X42 seamless steel yeeb nkab, tseem hu ua L290 pipeline steel, yog qis - carbon microalloyed steel yeeb nkab ua raws li API SPEC 5L cov qauv. Nws yog tsim los ntawm Mn-Mo-Nb-Ti microalloying tsim thiab tswj dov thiab txias txheej txheem, ua tiav qhov tsawg kawg nkaus lub zog ntawm 290 MPa (42 ksi), yog li lub npe "X42". Cov khoom siv no ua ke zoo weldability nrog kev tiv thaiv hydrogen-induced cracking (HIC), tuav ruaj khov cuam tshuam toughness txawm nyob rau ntawm -20 degree, ua rau nws tus nqi-zoo thiab txhim khu kev qha industrial conveying steel.
X42 seamless steel kav yuav tsum nruj me ntsis ua raws li cov ntsiab lus tseem ceeb ntawm API SPEC 5L, 46th edition, thiab kuj ua tau raws li cov kev cai sib xws ntawm lub teb chaws tus qauv GB/T 9711. Cov qauv sib npaug thoob ntiaj teb suav nrog EN 10208-2 L290 thiab ISO 3183 L2 Cov qauv qhia meej meej xav tau: sab nraud txoj kab sib txawv tsawg dua lossis sib npaug li ± 0.75%, phab ntsa thickness kam rau ua tswj tsis pub dhau +15%/-12.5%; 100% kev soj ntsuam ultrasonic thiab eddy tam sim no kuaj yuav tsum tau, nrog rau kev kuaj pom rhiab heev ncav cuag qhov sib npaug ntawm Φ1.6 hli ca-hauv qab qhov; Cov khoom lag luam tseem ceeb tau dhau SGS qhov kev ntsuam xyuas thib peb, thiab qhov ntsuas hydrostatic siab tsis tsawg dua 15MPa.
