Hauv cov qauv kev lag luam roj thiab roj (xws liAPI 5Lrau kab yeeb thiabAPI 5 CTrau casing thiab tubing),PSLsawv rauKhoom Specification Level.
Nws txhais cov qib sib txawv ntawm qhov ua tau zoo thiab cov kev ntsuas rau tib qib steel (xws li X52 lossisL80). Raws li qib nce (los ntawm PSL1 mus rau PSL3), cov kev xav tau ua kom nruj dua.

Dhia tob rau hauv Txhua Qib
PSL1: Txuj Zoo
Qhov chaw:Nkag mus - theem qib ntawm API cov qauv.
Cov yam ntxwv tseem ceeb:Nws tsis xav tau Carbon Equivalent (CEQ) xam los yog ntsuas qhov cuam tshuam rau qhov toughness.
Buyer Pain Point:Nws yog qhov kev xaiv pheej yig tshaj plaws tab sis muaj kev pheej hmoo ntawmbrittle tsis ua hauj lwmnyob rau hauv qhov chaw txias. Nws yog feem ntau yog siv rau cov dej qhov dej los yog qis - cov roj qhov dej siab.
PSL2: Kev Lag Luam Standard (Feem ntau)
Qhov chaw:Qhov yuav tsum tau ua rau feem ntau niaj hnub roj / roj xa cov kav dej thiab cov txheej txheem drilling.
Cov yam ntxwv tseem ceeb:
Toughness:Yuav tsum dhau qhovCharpy V-Notch (CVN)cuam tshuam kev kuaj xyuas kom cov hlau tsis tawg ntawm qhov kub thiab txias.
Weldability:Cov kev txwv nruj ntawm Carbon Equivalent (CEQ) kom ntseeg tau tias kev sib txuas ua haujlwm yooj yim, muaj zog, thiab txhim khu kev qha.
Cov neeg yuav khoom tsom:Qhov no yog "qhov chaw qab zib" ntawm tus nqi thiab kev nyab xeeb. Feem ntau cov kev sib tw thoob ntiaj teb xav tau PSL2 yam tsawg kawg nkaus.
PSL3: Zoo heev (API 5CT nkaus xwb)
Qhov chaw:Tshwj xeeb yog tsim los rau cov chaw ua haujlwm txaus ntshai tshaj plaws lossis tseem ceeb.
Cov yam ntxwv tseem ceeb:
Kev tshuaj xyuas tag nrho:Txhua lub yeeb nkab yuav tsum tau ua kom nruj tshaj NDT (Ultrasonic lossis Electromagnetic) kom ntseeg tau tias xoom micro- tawg hauv cov yeeb nkab lub cev.
Dimensional Precision:Tighter tolerances ntawm OD thiab phab ntsa thickness piv rau PSL2.
Daim ntawv thov:Deepsea drilling, siab -cov roj qhov dej siab, lossis cov kav dej nyob ze ntawm thaj chaw muaj neeg nyob.
3 Kev txhawj xeeb rau cov neeg yuav khoom txawv teb chaws
NtawmGNEE, peb pab peb cov neeg siv khoom nrhiav qhov sib txawv no los ntawm kev tsom mus rau:
"Kuv puas xav tau PSL2 tiag tiag?"
Tswv yim:Yog tias koj qhov project nyob hauv thaj chaw txias (xws li Canada, Kazakhstan) lossis koom nrognatural gas, PSL2 yog qhov yuav tsum tau ua. Qhov kev pheej hmoo ntawm cov pa xau yog ntau dua li cov kua dej, thiab PSL2 lub zog yog koj qhov kev pov hwm kev nyab xeeb.
Yuav ua li cas txheeb xyuas PSL qib?
GNEE Advantage:Xyuas covMTC (Mill Test Certificate). PSL1 MTC yog qhov yooj yim, tab sis PSL2 MTCyuav tsumsuav nrog CEQ qhov tseem ceeb thiab cov ntaub ntawv tshwj xeeb CVN cuam tshuam. Peb txhawb nqa Thib Peb-Kev Tshawb Fawb Kev Tshawb Fawb (SGS/BV) los ua pov thawj cov kev xeem no.
Lead Time Differences:
Tswv yim:PSL1 feem ntau muaj nyob rau hauv Tshuag. PSL2 thiab PSL3 feem ntau xav tau kev tsim khoom vim yog cov khoom siv nruj thiab NDT cov cai. GNEE cov khoom siv saw hlau tuaj yeem txo PSL2 ntau lawm mus txog li 20%.

FAQ
Q: Puas muaj qhov sib txawv ntawm lub cev ntawm PSL1 thiab PSL2 kav?
A:Lawv saib ze li qub, tab sis covstencilingyog txawv. PSL2 cov kav dej tau pom meej meej nrog "PSL2." Tsis tas li ntawd, cov kav dej PSL2 feem ntau muaj qhov ua tiav zoo dua vim tias tag nrho - lub cev NDT yuav tsum muaj qhov chaw du kom raug ntsuas qhov ntsuas.
Q: Vim li cas PSL2 kim dua PSL1?
A:Tus nqi ntxiv yog los ntawm: 1.Cleaner raw khoom(purer steel yaj); 2.Yuav tsum tau kuaj cov nqi(CVN xeem, CEQ tsom xam); 3.NDT fee(tus nqi ntawm kev khiav cov cuab yeej scanning siab heev).
Q: GNEE puas tuaj yeem muab PSL3?
A:Yog lawm. GNEE muaj peev xwm tsim API 5CT PSL3 casing thiab tubing, nruab nrog lub xeev - ntawm -the -art automated NDT kab kom ntseeg tau 100% ua raws.
