1. Cleaning before Packing
Before packaging, each Vacuum Insulated Pipe (VIP)—a vital part of vacuum insulation cryogenic systems—undergoes a final, thorough cleaning to ensure maximum cleanliness, reliability, and performance.
1. Outer Surface Cleaning – The VIP’s exterior is wiped with a water- and oil-free cleaning agent to prevent contamination that could affect cryogenic equipment.
2. Inner Pipe Cleaning – The interior is cleaned through a precise process: purged with a high-power fan, purged with dry pure nitrogen, brushed with a precision cleaning tool, and purged again with dry nitrogen.
3. Sealing & Nitrogen Filling – After cleaning, both ends are sealed with rubber caps and kept nitrogen-filled to maintain cleanliness and prevent moisture ingress during shipping and storage.
2. Pipe Packing
For maximum protection, we apply a two-layer packaging system for every Vacuum Insulated Pipe (VIP) before shipment.
First Layer – Moisture Barrier Protection
Each Vacuum Insulated Pipe is completely sealed with a high-quality protective film, creating a moisture-proof barrier that safeguards the integrity of the vacuum insulation cryogenic system during storage and transport.
Second Layer – Impact & Surface Protection
The pipe is then fully wrapped in heavy-duty packing cloth to shield it from dust, scratches, and minor impacts, ensuring the cryogenic equipment arrives in pristine condition, ready for installation in cryogenic piping systems, Vacuum Insulated Hoses (VIHs), or Vacuum Insulated Valves.
This meticulous packaging process guarantees that every VIP maintains its cleanliness, vacuum performance, and durability until it reaches your facility.
3. Secure Placement on Heavy-Duty Metal Shelves
During export transportation, Vacuum Insulated Pipes (VIPs) may undergo multiple transfers, hoisting operations, and long-distance handling—making secure packaging and support absolutely critical.
- Reinforced Steel Structure – Each metal shelf is constructed from high-strength steel with extra-thick walls, ensuring maximum stability and load-bearing capacity for heavy cryogenic piping systems.
- Custom Support Brackets – Multiple brackets are precisely positioned to match each VIP’s dimensions, preventing movement during transit.
- U-Clamps with Rubber Padding – VIPs are firmly secured using heavy-duty U-clamps, with rubber pads placed between the pipe and clamp to absorb vibration, prevent surface damage, and maintain the integrity of the vacuum insulation cryogenic system.
This robust support system ensures that every Vacuum Insulated Pipe arrives safely, maintaining its precision engineering and performance for demanding cryogenic equipment applications.
4. Heavy-Duty Metal Shelf for Maximum Protection
Every Vacuum Insulated Pipe (VIP) shipment is secured in a custom-engineered metal shelf designed to withstand the rigors of international transportation.
1. Exceptional Strength – Each metal shelf is built from reinforced steel with a net weight of no less than 2 tons (for example: 11m × 2.2m × 2.2m), ensuring it is strong enough to handle heavy cryogenic piping systems without deformation or damage.
2. Optimized Dimensions for Global Shipping – Standard sizes range from 8–11 meters in length, 2.2 meters in width, and 2.2 meters in height, perfectly matching the dimensions of a 40-foot open-top shipping container. With integrated lifting lugs, shelves can be safely hoisted directly into containers at the dock.
3. Compliance with International Shipping Standards – Each shipment is marked with the required shipping labels and export packaging marks to meet logistics regulations.
4. Inspection-Ready Design – A bolted, sealable observation window is built into the shelf, allowing customs inspection without disturbing the secure placement of the VIPs.
