Many buyers look at CNG cylinder bundle products with a specific site already locked in — a dockyard, the edge of a mining area, or an irregularly shaped plot in an old city district. In such cases, standard-sized ground-mounted fixed storage units are difficult to apply directly. So the natural question arises: Can this bundle really be adapted to my site? Can it be containerized for easy lifting? Can the connection standards match my local piping? This article starts directly from the product parameters of Huayan's CNG cylinder bundle and breaks down the customization capabilities item by item — no beating around the bush.
Three deployment forms, not three products
Huayan's CNG cylinder bundle is not limited to a single fixed form.
Deployment Form | Frame / Enclosure | Corresponding Water Volume | Suitable Scenarios |
Open Frame Skid | Steel frame integrated, forklift or crane/rigging direct placement | Customizable as needed (8-12 cylinder combination) | Standard gas stations, industrial parks, fixed storage points |
20FT Containerized | Standard 20-foot shipping container enclosure | Approx. 1066 L water volume | Dockyards, temporary gas filling points, scenarios requiring container ship transport |
40FT Containerized | Standard 40-foot shipping container enclosure | Approx. 2450 L water volume | High-flow gas supply, long-distance transport and distribution, remote mining areas |
Which one to choose depends on whether the site has lifting capabilities, whether container-standard ship transport is required, and whether the site can accommodate the footprint of a fixed frame.
Four items that can be customized — not "theoretically possible"
Customizable Item | Optional Range | Note |
Cylinder specification & quantity | Φ356 mm / Φ559 mm large-diameter seamless steel cylinders, 8–12 cylinders per group, flexibly adjustable | Single cylinder water volume 2000–3000 L (large diameter) or 150–200 L (small-cylinder flexible model) |
Working pressure | 20 MPa (200 bar) / 25 MPa (250 bar) | Two options, match downstream dispenser rated pressure |
Connection type | Standard high-pressure flange / quick coupling | Inform local piping standard when ordering; corresponding interface pre-assembled at factory, ready for direct connection upon arrival |
Certification documents | ISO9001 / ISO14001 / CE / ASME / ADR | Provide corresponding certification documents as per importing country's special equipment regulatory requirements |
Two points worth mentioning separately:
First, the number of cylinders is not fixed. It is not a fixed package, but a combination arranged according to demand.
Second, the interface is not modified on-site after arrival. The flange specification and quick coupling model are determined at the time of ordering, and the entire piping system is pre-assembled and leak tested according to this interface before leaving the factory. This is also critical for the import customs clearance process — the equipment arriving at the port is a complete, factory pressure-verified gas storage system, not a pile of loose parts that need on-site assembly.
Note: these five items are key information that can directly determine the efficiency of solution implementation when making an inquiry:
1. Available area and ground load-bearing conditions of the site — determine frame size and leg distribution.
2. Whether frequent relocation is needed — determines whether to choose open frame skid or containerized enclosure.
3. Gas source — from tube trailer unloading, city pipeline network, or compressor outlet? Inlet pressure range varies.
4. Interface standard of downstream dispenser — determines factory flange / quick coupling model.
5. Requirements of the importing country's special equipment regulatory authority — determines the list of accompanying certification documents.
If the above five items are not yet determined, that is also fine. Huayan can issue technical suggestions based on common regional solutions, and the buyer can then confirm with local engineers.
Parameter | Specification |
Number of cylinders | 8–12 cylinders/group, customizable |
Single cylinder water volume | 2000–3000 L (large diameter) / 150–200 L (small cylinder) |
Cylinder specification | Φ356 mm / Φ559 mm |
Working pressure | 20 MPa (200 bar) / 25 MPa (250 bar) |
Capacity example | 2500 L @ 20 MPa ≈ 5000 Nm³; 6000 L @ 25 MPa ≈ 15,000 Nm³ |
Cylinder material | 30CrMoL high-pressure cylinder special steel |
Connection type | High-pressure flange / quick coupling |
Frame form | Open frame skid / 20FT container / 40FT container |
20FT container water volume | Approx. 1066 L |
40FT container water volume | Approx. 2450 L |
Certifications | ISO9001 / ISO14001 / CE / ASME / ADR |
Applicable scenarios | Gas station level buffer storage, city gas distribution, fleet centralized refueling, industrial park gas supply, remote construction sites, temporary gas filling points, CNG distribution |
The question of whether a cylinder bundle has "customization capability" can actually be broken down into three independent judgments: whether the cylinder combination can be adjusted, whether the interface can be pre-configured, and whether the frame can fit into your site. Huayan's product parameters have already answered "yes". All that remains is for the buyer to fill in these fields clearly and send them over.
