As a professional steel pipe manufacturer, we also provide various line pipes, including multiple API 5L pipes. API 5L pipe line is a transportation method used to transport oil, water and natural gas to the oil and gas industry company through pipeline. Our X52 Line Pipe, X56 Line Pipe, X60 Line Pipe and X70 Line Pipe are the tools used for their transportation. The yield strength of the pipe is specified by the number following the X in the material grade name (in kilograms per square inch, or KSI). So, for example, the minimum yield strength of API 5L X70 pipes is 70 KSI. In addition, we also supply products that meet ASTM A333 pipeline grade specifications. Our A333 Grade 6 Pipe can provide customers with pipes of different sizes, specifications, grade materials and shapes at market leading prices
