Typically, used storage bullet tanks on the other hand can be readily relocated, refurbished, and sold at attractive market rates.
One advantage to spherical vessel construction is that the stress concentration for stored LPG is both more uniform and lower than that within a cylindrical shaped bullet. Also, because they have a smaller surface area per unit of volume, the quantity of heat transferred from warmer environments to liquid stored, will be lower than that of bullets.
However, the chance of failure and collapse for a large spherical vessel is greater than that for bullet tanks, as the overall load - for an equivalent volume of liquids stored — is concentrated in a single vessel rather than being distributed over a larger area as when stored within a battery of smaller sized tanks serving the same total volume.
The use of multiple storage bullets also reduces the possibility of uneven settlement—another potential cause of vessel failure—again, by dividing the overall load into lesser volumes. Particularly for geographies prone to natural disasters such as earthquakes, hurricanes or tsunamis, including islands and areas where powerful colliding warm and cold air masses and resultant tornados are more common, a battery of multiple storage tanks offers lower risk of failure than large-scale spherical storage vessels.
One of the strongest arguments in favor of choosing a battery of bullet vessels over one or more spherical vessels when possible, is the consideration of ongoing maintenance—including both planned and unexpected shutdowns. With tank batteries, any maintenance or repair issue that calls for the shutdown of a tank is limited to the tank involved. The particular tank can be shutdown and repaired while the remaining tanks continue at full operation.
With the use of larger capacity spherical storage, the shut down of a single vessel can halt operations entirely, leading to potentially astronomical additional costs associated with halting both incoming and outgoing product. Further to this, if it becomes necessary to empty the vessel at hand, the contents of a smaller size bullet vessel can be fairly quickly deployed to another vessel on site.
The task of addressing upwards of a million s of gallons of LPG within a single spherical vessel on the other hand, is a far more onerous task, with an extended period of shut-down to be expected. When space allows, bulk bullet tank storage provides an ideal solution for supporting high levels of LPG consumption—while supporting faster project delivery, lower overall risk, ease of ongoing maintenance and operations. Our above ground storage tanks are available in an array of sizes of up to , gallons and more.
For large installations and terminals, multiple tanks can be linked together to serve any need. Underground tanks are also available.
We also offer custom engineered and turn-key solutions and services for LPG storage and transfer including bulk plant and terminal design , engineering and construction; both new and used LPG storage bullet tanks ; custom vessel specification, design and fabrication; logistics coordination; field services including installation and training; field maintenance; startup and commissioning. Use of open cell or fibrous insulation systems can have severe adverse safety of your sphere, resulting in absorption of flammable liquids, and the danger of wicking which could lead to auto-ignited fires.
The impermeability will make sure that no moisture can penetrate the system or flammable liquids are soaked up by the material creating fire hazards. Spherical storage tanks. Storage tanks, Spheres, Vessels. Controlling Permeability and Moisture Absorption.
