Horizontal LPG Mounded Bullet for City Gas Distribution
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: What delivery terms can you offer for LPG storage tank export?
A: We support EXW, FOB major Chinese ports, CFR and CIF. For oversized tanks, we will pre-check road transport limits and arrange bulk vessel shipping solutions. We provide proper export seaworthy packaging.
Q2: How do you pack large LPG storage tanks for ocean shipment to avoid coating damage?
A: lpg gas Tanks are fixed with reinforced transport saddles; exposed flanges and nozzles are sealed with waterproof protective covers. We apply anti-collision protection on key areas, and provide lashing scheme for vessel loading.
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: Can you send technical engineers to guide on-site installation and commissioning?
A: We can arrange professional technical supervisors for overseas site service. Service fees, travel expenses and schedule will be listed separately in the quotation according to project location.
Q5: What is the designed service life of your carbon steel LPG storage tanks?
A:Under normal operating conditions and regular maintenance, the designed service life reaches 15 years. Actual service life depends on medium corrosiveness, ambient environment and daily inspection schedule.
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.
