For any inquiries regarding lpg storage tanks, please reach out to us. Our knowledgeable sales team is here to assist you in finding the most suitable options for your requirements.

LPG storage tanks serve as specialized containers designed for the safe storage of liquefied petroleum gas (LPG), catering to various industrial and commercial applications. What constitutes an LPG storage tank, what structural characteristics does it possess, and what are its practical applications? Below is a comprehensive discussion on these essential points regarding LPG storage tanks!

1. Overview of LPG Tanks

What constitutes LPG storage tanks? How are these tanks constructed, and what are their prevailing market prices? Let's delve deeper.

1.1 Understanding LPG Tanks

An LPG tank—often referred to as an LPG container, industrial gas tank, or liquefied gas tank—serves the crucial function of storing liquefied petroleum gas. This gas is commonly utilized as a fuel source across industrial, agricultural, and commercial sectors. LPG is generally stored in a liquid state by applying high pressure, allowing for easier transport and storage.

LPG storage tanks must adhere to stringent quality standards due to the gas's rapid expansion and flammability. They are designed in two primary configurations: upright or horizontal, depending on space considerations and specific usage requirements.

1.2 LPG Storage Tank Structures

Built from resilient and corrosion-resistant materials such as SUS304, SUS201, SUS316, CT3, SS400, and black or white steel, industrial gas tanks typically comprise four key components:

• Tank Body: Usually cylindrical or rectangular, this component includes three layers: an outer metal shell, a middle vacuum insulation layer, and an inner shell that contains the gas. This structure ensures thermal insulation to mitigate the expansion of liquid gas due to rising temperatures.
• Tank Lid: This part generally adopts a flat or conical shape to enhance the tank's pressure resistance.
• Tank Bottom: Similar in shape and construction to the tank lid.
• Tank Legs: These supports can be round or L-shaped, designed to sustain the entire LPG storage tank.

Furthermore, LPG storage tanks include safety shut-off valves and other specialized components such as:

• Safety valve
• Temperature sensor
• Thermometer
• Weight sensor
• Flange
• Sight glass
• Pressure sensor
• Thermometer sensor
• Heating system
• Motor-controlled stirrer via a frequency converter.

1.3 LPG Storage Tank Safety Standards

When it comes to design, installation, and operation, LPG storage tanks necessitate strict adherence to safety protocols to mitigate risks of fire and explosions. Article 3 of QCVN 10//BCT, issued by the Ministry of Industry and Trade, outlines explicit safety regulations for LPG supply stations. This necessitates compliance with established technical standards during construction, alongside rigorous monitoring and inspections every three years to ensure operational safety.

1.4 LPG Storage Tank Pricing

The pricing of an LPG storage tank is influenced by four main factors:

• Supplier: Pricing may differ among manufacturers, even for tanks of similar capacities and materials.

In addition, the cost of transportation and installation contributes to the overall pricing of LPG storage tanks. Typically, tanks with capacities between 5 and 10 tons may range from 400 to 500 million VND. For precise quotes, you may contact Gas South for specialized advice.

2. Applications of LPG Storage Tanks

LPG storage tanks are vital in securely storing and distributing liquefied petroleum gas across various sectors, including agriculture, residential, commercial, and industrial domains. Their benefits include:

• A stable, safe, and economical fuel supply to prevent disruptions in production and business activities.
• Versatile storage solutions with capacities from 5 to 50 tons, tailored to customer needs.
• Options for above-ground or underground tanks that optimize storage space.
• Safety features including vaporization systems, alarms, pressure regulation, explosion prevention, and easy maintenance.

LPG storage tanks find extensive use in numerous industries, including brick and tile manufacturing, ceramics, and food processing. Commercially, they provide flexible fuel solutions for hotels, restaurants, and supermarkets, while in agriculture, they power heating systems in colder regions. Smaller LPG tanks are also commonly utilized in large research laboratories.
