From the extreme environment of deep-sea mineral mining to vertical transportation of super high-rise buildings, from efficient construction of municipal engineering to precise operation of nuclear power projects, pump pipes, as the core carrier of material transportation systems, are constantly breaking through application boundaries with technological innovation. Recently, reporters found through research that under the dual driving force of major engineering demands and increased investment in enterprise research and development, China's pump and tube industry has formed a development pattern of "material upgrading, process improvement, and scene expansion". Domestic pump and tube not only achieve comprehensive substitution in major domestic projects, but also rank among the international advanced level in technical indicators.
The high-end field is constantly breaking through, and the core technology is achieving leapfrog development. The technological upgrading of the pump and tube industry is showing a comprehensive breakthrough trend in "sea, land, and air". In the deep-sea field, China Shipbuilding Industry Corporation's 74th Research Institute has recently successfully developed the largest flow coarse particle mineral pump tube system in China's deep sea. After 8 days of extreme testing underwater at 60 meters in Qiandao Lake, the system's flow rate reached 2000 cubic meters per hour, and the overcurrent components did not show significant wear during long-term high-intensity operations. The mineral transport particle size and concentration both broke records, laying a key foundation for the commercial mining of deep-sea polymetallic nodules in China. In the field of construction, Shanghai Construction Engineering Group, Ningbo Construction Engineering Group and other enterprises have intensively deployed research and development of vibration reduction and seismic resistance technologies. Patent technologies such as floor penetrating pump pipe vibration reduction components and vertical pumping damping devices for super high-rise buildings have been successively implemented, effectively solving the stability problem of pump pipes in complex construction environments.

Wear resistance, as the core indicator of pump tube quality, has become a key direction for industry technological breakthroughs. The high-pressure wear-resistant alloy J55 pump tube developed by Yanshan Jiuzhou Pump Tube Manufacturing Co., Ltd. combines special alloy substrates with multiple precision heat treatment processes to achieve a hardness of HRC60 or higher. Its service life is 3-5 times longer than ordinary products in the industry. A single pump tube can support the transportation of over 50000 cubic meters of concrete, far exceeding the industry average level. In special scenarios such as nuclear power and chemical engineering, anti-corrosion specialized pump tubes have passed nuclear industry grade quality certification, achieving stable operation in extreme environments and breaking the previous situation of some high-end products relying on imports.

The application scenarios continue to expand, empowering the improvement of engineering construction efficiency. With the maturity of technology, the application scenarios of pump pipes have extended from traditional concrete transportation to diversified fields, becoming a key support for improving engineering construction efficiency. In the construction of the Jishi Gorge Yellow River Extra Large Bridge, the construction team used pump pipes to inject concrete into the steel pipe arch about 50 meters above the river surface, steadily advancing one steel pipe over 30 meters per day, overcoming the construction difficulties on the cliffs. In the shield tunneling project of Shanghai Taopu Sewage Treatment Plant, the application of pumping excavation scheme further demonstrates the innovative value of pump pipes - by directly connecting the outlet of the shield screw machine to the slag pump, the slag is transported to the ground through the pump pipe, which not only solves the transportation problem in a small space, but also doubles the excavation efficiency compared to traditional slag truck transportation, achieving a daily excavation speed of 16-18 rings.

In the field of water conservancy and flood control, the technological upgrading of pump pipes also plays an important role. The Qilihe Flood Diversion Project in Zhengzhou City adopts the new type of cast pipe interface pump pipe, which provides efficient guarantee for the construction of the flood control system by virtue of its quick installation, self-locking anchorage, anti pulling out and other characteristics. Its stability in extreme rainstorm also verifies the reliable performance of domestic pump pipes. In the projects along the "the Belt and Road", the domestic wear-resistant pump pipes have been applied in batches to major projects such as high-speed railway and bridges, and have been recognized by the international market, relying on the advantages of strong adaptability and long service life.

The collaborative efforts of industrial clusters and the construction of a high-quality development ecosystem are essential for the rapid development of China's pump and pipe industry, which relies on the support effect of industrial clusters. The industrial agglomeration zone represented by Yanshan County, known as the "China Pipeline Equipment Manufacturing Base", has cultivated a group of backbone enterprises such as Jiuzhou Pump Pipe with a sound supply chain system and technology sharing mechanism. Relying on the advantages of the cluster, enterprises not only achieve cost optimization in areas such as centralized procurement of raw materials and component matching, but also accelerate technological transformation through collaborative innovation between industry, academia, and research. For example, local enterprises in Yanshan continue to increase the proportion of research and development investment with policy support such as additional deduction of research and development expenses, promoting overall technological upgrading in the industry.

Industry experts point out that the pump tube industry is currently in a critical period of transformation from "scale expansion" to "quality improvement". In the future, with the integration of intelligent and green technologies, intelligent pump tubes equipped with IoT monitoring functions will achieve real-time warning of wear and tear, while the application of lightweight and recyclable materials will promote the green development of the industry. Driven by the continuous release of major construction demands and technological innovation, domestic pump pipes are expected to occupy a more advantageous position in the global market competition, injecting new momentum into the high-quality development of the equipment manufacturing industry.
