Although there is no definitive answer about how long a water tank lasts, a poly water tank would usually last at least twenty years.
A water storage tank can last 25 years or more if properly maintained, but they are usually only warranted for five years. If the air charge in the tank drops dramatically without proper maintenance, the water tank bladder will expand and rupture, taking the pump with it.
Geographic location, water quality, and the ground the tank is built are all factors that can affect the tank's life expectancy.
Some of the major factors that affect life expectancy are described below.
Chemical Stored: The chemical stored and its operating parameters are the first and most evident factor. Polyethylene tanks are hardened by high caustics, acids, and stress-cracking agents. Both of these chemicals attack the plastic in a mild to moderate way. Chemicals can permeate or dry out the plastic depending on the material, tank construction, and actual resin processing. The operating temperature has a major influence on life expectancy as well. The way the chemical interacts with the plastic changes as the temperature increases. To assist in the battle of each of these factors, grp water tank manufacturers in UAE provide tanks made of various materials and thicknesses.
Installation: The location of your tank is the second thing to consider. Is it safer to be inside, outside, or in a temperature-controlled room? Have you been exposed to UV rays? A UV stabilizer is compounded into almost all polyethylene resins to help shield the resin from being weakened by harmful UV rays. Polycom water tanks in UAE are made with a consistent thickness from top to bottom. This allows more resin to penetrate the tank's roof, where the additional thickness can help block out sunlight.
Venting: This is one of the most often ignored yet vital moves. Poly-ethylene tanks must not be overpressured or vacuumed. Appropriate vent size will often be measured by flow and distribution speeds, but there is no such thing as too much venting. Polycom recommends the largest inlet or outlet of your storage tank with a minimum vent of one and a half. The two major causes of failure in a polyethylene storage tank are pressurization and vacuum.
Piping: Piping is often ignored during the installation of a water tank. Polyethylene, unlike steel, will need to move when filling and emptying. In contrast to steel, polyethylene needs to be filled and emptied. The size of your tank is altered by simple temperature changes outside. Flexible expansion joints are necessary for all sidewall connections. The tank cannot expand and contract with stiff piping, which causes unnecessary stress on the tank to cause leaks and eventual failure. Supporting your process piping is also critical; excess weight hanging from your storage tank will put a strain on the tank and trigger future issues. Often support the piping in a way that reduces tension on it. Expansion joints can shield your tank from process-piping weight, pump vibration, and expansion problems.
What needs to be considered when buying a tank?
Let us take a look at the various things to think about before buying a water tank:
Quantity: The first thing to think about the number of tanks one would need. You know where you will need it and how much you will need it, so buy a Polycom water tank in UAE with the capacity you will need.
Use: You must think about the use of the tank before buying. For example, for personal or commercial use.
Brand: Different brands are available in the market for different items. It is our responsibility to decide if the brand we are considering is worthy of our money.
Material: Tanks are made of various materials, including iron, steel, and a four-layer foam tank made of plastic. Because of its efficient and cost-effective features, the plastic water storage tank is the most common.
Durability: We check the durability of the product before purchasing any asset. Similarly, the water tank's reliability must be weighed before making a buying decision.
