On March 21, 2025, Hebei Jingdong Pipe Industry Co., Ltd. successfully ignited the blast furnace to resume production. All cadres and employees focus on the two core tasks of "building the foundation of safe production and winning the battle of ultimate cost reduction", adhere to the "two-wheel" drive of accounting operation and lean operation, and achieve the rapid implementation of various indicators.
Hebei Jingdong Pipe industry set casting pig iron, centrifugal ductile cast pipe, cast iron production and manufacturing in one, is the largest casting pig iron and cast pipe manufacturing enterprises in North China. In the preparation stage for the resumption of production, all units have been connected up and down and made efforts as a whole to steadily promote the integrated operation of the iron pre-production, and the whole process tracking of the raw fuel from the purchase into the plant, quality control, and abnormal disposal has been implemented, actively creating conditions for the stable and efficient operation of the blast furnace for a long period.
After the resumption of production, the company will hold a regular production and operation analysis meeting to explore the potential of cost reduction, actively seek the optimal cost of hot metal, optimize the structure of ore blending and coal blending, and actively explore the optimal path of cost reduction of charge structure on the premise of ensuring that the hot metal meets the standard to provide quality services for the next process. The production line unit will continue to optimize process parameters, fine operation standards, improve equipment accuracy, and strengthen equipment inspection to ensure excellent production process control, and ensure excellent process coordination and physical quality.
01 production line leading high-end technology
Hebei Jingdong Pipe industry adopts the "short process" casting process encouraged by the state, that is, the blast furnace hot metal directly into the medium frequency furnace, after heating, tempering, pouring, annealing, finishing, pressure test, coating, health care and other automatic control production of cast pipes. Products cover DN80mm- 2600mm full specifications, with more than 70 independent intellectual property rights. Casting tube centrifuge adopts "one-button" long tube automatic casting, and the production efficiency is twice that of traditional models. Spheroidization adopts the most stable passivated magnesium top blowing process, which is highly consistent with the technology of European and American enterprises, and the qualification rate of ingredients reaches 100%. Independent research and development of T-interface surface treatment equipment and sling cement coating equipment, production efficiency and running speed to reach the domestic advanced level.
02 Seiko casting pipe through the world
Hebei Jingdong Pipe industry attaches great importance to product quality control, and strictly carries out online testing of tensile strength, product size, appearance quality, water pressure test, lining thickness, etc. The chemical composition adopts Germany OBLF GS1000 advanced spectral testing equipment to test 100% of the centrifuge cast hot metal to ensure high product strength, good toughness, pressure resistance and corrosion resistance. The quality is all in line with and higher than national standards, and has obtained CNAS metallurgical product MC certification.
As a pipe casting enterprise holding the "Health License of Domestic drinking Water sanitation and Safety Products in Hebei Province", the whole production process of Beijing East River Pipe industry is based on the principle of not destroying the ecological environment and not containing harmful substances to human body. The outer body of the cast pipe has a zinc spray layer and high chlorinated resin paint, and the outer anti-corrosion coating can be adjusted according to the engineering needs to meet the normal service life of the pipe. The inner wall of the cast pipe is lined with cement anti-corrosion coating. Under high-speed centrifugal operation, cement mortar forms a uniform, tight and smooth lining on the inner wall of the pipe to ensure that the drinking water transported inside the pipe is protected in every possible way.
Jingdong cast pipe has become the preferred pipe of pressure transmission pipe line, widely used in Three Gorges Group "Yangtze River protection", Tianjin Ninghe District drinking water project, northwest Liaoning water supply network project, Chifeng city around the city water treatment project, Tangshan Qingshui Run city and other major projects, exported to Bangladesh, Yemen and other countries and regions. Selected as a key industrial chain supply chain "white list" enterprises, was approved by the Xiongan New Area Construction headquarters as "designated municipal buried pipe production enterprise", won the title of "National foundry industry quality leading enterprise".
03 Ecological priority green development
Green mountains are always there, green water is always flowing, and the air is always new. Hebei Jingdong Pipe Industry is an A-level environmental protection performance enterprise, A national green factory, and a national AAA level tourist attraction. The production process is equipped with advanced SDS dry desulfurization, SDA semi-dry desulfurization, SCR denitrification and other emission reduction facilities, and the construction of environmental protection centralized control center, a closed material shed with a total area of 45,600 square meters, and is equipped with fog cannons, spray dust suppression and dry fog dust suppression facilities. Now the whole process has achieved ultra-low emissions. Vigorously promote green and low-carbon technology, the comprehensive utilization rate of general solid waste has reached 100%, the waste water has achieved zero discharge, and the indicators of product energy consumption, material consumption, water consumption, and comprehensive utilization of resources have reached the advanced level of clean production.
Kunpeng hit waves from this beginning, colorful clouds long in the new day! The full resumption of production of Hebei Jingdong Pipe Industry Co., Ltd. is an important coordinate of the group's breakthrough against the trend, and sounded the charge horn of the revitalization of the forward. Smooth rough into the road, fight against the dangerous and then start. The company will adhere to the direction of "industrial modernization, high-end products, technology autonomy, and market internationalization", promote production and operation with the overall concept and systematic thinking, focus on extreme efficiency, extreme energy efficiency, extremely low cost, and excellent configuration, draw "concentric circles" and gather "centripetal force" to ensure the realization of the business plan and the jump of key indicators. To the group to hand over a high-quality development of excellent results, create a bright future for Jingdong casting!
