One of the most common questions we get from buyers is a practical one: once the order is confirmed, how does a piece of equipment this size actually get from China to our project site?
It's a fair thing to ask. CNG tube skids are high-pressure vessels — they're not standard freight. The transport setup directly affects your project timeline and landed cost. Here's how it works.
1. How It Gets There: Sea + Land, Both Standardized
Huayan's CNG tube skids are built on standard 20ft or 40ft container frames. That's not just a size decision — it means the equipment is designed to move through the global freight system without special handling.
Stage | Method | Notes |
Export shipment | Standard container vessel (sea freight) | 20ft/40ft frames match ISO container dimensions exactly — no special-charter vessels needed |
Port discharge | Standard port crane (lifting) | The skid supports standard lifting operations; routine port equipment handles it |
Final delivery | Road trailer (inland transport) | Once off the vessel, the skid can be towed directly to site by standard truck — industrial park, mining area, city outskirts, all manageable |
The whole chain runs through standard freight channels. Import documentation is straightforward — no special permits required just for the transport method.
2. 20ft vs 40ft: It's About Capacity and Use Case, Not Just Size
The frame size determines your storage capacity and how you'll deploy the skid in the field.
20ft Frame | 40ft Frame | |
Typical capacity | ~4,640 Nm³ (10 tubes) | ~7,718–9,260 Nm³ (16 tubes) |
Tube count | 10 tubes | 16 tubes |
Best for | Daughter stations, space-constrained sites, lower-volume projects | Fixed refueling stations, industrial supply, high-volume trunk line projects |
Transport flexibility | More mobile, suited for rotation between multiple sites | Higher single-trip volume, fewer refill runs needed |
Port handling | Standard port equipment | Standard port equipment |
If your project runs on a daughter station model — pulling gas from a mother station and distributing to multiple points — the 20ft frame gives you more flexibility to rotate equipment. If you're running a fixed station with consistent high demand, the 40ft frame covers more volume per delivery, which lowers your operating cost over time.
3. Available Specifications
Current standard configurations from Huayan — all customizable based on site conditions:
Frame Size | Tube Count | Gas Capacity (Nm³) | Working Pressure |
20ft | 10 tubes | 4,640 Nm³ | 250 bar (25 MPa) |
20ft / 40ft | 12 tubes | 5,200–5,568 Nm³ | 250 bar (25 MPa) |
40ft | 16 tubes | 7,718–9,260 Nm³ | 250 bar (25 MPa) |
All units are built with seamless steel cylinders and containerized frame design. Cylinders are manufactured to ISO 11120. The system holds ISO and ASME certifications and supports both CNG and compressed hydrogen (H₂) service.
Standard container frame → ships on any container vessel. Supports lifting and trailer towing → ready to deploy on arrival. 20ft for flexible rotation, 40ft for high-volume fixed stations.
If you're not sure which configuration fits your project, share your daily gas consumption and site dimensions — we can put together a spec recommendation.
