boiler cyclone pressure part fabrication

The key processing technologies such as steel plate blanking, circling, drum and tube plate drilling adopt advanced CNC machining to reduce the assembly stress and prolong the service life of the boiler.
Steel tube cutting, thread tube pressing and convection tube processing all adopt advanced CNC technology.
Automatic production line.

The welding of important parts like the vertical and circular seams of the boiler, the tubes, the inside of boiler and the flange are all adopted automated welding processes such as submerged arc welding or gas shielded welding to ensure the welding quality. All the vertical and circular seams will be done 100% radiographic inspection.
Tube flange weld adopts robot welding.
The chain grate panel, front and rear smoke chamber panel adopts CNC plasma cutting machine to cut orderly and beautifully.
