What are Static Pressure Vessels and Their Applications?

August 12, 2014

Static pressure containers are designed to store linear loads, spanning mass and volume differentials that far exceed the ambient pressure characteristics of the material being stored. The reasoning behind this type of fabrication is rooted in safety factors, with a secondary focus on protecting pure contents from contamination.

Pressurizing hazardous materials to a closely monitored static value is a well known method of harnessing the laws of physics to diminish the dangerous and unpredictable characteristics of a chemical fuel, especially if that fuel exists normally in another state. Imagine a simple bottle of soda pop or the closed radiator system threading through the engine compartment of an automobile. Remove the top of the bottle or the radiator cap and there's a dynamic reaction of gases, and, in the case of the car radiator, a sudden change of pressure that alters the boiling point of the coolant. These fundamental laws of physics are harnessed in pressure vessel designs to reduce the potential danger of a highly flammable gas or liquid. The static pressure vessel holds the gas at a certified value, condensing the gas into its fluid state, greatly diminishing its threat.

Therefore, static pressure changes the properties of stored contents, offsetting an evaporative characteristic by condensing a substance, reducing the space the gas or liquid would fill at the standard atmospheric pressure we exist under. Of course, unlike high pressure applications, static pressure containment depends on striking a balance, on removing undesirable transient changes of pressure, swapping those changes for an absolutely flat line. Monitoring gauges and precision valves outfitted with high-end instrumentation play their parts in maintaining this linear characteristic, but it's the design and fabrication of the vessel that's the primary factor in supplying the tensile strength to keep the container's shape and structure during events that may introduce transient change. The material is fabricated and rolled, welded and tested to ensure it doesn't flex during temperature changes or sudden pressure variations.

Applications of a sound static pressure tank employ superlative design and fabrication technology to keep combustible fuel stored at a precise volume, condensed under the laws of pressure theory to keep the chemical, a petroleum product or ammonia byproduct, in a subdued liquid state. Pressure differentials keep grain and farm seed pressurized to keep the agricultural matter from spoiling, fostering a system of agronomy storage that matches any chemical refinery. The same pressurization process spurns the presence of contaminants, a particularly important consideration when storing foodstuff. Note, other factors in farming silos can complicate static pressure vectors, factors that include the drying of the grain. Lower static pressures are used in these circumstances, with extraction fans removing any pressure altering factors.

The twofold benefits of static pressure storage bring safe storage in smaller spaces and contaminant free containment to industry and agriculture. These commercial ventures depend on high-quality constructs, vessels made with predictable and repeatable pressure characteristics, and it's always desirable to layout additional resources in delivering the best parts in this competitive field of engineering.
