What is an X46 pipe?

API 5L X46 is a medium-strength carbon steel pipe grade utilized in pipeline transportation systems for petroleum, natural gas, and water. Although it is not as frequently used as higher grades like X52 or X60, X46 remains a reliable option for certain low-to-medium pressure projects and legacy systems.

 

What is the yield strength of X46?

API 5L X46 steel pipe has a minimum yield strength of 46,400 psi or 320 Mpa. The current X46 steel pipe are all controlled micro-alloyed carbon-manganese steels.
