Thaum cov txheej txheem kev xeem uas tau teev tseg hauv API 5L cov lus qhia siv rau PSL1 thiab PSL2 cov kav dej, PSL2 kev faib tawm kuj tuaj nrog cov kev ntsuas ntxiv txhawm rau txhawm rau ua kom zoo thiab tsim nyog ntawm cov kav dej rau cov ntawv thov tseem ceeb. Cov kev ntsuam xyuas ntxiv thiab ib txwm muaj xws li:
Kev tswj cov tshuaj muaj pes tsawg leeg: PSL2 yuav tsum tswj cov tshuaj muaj pes tsawg leeg nruj dua li PSL1, suav nrog ntau dua purity thiab qis cov ntsiab lus ntawm cov ntsiab lus tsis zoo.
Cov khoom siv tshuab: PSL2 muaj qhov xav tau ntau dua ntawm cov khoom tensile, kev cuam tshuam tsis kam, thiab lwm yam kom tsis txhob tawg tawg. Tsis tas li ntawd, PSL2 kuj muaj cov kev xav tau siab dua rau lub zog tensile thiab lub zog tawm los.
Kev ntsuam xyuas tsis muaj kev puas tsuaj: PSL2 yuav tsum tsis muaj kev puas tsuaj ntawm txhua cov yeeb nkab kom ntseeg tau tias muaj kev nyab xeeb thiab kev ncaj ncees ntawm cov kav dej. Cov kev sim tshwj xeeb yuav suav nrog kev kuaj hluav taws xob, kuaj ultrasonic, thiab lwm yam.
Kev ntsuam xyuas hydrostatic : PSL2 yuav tsum tau kuaj hydrostatic ntawm txhua cov yeeb nkab, thiab kev sim tsis muaj kev puas tsuaj tsis tuaj yeem siv los ntawm kev sim hydrostatic.
Yeeb Nkab End Kev Kho Mob: Cov yeeb nkab kawg ntawm PSL2 xav tau sandblasting kom ntseeg tau tias vuam zoo thiab txo cov kev pheej hmoo corrosion
Low Temperature CVN Impact Test: Qhov kev ntsuam xyuas no ntsuas qhov cuam tshuam ntawm cov kav dej ntawm qhov kub thiab txias (feem ntau qis li -40 degree (-40 degree F) lossis qis dua) kom ntseeg tau tias kev ua haujlwm ntawm cov kav dej thaum lub sijhawm ua haujlwm nyob rau hauv huab cua txias los yog lub caij ntuj no.
Weldability Test: Qhov kev ntsuam xyuas no ntsuas lub peev xwm ntawm cov raj xa dej kom welded yam tsis muaj kev cuam tshuam rau nws cov khoom siv kho tshuab, ua kom muaj kev ncaj ncees ntawm cov khoom sib txuas.
Hardness Test: Qhov kev ntsuam xyuas no ntsuas qhov hardness ntawm lub raj xa dej, uas yog ib qho tseem ceeb rau kev tiv thaiv hnav, puas thiab deformation thaum lub sij hawm installation thiab ua haujlwm.
Drop Weight Tear Test (DWTT): Qhov kev ntsuam xyuas no ntsuas lub raj xa dej kom tsis txhob tawg, uas yog ib qho tseem ceeb los xyuas kom meej qhov kev ncaj ncees ntawm cov kav dej hauv kev siv hluav taws xob siab, kev ntxhov siab.
