[Quick Overview of Core Product Specifications]

[Core Competitive Advantages of the Product]
1. [Ultra-Low Evaporation Loss] Preserve every drop of fuel gas with BOG self‑circulation and reuse.

Key selling point: It employs imported composite molecular sieves and multi-layer aluminum‑coated films, with a vacuum level in the sandwich structure maintained at ≤ 0.01 Pa over the long term.
Effect: In conjunction with the LNG storage tank’s auto‑pressurization system, the BOG generated under normal operating conditions is used to maintain tanker unloading and tank pressurization, eliminating the need for external energy sources and enabling a zero‑emission BOG micro‑circulation.
2. [Integrated Skid-Mounted Design] Covers an area of less than 25 m², with a construction period of only 3 days.

Key Highlights: Retrofit of LNG cylinder‑bank stations and foundations for small‑capacity LNG storage tanks.
Key selling point: The unit is delivered as a skid-mounted package, integrating a storage tank, vaporizer, and pressure-regulating metering system. Pre‑fabrication of piping at the factory reaches ≥85%.
Effect: No need to construct extensive pile foundations or foundation rafts—only a 10-cm-thick reinforced concrete floor is required. Rapid commissioning and flexible relocation via crane are possible at any time.
3. [304 Stainless Steel Inner Liner with Fully Automatic TIG Welding] Eliminates Leaks

Key Highlights: LNG tank cleaning and purging, and inner-tank materials.
Key selling points: Adheres strictly to the NB/T 47014 welding procedure qualification standard; the inner cylinder butt welds undergo 100% RT (X-ray) nondestructive testing; and the interlayer is leak-tested using helium mass spectrometry.
Performance: Zero risk of leakage over the product’s entire service life; it remains crack‑free even under the extreme thermal shock of LNG pre‑cooling, and is backed by a 20‑year vacuum‑life warranty.
4. [Intelligent Localized Operations and Maintenance] User-Friendly Operation and Intelligent Level Gauges

Key Highlights: LNG tank level gauges, tank differential pressure level gauges, and intelligent LNG management.
Key selling points: Standard configuration includes a flanged differential pressure level transmitter and a top-mounted direct‑read level gauge (redundant design); an optional 4G IoT remote transmission module is available.
Features: Users can monitor liquid level, pressure, and volume directly from their mobile phones. When the liquid level drops below 20% or the pressure approaches the safety valve’s set‑off pressure, the system automatically triggers an alarm. It also supports connectivity with government‑approved gas safety monitoring platforms.
[Applicable Scenarios]
Small-scale LNG vaporization stations/industrial on-site supply: 1–2 horizontal 60-cubic-meter storage tanks, paired with a 300–500-cubic-meter vaporizer, capable of meeting the daily gas consumption of 10,000–20,000 cubic meters for glass, ceramic, and hardware manufacturing plants.
LNG vehicle refueling stations (L-CNG): serve as an alternative to underground storage tanks at refueling stations, or as secondary storage tanks.
Coal-to-gas conversion and peak‑shaving reserve: In areas where township gas pipelines have not yet been extended, upgrade and replace existing systems by establishing small LNG cylinder‑group vaporization stations (each tank offers greater storage capacity than a Dewar flask and ensures more stable gas delivery).
Large-scale livestock farms / Independent heating: In conjunction with gas-fired boilers, provide district‑scale clean heating to replace heavy oil or coal.
[Frequently Asked Questions]
Q1: How much does a 60-cubic-meter LNG storage tank cost per unit? How long will it take to recoup the investment?

A: LNG storage tank prices are influenced by nickel prices and steel‑related policies, but a 60‑cubic‑meter tank remains relatively cost‑competitive. Based on current industrial gas price differentials, many users switch from diesel or heavy fuel oil to LNG for on‑site supply; under full‑load operating conditions, the equipment investment can be recouped in 6 to 10 months.

Q2: Is a 60-cubic-meter tank considered special equipment? Are the required procedures complicated?

A: Yes, it is classified as a Class III pressure vessel. Our manufacturer will provide a certificate of conformity with the shipment. Users are required to apply for a Special Equipment Use Registration Certificate from the Special Equipment Division of the local Market Supervision Administration, and we will supply comprehensive supporting documentation to facilitate the process. This eliminates the need for the cumbersome fire safety and safety‑assessment approvals typically required for large full‑containment tanks.

Q3: How much land does the storage tank occupy? How far from buildings is it safe to place it?

A: Each individual storage tank, including its foundation, occupies approximately 4 m × 5 m. Fire‑resistance clearances must strictly comply with the “Code for Design of Town Gas” GB 50028; typically, a minimum distance of 15–20 meters from residential buildings is required. If a two-hour fire‑resistant wall is constructed, this clearance may be reduced. We can provide a safety‑clearance diagram.

Q4: After 3–5 years of operation, if the vacuum level drops and the tank shell starts to sweat and frost over, can it be repaired?

A: Yes, that’s possible. The specialized procedure is called “Vacuum Regeneration of the LNG Tank Jacket.” We restore its adiabatic vacuum level by performing thermal purging, replacing the deactivated molecular sieve, and continuously evacuating with a high‑vacuum unit, thereby eliminating shell‑to‑shell thermal bridging.
