The Different Heat Exchanger Cleaning Methods Available

It is highly important to have a considerable knowledge of the different types of foulants or build-up present in the tubing for effective cleaning of condenser tubes. Depending on the awareness, different approaches could be undertaken. It is now possible to make a thorough heat exchanger cleaning. The results found are worth the effort made. With a small increase in water flow, the money saved on decreased fuel costs would be a considerable amount. Also, if the tubing is kept in a better condition, the equipment will be kept in service for a longer duration.

With proper heat exchange cleaning, it is possible to avoid costly replacement. For good maintenance of condenser tube, there are a good number of methods available,many of which are pretty traditional. One mechanical approach that is resorted to is hydro-blasting and is actually forcing water through the tubing under high pressure.  

Although, it is possible to remove much debris with this method, there are possibilities of some pitting and damages to smaller joints. It is seen that as soon as water starts flowing again, the surface again begin to collect foulant due to the roughness of the surface. Hence, though this method is suitable in most circumstances, it may not be the best method of heat exchanger cleaning always. 

Another method that has been tried includes a cocktail of six different chemical agents, which included a 12% foaming hydrochloric acid solution. The result showed the presence of little surface roughness, but there were concerns about ecological implications. Yet another approach in cleaning involved driving nylon or wire brushes and rubber plugs through the tubing as water is forced at high pressure. The danger of damage done to softer tubing was also considerable, especially copper alloy tubing. 

The mineral crystallization leading to corrosion of crevice by itself can be prevented by the use of clarification process. Recently a much better and safer method of heat exchanger cleaning, which included Boiler tube cleaning, especially during online maintenance, has been tested and found to be quite successful and environmentally-friendly. In this process, plastic scrapers or spring-loaded metal are shot through the system with a force similar to a high pressure water gun. The result is a thorough cleaning of metal without affecting the joints or softer copper alloy tubing. 

Additionally, for special tubing needs, one can use custom designed scarpers. This is widely adopted nowadays and is the most efficient and cost-effective method to clean heat exchanger. There is no damage done to the tubing itself and the cleaning is perfect without any surface roughness. 

Hence, the use of tube scraper cleaning method seems to be the most thorough and effective method nowadays, though offline cleaning could be adopted in some respects.

Sponge Blasting Cleaning Technology - Things You Should Know Before Using It

Industries highly prefer   sponge blasting   cleaning technologies for removing any coating and even for profiling. It is a much safer practice than traditional dust removal procedures. Like any other trending cleaning technology, this one also comes with its benefits, problems, solutions, and application knowledge. Before you use this technology of cleaning in your factories, you need to understand how it works and what clauses are attached. What is sponge blasting, and how does it work? Sponge abrasive blasting technology is a relatively new process of cleaning. It is a favourite alternative to hydro blasting,  pneumatic blasting , or dry-ice blasting technologies.  The process involves the mechanism of blasting synthetic sponge material, embedded within micro-abrasive fragments. It is a safe cleaning technology that assures you of little rebounding or dust formation. Unlike hydro blasting technologies, this is a drier option for cleaning purposes. Even the...

Safe Dry Ice Cleaning Tips - What You Need to Follow

Presently, the cleaning industry is gaining grounds. Every year, its total revenue amounts to nearly $ 168 billion. Well, that’s quite huge! With time, the objectives of the dry ice cleaning companies too are transforming. Currently, they are focusing more on spreading greenery all over the globe. The cleaning now is done in a more sanitary and natural manner. Many have introduced alternatives in the dry ice cleaning process. However, while carrying out the process of dry ice cleaning , there are specific considerations that you need to follow for gaining effectiveness in your cleaning. They are as follows:           Use in a well-ventilated area While you are working in a dry ice blast, a proper amount of ventilation is a must. Generally, the carbon dioxide here rises. Now, if there is no adequate ventilation, you are sure to feel suffocated. Again, if you keep the dry ice in a closed room for more than 10 minutes, make sure that yo...

The Best Way For Narrow Trench Digging With Minimal Debris And Labor

Have you heard about the non-destructive digging method? This is one of the effective methods of digging which is quite fast and cost-effective. This method is also termed as the vacuum excavation . It makes use of a suction machine which is being functioned under high-pressure air or water. Sucker trucks are the most popular and advanced machine which is being used for the excavation method. Benefits of the vacuum excavation Now let’s check why vacuum excavation is much preferred one than others: ·          They are safe for workers and bring no unnecessary injuries to the workers. ·          The method loosens the soil particles and removes them. Thus no damage or loss is brought to any properties. ·          This method can be done at any unreachable place too. ·          Affordable and is the m...
