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.
The advanced CNC plated rolling machine introduced by ZOZEN Boiler can finish the rolling in one time. This machine is used to roll the steel plate into a circle. Also, the vertical lathes is used to process the groove of boiler drum head to ensure a smooth transition.
ZOZEN Boiler is an industrial boiler manufacturer specializing in boiler design, manufacturing, sales and after-sales service, and has obtained international certifications such as ASME, CE, DOSH and so on. The company's advanced production technology and equipment not only shortens the boiler production cycle, but also directly improves the manufacturing quality, with low maintenance rate, which is widely praised by users.
Chain grate is the combustion equipment of chain grate boiler. Coal, biomass and other fuels complete the combustion process on the chain grate. ZOZEN chain grate boiler covers the capacity of 2-75 tons, with a pressure of 1-5.4MPa. The fuel is suitable for biomass granules, anthracite, etc., and it has the characteristics of excellent quality, stable performance and high degree of mechanization. Welcome to consult.
The membrane tube wall racker is an important part of the common boilers, such as ZOZEN SZL series biomass-fired boiler, SZS series gas/oil-fired boiler and circulating chain grate boiler. The racker can ensure the air tightness of the boiler and improve the thermal efficiency.
The boiler of 6-35t/h is composed of 2 main components. The upper assembled component is the body heat accepting part, and the lower assembled component is the combustion equipment. The former part of the boiler body is arranged with a water cooling wall, the upper part of it is connected to boiler cylinder, and its lower part is connected to collective chest, so as to form a combustion room and absorb the radiated heat from the furnace.
The advanced automatic production line in ZOZEN Boiler modern workshop not only shortens the manufacturing cycle of the boiler, but also improves the quality of the boiler and prolongs its service life. At the same time, orderly production management and strict quality inspection are also important components of boiler lean manufacturing. Through the advanced sales model of live streaming, the strong strength of ZOZEN Boiler is transmitted to overseas users.
Welding is a necessary process for the manufacturing and processing of boiler equipment. Different welding processes are adopted according to the different materials. ZOZEN Boiler adopts advanced welding technology scientifically and reasonably. According to the process standard, flame heating will be used for preheating before welding, to reduce the cooling speed of welded joints. It effectively prevents welding cracks.
