Key Product
Target Applications:
Designed for heavy industrial enterprises such as chemical plants, cement factories, smelting facilities, and crude oil storage and transportation companies, as well as large-scale municipal pipeline maintenance contractors.
Challenges Solved:
Specifically developed to tackle stubborn deposits that traditional high-pressure water jets cannot effectively remove. Equipped with a high-power electric rotating brush head, the system delivers powerful mechanical scraping action to instantly break down and remove calcified deposits, chemical residues, coke buildup, and solidified crude oil inside pipelines. It effectively prevents production downtime and economic losses caused by pipeline blockages and failures.
Supply Chain & Cost Advantages:
Based in Ningbo, a leading industrial manufacturing hub in China, WELANWORLD has integrated premium suppliers of precision molds and advanced hard materials within a 100-kilometer radius. Thanks to strong local industrial collaboration and large-scale production capabilities, the company eliminates unnecessary intermediate costs. Customers can directly purchase larger quantities of high-quality equipment or longer cleaning lines with lower investment, achieving greater efficiency and value.
How It Works:
The equipment features a one-touch digital control panel, allowing operators to precisely adjust brush speed and power output according to different pipe diameters. The heavy-duty, high-torque electric brush head is inserted into the pipeline, where the system automatically advances and removes stubborn deposits. Operators only need to control the feeding speed at the pipe entrance, enabling safe and efficient cleaning without intensive manual effort.
Target Applications:
Designed for star-rated hotels, large commercial complexes, food processing plants, school cafeterias, professional cleaning service providers, and property engineering departments.
Challenges Solved:
Specifically developed to address common challenges in commercial pipeline maintenance, including grease buildup, hair and organic residue blockages, and difficult penetration through multi-bend pipelines. Equipped with a high-speed rotating electric brush head, the machine thoroughly scrubs and removes thick layers of grease deposits from the inner walls of kitchen drainage pipelines, preventing wastewater backflow and unpleasant odors while restoring smooth pipeline operation.
Supply Chain & Cost Advantages:
Leveraging Ningbo’s highly developed ecosystem of premium core motor suppliers, WELANWORLD significantly reduces import tariffs and international logistics costs. With the same procurement budget, customers can acquire machines with performance comparable to international brands at a more competitive unit price, while expanding the overall equipment capacity of their cleaning teams. This enables higher operational efficiency and greater service capacity with a smaller investment.
How It Works:
The machine features a compact frame design and large-diameter inflatable wheels, allowing a single operator to easily move it through passenger elevators and narrow corridors. Equipped with a specially designed high-flexibility, high-torque flexible shaft and electric brush system, the machine quickly navigates through right-angle bends and complex pipeline structures. With a standard foot pedal control valve, operators can guide the flexible shaft with both hands while controlling the brush motor switch with their feet, enabling safe, efficient, and effortless cleaning of entire pipeline systems by a single person.
Target Applications:
Designed for municipal underground pipeline disaster prevention departments, large industrial facilities with underground enclosed pipeline networks, and engineering inspection companies requiring digital asset management for pipeline infrastructure.
Challenges Solved:
The system addresses the challenges of cleaning deep-buried, high-risk, and long-distance enclosed pipelines where manual access is impossible. It eliminates the risks associated with traditional “blind drilling and flushing” methods that may cause pipeline damage. Equipped with a high-torque electric roller brush, the robot safely removes blockages while transforming pipeline conditions and before-and-after cleaning comparisons into visible, data-driven records.
Supply Chain & Cost Advantages:
As a high-end intelligent system, its digital control modules and mechanical chassis are supported by East China’s highly mature electronics, information technology, and precision machinery industrial ecosystems. This localized supply chain enables rapid delivery while breaking through the traditionally high pricing barriers of this product category, which often costs hundreds of thousands of RMB. With a highly competitive total cost, customers can efficiently build a multi-robot fleet for coordinated operations and undertake larger-scale municipal inspection projects with lower investment.
How It Works:
Operators do not need to enter underground wells or hazardous areas. The robot can be controlled remotely from a ground-based console using a joystick. Equipped with a powerful multi-drive chassis, the robot automatically navigates through pipeline obstacles and sludge after being deployed into the pipeline. It features high-power LED lighting, an industrial-grade panoramic camera, and an adjustable electric brush arm. Real-time images are transmitted back to the ground control station, allowing cleaning and inspection operations to be switched seamlessly. The system can also automatically generate digital comparison reports before and after cleaning.
