X42 yog cov yeeb nkab steel qib tau muab faib ua nruab nrab - lub zog carbon steel. Tus "X" hauv nws lub npe qhiapipeline hlau, thaum "42" qhia tias a42,000 psi (kwv yees li 290 MPa). Kuj raug xaiv uaL290, nws conformsAPI 5L tus qauv. X42 kab yeeb nkab tuaj yeem tsim los ua ib qhoseamless los yog welded steel kav, nyob ntawm daim ntawv thov xav tau. Cov txheej txheem ntau lawm suav nrogKub dov, txias sib sau, thiab vuam cov txheej txheemkom ntseeg tau tias cov khoom siv sib xws thiab tshuaj lom neeg muaj pes tsawg leeg.
