Khoom Description
API 5L X52MS PSL2 welded yeeb nkab yog qhov siab - cov yeeb nkab ua haujlwm tau tsim los rau cov kev pabcuam qaub hauv kev lag luam roj thiab roj. Qhov kev xaiv "X52" qhia qhov tsawg kawg nkaus tawm lub zog ntawm 52,000 psi (359 MPa). Cov lus "MS" txhais tau tias M (Thermomechanical dov) + S (Sour Service), qhia tias cov yeeb nkab yog tsim tshwj xeeb los tiv thaiv hydrogen-induced cracking (HIC) thiab sulfide stress cracking (SSC) in H₂S{12}}muaj ib puag ncig.
PSL2 (Product Specification Level 2) sawv cev rau qib siab dua nrog cov kev cai nruj dua rau cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, kev cuam tshuam toughness, thiab tsis yog- kev kuaj kev puas tsuaj piv rau PSL1.

| Hardness txwv | Tsis tau teev tseg | Specified (tsawg dua lossis sib npaug rau 250 HV10) |
PSL2 yog qhov yuav tsum tau ua rau cov ntawv thov kev pabcuam qaub
Q3: Vim li cas thiaj xaiv X52MS dhau tus qauv X52?
A: Txheem X52 yog tsim rau "qab zib" (tsis yog -H₂S) kev pabcuam. X52MS suav nrog cov kev xav tau ntxiv nrog rau cov ntsiab lus qis dua sulfur / phosphorus, kev tswj hwm nruj dua, thiab yuav tsum kuaj HIC / SSC kom ntseeg tau tias muaj kev nyab xeeb hauv thaj chaw acidic uas muaj hydrogen sulfide.
Q4: Qhov kev ntsuam xyuas dab tsi yog X52MS PSL2 yeeb nkab?
A: Ntxiv rau cov qauv PSL2 cov cai (Charpy impact test, hydrostatic test, ultrasonic/radiographic NDT), X52MS kav yuav tsum dhau:
HIC Test- Hydrogen{0}}Induced Cracking resistance
SSC Test- Sulfide Stress Cracking kuj
Kev Xeem Hardness- Raws li API 5L 46th Edition cov cai rau kev pabcuam qaub
