What is a mobile gas tank?
Gas tank called storage tank for liquefied gas, which is a mixture of butane and propane. Such devices are used to organize autonomous gas supply houses and plots. If you install a gas tank on the frame with wheels, you get a convenient mobile version, the possibilities of which are much wider.
The capacity of the mobile storage of LPG is usually about 600 liters. This is enough to replace 12 ordinary gas cylinders at once. Although if you wish, you can find a device with a capacity of 1000 liters or 1200 liters, and even very small ones - by 480 liters. The frame for the transportation of the gas tank is a modified trailer for these needs.
The tank is made of durable galvanized steel securely fastened to the frame with a wheeled chassis, one- or two-axle. This design can be attached as a trailer to the car and transported to the right place. Of course, it is impossible to connect a gas-holder located on an unstable trailer with gas appliances.
Mobile gas-holders are convenient and compact devices that are easy to install, safe, reliable and have a fairly wide scope of application.
First you need to fix the position of the structure. For this purpose, special stops - outriggers, which are usually three or four. After the position of the device is securely fixed, you can use it in accordance with the purpose.
The contents of the gas tank is a mixture of liquefied gases, hermetically sealed in the vessel. Natural or artificial gas mixture is contained in a closed tank under a pressure of 1.6 MPa.
Mobile gasholder must always be covered with an awning made of polymeric materials to reliably protect the device from the sun and weather
Among the advantages of using a gas tank can be noted:
- mobilitywhich opens up the possibility of using a gas-holder not only on one, but also on several objects for solving various tasks;
- decent capacitywhich may vary between 500-1200 liters;
- easy installationWith some experience you can connect to the gas pipeline system at home yourself, following the manufacturer's instructions;
- the ability to choose the option of refueling: at the gas station or using a special car;
- convenient control system, information on the status of the device is displayed on the panel with indicators, etc.
The disadvantages of the device include the rather high cost of a gas storage tank.
Still, the use of a mobile gas tank, according to customers, is much more convenient than using a set of standard cylinders with a similar total capacity. As for safety, when properly used, problems in this regard almost never arise.
Small-sized mobile gas tanks are compact enough, so they can be installed even in small summer cottages
An important point in the configuration of the gas tank on wheels is the presence or absence of forced heating of the tank. The fact is that even in the not-too-cold frost the evaporation process even of the “winter” mixture of LPG can be significantly slowed down.
In the southern regions, where the winters are warm, this problem is not relevant, but for residents of the northern regions it is recommended to choose a device that is equipped with a forced heating function.
In order to ensure the normal evaporation temperature of liquefied gas in winter, the mobile heating system the gas-holder, which does not have additional functions, is connected to the heating circuit of the object, to which gas. Built-in heating is carried out using an autonomous boiler plant.
This device allows you to use LPG in the most rational way, for its work does not need electrical energy. But there are modern models in which heating is carried out with the help of electricity. For this purpose, a special carbon fiber film, compact and safe.
The control unit automatically switches off the mini-boiler room to avoid a dangerous level of heating. In addition, there is a safety valve that triggers if the pressure inside the vessel reaches a critical level.
Excessive pressure (more than 500 kPa) can lead to deformation of the container and even to the violation of its tightness.
Mobile gas tanks are supplied equipped with a set of devices that are necessary for connecting and monitoring the operation of the system, which facilitates installation
Containers with flammable contents should be protected from the effects of natural factors. For this purpose, the gas tank is covered from above with an awning from polyvinyl chloride. This material is well tolerated and heat, and cold, and rain, and other weather changes.
To connect the tank with LPG to the gas equipment, corrugated nozzles are used, which are equipped with high-quality detachable connections.
These assemblies are designed in such a way that when they are opened, any gas leakage is excluded, thereby avoiding unnecessary losses of coolant during connecting the gas tank to the facility, disconnecting, refueling, etc. Shut-off and control valves almost completely exclude the likelihood an accident.
Mobile gas tank can be mounted on a separate standard trailer or mounted on a similar device, you can choose the most suitable option
Mobile gas tanks are usually completed with gas hoses that are enclosed in a layer of insulating material. This additionally protects the liquefied gas from temperature fluctuations during the filling of the tank and during the movement of gas to the object.
Each gasholder is equipped with a gearbox. This device is designed to maintain a stable level of gas pressure at the outlet, which contributes to the integrity of the connected gas equipment.
Mobile gas tank options are installed on a two- or four-wheeled chassis, but the device should be fixed with outriggers before connecting and starting work
In order to save some owners of private houses are thinking about buying a gas-holder, which was already in use. This is a possible option, but remember that each device has a maximum lifetime.
In addition, it is not always possible to obtain information on how the previous owner handled the gas tank. In any case, to make such a purchase is possible only after inspection of the device by an experienced specialist.
How does LPG evaporate
Why is a mixture of liquefied gases used for such a device? The fact is that propane and butane react differently to an increase in the ambient temperature.
Propane evaporates better, therefore, a mixture of LPG is made in two versions - summer and winter. In the first case, the ratio of propane and butane in the composition is about the same, but for use in winter, the composition in which the propane content is 90% is more suitable.
The table allows you to compare the efficiency of using different types of fuel for heating residential premises and to draw conclusions about the benefits of using LPG for these purposes (+)
What will happen if during a cold weather the gas-holder will work without heating? Butane, which is contained in a mixture of liquefied gas, stops evaporating. As a result, only propane, the second element of the mixture, enters the system.
