API 5L X56 specification yog dab tsi?
X56 kab yeeb nkab belongs rau kev faib qib steel hauv API 5L tus qauv. Lub "X" nyob rau hauv nws lub npe sawv cev rau cov kab hlau, thiab "56" qhia qhov tsawg kawg nkaus yield zog ntawm 56,000 psi (kwv yees li 386 MPa). Hom yeeb nkab no feem ntau yog ua los ntawm cov pa roj carbon steel los yog qis- alloy steel, muaj lub zog siab thiab zoo toughness, thiab haum rau nruab nrab - siab conveying ib puag ncig.
Tshuaj muaj pes tsawg leeg
C (Carbon): Tsawg dua lossis sib npaug li 0.12% (Cov pa roj carbon tsawg los txhim kho weldability)
Mn (Manganese): 1.2% -1.6% (Lub zog muaj zog)
Si (Silicon): Tsawg dua lossis sib npaug li 0.45%
Nb (Niobium), V (Vanium), Ti (Titanium): Cov nqi (Refines nplej, txhim kho toughness)
S (Sulfur), P (Phosphorus): Tsawg dua lossis sib npaug li 0.015% (Tsawg impurities txhim kho corrosion kuj)
Mechanical Properties
Yield Strength (σs): Ntau dua lossis sib npaug li 390 MPa
Tensile zog (σb): 490-620 MPa
Elongation (δ): Ntau dua lossis sib npaug li 20% (Txhim kho qhov ductility)
Impact Toughness: Yuav tsum ua kom tau raws li qhov yuav tsum tau muaj qhov kub thiab txias (piv txwv li, Charpy impact test Ntau dua lossis sib npaug li 40J ntawm -20 degree)
Hardness: Feem ntau Tsawg dua los yog sib npaug rau 250 HB (Tshuaj tiv thaiv vuam tawg)
X56 seamless yeeb nkab Daim Ntawv Thov Scenario
X56 pipeline yeeb nkab yog siv rau hauv cov nram qab no:
- Ntev-cov roj thiab cov roj nkev xa mus ntev
- Nruab nrab- ntu siab ntawm cov pa hluav taws xob hauv nroog
- Kev thauj mus los ntawm cov khoom tsis yog -corrosive media hauv kev lag luam tshuaj
- Cov kav dej siab hauv cov dej txuag dej
Nws qhov chaw ua haujlwm feem ntau yog nruab nrab ntawm qhov qub thiab nruab nrab - qhov kub thiab txias. Kev soj ntsuam ntxiv ntawm cov khoom siv adaptability yuav tsum tau nyob rau hauv huab cua kub lossis kub kub.
API 5L X56 PSL1 PSL2 pipeline Production Process thiab Key Technologies
Kev tsim cov yeeb nkab X56 feem ntau suav nrog cov kauj ruam hauv qab no:
- Steelmaking: Smelting nyob rau hauv lub converter los yog hluav taws xob rauv, tswj cov ntsiab lus ntawm impurities xws li sulfur thiab phosphorus.
- Rolling: Refining nplej thiab txhim kho lub zog los ntawm thermomechanical dov.
- Kev Tsim: Kev tsim cov kav hlau siv cov txheej txheem xws li JCOE lossis UOE.
- Vuam: Siab- zaus welding (HFW) lossis submerged arc vuam (SAW).
- Kev kho cua sov: Qee cov khoom lag luam xav tau kev kho mob kom zoo dua qub.
- Kev tshuaj xyuas: suav nrog cov khoom tshuaj xyuas zoo xws li kev kuaj xyuas qhov tsis zoo ntawm ultrasonic thiab kuaj hydrostatic.
