BOILER TUBE GRADES CARBON STEEL SA178 Carbon steels show mild corrosion resistance and fair strength up to 1000F. However, their usage above 800F must take into account the susceptibility to graphitization. Graphitization has not been a significant problem in thicknesses encountered in boiler tubing. Use of heavy section pipe above 800F, however, is not recommended. […]Learn More
The ASME Consensus for Industrial Boilers (see Chapter 13) specifies maximum levels of contaminants for corrosion and deposition control in boiler systems. The consensus is that feedwater oxygen, iron, and copper content should be very low (e.g., less than 7 ppb oxygen, 20 ppb iron, and 15 ppb copper for a 900 psig boiler) and that pH should be maintained between 8.5 and 9.5 for system corrosion protection.Learn More
