Technical requirements and applications of welded copper-nickel pipes according to the ASTM B467 standard
This specification defines the technical regulations and manufacturing standards for welded pipes made of copper-nickel alloys used in the mechanical engineering and energy sectors. EV Group China supplies rolled metal products that fully comply with these requirements, ensuring high corrosion resistance and operational reliability of equipment.
| Alloy Designation (UNS) | Metal Type |
|---|---|
| C70600 | Copper-Nickel 90-10 |
| C70620 | Copper-Nickel 90-10 (welded version) |
| C71500 | Copper-Nickel 70-30 |
| C71520 | Copper-Nickel 70-30 (welded version) |
EV Group China’s regulatory documentation takes into account both the American system of measurement and the International System of Units (SI), the values for which are indicated in square brackets. It is important to note that these systems are not interchangeable: to ensure the accuracy of engineering calculations and compliance with design tolerances, it is necessary to use a single system of measurement specified in the specific order documentation.
