CNG Type 1 Cylinder Purchasing Guide for Vehicles

When selecting a CNG Type 1 cylinder, the core points to focus on are safety first and compliance above all else!

The CNG Type 1 cylinder refers to a gas cylinder made entirely of metal (typically high-strength steel) for vehicle use. This is the most common and historically oldest type of CNG cylinder.

Advantages:

Mature technology, sturdy structure, good high-temperature performance, strong resistance to external impacts.

Relatively low price (compared to other types).

High recycling value (as scrap steel).

Disadvantages:

Heaviest weight (affecting vehicle load and fuel/energy consumption).

More sensitive to corrosion (especially internal stress corrosion and external damage after collisions).

Relatively shorter service life (typically 15 years with mandatory scrapping).

Shorter inspection cycle (typically every 3 years).

Applicable Scenarios:

Suitable for vehicles where weight sensitivity is not a major concern, budget is limited, and usage intensity is moderate, such as taxis, private cars, and some city logistics vehicles.

CNG Type 1 Cylinder Purchasing Suggestions

Volume Matching Power Demand: The type I CNG cylinders volume directly determines the mileage per refueling. Bigger is not always better, as it requires balancing vehicle space layout, load limits, and range requirements. Calculation reference: Generally speaking, 1 liter of water volume can store approximately 0.2-0.25 cubic meters of natural gas. By combining the vehicle’s fuel consumption per 100 kilometers, you can estimate the required volume. For example, if the fuel consumption is 25 cubic meters per 100 kilometers, and the desired range is 400 kilometers, a cylinder with a 100-liter water volume would be required (specific selection should be consulted with a professional). It is recommended to choose a cylinder size that matches the vehicle’s chassis space design to ensure safe and stable installation.

Certification Labels for Safety and Compliance:

Core Certification:
In the Chinese market, it is essential to look for the “Special Equipment Manufacturing License” issued by the State Administration for Market Regulation, particularly the A1 level (high-pressure vessel) certification. This is the cornerstone of legal market entry and safe use.

International Standards:
If the vehicle is for export or requires high standards, check whether the product complies with ISO 11439 (international standard for CNG cylinders for vehicles), EU ECE R110, and other authoritative regulations. These standards impose strict requirements on materials, design, manufacturing, and testing.

Quality Endorsement:
ISO 9001 Quality Management System certification and ISO/TS 16949 (now IATF 16949) automotive industry quality management system certification are signs of a manufacturer’s stable and reliable production capability.

China cng type 1 gas cylinder Manufacturers HSDP, which has been deepening its expertise in gas storage for over a decade, not only holds a full range of domestic special equipment manufacturing licenses (A1/B1/B2/B3/C2/C3) but also ensures that its CNG cylinder products strictly comply with international standards such as ISO 11439, providing compliance guarantees to global users.

Choose a Reliable and Scalable CNG Cylinder Manufacturer: 

Select manufacturers with long-term research, development, manufacturing, and extensive application experience in the vehicle gas cylinder field. Mature experience means a deeper understanding of material properties, process control, and failure modes, leading to higher product reliability. Large-scale production bases usually mean more advanced manufacturing equipment, stricter quality control processes, and a more stable supply chain. For example, HSDP, one of Asia’s leading vehicle gas cylinder production bases, transforms its scale advantages into consistent product quality and reliability.

HSDP Service Assurance

• Installation and Maintenance:Provides professional installation services and regular cylinder inspection and maintenance support. As CNG cylinders are pressure vessels, regular inspections (typically every 2-3 years) are a legal requirement.
• Warranty Commitment:Clear warranty terms are provided.
• Spare Parts Supply:Ensures smooth channels for the supply of essential or regularly replaced parts such as valves and pipeline connectors.

Safety is the Bottom Line, Quality is the Dignity

CNG cylinders are mobile pressure vessels, and their safety is an absolute bottom line. Choosing a CNG Type 1 cylinder for your vehicle is a comprehensive investment in safety, economy, and efficiency. By mastering the four key points—volume matching, certification recognition, manufacturer evaluation, and service assurance—you can find the strong, reliable, and durable “heart of energy” for your vehicle, ensuring every green journey is safe and worry-free.
