Pallosäiliöt

Pallosäiliöt, often translated as spherical tanks or gas holders, are specialized storage vessels designed to hold liquids or gases under pressure. Their spherical shape is a key design feature, as a sphere is the most efficient geometric form for containing a given volume of fluid under pressure. This is because a sphere distributes stress uniformly across its surface, minimizing the risk of localized failure points that can occur in tanks with flat sides or sharper corners.

These tanks are typically constructed from high-strength steel and are often used for the storage of volatile substances such as liquefied petroleum gas (LPG), propane, butane, and various industrial gases. The high pressures at which these substances are stored necessitate robust construction and precise manufacturing. The spherical design allows for the containment of these materials at significantly higher pressures compared to cylindrical tanks of similar material thickness.

Pallosäiliöt are commonly found in industrial facilities, chemical plants, and at distribution terminals for liquefied gases. Their design requires specialized engineering and manufacturing processes to ensure safety and operational integrity. While their primary function is storage, they also play a crucial role in the safe and efficient handling and transportation of pressurized substances. The maintenance and inspection of pallosäiliöt are critical to prevent accidents and ensure environmental protection.
