The mechanical properties of Mild Steel Pipe

Mild steel pipes and is one of the low carbon steel pipes with low carbon content and the lesser hardness. Plus a small amount of pearlite microstructure of ferrite is characterized by low hardness (HB 100-130), low intensity (σb 372 ~ 470MPa) and high plasticity (δ 24 percent to 36 percent), and formability and good weldability.

Seamless Steel Pipe

Seamless Steel Pipe(SMLS) is made from a solid round steel billet which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. The seamless pipe is then finished to dimensional and wall thickness specifications in sizes from 1/8'' to 36'' OD.
