Industrial LPG Mounded Bullet Tank for Bulk Storage Terminals
Product Overview
Our underground LPG storage tanks are engineered for safe, efficient, and space-saving liquefied petroleum gas storage. Designed and manufactured to international standards (ASME Section VIII,GB 150), these horizontal buried tanks deliver superior safety performance, reduced land footprint, and lower operational costs compared to above-ground alternatives.
With capacities ranging from 5m³ to 200m³, our underground LPG tanks serve LPG filling stations, industrial facilities, commercial complexes, residential communities, and resort projects across the Middle East, Southeast Asia, Africa, South America, and Central Asia.
Why Choose Underground LPG Tanks?
Underground LPG storage represents a strategic upgrade from conventional above-ground tanks, addressing three critical buyer priorities: safety compliance, land cost optimization, and long-term operational economy.
|
Advantage Category |
Underground lpgTank |
Above-Ground lpgTank |
|---|---|---|
|
Safety Performance |
Earth insulation provides natural fire protection; reduced explosion risk; gas disperses quickly if leaked |
Exposed to fire risk; requires larger safety distances; higher visible hazard profile |
|
Land Usage |
Minimal surface footprint; tank area can be landscaped or used for parking |
Requires full surface area + safety buffer zones |
|
Thermal Stability |
Constant underground temperature reduces evaporation loss by 30-50% |
Exposed to temperature extremes; higher boil-off rate |
|
Aesthetic Impact |
Virtually invisible above ground; ideal for resorts, urban areas |
Visible industrial structure; zoning restrictions |
|
Service Life |
20+ years with proper cathodic protection and coating |
15-20 years; weather exposure accelerates corrosion |
|
Theft/Vandalism |
Buried installation prevents unauthorized access |
Exposed valves and fittings vulnerable to tampering |

FAQ
Q1: How do you detect leaks in an underground tank?
A: We recommend installing gas detection sensors in valve pits and around the tank perimeter. We also offer optional smart monitoring systems with remote level, pressure, and leak detection capabilities. Regular pressure testing and cathodic protection monitoring also help identify potential issues early.
Q2: What is the typical lead time?
A: Standard models: 20-30 days after deposit. Custom designs: 30-45 days. Large orders (5+ units): negotiable. We maintain certain popular sizes in stock for urgent projects.
Q3: What are the payment terms?
A: Standard terms: 30% T/T deposit, 70% balance before shipment. L/C at sight is also acceptable for larger orders. We can discuss flexible payment terms for established customers.
Q4: How is the tank shipped?
A: Small tanks (up to 20m³) can be shipped in 40HQ containers. Larger tanks are shipped via bulk carrier or RORO vessel. We handle all export packaging, documentation, and logistics arrangements.
Q5: Can your tanks be imported to [specific country]?
A:We have exported to over 70 countries worldwide. We are familiar with import requirements for most major markets and can provide the necessary documentation (CO, CI, BL, certification, etc.).
Q6: Do you offer third-party inspection services?
A: Yes, we accommodate third-party inspection by companies like SGS, BV, TUV, and others. Inspection can be arranged at different stages: material inspection, in-process inspection, final inspection, and loading supervision.
