EN 1092-1 Type 13 Flange

Description

Product Description EN 1092-1 Type 13

EN 1092-1 Type 13 refers to a specific type of threaded flange used in piping systems. These flanges are typically used in industrial applications, especially for connecting pipes to equipment. They adhere to the European Standard EN 1092-1, which specifies requirements for flanges and their associated components. Type 13 Refers to a flange design that typically features a flat face with no raised area. It is commonly used where the connection surface needs to be flat and uniform to allow a reliable seal. EN 1092-1 Type 13 flanges are designed with bolt holes that align with the bolts for easy installation, ensuring a secure and leak-proof connection.

Material

• Carbon Steel (e.g., ASTM A105)
• Alloy Steel (e.g., ASTM A182)
• Stainless Steel (e.g., ASTM A312, A351)
• Duplex Stainless Steel (e.g., 2205)
• Nickel Alloys (e.g., Inconel, Monel)
• Copper Alloys and others.

Application

• Pipelines and Piping Systems: Ideal for systems where a temporary or easily disassembled connection is required.
• Water Treatment Plants: Due to their ease of installation and disassembly.
• Chemical Processing: In systems where corrosion resistance is important.
• Petrochemical: For systems requiring high pressure handling.
• HVAC: Threaded flanges are commonly used in air and gas piping systems.
