Price Ranges for Round Bellow Flanges

Round bellow flanges, commonly used in piping systems to accommodate movements and vibrations, can vary in price depending on several factors, including material, size, pressure rating, and manufacturer. Here’s a general breakdown of typical price ranges you might encounter:

1. Materials: Common materials for round bellow flanges include stainless steel, carbon steel, and alloys. Prices vary significantly by material:

   • Stainless Steel: $30 to $500
   • Carbon Steel: $20 to $250
   • Alloy Materials: $50 to $700

2. Sizes: The diameter and thickness of the flange can also impact the price. Larger flanges typically cost more.

   • Small (2-4 inches): $20 to $100
   • Medium (4-10 inches): $50 to $300
   • Large (10+ inches): $150 to $700+

3. Pressure Ratings: Flanges are rated based on their pressure-handling capacity (e.g., ANSI/ASME ratings of 150, 300, 600, etc.), with higher ratings generally costing more.

   • Low Pressure (150 lb): $30 to $150
   • Medium Pressure (300 lb): $50 to $300
   • High Pressure (600 lb and above): $100 to $1,000+

4. Customizations and Features: Special features such as custom sizes, machining, or specific coatings can lead to higher prices.

5. Brand and Manufacturer: Established brands might charge a premium for their products, while lesser-known manufacturers might offer competitive pricing.

It's advisable to check with suppliers or distributors for current pricing and availability, as market conditions can affect costs. Online marketplaces and industrial supply stores can also provide real-time pricing and options.
