What is API 5L X70 Pipe
X70 line pipe is a specialized pipeline product used in the oil and gas industry for transporting media such as oxygen, water, and oil, conforming to the API SPEC 5L international standard. Its specifications cover outer diameters of 8-1240mm, wall thicknesses of 1-200mm, and yield strengths up to 485MPa (70kpsi). Production grades range from B and X42 to X70, and the molybdenum content can be adjusted (up to 0.35%) to meet different engineering needs.
