ZOZEN Boiler is a professional manufacturer of industrial boilers in China. ZOZEN Boiler entered the boiler industry in 1988 and took root in the boiler industry, always taking manufacturing high-quality boilers as its responsibility. Through the wonderful video, we recorded the ZOZEN people who work hard in the front line of production. They always adhere to the quality and create ZOZEN good-quality boiler products. After years of development, ZOZEN Boiler has won a good market reputation by virtue of its reliable quality and perfect service.
ZOZEN full-automatic circular saw machine is mainly used for cutting steel pipes before bending. This full-automatic circular saw machine adopts automatic control, and the operator only needs to input the parameters such as material size and processing quantity, and the system will automatically adjust the complex parameters such as saw blade speed and feed rate (cutting speed) per tooth , to automatically produce the required steel pipe parts.
Welding is a vital work in the process of boiler manufacturing, and it has an important influence on the quality of the boiler. In the production base of ZOZEN Boiler, a professional boiler manufacturer, the front-line welders always ensure the quality of the boiler welding seams with their superb technology and responsible attitude. At the same time, ZOZEN Boiler has introduced the advanced welding equipment to realize the welding automation of the main components such as drums, membrane walls, serpentine tubes, steel frames, etc.
Heat treatment is an essential part of the manufacturing process, involving heating a metal or alloy to a specific temperature and then cooling it to harden the material. In the manufacturing process of boilers, the following pressure components require post-weld heat treatment: alloy steel pressure components and carbon steel pressure components which include butt joints with wall thickness greater than 30mm, the cylinders of internal combustion boilers, and T-joints with tube sheet wall thickness greater than 20mm. As a professional industrial boiler manufacturer, ZOZEN Boiler always strictly follows the boiler safety technical specifications to conduct heat treatment on specified boiler components, which effectively reduces the residual stresses in the material that have been introduced by welding and improves the boiler performance.
The boiler as a kind of common special equipment, the quality, specification and mark of its raw materials should meet the requirements of the applicable material specification. According to the different requirements of various materials purchased, ZOZEN Boiler has established a strict acceptance system to ensure the raw materials in compliance with the material specification and to prevent the unqualified raw materials entering into the production processes. For the safe operation of the boiler, sectional materials will be strictly re-inspected to ensure the boiler pressure strength.
ZOZEN Boiler has an advanced membrane wall production line, and the membrane wall tube arrangement is an important working procedure after the membrane wall is put into production. After the membrane wall is welded, it will be made into various shapes by the draw bench machine.
ZOZEN WNS oil-fired and gas-fired boiler is one of the best-selling series of energy-saving and environmental protection boilers in China. The inside of the boiler consists of large diameter corrugated boiler, threaded smoke tube, and other boiler components.
WNS series gas-fired steam boilers customized by ZOZEN Boiler have the advantages of high thermal efficiency, strong environmental protection performance and automatic operation. It is commendable that the WNS series gas-fired boilers adopt the patented appearance of ZOZEN Boiler (patent No. ZL202030031426), which has beautiful appearance and good corrosion resistance.
