When it comes to selection of the devices to be used in heat exchange, it is the house engineers and designers who have to take action. Also, the tube plugs manufacturers have their role to play. Going about it blindly will give a bad outcome. Water quality, design of the devices and techniques of operating and maintaining the devices affect the choices made. Below is an outlook of facets 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 many a time causes corrosion of converter tubes. To prevent this, protective compounds should be added. Their mode of action should address reduction of amount of oxygen in water. Copper allows are lacking when it comes to protection in water highly concentrated with oxygen. An excellent alternative titanium.
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.
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.
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.
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.
