DIN 17175 Seamless Steel Pipe Description
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.
Scope of Application
DIN 17175 alloy steel pipe adopts heat-resistant pipe, which is suitable for high-pressure environment below 600 ℃. The application scope includes the construction of boilers, pipelines, pressure vessels and equipment.
