PSL2 Cov Kev Xav Tau Zoo
API 5L Gr.B PSL2 seamless yeeb nkab ua raws cov tubing specification tsim los ntawm American Petroleum Institute, qhov twg PSL2 qhia txog cov kev cai nruj dua. Piv nrog PSL1, PSL2 seamless kav xav tau kev txhim kho tshuaj lom neeg muaj pes tsawg leeg ntawm kev tswj hwm, kev sim ua kom zoo, thiab ua kom tsis muaj -cov qauv ntsuas kev puas tsuaj, ntxiv rau qhov yuav tsum tau kuaj xyuas Charpy thiab tag nrho traceability.
Technical Advantage
Dimensional precision: ib 168.3 hli sab nraud txoj kab uas hla muaj ib tug kam rau ua ntawm ntxiv los yog rho tawm 1 feem pua, thiab phab ntsa thickness sib txawv nyob rau hauv ntxiv los yog rho tawm 10 feem pua. Corrosion resistance: kev pab cuam lub neej txuas ntxiv ntawm cov txheej xws li 3PE lossis corrosion inhibitors. Weldability: cov carbon sib npaug, CE, tsuas yog 0.43 feem pua ntawm cov qauv IIW, tsim nyog rau kev ua haujlwm ntawm lub voj voog vuam.
Composition thiab Mechanical Properties
Rau PSL2 Qib B, carbon yog 0.22 feem pua siab tshaj plaws, manganese 1.20 feem pua siab tshaj plaws, phosphorus 0.025 feem pua siab tshaj plaws, thiab sulfur 0.015 feem pua siab tshaj. Lub zog tensile yog 60,000 txog 110,000 psi, 414 txog 758 MPa, thiab lub zog tawm los yog 35,000 txog 65,000 psi, 241 txog 448 MPa. Cov pa roj carbon sib npaug yog 0.25 rau cov qauv PCM thiab 0.43 rau cov qauv IIW, thiab lub zog cuam tshuam yog 27 J transverse thiab 41 J longitudinal.
PSL1 vs PSL2 sib piv
Charpy Impact test tsis tas yuav tsum muaj rau PSL1 tab sis yuav tsum muaj rau txhua qib PSL2. Tsis yog -kev tshuaj xyuas ntawm cov yeeb nkab seamless tsuas yog ua raws li PSL1 thaum tau teev tseg, tab sis yuav tsum tau ua raws li PSL2. Certification thiab traceability yog xaiv tau raws li PSL1 thiab yuav tsum tau nyob rau hauv PSL2, thiab hydrostatic kuaj yuav tsum tau rau ob leeg.
Txheej txheem ntau lawm
Txoj kev tsim khoom seamless pib nrog cov cua kub cua sov ntawm 1200 ntxiv lossis rho tawm 50 degrees C, tho cov khoom billet rau hauv lub plhaub hollow ntawm tus ntoo khaub lig- yob tho qhov zeb, dov thiab sizing rau cov phab ntsa uas tau teev tseg, kev kho cua sov los ntawm normalizing los yog quenching thiab tempering rau optimized metallography, thiab tiav nrog cov txheej txheem polishing.
