DIN 17175 seamless steel pipe

DIN 17175 is a German standard that specifies the requirements for seamless steel pipes used in high-temperature service. These pipes are designed for applications where high heat resistance and durability are essential, such as in the construction of boilers, pipelines, pressure vessels, and equipment for service up to 600°C and at simultaneous high pressures.

Key Features of DIN 17175 Seamless Steel Pipes

- Material Composition:

Carbon and Alloy Steel: Typically composed of iron with varying amounts of carbon and other alloying elements such as chromium, molybdenum, and vanadium to enhance heat resistance and mechanical properties.

Grades: Common grades include St35.8, St45.8, 15Mo3, 13CrMo44, and 10CrMo910, each with specific properties suited for different high-temperature applications.

- Standards and Specifications:

Dimensions and Tolerances: The standard specifies outer diameter, wall thickness, and permissible tolerances for different pipe sizes.

Mechanical Properties: Includes requirements for tensile strength, yield strength, elongation, and impact resistance to ensure the pipes can withstand high temperatures and pressures.

Testing: Pipes are subjected to various tests such as hydrostatic testing, tensile testing, and non-destructive testing (NDT) to ensure they meet safety and performance standards.

- Size Specifications

Outer Dimensions: Generally range from 10.2 mm to 711 mm.

Wall Thickness: Varies from 1.6 mm to 100 mm.

Length: Available in fixed or random lengths up to 12000 mm, depending on customer requirements.
