Differences Between ISO 6164 and JIS B 2291 Standards: How to Choose the Right Flange?
Hydraulic flanges are critical components in industrial systems, providing secure and leak-proof connections. Among the most commonly used standards are ISO 6164 and JIS B 2291. While both are reliable, each serves distinct purposes and suits specific applications.
This article highlights the key differences between these two standards and offers guidance on how to choose the right flange for your hydraulic system.
1. Overview of ISO 6164 and JIS B 2291 Standards
ISO 6164 and JIS B 2291 define the design, dimensions, and specifications for hydraulic flanges.
• ISO 6164
• Developed by the International Organization for Standardization (ISO).
• Focuses on square flanges for high-pressure hydraulic systems (up to 400 bar).
• Widely used in Europe and internationally for heavy-duty applications.
• JIS B 2291
• A Japanese Industrial Standard (JIS) for square hydraulic flanges.
• Designed for medium- to high-pressure systems (up to 300 bar).
• Commonly used in Asia, especially in industries where JIS standards dominate.
2. Key Differences Between ISO 6164 and JIS B 2291
Aspect | ISO 6164 | JIS B 2291 |
Pressure Rating | Up to 400 bar | Up to 300 bar |
Application Scope | Heavy-duty systems, global industries | Medium-duty systems, Asian industries |
Material Standards | Typically carbon steel or stainless steel | Similar materials, but regional variations exist |
Sealing Mechanism | Advanced O-ring grooves for high pressure | Standard sealing designs |
Dimensions | International standard, globally unified | Regionally focused, metric-based |
3. When to Use ISO 6164 Flanges?
ISO 6164 flanges are ideal for:
1. High-Pressure Systems
• Designed to handle pressures up to 400 bar, making them suitable for heavy-duty applications.
2. Global Operations
• Preferred by companies with international operations due to their global standardization.
3. Demanding Environments
• Common in industries like oil and gas, mining, and marine equipment, where reliability under extreme conditions is critical.
4. When to Use JIS B 2291 Flanges?
JIS B 2291 flanges are best suited for:
1. Regional Applications
• Ideal for businesses operating primarily in Asia or using JIS-compliant equipment.
2. Medium-Pressure Systems
• With a pressure rating of up to 300 bar, they are suitable for medium-duty hydraulic systems.
3. Cost-Sensitive Projects
• Often more cost-effective for applications not requiring the high-pressure capabilities of ISO 6164 flanges.
5. How to Choose the Right Flange?
Consider the following factors when deciding between ISO 6164 and JIS B 2291 flanges:
1. Operating Pressure
• Choose ISO 6164 for systems exceeding 300 bar.
2. Regional Standards
• Opt for JIS B 2291 if your machinery follows JIS specifications or operates in Asian markets.
3. Application Requirements
• For high-pressure, heavy-duty applications, ISO 6164 is the better choice.
• For cost-effective medium-pressure systems, JIS B 2291 flanges are more suitable.
4. Compatibility
• Ensure the flange standard matches the existing components in your system.
5. Industry Norms
• Consult industry-specific regulations or client preferences to ensure compliance.
