Knowledge On Heat Exchanger Tube Plugs

By Daphne Bowen


Architects and designers of products for use in heat exchange system in houses are the people who should choose the type of devices to use in the systems. Manufacturers are not to be left out. They have a role to play. The main things to look out for include the characteristics of the water, the ways in which the devices are operated, maintenance costs and the product design. Read on to know more about 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 .

Oxygen that has dissolved in water makes the tubes corrode faster. This is why it is important to add substances to bring down the oxygen levels in water. Copper alloy tubes are not very effective when the water has high oxygen concentration. In addition, they are not resistant to dirty water when sulfate is present. The best plugs to go for in such a situation are the ones made from titanium and stainless steel.

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.

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.

Sedimentation process and absorption of mass are very crucial aspects in thermal heat transfer. Maximum protection is offered if an inner lining is formed on the tube plug. Thermal transfer is controlled and the flow rate in the section. There is more resistance offered to the product flow. This is known as fouling factor. The formulas put forth to calculate it are not so effective and many times the figure is just an approximate.

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.
