How Lokring Technology Works
The two metal round pipes are inserted into the outer jacket, and the gap between the two pipes is filled with a special sealing liquid for lokring refrigeration.
The lokring refrigeration tool pushes the lokring forward, forcing the connecting part of the pipeline to produce elastic deformation and tightly fit.
The sealing liquid fills and seals the fine gaps and scratches between the inner and outer pipes, and the centripetal force generated by the lokring and locks the connection parts, so as to achieve a complete sealing and tight connection.
Lokring Refrigeration Process
The lokring refrigeration processing technology is the same as that of Vulkan, which is formed by lathe processing.
Advantage 1: Lathe processing does not need to choose soft materials, and bars with higher mechanical properties can be used.
Compared with peer pressure forming, lathe processing and forming do not have to consider the influence of stress rebound, deformation, and other factors on the structure size after forming;
Advantage 2: The raw material selected by lokring refrigeration has higher mechanical properties. The outward deformation of Lokring caused by the supporting force of the connecting pipe after crimping is basically negligible, ensuring that the pipe size after crimping is closer to the theoretical deformation.
Advantage 3: lokring refrigeration processing is non-mold forming, and the most suitable specification and size can be designed according to the connecting pipe provided by you, and the sample delivery time is guaranteed and the verification cycle is shortened.
When your connecting pipe specification changes, the Lokring inner hole size can also be quickly changed according to the latest pipe diameter size.

Lokring Technology Cost VS Welding Cost
Quality Cost
Welding Cost
1. Flame welding leakage rate: 400ppm.
2. In the traditional flame welding method, an oxide layer will be formed on the outer surface of the pipe.
The corrosive gas in the air will accelerate the perforation of the outer surface and cause leakage. The inner surface of the pipe may fall off the oxide scale and cause the pipeline to block.
3. Welding quality is greatly affected by the welder’s operating level and physical condition, and the product quality stability cannot be guaranteed.
Lokring Technology Cost
1. Lokring technology connection leakage rate: 80ppm.
2. Solder-free connection, no oxidation layer on the pipe surface, to ensure the service life of the system pipeline, and the lokring refrigeration is the same as the pipeline life, completely eradicating the micro-leakage, gradual leakage, and other defects that occur after you use it.
3. Lokring technology mainly relies on equipment crimping to realize pipeline connection, which greatly reduces the influence of human factors on pipeline sealing.
Process Cost
Welding Cost
1. The traditional welding process requires resistance welding of a section of copper pipe at the end of the aluminum pipe, which increases the number of solder joints and high leakage risks.
2. Welding between pipes of different materials requires different welding methods (resistance welding, high-silver welding, high-frequency welding), which is complex and affects production efficiency.
3. The tensile strength and fatigue strength of resistance welding joints are low. At the same time, there is no simple and practical non-destructive testing method for testing indicators such as penetration rate and defective fusion rate, so it cannot be promoted to high-quality occasions.
Lokring Technology Cost
1. A lokring connection point can eliminate a resistance welding point and a section of the copper pipe and a refrigerator can reduce at least two welding points, which reduces the leakage rate of the product in disguise.
2. Lokring technology is easy to operate, the connection points are beautiful, no painting and anti-rust processes after welding are required, which simplifies the working procedure and ensures the efficiency of the assembly line.
3. It has a huge advantage in the connection between metal pipes of different materials (copper-aluminum, steel-aluminum), ensuring the effective implementation of cost-reducing projects such as replacing copper pipes with aluminum pipes.
Equipment Cost
Welding Cost
1. Welding requires a lot of equipment investment, resistance welding machine, welding torch, oxygen pipe, and also need to lay energy pipelines and build ventilation pipes.
2. The cost of equipment maintenance and pipeline maintenance is high every year, and it is easy to cause a long-term shutdown when equipment fails.
Lokring Technology Cost
1. A desktop crimping equipment can realize the expansion pre-installation of the connecting pipe, which can guarantee the supply of at least two production lines.
A two-channel pump station equipment can ensure the crimping operation of two adjacent stations.
2. The equipment failure rate is low, and the key crimping components are easy to replace and maintain.
The hydraulic handle can be kept in place to ensure the orderly operation of the assembly line.
