API 5L Grade B Line Pipe Physical Properties

API 5L Grade B Line Pipe Physical Properties

Line pipe grade designations come from API Spec 5L Specification for Line Pipe. Standard Line Pipe has grade designation A and B. Stronger grades have the designation X followed by the specified minimum yield strength of the pipe steel, measured in kilopounds per square inch (abbreviated ksi), e.g. X60 for pipe having a minimum yield strength of 60 ksi. See the table below for the standard available grades.

1 -API 5L elongation figures vary with specimen dimensions. Values shown for 0.2 sq. in. specimen.

Line pipe mechanical testing usually omits Reduction of Area (RA) measurement reporting, and Charpy V-Notch (CVN) testing. This prevents use of this pipe as body material above 36 ksi yield strength for API Spec 6A equipment without retesting for Reduction of Area, and in the case of low temperature service, Charpy V-Notch testing as well.

API 5L Grade B, x42,x46,x52,X56,x56,x60,x70 Carbon Steel Seamless Pipe Packing

API 5L Grade B, x42,x46,x52,X56,x56,x60,x70 Carbon Steel Seamless Pipe is sleeved into plastic bag individually, pieces wrapped with water-proof material, bundled with nylon rope. Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. Great care is taken during operation and transportation.
