DIN 17175 is suitable for seamless pipes and is used in the construction of boilers, pipelines, pressure vessels and equipment. The maximum temperature can reach 600 ℃. At the same time, under high pressure, the total stress and related fouling conditions can increase or decrease the temperature limit.
