Product Selection Differences for Raised Face Flanges

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

  1. Material: Raised Face Flanges can be made from various materials, such as stainless steel, carbon steel, alloy steel, and other metals. The material chosen should align with the specific application requirements, including factors like temperature, pressure, and corrosion resistance.

  2. Pressure Rating: Raised Face Flanges come in different pressure ratings to accommodate varying operating conditions. It is crucial to select a flange with a pressure rating that matches or exceeds the requirements of the system where it will be installed.

  3. Size: Raised Face Flanges are available in different sizes, ranging from ½ inch to several feet in diameter. The size of the flange should match the size of the pipes or fittings it will be connecting.

  4. Face Finish: Raised Face Flanges have a raised surface around the bore hole that provides a sealing surface. The face finish can vary, with options like serrated, smooth, or spiral finish. The selection of face finish should be based on the application requirements for effective sealing.

  5. Standards and Specifications: Raised Face Flanges must conform to specific standards and specifications, such as ASME B16.5 or API 6A. Ensuring that the flanges meet relevant industry standards is essential for compatibility and performance.

  6. Bolt Holes and Bolt Circle Diameter: The number and size of bolt holes on the flange, as well as the bolt circle diameter, are critical considerations for proper installation and alignment with the mating flange.

  7. Application: Consider the specific application requirements, including the type of fluid being conveyed, temperature conditions, and any other unique environmental factors that could impact the performance of the flange.

By carefully evaluating these key differences, you can select the most suitable Raised Face Flange for your specific needs and ensure reliable and efficient operation within your system.
