A typical air header manifold assembly consists of:
- A single inlet connection
- Multiple outlet ports along the manifold body
- Individual isolation valves on each outlet
- A drain connection for condensate removal
- Optional vented ball valves for pressure relief and safe isolation
Standard configurations range from 2-way to 12-way assemblies, while bespoke engineered air header manifolds can be manufactured according to specific project, plant, or EPC requirements.
Engineered Air Header Manifolds:
Fluidline air header manifolds are manufactured according to customer specifications and application requirements, including:
- Pressure rating requirements
- Material specifications
- Valve configurations
- Outlet quantity and orientation
- Mounting arrangements
- Documentation and inspection requirements
Fluidline treats air header manifolds as engineered distribution assemblies rather than simple fabricated pipework, ensuring alignment with plant quality, testing, and long-term operational requirements.
Standard construction material is stainless steel, with alternative materials available on request for specialised applications.
All stainless steel manifolds are pickled and passivated, followed by shot blasting to improve surface condition, corrosion resistance, and overall finish quality.
Pressure Relief & Valve Configuration
Fluidline air header manifolds are typically supplied with two-piece full-bore vented ball valves as standard.
The vented valve design assists in relieving trapped or back pressure within the manifold system, supporting safer installation, maintenance, and operational procedures within pneumatic instrumentation systems.
Engineering Documentation & Quality Control:
In engineered installations, air header manifolds are expected to meet defined material, fabrication, testing, and documentation requirements in line with plant QA and EPC specifications.
Fluidline’s approach to air header manifolds follows a controlled engineering and quality workflow designed to reduce installation risk, documentation gaps, and long-term maintenance issues.
Documentation packages can include:
- Customer purchase order records
- Internal QCP documentation
- Pressure test certificates with serial number traceability
- Raw material certificates
- Calibration gauge certificates
- Inspection and testing documentation
- Drawings and manufacturing records where required
Documentation packages are aligned with typical EPC, mining, and industrial plant quality requirements.
Applications:
Fluidline air header manifolds are widely used in:
- Instrument air systems
- Pneumatic control systems
- Process control installations
- Mining process plants
- Chemical plants
- Power stations
- Refineries
- Industrial automation systems
Pressure Testing & Inspection
Every Fluidline air header manifold is pressure tested to 12 bar prior to delivery as standard.
Additional testing and inspection services can include:
- NDT testing according to customer specifications
- Dimensional inspection
- Material traceability verification
- Inspection documentation
- Client-specific quality requirements
High-pressure air header manifolds are also available for applications up to 6000 psi.
