ASTM A556 Carbon Steel Seamless Pipe
GNEE is one of the pioneers in providing ASTM A556 Cold Drawn Seamless Tubes, so you can choose the right pipes and get the evaluation you want at the best price.
ASME SA556 is a general standard specification for seamless cold-drawn carbon steel feedwater heater tubes. It covers seamless cold-drawn carbon steel pipes with minimum wall thickness, including steel pipes bent into U-shaped tubes. The specific grade of A556 carbon steel pipe depends on the application requirements and the required mechanical properties, and is divided into three grades: A2, B2, C2, among which B2 and C2 are commonly used.
ASTM A556 seamless pipes are used to make water-cooled walls of power plant boilers, which can effectively eliminate the steam film on the inner wall of the steel pipe and improve the thermal efficiency of the furnace wall.
