Mild Steel Pipes are widely used for their high corrosion resistance and suitable mechanical properties in industries such as ship built and boilers, nuclear devices, gas transport, and the petrol-chemical industry.

Mild steel pipe, also known as low-carbon steel pipe, is the most typical form of steel due to its low price and suitable material properties. Iron and a small amount of carbon deliver strength and tenacity.
