Can This Tube Skid Transport Hydrogen? What's the Difference from the CNG Version?

Many customers ask us this question directly when they see our tube skid: "Can this hold hydrogen?" It's a very practical question. While CNG and hydrogen both appear as gases, both require high-pressure storage and transport, and look similar externally, the requirements for the equipment are not exactly the same. This article d   irectly answers those two questions: Can it be used, and what exactly is different?

Can it transport hydrogen? The answer is: Yes.

Huayan's tube skid product line includes specific models designed to support the storage and transport of compressed hydrogen (H₂). The working pressure is 250 bar (25 MPa), and the frame sizes cover standard 20FT and 40FT container specifications. They can be transported by road trailer and support lifting operations, which is basically the same physical operation as a CNG tube skid.

So if you're asking "can this device physically hold hydrogen?", the answer is yes. However, there are a few important points to clarify:

· Hydrogen poses a risk of hydrogen embrittlement to steel. The cylinder material and processing techniques must be specifically treated for hydrogen media.

· Huayan's tube skids use a seamless steel cylinder process and have undergone special treatment for hydrogen medium models to ensure long-term, safe use under high pressure.

· In terms of certification, the products are certified to ISO / ASME / ISO 11120 standards. ISO 11120 is specifically for seamless steel high-pressure cylinders and is one of the core certifications for hydrogen tube skids entering the international market.

What's the difference from the CNG version?

From a product structure perspective, CNG tube skids and hydrogen tube skids are identical in terms of frame design, working pressure, and tube bundle quantity configuration. The core differences lie in the cylinder material processing and cleaning standards for the applicable medium. The table below shows a comparison of the main parameters:

In simple terms: They are highly similar in appearance and usage, with the difference being the internal material processing of the cylinders. This is also why customers must clearly state their medium before placing an order—once the equipment is custom-made for a specific medium, switching to another requires re-evaluation and re-certification.
