Durable High Pressure Boiler Tube , Carbon Steel Seamless Tube ASTM A106 Grade C

Durable High Pressure Boiler Tube , Carbon Steel Seamless Tube ASTM A106 Grade C

With the development of the power station, the working parameters of the boiler have been improved, especially the emergence of subcritical and supercritical boilers, which has a higher requirement for the wall thickness of the boiler tubing.

ASTM A106 Gr C is ASTM A106 steel used for large diameter and high temperature and pressure boiler and Superheater C-Mn steel. Its chemical composition is simple, similar to that of 20G steel, but the content of carbon and manganese is higher, so the yield strength is about 12% higher than that of 20G, and the plasticity and toughness are similar to 20G. Manufacturing header with A106 Gr C instead of 20G (economizer, water cooling wall, low temperature superheater and reheater header) can reduce the wall thickness of about 10%, which can save the cost of materials, but also reduce the workload of welding, improve the heat transfer condition of boiler. It’s working pressure is 6 ~ 13.9MPa and steam temperature is 450~580 degrees.
