Outdoor storage tanksAbove ground tanks are used to store gases and liquids at normal atmospheric pressure. These tanks are different from pressure vessels where gases or liquids are stored under other pressures.Like other equipment, however, it also requires constant monitoring to ensure it remains in good condition. Consider the following:

Material options are available

Above ground steel tank construction happen differently, depending on the nature of usage and substance to be stored. These tanks can also be made of concrete, glass, polyethylene, thermoplastic, and reinforced plastic. When special chemicals are to be stored, alternate materials are preferred, which are chemical resistant.

Features of these tanks

These storage tanks have special features, which help conserve stored contents. Experts recommend extra care to prevent spilling. Spillage is not only expensive but might also be unsafe.

One method for containing leakage is to have containment dikes or bunding around the tank. Some tanks come with floating roofs, which fall and rise with the level of the liquids. This decreases the amount of air space above the level of the liquid. The floating roofs can be used in combination with fixed roofs or used as a stand-alone feature. These type of roofs are also essential in refineries where the contents might ignite easily. Some businesses keep LPG, nitrogen, oxygen, and hydrogen in spherical tanks for added safety.

Inspection is mandatory

Following local rules and regulations while concerning tanks and hazardous chemicals is important. Any deviation can cause harm to both, the environment around and the personnel nearby. Businesses or homeowners should always follow the regulation regarding the material of the tank and its structural integrity; otherwise, you might deal with more serious problems.

Most power plants, storage tank terminals, chemical plants, and pharmaceutical plants employ inspections to ensure all tanks are in good condition. These tests are conducted without cutting the tank or degrading the contents in any way.

Testing technologies employed for above ground storage tanks includes, magnetic particle, ultrasonic, electro-magnetic technique, and Eddy current techniques. Besides pitting, cracks, pitting and corrosion, wall thinning are also points for inspection.

Get your tanks in good working condition. It is best to consult qualified professionals, as they will have the necessary knowledge and experience in the field.
