What is DIN17175 Steel Pipe?
DIN 17175 steel pipe is designed for elevated temperature purposes, Bestar Steel supplies the following steel grades: St35.8, St45.8, 15Mo3, 13CrMo44, 10CrMo910. DIN 17175 seamless steel pipes are widely used in heat exchange appliances. The pipes under DIN 17175 steel pipe are manufactured from carbon and low-alloy steel grades which are resistant to loads under high pressure and temperatures. They are used for the construction of power engineering appliances such as boilers, heating coils, stoves, heaters, and heat exchanger tubes.
DIN 17175 seamless steel pipes are used for boiler installations, high-pressure pipelines and tank construction, and special machinery for both high-temperature and high-pressure devices(Above 450°high temperature).
