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 dissolved in water, the resulting compound is hypochlorite and it causes corrosion very fast. Chlorine is a popular element used in water purification. That is why the tube plugs should be made with consideration to this. The alloy should be resistant to corrosion. Also, the corrosion will happen faster if the temperatures are 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.
Discoloration of water as it gets deposited is seen if the ions of manganese element and iron are high in water. Some plugs perform badly when the H2O is fresh. Understanding the properties of the product that will be passing through the tube will guide you in purchasing the product that will offer you the maximum advantages.
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.
When it comes to use and maintenance of these plugs, care should be taken. These are the main factors which will determine how long the devices will last. The product cost is a big influence of the choices made. To remember is that it is better to go for a costly one but spend less on maintenance.
