API 5L Carbon Steel Seamless Pipe Tubes

L245NB belongs to a type of petroleum pipeline pipe. Better than L245 material, N in L245NB indicates that L245 steel has undergone deformation normalization. B means B-grade steel pipe. So L245NB represents deformation normalization based on L245. Chemical composition and mechanical properties of L245NB petroleum pipeline pipe: Chemical composition: C: 0.26 Mn: 1.15 S: not more than 0.030 P: not more than 0.030 Mechanical properties: Yield strength: 245 MPa Tensile strength: 415 MPa Elongation: 21 min L245NB Petroleum pipeline pipe Executive standard: GB9711.2-2017 L245NB Petroleum pipeline pipe Specification: Outer diameter 60-726 * Wall thickness 3-60   L245 pipeline pipe, specification 8-1240 × 1-200mm, standard API SPEC, mainly used for gas, water, and oil transportation in the natural gas industry.
