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, first consider the amount of sulfide, chloride, oxygen, residual chlorine and manganese in the water. Other things that you should be wary of include pH, sedimentation level and temperatures. Some elements are found in high levels in these coolers. The kind of material selected to use in making the devices is determined by the chloride levels.
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 dissolved in water, the compounds formed are highly corrosive. For those who are keen on matters touching on water, you already know that the main water purifier in the world is chlorine. For this reason tube plug manufacturers have to think about how to address the problem chlorine causes to water plugs because its use cannot be avoided. The situation is intensified if the water is hot.
If the pH is below 5 and the amount of air in the H2O is high, thinning and corrosion of the tubes is more likely. This is because the film which offers protection does not form readily. However, if the material used in tube plug manufacture is copper, the problem can be avoided. Brass-aluminum alloy plugs do deliver effective results if the PH is high.
Iron and manganese cause a change in the color of water during deposition. There are some plugs which have no resistance when the H2O flowing therein is fresh. Again, the copper ones are very effective. Basically, the properties of the water that will be flowing through them should be taken seriously when purchasing the heat exchanger plugs.
Sedimentation and mass absorption determines the degree of thermal transfer in these devices. If a protective layer is formed on the inside of the tubes, the level of thermal transfer will be reduced and also flow section degree. Another benefit this offers is resistance to transfer of thermal energy. This is referred to as fouling factor. There are no well-defined methods and formulas of calculating this factor. Many of these values given on the same are just estimates.
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.
