Large LPG Mounded Storage Vessel for Commercial Gas Plants
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: Are your LPG storage tanks standard products or fully customizable?
A: Main specifications have mature standard designs. We support customized design on capacity, wall thickness, nozzle position, saddle structure, safety valve assembly, painting and auxiliary instrument set according to project site conditions and transportation restrictions.
Q2: What is the maximum filling ratio for industrial LPG storage tanks you manufacture?
A: The default filling ratio is designed at 80% in accordance with international LPG safety codes. We can adjust design parameters strictly following local gas authority regulations of your target country.
Q3:What safety accessories are included in the standard scope of supply?
A: Standard package contains pressure relief valve, liquid level gauge, pressure transmitter, manhole, inlet & outlet nozzles, drain connections and safety blocking fittings. We can upgrade full set of vapor recovery system and leak detection devices on demand.
Q4: What is the difference between above-ground and underground LPG storage tanks in fabrication?
A: Above-ground tanks adopt anti-ultraviolet external coating. Underground tanks require extra heavy-duty anti-corrosion coating plus cathodic protection structure. Foundation design and inspection standards are different for two installation modes.
Q5: Can you supply LPG storage tanks matched with filling station skid-mounted systems?
A:Yes. We have rich experience supporting complete LPG filling station projects. We can coordinate tank dimensions, interface standards and technical parameters to match pumps, vaporizers and control skids from your designated suppliers.
Q6: What is your normal production lead time for LPG storage tanks?
A: Standard specification tanks require 25–35 working days. Customized tanks with special certification or complex nozzle layout take 35–50 working days. We will confirm exact schedule after drawing confirmation.
