How is the cooling water for welding equipment recycled?

Stainless steel welding pipe machine equipment or high-frequency welding pipe machine equipment, during operation, needs to use water to cool the pipe materials. This is to allow the welded pipe materials to cool down quickly and reduce the frictional heat between the pipe materials and the mold. Another reason is to clean the surface of the pipe materials. This is a continuous process, but if unidirectional water is used, the water consumption will be very large, which not only increases the operating costs of the enterprise but also increases environmental pollution. Therefore, the cooling water must be recycled.
During operation, stainless steel welding pipe machines or high-frequency welding pipe machine groups require water to cool the pipes. This is done to quickly cool the welded pipes and reduce frictional heat between the pipes and the dies, and also to clean the pipe surface. This is a continuous process, but using unidirectional water results in high water consumption, increasing operational costs and environmental pollution. Therefore, the cooling water must be recycled.
After the pipe making machine starts, the steel strip is gradually formed under the pressure of the die. To ensure welding quality, cooling is generally not performed during the forming stage, but begins after welding. Cooling water is sent from the water tank to the pipe making machine group for spray cooling and cleaning. The cooled water flows from the machine's trough into the ground drain and then back to the wastewater tank. Since the wastewater tank contains a large amount of impurities, it needs to be filtered. The filtered water is then pumped back to the pipe making machine group for reuse in the cooling cycle.
