X70 pipeline steel is used to transport oil, natural gas and other pipelines.

According to the difference in thickness and subsequent formation, X70 pipeline steel can be produced by hot continuous rolling mill, furnace coil mill or medium and heavy plate mill, and formed into large-diameter steel pipe by spiral welding or UOE straight seam welding.
