Applications and Features
Features
Space & cost saving
Vertically mounted seismic isolation flexible joints can absorb displacement through the deformation performance of the seismic isolation flexible joints themselves, saving space & cost.
Ideal for stormwater & drainage lines
Ideal for low-pressure rainwater & drainage lines.
Things to note
- Both pipe lines shall be set with centering
- Tighten bolt for flange diagonally & evenly.
- Pipe side flange face shall be clean & without any harm on gasket face.
- In case of polyvinyl chloride pipe, short pipe made of polyvinyl chloride lining on steel pipe is necessary for horse.
