On April 22, walking into the production workshop of Taiyuan Northern Heavy Industry Machinery Co., Ltd., intelligent equipment was running at high speed, robotic arms were operating in an orderly manner, and workers were making every effort to promote the factory assembly and commissioning of four sets of small-diameter seamless steel pipe hot rolling units.
The equipment is mainly used to produce small-diameter alloy seamless steel pipes. It will be shipped to India at the end of this month and will be used in oil and gas exploration, transportation and boiler industries.
“What is being assembled is the first section of the exit table of the φ100mm precision seamless steel pipe hot rolling mill, which determines the accuracy of the pipe wall thickness and is a key part of the equipment. The entire set of equipment is mainly composed of three parts: the main engine, the first section of the export table, and the second section of the export table. They are all independently developed by the company, with a total output value of more than 10 million yuan. This is also the company’s first cooperation with a large steel company in India, laying a solid foundation for further exploring the Indian market.” The person in charge of the company introduced.
Since this year, the company has continued its good development trend: the output value will reach more than 70 million yuan in 2025, and it has received orders of more than 40 million yuan so far in 2026.
Behind the outstanding achievements is the company’s high-quality development path with intelligent manufacturing as the core and technological innovation as the driving force.
Taiyuan Northern Heavy Industry Machinery Co., Ltd. is a fully independent machinery and equipment manufacturing enterprise integrating design, research and development, production, installation and sales. It mainly produces complete sets of seamless steel pipe equipment, plate and strip production equipment, coke oven equipment, coal mining equipment and other series of products. It has core competitiveness in segmented fields.
The self-developed straightening machine has industry-leading performance, with an accuracy more than double the American Petroleum Institute API standard, achieving millimeter-level ultimate control.
With its excellent technical strength and product quality, the company has been successfully rated as a “Specialized, Specialized and New” enterprise in Shanxi Province. Its products not only serve domestic leading enterprises such as MCC CCID, First Heavy Industry Group, Second Heavy Industry Group, Taiyuan Iron and Steel Group, but are also exported to Southeast Asia, West Asia, Russia and other countries and regions.
In recent years, companies have focused on intelligent manufacturing and continued to promote the comprehensive upgrade of production lines to digitalization, intelligence, and standardization.
From intelligent production management, precision CNC boring to automated welding operations, the entire process is integrated with intelligent control concepts.
Relying on the ERP financial management system, SMEs production system, and IoT equipment system, we build a smart production management platform to achieve intelligent scheduling of production plans, efficient scheduling of personnel and production lines, and accurate allocation of equipment and materials.
The smart tool cabinet further simplifies the tool management process and effectively reduces material loss.
In the workshop, a batch of high-end intelligent equipment has become the core support for intelligent manufacturing.
The horizontal machining center tool magazine can clamp 60 tools at the same time, and the robot can complete automatic tool change in 2.5 seconds. The maximum spindle speed reaches 25,000 rpm, significantly improving processing efficiency; the five-axis vertical machining center realizes multi-axis linkage and can flexibly adapt to the processing of complex precision parts such as spherical surfaces; turning and milling compound machine tools integrate turning,
It has multi-process functions such as boring, milling and drilling to build an intensive and efficient production line, which effectively reduces labor costs and improves processing accuracy and efficiency. The large-scale gantry welding robot is equipped with AI intelligent algorithm and cooperates with vision, laser and arc multi-sensors to operate accurately. The welds are dense and well-proportioned, the surface is smooth, and the quality reaches the highest standard of first-level flaw detection.
Adhering to the drive of innovation and the integration of industry and education, the company has set up R&D centers to closely follow market demand, investing an average of about 5 million yuan in R&D funds annually. It continues to deepen process innovation and technological research, and deepens industry-university-research cooperation with universities such as Taiyuan University of Science and Technology and North China University.
At the same time, we will join hands with Taizhong Technical School to build an internship and training base to cultivate high-quality skilled talents, solve employment problems, and create a virtuous cycle of talent training, technological innovation, and industrial development to achieve a win-win situation between education and employment, market and employment.
At present, Taiyuan Northern Heavy Industry has world-leading full-process service capabilities and can provide integrated complete solutions from project plan formulation, product design and manufacturing to installation and commissioning.
The φ864mm seamless steel pipe straightening machine with the largest capacity in China, supplied by the company in a complete set, has been officially put into operation this year; the ten-roller combined steel pipe straightening machine supplied in a complete set has recently successfully completed the thermal load test and entered the trial production stage; the three sets of steel pipe straightening units undertaken this year have completed all design work and are currently advancing the manufacturing process in an orderly manner.
The person in charge of the company said that Taiyuan Northern Heavy Industry will continue to delve into the field of intelligent manufacturing, increase investment in digital transformation and core technology research and development, actively expand product application areas, and fully promote technology iteration and industrial upgrading.
The company will take this Indian project cooperation as an important opportunity to deeply explore Southeast Asian markets such as Thailand and Indonesia, expand overseas layout, continuously improve its core competitiveness and brand influence, provide domestic and foreign customers with more efficient and smarter customized equipment solutions, and inject stronger momentum into the high-quality development of Shanxi’s equipment manufacturing industry.
