Recently, Taigang Stainless Steel Pipe Company successfully developed a batch of large-scale square pipes, becoming the first company in China that can mass-produce square pipes used in the residual heat discharge system of the third-generation nuclear power technology AP1000 nuclear island. It is understood that this product has a large specification and high requirements, with a safety level of nuclear grade 1, making it difficult to manufacture and previously mainly dependent on imports. In order to seize the market commanding height, Taigang boldly committed to extrusion forming. Without any existing experience to refer to, after repeated trials and continuous improvement of the process, they finally successfully produced more than 4 tons of large-scale square pipes, which have been fully delivered recently. Stainless steel square pipes are currently in the process of industrial structure adjustment. If they encounter a sharp drop in steel market prices due to overcapacity, it may be difficult to fully emphasize and call for a unified production reduction or output restriction across the industry. Recent policy awareness or policy signs indicate: some advanced productivity projects and products possessed by state-owned large and super-large national key backbone steel enterprises will not easily reduce production in future industrial structure adjustments. This may mean that companies or capacities need to achieve "survival of the fittest" based on their ability to withstand market pressure, gradually creating an effective competitive environment that truly relies on the market to optimize resource allocation. Relevant industry organizations may not "require" the entire industry to implement a unified "production cut" as they did in the past. Instead, they may take this opportunity to create a true "survival of the fittest" environment to balance supply and demand as well as capacity.
