2. Governing DIN Material and Product Standards
This product family is defined by a series of interlinked DIN standards, each covering a specific aspect from material to final product requirements.
Table 1: Governing DIN Standards for Nickel Alloy Pipes
| DIN Standard | Standard Title / Focus | Key Parameters Defined |
|---|---|---|
| DIN 17744 | Seamless tubes of nickel and nickel alloys - Technical delivery conditions | This is the overarching product standard. It defines the general technical delivery conditions, including ordering information, manufacturing process, requirements for dimensions, mechanical properties, leak-tightness, surface condition, and inspection procedures for all seamless nickel alloy tubes. |
| DIN 17750 | Wrought nickel and nickel alloys - Sheet, strip, bar, wire and forgings | This standard specifies the chemical composition and material properties for various wrought forms of nickel alloys. It is often referenced to define the base material from which the pipe is made. |
| DIN 17751 | Seamless tubes of nickel and nickel alloys - Dimensions and tolerances | This standard provides the precise dimensional tables and permissible tolerances for outer diameter, wall thickness, and length of seamless nickel alloy pipes. It ensures interchangeability and proper fit for installation. |
3. Common Nickel Alloy Materials and Their Properties
Pipes conforming to these DIN standards are typically made from well-established nickel alloys, chosen for their specific resistance properties.
Table 2: Typical Nickel Alloys for Oil & Gas Transportation
| Material Number (Werkstoff Nr.) | Common Trade Name / Alloy | Key Characteristics for Oil & Gas |
|---|---|---|
| 2.4066 | Nickel 201 (99.9% Ni) | Excellent resistance to caustic alkalis and high-temperature corrosion. Good mechanical properties. |
| 2.4816 | Alloy 600 (Ni-Cr-Fe) | Good resistance to oxidation and corrosion by a wide variety of environments. Used in high-temperature processing. |
| 2.4851 | Alloy 625 (Ni-Cr-Mo-Nb) | Excellent all-round performer. Superior resistance to pitting, crevice corrosion, and high-strength due to niobium strengthening. Ideal for sour service and seawater. |
| 2.4668 | Alloy C-276 (Ni-Mo-Cr) | Exceptional resistance to severe corrosive conditions, including wet chlorine gas and mixed acids. |
| 2.4360 | CuNi30Mn1Fe | A copper-nickel alloy with excellent resistance to seawater and brine corrosion, used in offshore cooling and transport systems. |
