X42 large-diameter welded pipe belongs to the medium-strength pipeline steel series, with a minimum yield strength of 290MPa (42 klb/sq inch), and is widely used in onshore and offshore oil and gas transportation projects.
GNEE Group’s API 5L X42 welded pipes are used not only for onshore oil and gas transportation but also widely in subsea pipeline projects. Their outer diameter typically ranges from 219mm to 1422mm, with wall thickness adjusted according to pressure rating. Common steel grades include X42, X52, X60, and X70, each corresponding to different yield strengths. Selecting the appropriate steel grade and specifications requires a comprehensive evaluation considering the transported medium, operating pressure, and ambient temperature.
API 5L X42 Welded Pipe Specifications:
