Seamless carbon steel tubing or piping, also referred to as drawn piping starts with a solid bar or block of carbon steel. The piece of carbon steel is then put through a process of drilling, extrusion, or oxygen lance to create a hollow pipe. Once the tubing is hollow it is then placed through a die and mandrel phase to create a larger interior diameter providing various sizes of seamless carbon steel tubing.
