In a TV program this year, Jinghai District of Tianjin released a set of data - "The processing capacity of welded pipe in Jinghai District has exceeded 10 million tons, and 1 ton of every 4 tons of welded pipe in China comes from Jinghai."

As the largest welded pipe processing base in China, Jinghai has provided an answer for the traditional industry Ghetto to solve the "growing pains" from the old and biased industrial structure to the transformation of smart, green and extended industrial chain.

Mengxia, Tianjin has been experiencing temperatures exceeding 30 degrees Celsius for several consecutive days. In the past, this was the most difficult season for workers in welded pipe enterprises. The production workshop of Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltd. (hereinafter referred to as "Yuantai Derun") is very comfortable, with the production line running as usual and the workers being calm and orderly.

The production line in front of us has a lot of potential, "said workshop manager Man Shukui, pointing to an extended production line. This advanced welded pipe production line in China can automatically load and unload materials. The products produced have a large diameter and thick thickness, and are generally used in large terminal buildings, exhibition centers, high-speed railway stations, etc.

From the changes in a production line, we can glimpse the transformation and transformation of an industry. In the past, Jinghai's steel industry once faced problems such as overcapacity. Under market pressure, how to achieve high-quality development through transformation and upgrading has become an urgent problem to be solved. Changing outdated processes and eliminating outdated products have become an important step.

Yuantai Derun is one of the leading enterprises in China's rectangular tube industry. In recent years, the enterprise has accelerated intelligent transformation while carrying out technological innovation. For example, the Bosi Testing Center we have built has become the 'smart center' of the enterprise. In the laboratory, from raw material analysis to mechanical testing can be completed, providing reliable data support for product quality. "said Huang Yalian, the director of the company's technology research and development department.

Holding over 80 independent intellectual property rights is the core competitiveness of Yuantai Derun.

To develop the steel industry, Jinghai has paid the price of environmental pollution. Now, when walking through Youfa Steel Tube Creative Park in Jinghai District, various steel tube creative artworks are hidden in the green shade. This national AAA level tourist attraction is built in Tianjin Youfa Steel Pipe Group Co., Ltd. (hereinafter referred to as "Youfa Group").

As the first 10 million ton steel pipe manufacturing enterprise in China, Youfa Group's steel pipe production ranks first among similar enterprises in the country. In the field of environmental protection, it has also been striving to become an "excellent student" in the industry.

Tianjin Youfa Pipeline Technology Co., Ltd. (hereinafter referred to as "Youfa Pipeline") is a subsidiary of Youfa Group, focusing on the research and development of green and environmentally friendly steel plastic composite pipes. These "green products" were born in the company's "national level green factory" and are recognized as "specialized, refined, and new products" by Tianjin.

The company has formed a complete 'green' industry chain, "said Jiang Jisheng, the deputy general manager of the company.

In order to transition to "green", Youfa Pipeline has not only established green control standards in various stages from product design to subsequent disassembly and recycling, but also utilized the existing factory roof in the factory area to build a distributed photovoltaic power station, achieving "spontaneous self use and surplus power grid connection". The wastewater generated during the production process is treated and reused through wastewater treatment facilities.

Green and efficiency can also achieve a win-win situation, "said Jiang Jisheng, as the company has completed its transition from providing general-purpose products to customizing specialized products.

Approximately 50000 tons of welded pipes produced by Daqiuzhuang Enterprise are used in the company's prefabricated products every year. The aggregation of the industrial chain has greatly saved production costs, improved production efficiency, and steadily increased the production capacity and efficiency of enterprises, "said Wang Kai, the manager of the company's administrative department.

The traditional steel pipe industry is working hand in hand with the rapidly developing photovoltaic industry to explore more possibilities. Wang Juan is optimistic about this "blue ocean" and has established Tianjin Ruifengda Metal Products Co., Ltd. (hereinafter referred to as "Ruifengda"), launching a photovoltaic bracket production project.

After several years of rapid development, Ruifengda PV brackets have been involved in Plantation, breeding, animal husbandry and other fields, and are exported abroad. The combination of traditional industries and emerging fields is continuously extending the chain of Jinghai steel pipe industry, increasing added value, and stimulating new momentum in the industry, "said Wang Juan.

Not long ago, Refonda released a new rare earth Weathering steel photovoltaic bracket product at a large-scale photovoltaic exhibition, which attracted many customers' attention. Under strong demand, the company has just expanded a factory building of over 9000 square meters.

How to ensure the high-quality development of traditional industries, the largest welded pipe processing base in China has not yet stopped exploring. Last year, Jinghai had over 500 metallurgical industry enterprises with an output value of over 130 billion yuan. "Focusing on intelligence and greening, constantly exploring more dividends on the industrial chain will lay the foundation for the long-term development of the industry," said Hu Shouqiang, director of the Jinghai District Bureau of Industry and Information Technology.
