High Precision Cold Drawn Seamless Steel Tube Carbon Steel Pipes
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.
