kev ua tau zoo, PSL2 tag nrho tsuas yog x80 Qeb Akv: Degree Intal Qib: Degree 101 J, los yog ib sab Acuity 68 J. Cov yeeb nkab kab yuav tsum tau kuaj dej siab, thiab cov qauv tsis raug cai ntawm lub teb chaws siab ntawm peb lub teb chaws.
Txheej txheem tsim khoom:
Seamless Yeeb Nkab: tsim los ntawm kub dov lossis cov txheej txheem kos duab txias, haum rau kev ua kom siab thiab cov nqi ntawm qhov siab me me, tab sis tus nqi siab dua.
Welded Yeeb Nkab: suav nrog cov zog siab tiv thaiv hluav taws xob tiv thaiv (Hlob) Thiab submerged arc vuam (Txiav ntoo), uas dominates lub teb ntawm txoj kab uas loj loj (xws li loj dua los yog sib npaug rau 24 ntiv tes) thiab muaj tus nqi qis dua.
