Many people didn’t know the difference between ASME SA106C seamless pipe and 20G seamless pipe. Katalor as a famous steel supplier in China, we have ASME SA106C seamless pipe with good quality, because we have a strict quality control system in ASME SA106C seamless pipe.
20G steel pipe is GB/5310 national standard steel number (foreign corresponding grade: Germany st45.8, Japan STB42, US SA106B), which is the most commonly used steel for boiler steel pipe. Its chemical composition and mechanical properties are basically the same as those of 20 plates. The steel has certain normal temperature and medium-high temperature strength, low carbon content, good plasticity and toughness, and good cold-hot forming and welding performance.
ASME SA106C seamless pipe is the steel number in the ASME SA106 standard, “SA” is the mark of ASME steel material, “106” indicates the specification sequence number, and “C” indicates the strength grade. ASME SA106C seamless pipe is used for high-temperature large-diameter boilers and superheaters, carbon-manganese steel pipe.
The ASME SA106C seamless pipe chemical composition is simple, similar to 20G carbon steel, but the carbon and manganese content is higher. So that its yield strength is about 12% higher than 20G, and the plastic and toughness are not bad. The steel production process is simple, hot and cold processing performance. It can replace the 20G manufacturing header (economizer, water wall, low temperature superheater and reheater header), which can reduce the wall thickness by about 10%, which can save material cost and reduce Welding workload and improve the stress difference at the start of the header.
In the fact, ASME SA106C seamless pipe has lots of advantages in the use. We have ASME SA106C seamless pipe with high quality, best service and low price. So if you have any need in ASME SA106C seamless pipe, please contact us. We are glad to help you sovle all problems.
