Serpentine pipes are convection heating surfaces used in boiler economizer, superheater and reheater. As a large boiler manufacturer in China, ZOZEN Boiler has industrial leading production technology and equipment. We have built an automatic serpentine pipe production line from welding to bending. In this automatic production line, automatic argon arc welding technology is adopted for the welding of serpentine pipes, and X real-time imaging is carried out on the welds to prevent unqualified welds from entering the bending process. The welded pipe is conveyed to the serpentine pipe bender through the pipe conveying device, and the pipe bending operation is carried out according to the set size.
ZOZEN SZS series gas/oil-fired boiler adopts the PLC control system, it can automatically control the system by temperature, water level and pressure control. ZOZEN Boiler provides the advanced parts and auxiliaries with the boiler system.
