Leveraging the seasonal drop in temperature during late autumn, fluid transmission pipes have implemented measures to reasonably operate and shut down cooling towers, along with the axial flow fans used for temperature reduction in the pump room, effectively reducing power consumption. According to calculations by professional management departments, this single measure alone has led to a cost reduction of nearly 100,000 yuan per month. In daily production operations, 15 sets of cooling tower fans operate simultaneously at full capacity, with a total power consumption of up to 1600kW per hour, making them significant electricity consumers.
The steelmaking and continuous casting systems have specific requirements for the supply of aqueous media, especially when refining high-quality steel grades. The control of temperature differences in the aqueous media plays a crucial role in stabilizing product quality and facilitating the development of new steel grades.
Furthermore, the reasonable operation and shutdown of fans can be adjusted based on outdoor temperature changes, achieving the goal of reducing power consumption and conserving energy. By proactively communicating with each production line user point, gaining an in-depth understanding of specific water temperature requirements, and determining the most reasonable range, it is possible to satisfy production needs while achieving cost reduction and efficiency improvement. Taking full advantage of seasonal variations and the decrease in outdoor temperatures at night, on-duty personnel conduct real-time tracking and monitoring of aqueous media temperature changes, promptly adjusting the operating fans and minimizing the number of fans in operation. Over the past week, the number of operating fans has been halved, resulting in a corresponding 50% reduction in power consumption.
Regarding the hydrostatic burst strength of spiral welded pipes, comparative tests have confirmed that the measured and theoretical values of yield pressure and burst pressure for spiral welded pipes and straight seam welded pipes are basically consistent, with close deviations. However, both the yield pressure and burst pressure of spiral welded pipes are lower than those of straight seam welded pipes. The burst test also revealed that the circumferential deformation rate at the burst site of spiral welded pipes is significantly greater than that of straight seam welded pipes. This confirms that the plastic deformation ability of spiral welded pipes is superior to that of straight seam welded pipes. Typically, the burst site is confined to within a single spiral pitch, which is attributed to the effective restraint provided by the spiral weld seam on the propagation of cracks.
