LPG (liquefied petroleum gas
) is a fuel used for cooking, heating, hot water, diesel fuel substitutes, heating engines, barbecues, and lighthouses. It is also used as a refrigerant and in the production of plastic and as feedstock for refineries. An LPG tank is a large container with an outlet to store liquefied petroleum gas in its liquid state under a certain pressure. LPG tanks can be buried underground or placed above ground in open areas.According to the historical evolution of LPG tank construction and utilization, there are two types of LPG tanks:
Vertical Cylinder Tanks
Vertical Cylindrical tanks are uniformly shaped tanks that are oriented upright. Vertical LPG tank sizes have a cylindrical shape with no changing curves or edges. The average height of vertical cylinder tanks is equal to or greater than their diameter. Vertical Cylinder Tanks are typically made from steel or iron that is coated with paint or plated with chromium on the exterior surface. Tanks with a large capacity are installed underground to prevent outdoor exposure in regions with temperature changes between hot and cold. The outdoor cylinders are chained or somehow secured to the grill to prevent tipping when moving.
Horizontal Cylinder Tanks
Horizontal LPG tanks are simple pressure vessels with end caps that are permanently welded on. They are manufactured in the same manner as vertical cylinders, but the tanks have to be square and sit on a platform for this method of inspection to be applied. The frequently used materials are aluminum and carbon steel. Above-ground horizontal tanks are used in lawn care and the agricultural sector. Because they are stowed horizontally, they are more stable and less likely to tip over when being transported.
The shelf life of an LPG tank is extended by frequent inspections and proper maintenance. There is no commonly determined expiry date for LPG tanks. Proper maintenance and inspection of the cylinder will prolong its life.
LPG tanks are categorized into two types, each serving a different purpose depending on their location:
Above-ground LPG tanks
Above-ground LPG tanks are manufactured of durable metal or plastic and are secured by bolts that are being used for their holding action. The cradles and skids frequently used with this kind of tank serve as temporary stands for moving and gracing the tank. To cover and shield hose connections and valves on top of the tank from possible external damage, an over-the-valve tank is sometimes used in conjunction with a safety cover. Above-ground tanks are mobile, and quick refueling is possible anywhere there is an above-ground tank.
Underground LPG tanks
When the cylinder is buried underground, it is referred to as an underground or under-tank. Underground tanks are occasionally referred to as stubby tanks because they are shorter and look like cylinders. These are constructed from materials that are corrosion-resistant. They might have a bigger capacity than above-ground tanks to fulfill the requirements of rural residences and sizable agricultural applications. They give rural houses a secure supply of fuel because there isn't any visible storage on the property.
Nominal Capacity
For each tank, the nominal capacity is an important but sometimes ignored number. The nominal capacity is the amount of cargo that can be transported, usually measured in gallons or litres. However, due to tank design and other factors, the actual usable volume may be less than the nominal capacity.
Tank Dimensions
Tank sizes refer to the LPG cylindrical tanks most commonly used for transportation. These tanks are typically cylindrical with flat ends. The length and diameter of the cylinder determine the size of the tank. Common sizes include 20 feet, 30 feet, 40 feet, and other lengths. The diameter is generally around 2 to 3 feet.
Working Pressure
The working pressure of an LPG tank indicates its ability to withstand internal pressure. This factor is critical to ensuring the safety of transporting and storing liquefied petroleum gas. LPG is a highly volatile and flammable fuel derived from natural gas and petroleum refining processes. Working pressure is a crucial guarding point to prevent the tank from being damaged by excess pressure during gas transportation and storage.
Periodic inspections
LPG tank users should regularly check the tank for damage, corrosion, leakage, etc. If any problem is found, they should repair it in time. Do not arbitrarily modify the facilities and equipment of the gas tank.
Clean the gas tank
Cleaning the outside of the tank properly can avoid the corrosion of dirt and other foreign objects, but cleaning the inside of the tank requires professional personnel and equipment.
Pay attention to ventilation
Keep the gas tank well aired to avoid the buildup of flammable gas and reduce the risk of fire and explosion. Users should also pay attention to the distance between the tank and other facilities, equipment, and structures, and strictly comply with relevant regulations and standards to avoid potential safety risks.
Indoor heating and cooking
Smaller LPG tanks are typically used in households for indoor heating and cooking. Whether in a rural area where natural gas isn't available or in centralized urban places where people prefer using propane for its efficiency, these compact sized tanks provide an abundant and easily controllable source of heat for warmth and food preparation.
Outdoor grills and camping stoves
The portable LPG tanks with a capacity of 5kg to 15kg are ideal for outdoor barbeque and camping fueling requirements. Such tanks can be easily transported, enabling people to take their cooking adventures anywhere, from backyard patios to deep in the woods on camping trips.
Vehicles
Liquefied petroleum gas tanks are also available in the double cylinder or collared tanks fitted to vehicles. They come in different sizes and are usually placed at the back of the trunk to maximize engine performance while minimizing emissions on the road by allowing the vehicle's engine to run on gas sourced from these collared cylinders.
Industrial manufacturing and agriculture
Large, fixed, or semi-fixed large bulk LPG tanks are often used in manufacturing sectors, including textile and other relevant industrial factories. Similarly, the agriculture industry utilizes them for farming-related tasks because of their capacity to hold great amounts of fuel under pressure, which is then released in a controlled manner as required by pyrolysis, propelling machinery, or heating greenhouses and poultry houses. This makes liquefied petroleum gas an instrumental species in both industrial production lines and agricultural cultivation systems.
When purchasing an LPG tank, the sizes are critical since they will help match the availability of the tanks and the demand for LPG.
Needs Assessment
Before buyers get the tanks, they should start by assessing their needs. They should consider factors, such as the energy demand of the appliances they intend to use the gas for, the consumption rate and frequency of refilling.
Property Visit
For buyers intending to purchase permanent or large LPG tank sizes, they should visit the property where the tank will be installed. They should take measurements and consider any zoning regulations that might limit the size of the tank. Also, they should consider the distance from the supply truck to the tank site. It should be an easy distance to supply the gas.
Supply Options
Determine the supply options available. Some suppliers offer automatic refilling services while others require manual ordering. Customers who prefer automatic refilling should choose a tank size that accommodates their demand between refills.
Budget Constraints
When choosing the sizes of the LPG tanks, buyers should consider budget constraints. Larger tanks tend to be more expensive and they might incur higher installation and maintenance costs. Evaluate the budget and choose a tank that meets the financial capability.
Long-Term Plans
If buyers have long-term plans of staying in their current location, they can invest in a larger tank to accommodate future energy needs. On the other hand, if they are unsure of the long-term plans, they should settle for a portable tank whose size is uncertain.
Safety and Regulations
Ensure the chosen tank size complies with safety standards and local regulations. When unsure, consult with local authorities or experts to get more clarification on the safe tank size.
