The term carbon steel pipe can be used to describe a wide range of metal tubular goods whose main alloying element is carbon in a range of 0.12%-2%.

ASTM A106 seamless pressure pipe (also known as ASME SA106 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.
The term carbon steel pipe can be used to describe a wide range of metal tubular goods whose main alloying element is carbon in a range of 0.12%-2%.
ASTM A106 pipe is a seamless carbon steel alloy pipe intended for high temperature and high-pressure applications.
ASTM Standards can be purchased as a digital library subscription or individually from ASTM and other qualified standards providers.
Bimetal Clad Pipe and Bend are cast with mold vanishing vacuum suction casting cladding process.
Because they have different scope and specify different type of pipe, then the manufacturing process and required quality control test and inspection will be different to each other.
