A Stainless Steel (SS) Double Ferrule Bulkhead Union is a tube fitting designed to provide a secure and leak-tight connection through a panel or bulkhead. This type of fitting is particularly useful when tubing needs to pass through a barrier or enclosure while maintaining a reliable fluid connection on both sides

Construction of SS Bulkhead Union

  1. Material: Typically made of stainless steel to provide corrosion resistance, durability, and strength.
  2. Double Ferrule Design: Like other double ferrule fittings, the bulkhead union features two ferrules (compression rings) associated with each end. The front ferrule seals the connection against the fitting body, and the back ferrule provides support and grips onto the tubing.
  3. Bulkhead Design: The fitting is designed with a bulkhead structure, allowing it to pass through a panel or barrier and maintain a secure connection on both sides.
  4. Body: The main body of the bulkhead union is made of stainless steel, ensuring stability and resistance to corrosion.
  5. Threads: The bulkhead union may have external threads on both ends, allowing it to be connected to other fittings or components with matching threads.

Applications of SS Bulkhead Union

SS Double Ferrule Bulkhead Unions are used in various applications where tubing needs to pass through a panel or bulkhead while maintaining a secure and leak-free connection. Common applications include:

  1. Instrumentation Systems: Used in laboratories and industrial settings for passing tubing through panels in instrumentation and control systems.
  2. Process Control: Suitable for use in systems where fluid lines pass through walls or enclosures in manufacturing and processing plants.
  3. Chemical Processing: Applied in chemical processing plants for passing tubing through barriers while maintaining a secure connection.
  4. Oil and Gas: Used in hydraulic and pneumatic systems within the oil and gas industry for passing tubing through equipment enclosures.
  5. General Plumbing: Suitable for various plumbing applications where tubing needs to pass through walls or partitions.

Salient Features of SS Bulkhead Union

  1. Leak Resistance: The double ferrule design ensures a reliable and leak-tight seal, preventing fluid from escaping the connection.
  2. Pressure and Temperature Resistance: Stainless steel construction allows the bulkhead union to withstand high-pressure and high-temperature conditions.
  3. Corrosion Resistance: Stainless steel provides excellent resistance to corrosion, making these fittings suitable for use with corrosive fluids.
  4. Reusability: The design allows for multiple assembly and disassembly cycles without compromising the integrity of the connection.

Easy Installation: Typically, these bulkhead unions are designed for easy installation, requiring simple tools for assembly

When using SS Double Ferrule Bulkhead Unions, it’s crucial to follow proper installation procedures, ensure compatibility with tubing and other components, and consider factors such as pressure, temperature, and the nature of the fluids being conveyed. Regular inspection and maintenance are also recommended to ensure the continued reliability of the connections.
