Resources for Hydraulic Tanks

Hydraulic tanks, also known as hydraulic reservoirs or hydraulic reservoir tanks, are storage tanks that are extremely useful for various applications.

Whether you want to buy or rent hydraulic tanks, or you want to become a hydraulic tanks service provider, you will need to be conversant with certain terms that indicate specifications or types of hydraulic tanks. This guide will familiarize you with key terms related to hydraulic tanks, such as storage tank corrosion, thermal insulation, and relief valves.

Storage tank corrosion

Corrosion is one of the major reasons for failure of hydraulic tanks. Corrosion occurs when a tank made of metal interacts with atmospheric elements.

Corrosive agent

A corrosive agent is a substance that can cause rust or corrosion. In order to prevent corrosion, most hydraulic tanks have a protective coating. Alkaline compounds, acids and salts are the most common corrosive agents. Depending on the location of the hydraulic tank, it may be more susceptible to certain corrosive agents.

Interior liner

To protect the tank metal from corrosion, you will need to install a noncorrosive interior liner made of synthetic materials in the hydraulic tank.

Magnetic plugs

Magnetic plugs are used in oil hydraulic tanks to arrest iron particles. When oil flows from one tank chamber into the other, it passes through a strong magnetic field that attracts the ferrous particles in the fluid. These are useful for applications where inclusion of metal particles in the system fluid is not acceptable.

Thermal insulation

Many hydraulic tanks have thermal insulation to reduce the rate of heat transfer and maintain a lower temperature of the system fluid.

Relief or safety valves

Some hydraulic tanks are equipped with a relief valve to maintain a safe operating pressure. Relief valves control or limit the pressure in a system, which can build up by a faulty process, appliance or equipment failure.

UST (Underground Storage Tanks)

You will require an underground storage tank if you need to store your fluids underground. Maintaining a tank underground is an expensive affair and the possibility of groundwater contamination is very high due to the tank's vulnerability to corrosion.

AST (Aboveground Storage Tanks)

Tanks that store fluids above ground level are aboveground storage tanks. It is easier to maintain an AST than an underground tank. However, these tanks take up more space and can be more expensive.