Labor Costs
Welding Cost
1. Proficient welding technology is difficult to develop in a short time, it takes more time and cost to train employees.
In China, we normally train a welding worker for 3 years on average, and costs at least 30,000RMB, not to mention that the welding worker is easy to lose.
2. Skilled welders have higher wages, and even skilled welders take longer to complete a solder joint than lokring crimping, and the faster the welding action, the more difficult it is to guarantee the quality.
Lokring Technology Cost
1. Only need simple training for operators to operate equipment crimping, let’s say,1-3 days, you can have a good skillful worker.
2. Equipment crimping avoids human quality factors and has high-quality stability. The crimping speed can be guaranteed after the skilled operation to ensure production efficiency.
Safety Cost
Welding Cost
1. Under the action of high temperature and strong ultraviolet rays generated by welding, a large number of toxic gases such as carbon monoxide and nitrogen oxides will be produced, which directly endanger the health of welding workers.
2. Most of the refrigerants mixed with air will form an explosive mixture, and there is a risk of combustion and explosion in case of fire.
It is difficult to ensure the safety of welders during the process of filling and sealing, rework, and welding.
Lokring Technology Cost
1. There is no need for fire, no harmful gas and smoke are produced, and the health of employees is protected.
2. Fire-free welding, effectively avoiding the explosive and flammable characteristics of refrigerants such as R290, ensuring personnel safety, and improving the working environment.

How to Make Money with Lokring Technology
For Dealers
Most people think that a good quality air conditioner is the main factor to ensure the good refrigeration effect, that’s right, But the installation of an air conditioner is also important.
There is a saying in the field of household and commercial central air conditioner installation called “three points of equipment, seven points of installation “It can be seen that the quality of the later installation of air-conditioning directly determines the quality of the entire refrigeration system.
At present, an obvious feature of the domestic air-conditioning installation market is that air-conditioning distributors are only responsible for the sales of air-conditioning. The air-conditioning sales process only accounts for 30% of the entire air-conditioning process. What about the remaining 70%?
Of course, the remaining 70% is after-sales. After you sell the air conditioner, you may find an air conditioner installation team on the market to help you complete the air conditioner installation.
But how do you control the quality of after-sales installation of air conditioners? Maybe you have also thought about setting up your own after-sales team, but because of funds and other reasons, you can’t have your own after-sales team, OK, lokring technology is your opportunity.
How to find the right people to form your team?
You must have your ideas. According to Miracle’s experience, you are looking for people who have experience in air-conditioning installation but have not obtained a welding technology license, or young people who have not done air-conditioning installation but want to engage in the air-conditioning installation business.
Why look for young people who have not been engaged in air conditioning installation?
Why look for inexperienced young people
Miracle considers the following points:
1. The lokring technology is simple to use, easy to learn, and has a low failure rate. Young people have more motivation and better learning ability to start their business.
2. Those who have work experience in the field of air-conditioning installation and have a senior technician certificate can get high remuneration in the field of welding.
When lokring technology enters the market, it will replace part of the senior welding technicians, and at the same time reduce the salary level of the senior welding technicians.
Therefore, when they are allowed to engage in the solder-free connection business, they will resist and think that the solder-free connection technology may instead of their jobs, it is opposite to the solder-free connection technology, but for the company or enterprise founder, the solder-free connection technology will be a good way to reduce costs.
How to retain team members?
According to the actual situation of your market, you should have your answer. If you are a central air-conditioning distributor, you can try to replace welding with a non-fire connection, and you can test the installation efficiency of welding and lokring technology.
I believe the comparison between the installation efficiency of the no welding connection and the installation efficiency of welding will be very obvious.
First, the solder-free connection can protect your installers from dangerous gases.
Second, it can improve the efficiency of after-sales service, save your time, and save your customers’ time.
Third, you can train your own after-sales team to take the initiative to accept other air-conditioning installation projects when your business is not busy, so as to further increase your income and increase the income of the after-sales team.
If you are interested or have other questions, you can contact us directly. We believe that our large number of cases can well promote your business success.

