No matter what type of heat exchangers or which industries they are being employed in, eventually all of these units will foul,but hydro jetting heat exchanger can be the best solution .
As deposits are building up on the interior walls of heat exchanger tubes, it an insulating barrier forming on the tube wall that will interfere with heat transfer.
As the heat transfer rate drops, so does the heat exchanger’s efficiency.
This loss of efficiency will not only negatively impact the unit’s production capacity, but will also drive up the cost of the final product.
To reduce this impact and help keep production flowing at peak efficiency, heat exchanger performance must be monitored.
If fouling is identified, the deposits must be removed. Outcomes are always improved when the characteristics of the fouling are determined as soon after performance declines are detected.
Safety of hydro jetting heat exchanger
Now more then ever, safety on the jobsite has become the number one priority of plant management.
A commitment to safety has meant that conventional approaches to heat exchanger cleaning are being reconsidered, while new and innovative cleaning methods have been developed.
Improvements in cleaning technologies using mechanical tube cleaners and low-pressure water provide for very safe cleaning applications with unprecedented results.
hydro jetting heat exchanger with water applications often use from 10,000 to 40,000 or more PSI to remove tube deposits while low-pressure water mechanical methods use under 700 PSI to provide a thorough cleaning.
In addition, low-pressure water mechanical cleaning requires significantly smaller crew sizes than high-pressure water methods.
As an added benefit, low-pressure water mechanical cleaning is done in place; it is no longer necessary to dismantle the heat exchanger and move it to a separate work zone for cleaning.
This reduces the risk of accident, injury and component damage.
Environmental Impact with hydro jetting heat exchanger
When considering the various options available for hydro jetting heat exchanger. The environmental impact of the various cleaning methods must weigh into the selection process.
The amount of secondary waste/wastewater generated by each cleaning method and the ease and cost of disposal of waste is often a concern.
One great environmental and economic advantage of the low-pressure water mechanical cleaning methods is water conservation.
Both the inside and outside of heat exchangers have lots of contamination. These are common problem for heat exchanger especially when dealing with hard-to-clean products. When contamination of heat exchanger increases the heat. Transfer efficiency decrease and a lot of energy wasted brought by the contamination of the heat exchanger. High pressure water jetting can deal with all the problems.
There are two most popular ways of high pressure water cleaning heat exchangers is done by manually or semi-automatic. Due to fatal dangers of working with high pressure water and the increased legislation on safe working with high pressure water. The high requirement for the safety for the operator have become the big sound for heat exchanger cleaning .
Hydro jetting heat exchanger in a quick speed
Time really is money for plants in the processing industries. When a unit is down for maintenance, that unit is not generating revenue.
Giving consideration to the environmental impact of how a heat exchanger is cleaned is important.
However, the reality for many plant managers is that budget constraints will drive the decision-making process on how to clean.
Because new and innovative low-pressure water mechanical cleaning applications require far less unit downtime than the high-pressure water approach.
The time required for low-pressure water mechanical cleaning can be 70% less than high-pressure water methods. This can mean a unit downtime of hours cleaning with mechanical cleaners versus days with hydroblasting.
Hydro blasting heat exchanger versus mechanical tube cleaning
Hydro jetting heat exchanger tubes with 40,000 PSI or more of water pressure has often been the approach plants have taken. however, there are significant limitations associated with this method.
When compared to the footprint required for low-pressure water mechanical cleaning methods, the hydroblasting footprint is sizeable.
Water jetting requires multiple water trucks, cleaning apparatus and pumps on site, as well as a large crew of technicians present to operate the equipment and ensure that the large safety zone is maintained.
In addition, the duration of cleaning is lengthy compared to mechanical tube cleaning because water alone is not the best cleaning agent.
Also, the cleaning components of these mechanical systems are smaller, more specialized and require fewer technicians than high-pressure water methods.
Fewer crew members mean less unit congestion, lowering the safety risk for the labor force and the equipment being cleaned.
Additionally, the environmental impact of mechanical cleaning with low-pressure water is far less than with high-pressure water methods.
It also means less exposure to contaminated wastewater for personnel and nearby aquifers.
Water jetting heat exchanger
Heat exchanger can get clogged up with layers solid deposits easy after many days work . While manual solutions are available, but they are time consuming and cleaning efficiency can’t compare with water jetting pump. Our automatic tools guarantee that operator will liberate the hands. avoiding the impact of high pressure water and control debris within the limited area .
Hydro jetting as powerful cleaning method offers fast and efficient cleaning to provide good results. Water blasting system involves the insertion of a hose into a pipe with two or three cleaning heads.
High pressure water jetting system can clean heat exchanger thoroughly and efficiently. Deposit and other particles can get lodged in the heat exchanger tubing, decrease the efficiency of heat transfer. Any reduction can result in higher expenditures for the operator. Water jetting machine has the ability to keep heat exchanger running at its full efficiency.
Hydro jetting heat exchanger involves a nozzle assembled on the end of a flexible hose which go insider of the tube to achieve cleaning. High pressure water blasting removes scale, rust, residue, and other deposits either the internal or external surface. The waste is washed away by the high pressure water .
Water blasting as the best way for heat exchanger
Heat exchanger, condenser, evaporator tube, pipe cleaning. Till now there is no other method can compare with hydro blasting machine. Watex offers high pressure cleaning machine ranging from 250 bar to 2800 bar pressure for different tube cleaning according to different material. And the flow rate up to 220L/min for big pipe cleaning.
Water jetting have proved the ability to solve impossible cleaning challenges include:
Aluminum tubed furfural heat exchanger cleaning. Removing tenacious coke scale from the tube involving a sensitive mechanical heat exchanger cleaning with small pressure like 500 bar.
U sharp tube heat exchanger cleaning. Removing hard coke from heat exchangers in a short time compared to the cleaning by traditional method.
Chosen the right method for heat exchanger is very important .
Cleaning heat exchanger tube is core to the functionality of heat exchangers. When they become fouled, the result will be a decrease the efficiency for whole of the unit . This affects flow rate, fluid pressure and heat transfer. It need to clean and maintain them regularly in order to ensure a smooth flow for your heat exchanger operation.
There are several method for heat exchanger cleaning
High pressure water jetting as the traditional method of tube cleaning is exactly the best method. It use high pressure water from a nozzle blasts away debris and fouling.
Mechanical tube cleaning uses projectiles
Mechanical tube cleaning uses projectiles to clean tubes rather than water jetting. Heat exchanger cleaning by mechanical has grown in popularity with some advancements in maintenance. Some companies also like this ,due to it easy to maintain and increase the safety .
The type of cleaning method depends on the type and hardness of the fouling in your tube. Not only does the mechanical tube cleaning method do a great job at cleaning out fouling. but it’s faster and cheaper than more traditional methods.