After all the propane has been used, a portion of the volume (30-50%) in the tank will remain filled with unused butane. It would be reasonable to pump this gas out of the reservoir in order to free up useful space, but this is troublesome, they usually do not do this, but simply refuel the balloon with a new portion of LPG.
If you continue to use the tank in the wrong mode, gradually its volume will be completely occupied by butane. The use of a gas tank will be impossible until the pumping of unwanted gas is complete, which will lead to significant additional costs.
Do not use a certain type of LPG mixture in the wrong period for it. The composition will evaporate either too slowly or too quickly. This will adversely affect the performance of the equipment and its condition. A fairly wide temperature range is considered acceptable for storing LPG: from -40 ° C to + 45 ° C.
Reliable protection of the mobile gasholder from the effects of natural factors is imperative. If possible, an additional carport should be made for the device.
In the process of filling the gas tank can be faced with unscrupulous gas supplier. For starters, this is the underfilling of the tank to full capacity. For successful deception of a buyer, pseudo-craftsmen simply turn up the counter so that it shows the wrong numbers. The second common variant of deception is filling the summer mixture instead of the winter one.
The fact is that propane is more expensive than butane. The summer mix contains 50% butane instead of 15%, which is necessary for the winter mix. As a result, the tanker sells a cheap summer train for the price of a more expensive winter one.
Since the standalone version of the gas tank has small volumes compared to stationary models, it is more difficult to cheat with volumes, because the difference will be noticeable.
It is easier to deceive the owner of a stationary gasholder and steal 30-40 liters from a 4,000-liter tank, but if the meter is boosted, then deception is quite possible on small volumes. Therefore, it does not hurt to check the level gauge after refueling, if it is in the gas-holder.
Where use mobile gas storage
Mobile gas tanks are used for various purposes:
- on construction sites;
- for garden houses;
- at the cottages;
- for trailers and cabins;
- as a means of emergency gas supply, etc.
For example, on an area of five to six hundred square meters, the technical conditions do not allow setting stationary model, it remains to either carry cylinders, or use the mobile version, which much more convenient. It and need to fill less often and easier to use.
If extensive earthworks are needed to install a stationary underground gasholder, then it will take a maximum of an hour to install a new mobile model.
From the mobile gas tank can be powered boiler, they are used to perform gas welding, to conduct roofing works, such as drying of surfaces, installation of built-up materials: roofing material, its bituminous and polymeric analogs, etc.
In combination with a good gas convector, designed for economical fuel consumption, mobile gasholder will be an excellent choice for heating garages, outbuildings, cabins and other similar objects.
Features of installation and operation
Making the installation of a mobile gasholder on a trailer with electric heating is much easier than installation of stationary model. Special permissions from the gas distribution company will not be needed in this case. But the trailer chassis, of course, must be properly registered with the traffic police.
You do not need to get a special permit to install a mobile gasholder, but it should be registered with the traffic police like any caravan
At the same time, it is necessary to follow the same registration procedure that is used when taking into account ordinary car trailers of mass production.
When purchasing a gas tank, you should make sure that all necessary documentation is attached to the tank, namely:
- quality certificate;
- technical passport of the tank;
- vehicle passport;
- instruction manual of the device.
Permission to install a mobile gasholder is not required, but the unit must necessarily have all the necessary certificates. If such documents are not available, the owner of the gas-holder can be denied to fill the tank with liquefied gas.
But the simplified registration procedure should not be a reason for careless handling of the device, which is a high-risk object.
Even before filling and connecting the gas-holder, you should carefully study the instructions for its installation and operation, and then strictly follow all the manufacturer's recommendations. It is best to invite an experienced specialist to ensure that the gas tank is properly and safely connected to the heating circuit or other equipment consuming gas.
Standard models of mobile gas-holders are equipped with the necessary control and regulation equipment, which ensures safe operation of the device, if the necessary conditions are met
This is especially true if a heated model is chosen, since a professional master will also set up a mini boiler room. To connect the gas tank yourself, first you need to carefully study the instructions and follow the recommendations contained therein.
Quick connectors allow you to connect the device in just a few minutes.
At the same time, gas leakage from the system and the ingress of outside air into it are excluded. There are no strict requirements for the placement of such a gasholder on the site.
Of course, the distance from the gasification object is limited by the length of the feed pipe. To ensure that the device lasts as long as possible without breakdowns and accidents, it should be installed in such a way as to prevent prolonged exposure to direct sunlight. Does not interfere and additional protection from precipitation.
The connectors of the mobile gasholder are standardized so that the device can be recharged using a conventional filling pistol at almost any gas station.
Another important point - regulatory equipment. The device must be placed so as to exclude access to the management for unauthorized persons, for example, for children. It also makes sense to think about the likelihood of theft of the wheeled chassis with a gasholder and take measures to protect it.
Refueling a mobile gas tank can be done in two ways: using a gas tank truck or at gas stations.
This favorably distinguishes the mobile gasholder from the stationary model, for which refueling it is always necessary to call the gas-filling mobile station.
It is not necessary to wait until the tank becomes empty, it is recommended to refuel at a time when less than 20% of LPG from the total volume of the reservoir remains in the gas tank. At the gas station to fill the device, you can use a standard refueling gun.
