More info

The component you're asking about is a Stainless Steel Flexible Pigtail or High-Pressure Transfer Hose Assembly used to connect high-pressure cylinders of gases like Argon ( $text{Ar}$ ) or Oxygen ( $text{O}_2$ ) to industrial regulators or manifold systems.

This assembly is characterized by its stainless steel construction for strength and safety, and the integrated pressure gauge to monitor the cylinder contents.

Key Specifications and Features

Argon and Oxygen are classified as permanent gases or compressed gases. They are stored at extremely high pressure, but remain in the gas phase at standard temperatures.

1. Pressure Rating and Construction

Cylinder Pressure: Full industrial cylinders of Argon and Oxygen are typically pressurized to:
- $mathbf{200 text{ Bar}}$ $approx 2,900 text{ PSI}$ , or
- $mathbf{300 text{ Bar}}$ $approx 4,350 text{ PSI}$ for high-capacity cylinders.
Hose Working Pressure: The stainless steel pigtail must be rated to handle these high pressures with a significant safety factor. They are generally rated for a minimum of 200 Bar and often up to 400 Bar or 500 Bar to ensure safety.
Material:
- Core: Corrugated Stainless Steel (SS) tubing $text{SS } 316 text{L}$ provides the necessary pressure integrity and chemical compatibility.
- Braid: An external SS braid $text{SS } 304$ provides robust reinforcement against kinking, abrasion, and internal pressure expansion.
