What is L245 spiral steel pipe

L245 is the domestic standard low-end pipeline steel, the implementation standard is GB/T9711, steel pipe for pipeline transportation system in oil and gas industry.

L245 Spiral Tube Introduction:
L means (Line) pipeline
245 means yield strength ≥ 245Mpa

Chemical composition of L245 spiral steel pipe:
C (carbon) 0.26,
Mn (manganese) 1.15,
sulfur (S) ≤ 0.030
phosphorus (P) ≤ 0.030,

Compared with Q235B spiral steel pipe, L245 spiral steel pipe has superior performance, higher mechanical properties and better plasticity, and its welding can also use a welding rod with Q235b material, so its price is higher than Q235B spiral steel pipe.

L245 spiral steel pipe is mainly used in oil pipelines and natural gas pipelines, and generally the outer wall needs to be treated with 3pe anticorrosion, and the service life can reach 50 years.
