TANK BLANKETING

Tank Blanketing, also referred to as Tank Padding, is the process of applying a Gas to the empty space in a storage container. The term storage container here refers to any container that is used to store products, regardless of its size. Though Tank Blanketing is used for a variety of reasons, it typically involves using a Buffer Gas to protect products inside the storage container. A few of the benefits of blanketing/padding include a longer life of the product in the container, reduced hazards, and longer equipment life cycles.

 

The most common gas used in blanketing is Nitrogen. It is widely used due to its inert properties, as well as its availability and relatively low cost. Tank Blanketing/Padding is used for a variety of products including Cooking Oils, Volatile Combustible Products, and Purified Water. These applications also cover a wide variety of storage containers

 

Tank Blanketing/Padding is also used to keep contaminants out of a storage space. This is accomplished by creating positive pressure inside the container. This positive pressure ensures that if a leak should occur, the gas will leak out rather than having the contaminants infiltrate the container.

 

Periodic maintenance checks are recommended to ensure that the blanketing/padding valve is in good operating condition. Debris in the valve or damaged seals are the most likely causes of operating problems. The frequency of routine maintenance necessary for blanketing/padding valves will depend on the severity of the operating conditions. Ideally the valve should be checked within a month of installation and then as determined appropriate after that. At a minimum the valve should be checked annually.
