DIN 17175 is specifically engineered for applications at elevated temperatures, and CG Steel provides a range of steel grades under this standard, including St35.8, St45.8, 15Mo3, 13CrMo44, and 10CrMo910. These seamless steel pipes find extensive utility in heat exchange equipment. Manufactured from carbon and low-alloy steel grades, in line with DIN 17175, these pipes exhibit resilience to high-pressure and high-temperature conditions. They are instrumental in constructing power engineering appliances like boilers, heating coils, stoves, heaters, and heat exchanger tubes.
DIN 17175 seamless steel pipes serve various purposes, including boiler installations, high-pressure pipelines, tank construction, and specialized machinery designed for both high temperature and high-pressure applications (above 450°C). With expertise in boiler and pressure steel tubes, CG Steel is well-equipped to provide you with DIN 17175 steel pipes covering all grades and dimensions.
