N545 and ISO2531 are internationally recognized standards that define the specifications for ductile iron pipes used in water supply and sewerage systems. These standards ensure that the pipes meet specific requirements for material quality, dimensions, mechanical properties, and coatings, making them suitable for various applications.
Product Overview:
Ductile iron pipes compliant with EN545 and ISO2531 standards are designed for the conveyance of potable water, sewage, and other fluids. They are available in various pressure classes, such as K8 and K9, to suit different operational requirements.
Key Features:
Material Excellence: Manufactured from ductile cast iron, these pipes offer superior tensile strength and flexibility compared to traditional gray iron pipes. They are less prone to cracking and can withstand external pressures, making them ideal for diverse installation conditions.
Durability: The pipes are designed to resist corrosion, ensuring a long service life with minimal maintenance. This resistance is achieved through internal cement mortar linings and external coatings, such as zinc-bitumen or epoxy.
Dimensional Compatibility: Designed to match the internal diameter of the pipe, following internal lining, to the nominal diameter, these pipes ensure compatibility with existing systems and ease of installation.
Technical Specifications:
| Nominal Diameter (DN) | Outside Diameter (mm) | Wall Thickness (mm) | K8 Pressure Class (kg/m) | K9 Pressure Class (kg/m) |
|---|---|---|---|---|
| 80 | 98 | 6.0 | 77.0 | 77.0 |
| 100 | 118 | 6.0 | 93.7 | 95.0 |
| 150 | 170 | 6.0 | 138.0 | 144.0 |
| 200 | 222 | 6.3 | 183.0 | 194.0 |
| 300 | 326 | 7.2 | 290.0 | 323.0 |
| 400 | 429 | 8.1 | 433.0 | 482.0 |
| 600 | 635 | 9.9 | 791.0 | 882.0 |
Note:The above dimensions and weights are indicative and may vary based on manufacturer and specific requirements.
Applications:
