Header Body/Shell: Temperature Range -20°C to 200°C

Component Specifications

Definition

The distribution header body/shell is a critical pressure vessel component in fluid distribution systems that serves as the primary containment structure for distributing liquids or gases to multiple outlets. It provides structural integrity, pressure containment, and precise flow channeling while maintaining consistent pressure and flow characteristics across all distribution branches. This component typically features multiple inlet/outlet ports, internal baffles or flow dividers, and mounting interfaces for integration with piping systems.

Working Principle

The header body/shell operates on fluid dynamics principles where pressurized fluid enters through a primary inlet and is distributed evenly to multiple outlet ports. Internal geometry and flow channels are designed to minimize pressure drop, prevent turbulence, and ensure uniform flow distribution. The shell withstands internal pressure through its structural design while maintaining precise dimensional stability to ensure proper sealing and alignment with connected components.

Materials

Carbon steel (ASTM A106 Grade B), Stainless steel (304/316L), Duplex stainless steel (2205), Aluminum alloys (6061-T6), Pressure vessel quality plates with material certifications

Frequently Asked Questions

What is the primary function of a distribution header body/shell?

The primary function is to provide structural containment and precise flow distribution of fluids to multiple outlets while maintaining pressure integrity and minimizing flow disturbances.

How do you select materials for header bodies?

Material selection depends on fluid compatibility, pressure/temperature requirements, corrosion resistance needs, and industry standards - common choices include carbon steel for general applications and stainless steel for corrosive environments.

What maintenance is required for header shells?

Regular inspection for corrosion, pressure testing, gasket replacement, and cleaning of internal passages to prevent buildup that could affect flow distribution.
