Component Specifications

Definition
A specialized threaded or flanged connection point on an inert gas supply manifold designed to securely mount a pressure gauge, allowing real-time monitoring of gas pressure within the system to ensure safe and efficient operation.
Working Principle
Provides a sealed interface between the manifold's internal gas flow and the pressure gauge. The port transmits pressure from the gas stream to the gauge's sensing element (typically a Bourdon tube, diaphragm, or capsule), which converts pressure into mechanical movement displayed on the gauge dial.
Materials
Stainless steel (AISI 316L/304), brass (C36000), or carbon steel with corrosion-resistant coatings; compatible with inert gases like nitrogen, argon, or helium.
Technical Parameters
  • Port Size 1/4" to 1/2" NPT common
  • Thread Type NPT, BSP, or metric threads (e.g., G1/4, M20x1.5)
  • Sealing Method O-ring, gasket, or thread sealant
  • Pressure Rating Up to 3000 psi (207 bar)
  • Temperature Range -20°C to 150°C
  • Connection Orientation Vertical, horizontal, or angled
Standards
ISO 1179, DIN 3852, ASME B1.20.1

Engineering Analysis

Risks & Mitigation
  • Leakage due to improper sealing
  • Thread damage during installation
  • Corrosion from incompatible materials
  • Overpressure if gauge fails
FMEA Triads
Trigger: Incorrect thread sealing or overtightening
Failure: Gas leakage leading to pressure loss or safety hazards
Mitigation: Use proper sealants (e.g., PTFE tape), follow torque specifications, and conduct leak tests
Trigger: Material incompatibility with inert gas or environment
Failure: Corrosion or contamination of gas supply
Mitigation: Select materials like stainless steel 316L for high purity, and validate compatibility charts
