Starting Information

• Determine basic routing of the cryogenic piping system, including: bulk tank location, equipment location, and piping elevation
• Provide an isometric sketch to clarify piping configuration. Quality Cryogenics will then provide isometric Autocad drawings with dimensions for your verification. Quality Cryogenics can provide any assistance needed in determining layout or dimensions.
• Size the pipe and components based on current flow rates, while providing for any future expansion. Consult Quality Cryogenics for assistance.
• Identify application to help Quality Cryogenics determine the components needed to maximize your piping system's efficiency.
• Highlight any installation points of interest, such as wall penetrations, close quarters, existing fixtures, drop ceilings, etc.
• Determine maximum spool lengths based on access for pipe and assembly.

Typical Attributes for your VJ Pipe System

• Bayonet couplings for ease of installation
• Field welded couplings for higher pressures and reduced heat leak.
• Typically 1" to 2" headers for main or high usage branch runs
• Typically 1/2" or 1" drops to equipment
• Vacuum jacketed in-line valves for branch isolation during shutdown or repair .
• System relief valve for line safety .
• Vacuum Gauge Tubes (DV-6R) for monitoring vacuum level of VJ Pipe
• Internal gas traps to prevent frosting of end connections when not in use
• Mechanical keep-cold device to keep the main header cold and liquid on demand at use points
• Capped bayonet or field joint coupling for future expansion
• Bronze extended stem cryogenic valves at equipment connections
• Vacuum Jacketed Flexible Pipe for pipe misalignment and equipment vibrations
• External expansion joints for high pressure applications.
