The processing accuracy and welding quality of the tube sheet directly affect the operation safety of the boiler. ZOZEN imported the CNC high-speed plane driller to greatly improve the pipe hole processing precision and the surface finish of the hole, creating favorable conditions for the subsequent expansion process.
Relying on the industry-university-research cooperation and large-scale production, ZOZEN has manufactured more than 400 varieties of specifications of industrial boilers including gas-fired boilers, coal-fired boilers, biomass-fired boilers and thermal oil heaters.Develop up to now, the annual production scale of ZOZEN has exceeded 2,000 sets and 25,000 tph.
