Stainless Steel Bulkhead Union
Stainless Steel Bulkhead Union
A Stainless Steel Bulkhead Union is a specialized instrumentation fitting designed to connect two tubes through a panel, wall, or bulkhead while maintaining a secure, leak-proof seal. These fittings are widely used in instrumentation systems, hydraulic systems, and high-pressure industrial pipelines where tubing must pass through equipment enclosures or partitions.
Bulkhead unions are engineered to provide high strength, corrosion resistance, and reliable performance in demanding environments. Oil and gas, petrochemical, power generation, semiconductor, chemical processing, and maritime engineering are among the industries that frequently use them.
Manufactured with precision machining and high-grade stainless steel, bulkhead unions ensure long service life, easy installation, and excellent pressure handling capability.
Types of Stainless Steel Bulkhead Union
Bulkhead unions are available in several configurations and connection styles to meet different industrial requirements.
Straight Bulkhead Union
The Straight Bulkhead Union is the most commonly used configuration. It connects two tubes in a straight line through a panel or wall.
Key Features
- Minimum pressure loss and a straight flow path
- Suitable for instrumentation panels and control systems
- High pressure and vibration resistance
- Small and dependable design
Typical Applications
- Panels for process control
- Systems that use hydraulics
- Gas distribution systems
Elbow Bulkhead Union
An Elbow Bulkhead Union provides a 90-degree change in flow direction while passing through a bulkhead or panel.
Key Features
- Space-saving installation
- Reduces the need for additional fittings
- Efficient routing in compact systems
Typical Applications
- Chemical plants
- Hydraulic apparatus
- Industrial piping systems
Tee Bulkhead Union
A Tee Bulkhead Union allows three tubes to be connected, creating a branching flow path within the system.
Key Features
- Enables fluid or gas distribution
- Reduces system complexity
- Strong and leak-tight connections
Typical Applications
- Gas sampling systems
- Analytical instrumentation
- Process control systems
Cross Bulkhead Union
The Cross Bulkhead Union connects four tubing lines through a panel, enabling multi-directional flow.
Key Features
- Perfect for intricate instrumentation systems
- Supports multiple connections
- Improves system efficiency
Typical Applications
- Industrial distribution systems
- Process instrumentation networks
Types by Connection Method
Compression Bulkhead Union
Compression-type bulkhead unions are widely used in instrumentation and high-pressure tubing systems. A twin ferrule mechanism is used in these fittings to produce a tight, leak-proof seal.
Advantages
- Easy installation and removal
- Dependable Sealing Results
- Excellent vibration resistance
Threaded Bulkhead Union
Threaded bulkhead unions are designed for systems that require threaded pipe connections.
Common Thread Types
- NPT (National Pipe Thread)
- BSPT (British Standard Pipe Taper)
- BSPP (British Standard Pipe Parallel)
Advantages
- Strong mechanical connection
- Suitable for industrial fluid transfer systems
- Easy compatibility with threaded pipes
Welded Bulkhead Union
Welded bulkhead unions are used in applications where a permanent and extremely strong connection is required.
Advantages
- High structural strength
- Suitable for high-temperature systems
- Eliminates leakage risk in critical applications
Common Applications
- Oil & gas pipelines
- Power plants
- Chemical processing facilities
