Here are some more information for Heat Exchanger:
A five day shut down had been planned at an oil refinery to accommodate traditional pressure jetting and chemical cleaning methods to clean four crude train heat exchangers. Tube Tech challenged this route using an alternative innovative method to overcome the main disadvantages: Difficult to clean with lengthy downtime leading to expensive lost production.
The company was able to clean each bundle in a few hours without chemicals or high pressure water jetting, while the other three exchangers were kept running to maintain continuity of production, effectively 'flat lining' the production output. The cleaning procedure delivered a substantial Kj/C-hr improvement on just one bundle compared to all four bundles previously cleaned with either of the traditional procedures.
Cleaning technology
There has been little change over the decades in the methods and equipment used to clean and de-scale heat exchangers and pipelines. The low-tech approach of high pressure water jetting has kept it as a low skilled job with largely unimpressive and variable results.
Despite being armed with demonstrable evidence of being able to achieve better results than traditional methods, the company has faced an up hill struggle to get its innovative techniques widely accepted. It has not been easy persuading potential clients to consider trialling new techniques designed to improve substantially on traditional water jetting methods.
There has even been outright skepticism that Tube Tech's claims can be substantiated. Persistence and determination were needed to change the industry mind set regarding the effectiveness of current cleaning methods. Long-term maintenance contracts can also act as a barrier to an investigation of the company's advances.
The historical reliance on low tech, low skill water jetting for pipe cleaning has meant that clients have accepted that this is the best that can be achieved. This meant that there was often no quantifiable data against which Tube Tech's improved results could be measured.
Setting out to devise a more scientific approach to the whole cleaning and de-scaling process,
The company has created more than 40 innovative techniques. This has led to several 'firsts' in heat exchanger and pipeline cleaning processes. These developments include:
o The ability to clean exchangers in-situ where previously they were pulled.
o The ability to clean and unblock hairpin bends.
o Speed cleaning difficult bundles in hours instead of days.
o Online cleaning of difficult heat exchangers.
The introduction of more sophisticated technology enables the cleaning and de-scaling to be carried out faster so there is considerably less downtime, and potential mechanical damage to equipment is eliminated. Less waste, dry processes and the elimination of chemicals provides a safer and more environmentally acceptable process.
The company has also taken traditional pigging methods and tailored them to achieve much better results. Operating in a tube and pipe environment from 2mm to upwards of 1m, equipment is modified to suit the consistency of deposit and pipe configuration. A wider variety of deposits can be removed by an innovative drift system loaded into large diameter pipes through a very small aperture which then expands to suit the diameter. It also has the ability to return back down the same line without creating an expensive loop system.
Aluminum tubes
The scale which builds up in aluminum furfural exchangers is notorious for being highly tenacious. The accepted wisdom has been that due to their delicate nature, aluminum hairpin heat exchangers can only be cleaned using 200bar (3625 psi) bar water pressure.
This low-pressure approach only removes 20% of blockages and scale with the additional problem that it tends to compact coke deposits on the U bends rather than remove them. Working with clients sample tubes, Tube Tech's research and development team devised a combined mechanical and water jet system which used 2500 bar ( 40,000psi) to remove coke deposits and improve overall cleanliness to 90%.
The three-stage process included a sensitive mechanical hairpin-cleaning device coupled with exceptionally low volumes of water. First, each tube was cleaned using the Softdrill(TM) lance made from 'intelligent' metals to prevent damage to the tube wall. These soften on entering the U-tube and stiffen on extraction, while an oscillating motion drills the blockage using a mixture of water and an occasional infusion of food grade media at 12 * the pressure and four times the speed of the conventional approach. Finally, a micro turbine rotating under controlled hydraulic pressure was guided through each tube.
Not only were the results substantially improved but also cleaning was carried out in-situ, reducing downtime by 200% and avoiding possible handling damage, the cost of cranage and bundle pulling equipment.
A U-bend first
The inability of traditional water jetting to remove hard coke and oily sludge in the U bends in heat exchangers in crude oil distillation complex has produced a 70% cleaning standard.
After analyzing the nature and composition of the deposit and its dimensions, the Tube Tech approach was used. The result was:
o 99% of contamination removed.
o Hairpins cleaned for the first time ever.
o Heat exchangers returned to virtually as new condition.
o Cleaning operation completed in three times faster than the standard pressure jetting times, down from six to two days.
o Greatly improved throughput.
In-situ cleaning
Solving problems related to specific equipment often enables the company to further improve on its initial performance. The cleaning process for an important tube bundle In a catalytic cracker was initially reduced from nine days to six but this first experience subsequently lowered the barriers further. A smaller sister unit was subsequently cleaning in three hours instead of three days.
