In the industrial cluster of Yanshan County, known as the "China Pipeline Equipment Manufacturing Base", Yanshan Jiuzhou Pump Pipe Manufacturing Co., Ltd. (hereinafter referred to as "Jiuzhou Pump Pipe") stands out with its core advantages of wear resistance, precision, and diversity of products. Its independently developed series of pump tubes and accessories are not only widely used in major projects such as high-speed rail and nuclear power in China, but also in large quantities
Ultra wear-resistant materials break through industry bottlenecks and achieve a multiple increase in service life. Wear resistance is the core indicator for measuring the quality of pump tubes, and it is also a technological highland deeply cultivated by Jiuzhou Pump Tube for many years. The high-pressure wear-resistant alloy J55 pump tube developed by the company is made of special alloy steel as the substrate, and is quenched by inner wall quenching, carburizing treatment, and multiple precision heat treatment processes to form a wear-resistant layer with a hardness of HRC60 or higher. National level testing data shows that the product has a service life 3-5 times longer than ordinary products in the industry in continuous concrete transportation scenarios. A single pump tube can support over 50000 cubic meters of concrete transportation, far exceeding the industry average of 20000 cubic meters. At a high-speed railway bridge construction site, our pump pipes operated continuously for 60 days without damage, while the ordinary pump pipes used before needed to be replaced on average every 15 days, greatly reducing the cost of construction downtime. "The person in charge of the construction party who participated in the project gave this evaluation.
