What is the Water Volume, Working Pressure, and Gas Storage Capacity of a Tube Trailer?

In the land transportation of compressed natural gas (CNG), the core parameters of a tube trailer directly determine transport efficiency and economic viability. According to the latest information from Huayan, current mainstream CNG tube skid solutions are centered around modular combinations of large-volume cylinders.

Addressing your specific interest, the market primarily utilizes two main cylinder specifications. Based on the detailed product data we've accessed, Huayan's demonstrated mature solutions are built around a core cylinder with an individual water volume of 2,450 liters. These are combined in varying quantities to form a complete CNG Tank Storage system.

For instance, a Tube Bundle Container configured with nine 2,450L cylinders achieves a total water volume of 22.05 cubic meters. Under a working pressure of 25MPa (approx. 250 bar), this standard 40-foot skid can store up to 6,495 Nm³ of natural gas.

For applications demanding higher capacity, a CNG Tube Skid integrating fourteen 2,450L cylinders boasts a total water volume of 39.2 cubic meters. At the same 25MPa working pressure, its total gas storage capacity increases impressively to 10,718 Nm³.

It's also important to note that the working pressure is adaptable. The product information indicates these tube skids typically operate within a pressure range of 200 to 250 Barg (20-25MPa) , allowing for precise configuration based on the regulations of the target market or specific customer operational needs. Whether serving as a gas source for CNG fueling stations or for direct supply to industrial users, Huayan's modular design demonstrates strong adaptability.

Crucially, these specifications are not fixed. From the number of cylinders (ranging from 6 to 16), individual cylinder volume, and working pressure, to the overall dimensions (20ft or 40ft) and the configuration of valves and instrumentation—everything can be deeply customized to match your actual operational requirements. This ensures every piece of equipment delivered achieves the optimal balance between transport efficiency and safety performance.
