Jinan Heavy Industry Co., Ltd. has successfully launched its 273mm seamless steel pipe production project, a milestone that holds great significance for China's seamless steel pipe industry. The project involved piercing, rolling, sizing, and straightening the perforated red steel pipes, with all four main units completing their operations smoothly.
For many years, domestic manufacturers had to rely on imported equipment for producing 273mm seamless steel pipes. This dependence came at a high cost, with expensive machinery and inconvenient after-sales support limiting production capabilities. After extensive research, Jinan Heavy Industry decided to break into the seamless steel pipe production market, aiming to provide competitive, locally-manufactured solutions.
In April 2006, Jinan Heavy Industry secured a major contract worth nearly 100 million yuan from Jiangyin New Changjiang Group for the 273mm seamless steel pipe production line. This marked a turning point, as the company transitioned from supplying individual machines like straighteners and rolling mills to becoming a full-line equipment supplier.
The Jiangyin project was not only the largest domestic-scale seamless steel pipe production line but also the biggest single contract in the company’s history. To meet tight deadlines, Zhang Xiangdong, the project manager from Jigong, and his team worked tirelessly in Jiangyin since early 2008. Their hard work paid off when, on one day alone, they produced 30 pieces of 219mm steel pipes with a 10cm wall thickness, followed by another 80 the next day. The products were widely praised by local manufacturers and industry experts alike.
“The Jiangyin project is a landmark achievement for Jinan Heavy Industry as it entered the metallurgical equipment sector. It marks a significant turning point in the company’s development. The successful operation of this project officially ended the long-term monopoly of foreign manufacturers in large-scale metallurgical equipment, bringing the technology to a localized stage. For Jinan Heavy Industry, this project carries immeasurable long-term value,†said an internal source.
It is also reported that Jinan Heavy Industry has signed a second 273mm seamless steel pipe production line project with Shouguang Giant Energy Company, further solidifying its position in the industry.
