Designers, engineers and manufactures of heat exchanger devices are the people responsible for selection of proper materials for the process. Following that, they should consider a number of factors in the selection process. The three main aspects influencing the choice are operation and maintenance processes, the design of the materials and the water quality. Below is an elaboration of heat exchanger tube plugs.
On water quality, consider the temperature, PH, residual manganese and chlorine, sulfide level, chloride level, dissolved oxygen, the water purity and the tendency to form sediments. Ions of iron, sodium, magnesium and calcium are less likely to form deposits and this is why their concentration goes up in coolers of water boilers. The type of alloys used to make the plugs depend on the chloride concentration in the H2O .
Soluble oxygen has a big impact on tube corrosion. Based on this occurrence, it is important to put additives in water to reduce its amount. Sulfates bring this problem too. If you go for tubes which are made from copper or stainless steel when the concentration of oxygen is high, there are likely to disappoint you. They also do not function well if the water passing therein has a lot of dirt. Going for something that has excellent performance will save you the frustrations.
When chlorine is mixed with water, the end product is very corrosive. Since chlorine is the only product which performs well in purification of water, its use is extensive. It is upon the selectors of tube plugs to think of ways to reduce the bad effects hypochlorite causes. One of the ways is adding suitable compounds into the H2O to reduce this effect. The effects are far-reaching if the H2O temperature is high.
Less pH indicates the presence of strong acids. These compounds have high corrosive powers. In addition, alkaline solutions have a similar effect. Ensuring these compounds are not in high concentration in the water can effectively address the situation. The pH should be kept as near neutral as possible.
Manganese and also iron are the main elements behind water discoloration while it is being deposited. Stainless steel tube plugs cannot offer protection when the water is fresh. However, copper ones perform very well. The main determinant of the type to go for is the purpose you want the plug to serve.
Mass absorption or tube sediment are key factors in determination of thermal transfer degree when using heat exchangers. Creation of sediments in the plug inner surface decreases thermal transfer. Additionally, it reduces resistance to thermal transfer and also the level of flow section. The resistance offered is termed as fouling factor. Its calculation is not easy and many are the times estimates are given.
After the purchase of the plugs, it is important to get the details of their operation and maintenance right. This way, the devices will offer you the maximum benefits and they are likely to serve you for longer duration of time. The above mentioned factors influence the product cost significantly but if you get a quality product, the cost of maintenance will be reduced.