If you recently received a major project, congratulations, your business has been more successful. Engineering management has stricter requirements for quality.
How to manage every detail in a complicated engineering project? I think it is difficult. Of course, good project management can achieve 1+1 greater than 2 effects.
What if you can simplify the work content in the tedious work? Yes, Lokring technology can do this.
Now, let us look at what lokring technology can do for engineering contractors?
1. Streamline the team
Are you troubled by not finding a suitable air-conditioning installer after receiving the project? Have you ever thought that one person can install the air-conditioning pipeline with a set of tools? Then you should learn about Miracle’s lokring technology.
In the traditional welding process of air-conditioning pipes, nitrogen, carbon dioxide shielding gas, welding machine, welding rod, and staffing of 4~5 people or more are needed.
Is it cumbersome? You can see how easy we install air conditioners. This video will let you know more.
The Lokring refrigeration tool uses fire-free connection technology to crimp and seal the pipeline, and only one person and one tool kit can be used to install the air-conditioning pipeline in the project. There is no fire in the welding process, no bulky carbon dioxide cylinders, nitrogen cylinders, etc., so it is flexible and lightweight.
The installation efficiency of Lokring refrigeration is 3~4 times that of ordinary welding.
2. Eliminates the need to apply for certificates of fire operation and dangerous goods carrying
Lokring technology does not use fire during the pipeline connection process, there is no fire hazard, and there is no need to apply for cumbersome open flame use certificates.
At the same time, there is no use of flammable and explosive materials, which greatly reduces the risk of engineering construction, improves the quality of the project, and increases your influence.
3.Open source and reduce expenditure
Open source: Lokring technology has no safety hazards and does not require open flame construction. To a certain extent, it can increase your bidding chips and have more opportunities to obtain engineering installation projects.
Using lokring technology to save labor costs, can reduce the use of senior welders, and use the reliability of tools to replace expensive labor.
lokring technology saves time when installing air-conditioning than traditional welding, shortens the engineering cycle, wins customers’ trust, increases corporate image, and increases your income. At the same time, it can better win engineering bids.
Throttling:
Lokring refrigeration has a longer service life than welding, which reduces post-maintenance, thereby reducing post-maintenance costs.
Using lokring technology to connect the pipes, the inside of the refrigeration system is cleaner, there is no welding slag, and the impurities in the entire refrigeration system are reduced, which can effectively protect the refrigeration unit and reduce the failure rate of the refrigeration unit.
Extend the service life of the expansion valve solenoid valve and other refrigeration valves, and avoid the loss of the unit shut down due to blockage of the refrigeration system.
Lokring Installation
Lokring Installation for Lokring Fitting
The installation of the lokring refrigeration fitting is very simple. The installation method of the Manual propress tool is introduced below.
First, measure the outer diameter of the pipe before the Lokring Installation, select the corresponding size of the lokring refrigeration according to the outer diameter of the pipe, and then use the pipe cutter to cut the Pipe, (note: when cutting the pipe, the pipe should be stuck between the roller and the blade of the pipe cutter, and with the axial rotation of the pipe cutter, the feed rate of the pipe cutter should be gradually increased).
After the pipe is disconnected, use a trimmer to deburr the inner wall of the pipe.
Lokring fittings are pre-installed after the pipe is cut and marked accordingly.
Use Sealing Liquid to smear the surface of the pipe while rotating the lokring refrigeration to fully seal the gap with the sealing liquid, thereby making the lokring installation firmer.
Finally, use the lokring refrigeration tool to crimp it into place to complete the lokring installation. Read More.
Lokring Installation for Single Ring
The installation method of a lokring single ring is similar to that of lokring fitting. The use scene of lokring single ring is the refrigerator production line.
At present, a lokring single ring is mainly used in scenes where the outer diameter of the pipe is relatively small and the installation speed is high.
The installation of the Lokring single ring is simpler, which further simplifies the installation method and is suitable for use on the production line.
First, select the appropriate Lokring equipment in the assembly line position. According to the production line production needs, equipped with different sizes of lokring refrigeration.
When using, the operator can hold the sealing liquid in one hand and the handle of the operating equipment on the other hand.
