L360 spiral steel pipe

Description: L360 spiral steel pipe is a method of arc welding under the flux layer, which utilizes the heat generated by the arc burning between the welding wire and flux under the flux layer to melt the welding wire, flux, and base metal.

Chemical composition of L360 spiral steel pipe: C: ≤ 0.20, Si: ≤ 0.45, Mn: ≤ 1.60, P: ≤ 0.020, S: ≤ 0.010, V: ≤ 0.10, Nb: ≤ 0.05, Ti: ≤ 0.04, CEV ≤ 0.45.
