Gas Outlet Connection: Temperature Range -40°C to 200°C

Q: What factors determine gas outlet connection selection?

Gas compatibility, pressure rating, temperature range, flow requirements, and connection type compatibility with existing systems.

Q: How often should gas outlet connections be inspected?

Visual inspection monthly, pressure testing every 6-12 months, and complete replacement per manufacturer guidelines or when wear exceeds tolerance limits.

Component Specifications

Definition

A precision-engineered mechanical interface component designed to establish a leak-proof, pressure-rated connection between gas cylinders or generators and downstream piping or equipment. It ensures controlled gas flow while maintaining system integrity under varying pressure conditions.

Working Principle

Utilizes threaded, flanged, or quick-connect mechanical interfaces with sealing elements (gaskets, O-rings) to create a pressure-tight seal. The connection maintains structural integrity through mechanical fastening while allowing controlled gas passage through integrated flow channels.

Materials

Stainless steel (AISI 316L/304), brass (C36000), aluminum alloys (6061-T6), with PTFE or Viton sealing elements. Material selection based on gas compatibility, pressure rating, and environmental conditions.

Technical Parameters

Parameter	Typical range	Notes & selection driver
Leak Rate	<1x10^-9 mbar·L/s (helium)
Port Size	1/4" to 2" NPT
Surface Finish	Ra ≤ 0.8 μm for sealing surfaces
Connection Type	Threaded (NPT, BSP), Flanged, Quick-Connect
Pressure Rating	150-3000 PSI
Temperature Range	-40°C to 200°C
