Complete Guide to Flange Standards: PN16, PN40, ANSI, JIS, and DIN
Flanges are essential components in industrial piping systems, serving as connectors between pipes, valves, pumps, and other equipment. To ensure safe and efficient installation, flanges are manufactured based on international standards.
The most commonly used flange standards include PN16, PN40, ANSI, JIS, and DIN. Let’s explore each of these standards, their applications, and how to choose the right one for your project.
1. PN16 Flange
Origin: Europe
Pressure Rating: Up to 16 bar (≈16 kg/cm²)
Applications: Water systems, HVAC, food industry, and medium-pressure installations.
Advantages: Cost-effective, suitable for low to medium pressure piping.
2. PN40 Flange
Origin: Europe
Pressure Rating: Up to 40 bar (≈40 kg/cm²)
Applications: Oil & gas, petrochemical plants, and high-pressure power generation systems.
Advantages: Thicker material, designed for high pressure and extreme temperature environments.
3. ANSI Flange (American National Standards Institute)
Origin: United States
Pressure Classes: Class 150, 300, 600, 900, 1500, up to 2500
Applications: Widely used in global industries, including oil & gas, power plants, and large-scale construction.
Advantages: Internationally recognized, versatile, and compatible across multiple industries.
4. JIS Flange (Japanese Industrial Standards)
Origin: Japan
Pressure Classes: JIS 5K, 10K, 16K, 20K, 30K
Applications: Common in Asia for water systems, boilers, and manufacturing facilities.
Advantages: Practical, economical, and widely available across Asian markets.
5. DIN Flange (Deutsches Institut für Normung)
Origin: Germany/Europe
Pressure Classes: DIN PN6, PN10, PN16, PN25, PN40, up to PN100
Applications: Infrastructure, chemical industries, and power plants.
Advantages: High precision, durable materials, trusted in European projects.