For the first time the operation was carried out in-situ, using a new turbine method, incorporating a low-pressure water jetting system avoiding the cost and effort of removing 10t of exchanger gaskets, scaffolding or cranes. In-situ cleaning lengthens the life of the bundles, which deteriorate through damage caused when they are removed for cleaning.
Mike Watson, Managing and Technical Director
Run by its founder and inventive visionary Mike Watson the company is supported by a wealth of hand selected department managers. With many years experience in developing engineered solutions to complex problems in industry, Mike’s belief is that convention should always be challenged in order to find a better way to achieve improved results. This “never say never” approach, led to him founding Tube Tech in the 1980s. Today, the company cleans the toughest cleaning projects the world can throw at it. Mike often says “If people say it can’t be done, its like a red rag to a bull to me. I will always find a solution”. Mike continues to invest in new technology development, leading the world in new cleaning methodology.
Cleaning Your Heat Exchanger Tubes
Cleaning your heat exchanger tubes is a job anyone can do if they know how. If you are a do it yourselfer then you should have no trouble with this task.
There are several methods to clean exchanger tubes. Here are a few of them; one is to use chemicals for the cleaning. Another is to use high-pressure water system. One last method is to employ mechanical cleaning using brushes, scrapers and abrasive balls. These are the best ways to clean the tubes.
Regular cleaning of the exchanger tubes should prolong the life of the entire unit. It will help it work at its maximum efficiency as well.
Many people use a heat exchanger system to heat their swimming pools these days. Having the ability to clean your own exchanger tubes would be a good way to save money and keep your system in top working order.
It would be beneficial to clean the exchanger tubes every few months. At least inspect them to see if they need to be cleaned. If they do not need to be cleaned, and then make sure that, they are thoroughly cleaned twice a year.
In order to clean the exchanger tubes properly, they must be removed from the system. Remove any loose material that is near the ends of the tubes and inside them as well. Use a brush and push it down the tube to get the cleaning started. The brush should have good strong nylon bristles. This helps to loosen and remove any loose materials inside.
During this brushing process, you may find that there is some material stuck to the sidewall of the exchanger tube. A plastic or metal scraper will help to remove anything that is stuck to the wall. Be careful not to damage the tube. Do not use a scraper that is harder than the material of the wall of the tube.
Try not to scratch the wall of the exchanger tubes as it could cause the tube to not function as well as it should because particles could stick to the scratches in the tube. Therefore, a plastic scraper would be best.
As a last step in cleaning the exchanger tubes, you could use a water jet to force out any loose particles that were missed with the previous methods. If you have any calcium deposits on the tubes then you will need chemicals to remove them.
Now you have the basics for cleaning your exchanger tubes. Gather as much information as possible before tackling this do it yourself job.

what can cause a shell and tube heat exchanger to block the flow of steam on the tubes side?
the exh is used to heat a swimming pool and the flow of steam is correct between the boiler and the inlet of the exchanger. Steam does nto flow through the exchanger however. Any ideas as to why this may occur?
*Un till and unless there is a improperly maintained boiler,the quality of steam is good enough.If otherwise boiler will become very in efficient.
As per your data,steam pressure from boiler is OK.
So, we have to look for the steam line connecting from boiler to shell and tube type heat exchanger.
If it is ok , then there is a problem in the shell and tube type heat exchanger.
Above is required for diagnosing the area of concern.
Blockage is nothing but fouling of the tubes or inlet or outlet port of channel box is choked.Check for the blank or blind provided in the inlet for any maintenance purpose.
It is a good practice to have a stream trap in the condensate line for better heat transfer.Steam trap assembly is provided with two nos. of isolation valves and 1 no. of bypass valve.And also there is a suction strainer in the trap itself .
So, check above all for any problem.Open the by-pass valve of the trap and prime the system.Shell and tube type heat exchanger tubes may be filled with condensate if IN-OPERATIVE for a certain period and need to be removed.
Since, this is a swimming pool , there must be a control.Check the control assembly.
There must be a PRV in the steam line going to shell and tube type heat exchanger.
Check whether it is in a good condition or not or simply open the by-pass valve of the PRV.
Lastly , check the extreme out let valve , i mean nearest to the swimming pool. People generally use to close the inlet and outlet valve.
**Seesaw fouling. Here, fouling loading generally increases with time (often assuming a generally linear or falling rate), but, when looked at in more detail, the fouling progress is periodically interrupted and takes the form of sawtooth curve. The periodic sharp decreases in the apparent fouling amount often correspond to the moments of system shutdowns or other transients in operation. The periodic decreases are often interpreted as periodic removal of some of the deposit (perhaps deposit re-suspension due to pressure pulses, spalling due thermal stresses, or exfoliation due to redox transients). However, other reasons are possible, e.g., trapping of air inside the surface deposits during a boiler shutdown, resulting in enhanced steam nucleation (therefore improved boiling heat transfer) during the initial period of subsequent operation.
