Bulkhead Union

A bulkhead union is a fitting used in piping or tubing systems to create a secure and leak-proof connection through a wall or partition. This fitting allows for the passage of fluids or gases from one side of the chamber to the other without compromising the system's integrity. Bulkhead unions are commonly used in various applications, including industrial processes, plumbing, and fluid transfer systems.

Components

Nut: The nut is threaded and used to secure the fitting, typically on both sides of the partition.
Body or Coupling: The body of the bulkhead union contains the internal components necessary for creating secure and leak-proof connections between pipes or tubes on either side of the partition.
Sealing Components: Bulkhead unions often include O-rings, gaskets, or other sealing components to ensure a tight and reliable seal against the section.

Installation

Cutting and Preparing Pipes: Cut the pipes to the desired lengths and prepare the ends for connection.
Making a Hole: Drill or cut a hole through the wall or partition where the bulkhead union will be installed.
Assembling the Bulkhead Union: Slide the nuts over the ends of the pipes, insert the tubes through the hole in the partition, and then thread the nuts onto the fittings on both sides of the chamber.
Tightening: Use appropriate tools to tighten the nuts securely on both sides of the partition, ensuring a leak-proof and stable connection.

Considerations

Material Compatibility: Ensure that the materials of the bulkhead union are compatible with the substances flowing through the piping system.
Application: Consider factors such as pressure, temperature, and the nature of the fluid or gas when selecting a bulkhead union for a specific application.

Types

Male-Female Bulkhead Union: One side of the fitting has external threads (male), and the other has internal lines (female). This type is commonly used when connecting to a threaded component on one side of the partition.
Double Female Bulkhead Union: Both sides of the fitting have internal threads (female). This type is suitable for connecting components with external lines on both sides of the partition.
