Tanks from 10,000 L Up to 50,000L","LPG Tank Components: LP-Gas (propane, butane, LPG) is transported and stored as a liquid under pressure. In order for your equipment to be able to use the propane1 in your storage vessel (cylinder or tank) it must undergo a phase change (vaporization) from liquid to vapor within the","cylinder, before being combusted by your consuming equipment (BBQ, radiant heater, boiler, process burner, etc.). The rate of natural vaporization in your tank is essentially a function of two factors: 1) ambient temperature; 2) tank size and fill level (\u201cwetted\u201d tank surface area). Each piece of propane consuming equipment has its own requirements as to the amount of vapor that it needs to run properly. Vaporization Requires Energy (Heat) Propane, like water, is a \u201ccompound\u201d with its own set of chemical properties. At atmospheric pressure, water, a substance that we are all very familiar with, boils \u2014 that is to say goes through a","phase change from liquid to vapor \u2014 at 212 degrees Fahrenheit (100 degrees Celsius). Propane, on the other hand, as a result of its particular set of chemical properties, boils at -44 degrees Fahrenheit (-42 degrees Celsius). Therefore, as long as your propane tank is stored in an area that is at least -44 degrees F. (at sea level), the propane in your tank is undergoing phase change, and the pressure will be great enough to give off at least some vapor pressure. Now, to complicate things, the phase change of propane, just like that of water, involves the transfer of energy. You cannot boil water without an outside source of heat from, say, the burner on your stove. Further, the more energy applied (the hotter the","burner), the faster your water is boiled, and the faster it is expelled into the atmosphere as vapor. Similarly, with propane, a warmer ambient temperature (above -44 F) results in a higher rate of vaporization and greater vapor pressure, allowing you to draw more vapor off the top of your cylinder. Based upon this discussion, it should be fairly evident that ambient temperature has a direct effect on the ability to run your","equipment. If your equipment is asking for more vapor pressure than can be provided naturally by ambient heat, it may shut down (or merely provide less heat than you require). Tank Size and Fill Level\u2013the \u201cWetted\u201d Surface of the Tank Now that we have briefly discussed the direct effect of temperature (energy) on vaporization, lets now turn to the effects of tank size and fill level. Let\u2019s continue with the water analogy. Say you have two pots of boiling water, one 2 quarts and another 2 gallons. The 2 gallon pot is going to give off more vapor than the 2 quart pot, so long as the heat being applied is held constant. The same is true for propane\u2013the larger and fuller a tank is (the more \u201cwetted\u201d surface it has), the more heat transfer surface area, and the more vapor it is going to give off.","These two factors, heat and heat transfer area (tank size and fill level), directly affect the natural vaporization rate of the propane in your tank. It should be fairly easy to see that if you are relying purely on natural vaporization in order to run your equipment, you are at the mercy of these two factors.","","Maximum LPG Filling Level 75%","","LPG Tank Types: \u27a2 Aboveground. \u27a2 Underground. \u27a2 Mounted Type.","Using Underground Tank will be for several Purpose: \u2022 Space limitation. \u2022 Avoid the Firefighting deluge system. \u2022 Architectural Requirements.","Gas Meter A gas meter is a specialized flow meter, used to measure the volume of fuel gases such as natural gas and liquefied petroleum gas. Gas meters are used at residential, commercial, and industrial buildings that consume fuel gas supplied by a gas utility. Gases are more difficult to measure than liquids, because measured volumes are highly affected by temperature and pressure. Gas meters measure a","defined volume, regardless of the pressurized quantity or quality of the gas flowing through the meter. Temperature, pressure, and heating value compensation must be made to measure actual amount and value of gas moving through a meter. Several different designs of gas meters are in common use, depending on the volumetric flow rate of gas to be measured, the range of flows anticipated, the type of gas being measured, and other factors.","Troubleshooting \u2022 Divide the LPG Tank capacity always. \u2022 Underground Gas Piping always the Lower service. \u2022 Underground Tank dummy Plugs.!!!!!.

Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded \\\"sacrificial metal\\\" to act as the anode. The sacrificial metal then corrodes instead of the protected metal. For structures such as long pipelines, where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to provide sufficient current. Cathodic protection systems protect a wide range of metallic structures in various environments. Common applications are: steel water or fuel pipelines and steel storage tanks such as home water heaters; steel pier piles; ship and boat hulls; offshore oil platforms and onshore oil well casings; offshore wind farm foundations and metal reinforcement bars in concrete buildings and structures. Another common application is in galvanized steel, in which a sacrificial coating of zinc on steel parts protects them from rust","2- Impressed current In some cases, impressed current cathodic protection (ICCP) systems are used. These consist of anodes connected to a DC power source, often a transformer-rectifier connected to AC power. In the absence of an AC supply, alternative power sources may be used, such as solar panels, wind power or gas-powered thermoelectric generators. Anodes for ICCP systems are available in a variety of shapes and sizes. Common anodes are tubular and solid rod shapes or continuous ribbons of various materials. These include high silicon cast iron, graphite, mixed metal oxide (MMO), platinum and niobium coated wire and other materials. For pipelines, anodes are arranged in ground beds either distributed or in a deep vertical hole depending on several design and field condition factors including current distribution requirements.","\u2022 Vaporizer Set and Back Pressure.","",". \u2022 Drop Lines Isolation Set. \u2022 Gas Box for the Malls. \u2022 Douple containtment Pipes ( Jacket Lines.)","Industrial Usage Factories,manufacturing plant,LPg Boilers and Asphalt plants etc. Heavy duties LPG Gas consumption from 100- 2500kg\/hr.
