DIN 1629 seamless steel pipes

DIN 1629 is a German standard that specifies the requirements for seamless circular tubes made of non-alloy steel. These pipes are primarily used for general structural purposes and mechanical engineering applications. Unlike other standards that focus on high-temperature or high-pressure applications, DIN 1629 pipes are designed for use in moderate conditions where high strength and durability are still required.

Key Features of DIN 1629 Seamless Steel Pipes

Material Composition:

Non-Alloy Steel: Composed primarily of iron with a small amount of carbon and other elements within specific limits to achieve desired mechanical properties.

Grades: Common grades include St37.0, St44.0, and St52.0, each offering varying levels of tensile strength and mechanical properties suitable for different structural applications.

Standards and Specifications:

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

Mechanical Properties: Includes requirements for tensile strength, yield strength, and elongation to ensure the pipes meet the necessary performance criteria for structural applications.

Testing: Pipes are subjected to various tests, including hydrostatic testing, tensile testing, and non-destructive testing (NDT), to ensure they comply with the specified standards.

Size Specifications

Outer Dimensions: Generally range from 21.3 mm to 660 mm.

Wall Thickness: Varies from 2.0 mm to 40 mm.

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