ASTM A106 Gr. B Seamless Pipes

ASTM A106 Grade B Seamless Pipe is a specification and grade for high-temperature, high-pressure carbon steel pipes. The A106 Grade B Seamless Pipe is used in applications where hot gases and fluids are transported at elevated temperatures.
This A106 Seamless carbon steel pipe is ideal for oil and gas refineries, power plants, petrochemical plants, boilers, and ships.

The A106 Grade B range is completely seamless with wall thicknesses varying from schedule 40 to schedule 160 with weights ranging from Standard, Xtra Strong to Xtra-Xtra strong. All of the A106 Grade B pipes are recyclable, complete with Plain Ends.

A106 Seamless steel Pipe Specifications

ASTM A106 and ASME SA106 seamless pressure 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.
