Product Introduction

Carbon steel pipe is a kind of steel pipe alloy, which is made of solid round steel or steel ingot as raw material, and then made into capillary by piercing process, and then made by hot rolling or cold drawing technology. The carbon steel pipes on the market are divided into high, medium and low grades according to the different carbon content, with different types, and different properties and application ranges.
High carbon steel pipe has the highest carbon content, generally greater than 0.6%, so high carbon steel pipe is generally not used for industrial production. Medium carbon steel pipes are generally 0.25 to 0.6 percent, with moderate hardness and wide applications. The carbon content of low carbon steel pipe is less than 0.25%, which is also common in industrial applications.
