Product Selection Differences for Metric Flanges

When selecting Metric Flanges, there are several key differences to consider:

1. Material: Metric flanges are available in various materials such as carbon steel, stainless steel, aluminum, and other alloys. The material choice will depend on factors such as the application, pressure rating, temperature, and corrosion resistance requirements.

2. Pressure Rating: Metric flanges come in different pressure ratings, ranging from PN6 to PN100, with higher pressure ratings suitable for more demanding applications. It is crucial to select a flange with the appropriate pressure rating to ensure system integrity and safety.

3. Flange Type: There are several types of metric flanges, including welding neck, slip-on, socket weld, blind, lap joint, and threaded flanges. The flange type will depend on the piping system design and installation requirements.

4. Size and Dimensions: Metric flanges are available in different sizes, typically ranging from DN10 to DN1200. It is essential to select the right flange size to ensure proper fit and compatibility with other system components.

5. Standard Compliance: Metric flanges are manufactured according to various standards such as DIN, EN, and ISO. Ensure that the flanges you select comply with the relevant standards to guarantee quality and performance.

6. Surface Finish: Flange surface finish plays a role in sealing effectiveness and corrosion resistance. Common surface finishes include raised face, flat face, and ring-type joint facing. Choose the appropriate surface finish based on the application requirements.

7. Additional Features: Consider any additional features or customization options required, such as special coatings for enhanced corrosion resistance, anti-vibration properties, or specific gasket compatibility.

By carefully evaluating these key differences and understanding your specific application requirements, you can select the most suitable metric flanges for your project or system.
