Suction Tank Materials and Construction
Suction tanks are usually made up of steel, and the standard size of them ranges from 50,000 to 1,000,000 gallons. Sometimes, in places where the water may freeze due to the temperature, the tanks feature circulated heated water. We also use embedded coils to prevent freezing.
They usually have an open steel tank that is covered with wooden planking. Sometimes, they may also be enclosed and rectangular, also made of steel, with a manhole as well a hinged cover. This manhole provides access to the inside of the tank.
Different Types of Suction Tanks
House tanks are used to store water for the sake of supplying it to the buildings. These tanks must be located at least ten feet above the highest fixture that is to be supplied with water from that tank. The two main kinds of tanks that are used most commonly are wooden tanks and iron tanks.
The wooden tanks are used when the tank is to be placed in a place that is exposed to the atmosphere, like outside the building or on the roof. However, the iron tanks are placed inside the building. The wooden tanks are further divided into two categories, lead-lined, and copper lined wooden tanks.
We help you design and install all types of suction tanks with efficiency and quality.
Iron Suction Tanks : Iron tanks are for placing inside the buildings. One thing that is to be taken care of is that, during summers, the temperature is hot, and the moisture tends to condense on the outside of the walls of the iron tank. If it is not properly attended to, the water will drip down and cause unnecessary puddles and will damage both the floor and the ceiling below.
To prevent this from happening, we recommend placing a drip pan underneath every suction tank.
Lead-lined Wooden Suction Tanks : Lead-lined wooden tanks were used before and now they are not so common. Why?
They owe to the liability of sulfates or carbonates to be dissolved in the water. This poisons the water, especially in the places where soft water is placed inside the tanks. So, the lead lining is only used to a limited extent, but the lead is not used to line the tanks, especially where water is soft.
Copper Lined Wooden Tanks : We don't use copper lining in our design commonly for many reasons. From a chemical point of view, they are not as harmful as the lead-lined suction tanks, particularly when the copper is tinned. However, copper linings are likely to present seams and joints, which pose the risk of leakage.
In some kinds of water, the soldered copper joints tend to disintegrate rapidly, which in turn, causes galvanic or chemical action of the metals.
