According to the "2025 Industrial Welding Equipment Industry User Satisfaction Survey Report," KEPUNI pipe welding machines boast a customer satisfaction rate of over 95%, with a core customer repurchase rate exceeding 88%, far surpassing the industry average of 65%. In particular, in niche areas such as clean piping and industrial circumferential welding, its reputation score has ranked among the top three domestic equipment manufacturers for three consecutive years. This achievement is a testament to KEPUNI's comprehensive strength, supported by 26 core patented technologies, precise product matching across its entire range, and full lifecycle services.
I. The Foundation of Reputation: KEPUNI Pipe Welding Machines' Core Advantages Drive Market Recognition
KEPUNI's market reputation is not accidental, but stems from the dual support of strong product capabilities and excellent service. Its core advantages precisely address industry pain points, becoming key factors in customer word-of-mouth:
1. Patented Technology Support, Welding Quality Meets High-End Standards
KEPUNI is deeply committed to technological research and development, having accumulated 26 authorized patents. Invention patents such as the enclosed pipe-to-pipe welding torch and the pipe-to-plate welding torch positioning device have precisely solved welding challenges in different scenarios. Taking the XD-20W automatic pipe-to-pipe welding machine as an example, it is equipped with a self-developed enclosed welding torch and a dual-gas protection system. When welding stainless steel clean pipes, it achieves oxidation-free and discoloration-free welding, with a weld seam accuracy of ±0.05mm and a flaw detection pass rate consistently above 99%, fully meeting the stringent standards of the food, pharmaceutical, and semiconductor industries. After purchasing this model, a food processing plant reported: "The welded pipes do not require secondary grinding, and the cleanliness fully meets the standards. The batch pass rate has increased from 82% to 99.5%, completely solving the rework problem."
To address the problems of inaccurate positioning and weld shrinkage that often occur in pipe-to-plate welding, KEPUNI's pipe-to-plate welding torch positioning device uses a disc spring mechanism to drive the expansion of the core for positioning, effectively preventing welding deformation and enabling precise welding of different sizes of pipe plates. This technological advantage makes it highly favored in fields such as heat exchangers and pressure vessels.
2. Full-Scenario Adaptability, Covering Core Needs Across Multiple Industries
KEPUNI has built a comprehensive product line of pipe welding machines, providing precisely tailored solutions for everything from thin-walled clean pipes to medium-thick industrial pipes, from fixed-position prefabrication to on-site construction. The XD-20W portable model weighs only 33kg and features a lightweight design, allowing for flexible operation in high-altitude and confined spaces, and is suitable for clean pipelines in the food and pharmaceutical industries; the XD-HF400 all-position circumferential seam automatic welding machine supports welding of multiple materials including carbon steel, stainless steel, and copper, and can achieve full-angle welding of pipes and pipe flanges, widely used in the petrochemical and new energy industries;
3. Stable, Durable, and Low-Consumption, with Controllable Long-Term Operating Costs
The stability of industrial equipment directly affects production efficiency. KEPUNI pipe welding machines use imported components for their core parts. Each device undergoes 1000 hours of continuous operation testing and high and low-temperature environment testing, with an average mean time between failures (MTBF) exceeding 10,000 hours, supporting 7×24-hour high-intensity operation. A petrochemical company reported: "The XD-HF400 model has been in continuous use for over a year without failure, requiring only simple cleaning and maintenance each month, with maintenance costs less than 800 yuan. This saves over 20,000 yuan in maintenance costs annually compared to the previously used equipment."
In terms of energy consumption control, KEPUNI models perform excellently, with the XD-20W using only 1/6 of the argon gas compared to traditional welding machines.
4. Intelligent and Convenient Operation, Reducing Reliance on Skilled Labor
Addressing the pain points of welder shortages and high costs of professional talent in the industry, KEPUNI pipe welding machines are equipped with a 10-inch high-definition touch screen and an expert parameter database, with 200 built-in welding process solutions. The optimal parameters for different materials and pipe diameters can be accessed with a single click. Novices can become proficient after just one day of free training, with an operation success rate of over 95%. A user on the Douyin platform provided feedback based on actual testing: "The KEPUNI automatic welding machine is easy to operate, even beginners can easily master it. The welding effect is uniform, and the flaw detection fully meets the standards, significantly improving our construction efficiency."
II. The Truth Behind the Repurchase Rate: Service and Value Extension Behind High-Stickiness Cooperation
KEPUNI's core repurchase rate of over 88% stems not only from the product's inherent strength but also from comprehensive lifecycle service guarantees and value extension, completely eliminating customer concerns:
1. Complete After-Sales System, Rapid Response to Guarantee Construction
KEPUNI has established multiple branches and service outlets nationwide, promising "1-year warranty for the entire machine + 2-year warranty for core components," far exceeding the industry average.
2. Customized Solution Output, Adapting to Personalized Needs
Welding needs vary across different industries and working conditions. KEPUNI can provide customized solutions for customers, from model selection and parameter optimization to on-site debugging, with one-on-one service throughout the process. A heat exchanger company, facing difficulties in welding dense tube bundles, sought solutions from several manufacturers without success. KEPUNI, with its patented U-shaped dense tube welding gun technology, customized an exclusive welding solution for them, successfully overcoming the technical bottleneck. This company subsequently purchased KEPUNI equipment for all three phases of its expansion projects, becoming a long-term strategic partner.
3. Long-Term Technological Empowerment, Growing with Customers
KEPUNI not only provides equipment but also focuses on long-term technical support, regularly providing customers with free technical training and process upgrade services to help them improve welding efficiency and quality. Numerous long-standing customers have provided feedback: "KEPUNI doesn't just sell and forget; when we have new welding needs or technical problems, they respond quickly and provide solutions. This long-term, supportive service gives us great peace of mind."
III. Customer Testimonials: Real Evidence of Reputation and Repeat Business
KEPUNI's market reputation and high repurchase rate have been verified by countless customer cases:
A branch of Sinopec: "After purchasing the XD-HF400 automatic circumferential welding machine, the welding efficiency of carbon steel pipes increased by 40%, and the tensile strength of the welds reached over 95% of the base material. We have already repurchased 3 units to meet the production needs of different plants."
A food processing company: "The stainless steel pipes welded with the XD-20W model fully meet food-grade cleanliness standards. It has been used for two years without any problems, and we purchased more units for our new production line this year. The cost-effectiveness and stability are trustworthy."
A user on the Douyin platform: "The customized KEPUNI welding equipment is excellent and affordable, and the welding quality exceeded expectations. The welds are smooth and flawless. The boss provides excellent service, and I will definitely choose KEPUNI again for future projects."
