Qingdao Hongchenghong Company has launched a new spray-wrapping equipment, and vacuum equipment shipments have now begun.

Qingdao Hongchenghong Anti-Corrosion and Thermal Insulation Co., Ltd., which has been deeply engaged in the field of pipeline anti-corrosion and thermal insulation equipment for many years, has recently once again drawn industry attention thanks to its technological breakthroughs. The company has officially launched a new-generation intelligent spray-wrapping equipment and simultaneously initiated large-scale shipments of equipment for vacuum-insulated pipe production lines, marking a crucial step in its strategic transformation from a traditional equipment manufacturer to a provider of intelligent solutions.

Technological Innovation: A Leap from Mechanical Control to Intelligent Ecology

The spray-wrapping equipment recently released by Hongcheng Hong breaks through the limitations of traditional equipment, which rely on manual adjustments. By integrating IoT sensors and AI algorithms, it achieves real-time dynamic optimization of production parameters. The intelligent control system equipped on the device can automatically detect changes in pipe diameter and precisely adjust the spray thickness and wrapping angle, boosting the product pass rate to over 99.6%. For example, when processing steel pipes with a diameter of 1200 mm, the system can complete the entire process—from rust removal to spraying—in just 0.3 seconds, representing a 40% improvement in efficiency compared to conventional equipment.

The core components of the equipment feature high-precision bearings imported from Germany and a corrosion-resistant spray nozzle developed in-house. Coupled with a patented winding mechanism, this innovative design effectively addresses industry pain points such as paint wastage and loose tube winding. According to testing, the new equipment can achieve a daily production capacity of up to 1,500 meters per single line—representing a 60% increase over the previous model—while reducing energy consumption by 22%. This remarkable achievement is the result of the company’s decade-long continuous technological accumulation: since its establishment in 2018, Hongchenghong has invested over 30 million yuan in R&D, set up joint laboratories with universities such as Qingdao University of Technology, and has collectively obtained 12 utility model patents.

Vacuum Equipment Shipment: A Milestone in Global Expansion

Along with the launch of new equipment, Hongcheng Hong has simultaneously initiated large-scale shipments from its vacuum-insulated pipe production line. The first batch of equipment, valued at 28 million yuan, has already been delivered to countries along the Belt and Road, including Russia, Egypt, and Kazakhstan. Among these shipments is a customized Model 1680 production line for a Russian energy group, capable of manufacturing ultra-large-diameter insulated pipes with diameters up to 1,680 mm, thus meeting the pipeline construction requirements under Siberia’s extreme climatic conditions.

The equipment used for shipment features a modular design, integrating eight processes—including shot blasting for rust removal, epoxy powder coating, polyurethane foam insulation, and more—through a centralized control system that enables full-process automation. Particularly noteworthy is its vacuum sizing technology: pipe forming is carried out under negative pressure, ensuring that the wall thickness deviation of the product is controlled within ±0.2 mm, meeting the international ISO 21809-3 standard. This technology has already been applied to the China-Russia East Pipeline Project. Tested by the German certification body TÜV, the thermal conductivity of the insulation layer has been measured as low as 0.023 W/(m·K), representing a 15% energy-saving improvement over conventional methods.

Market Response: From Domestic Benchmark to International Competitor

Hongcheng Hong’s transformation strategy is already yielding initial results. In the domestic market, its equipment now covers 32 provinces and cities across China and has participated in key projects such as those undertaken by the National Pipeline Network Group and PetroChina. In the international market, its products are exported to 27 countries, with a market share of 38% in Russia, making it the designated supplier for three of the country’s largest energy companies. According to the 2025 financial report, the company’s overseas revenue accounted for over 45%, an increase of 21 percentage points compared to three years ago.

Industry analysts point out that Hongchenghong’s success stems from its dual-engine approach of “technology plus service.” The company has established a global after-sales service network that can respond to overseas customer needs within 48 hours. Its “equipment leasing + technical托管” model has helped Egyptian customers shorten their project commissioning period to just 90 days. As the company’s general manager stated at the shipment ceremony: “We don’t just sell equipment—we aim to export Chinese standards as well.” Currently, Hongchenghong is actively involved in drafting the ISO international standard for pipeline equipment, thereby promoting the global adoption of Chinese technology.

Future Outlook: Builder of a Smart Pipeline Ecosystem

In response to the global trend of transforming energy pipeline construction toward intelligence and green practices, Hongchenghong has already laid out three strategic directions: First, developing a full-lifecycle management system for pipelines based on digital twins, enabling real-time monitoring of equipment operating data and predictive maintenance; second, researching and developing bio-based, biodegradable coatings to reduce the environmental impact of pipelines; and third, building a cloud platform for pipeline equipment that will connect over 100,000 in-service devices worldwide, thereby establishing an industry-wide big data center.

It has been revealed that the company plans to invest 50 million yuan in 2026 to build a smart factory, introducing 5G+ industrial internet technologies to achieve fully automated operations across the entire process—from raw material warehousing to finished-product shipping. By then, the production capacity of a single production line will exceed 2,000 meters per day, and carbon emissions per unit of product will be reduced by 30%. These initiatives could reshape the global pipeline equipment industry landscape.

From small and medium-sized enterprises along Jiaozhou Bay to a powerful competitor in the international pipeline equipment market, Qingdao Hongcheng Hong has spent a decade crafting a vivid example of China’s manufacturing upgrade. The launch of its new spray-wrapping equipment and vacuum pipe production line not only marks a significant leap forward in the company’s technological capabilities but also signals that China’s pipeline equipment industry is shifting from “catching up” to “running alongside” and even “taking the lead.” Driven by both the “dual-carbon” goals and the Belt and Road Initiative, this Qingdao-based enterprise is using innovation as its brush to draw a new blueprint for global energy infrastructure.
