Pressure data sheet for T-type centrifugal ductile iron pipes (Grade K9)
T-type joint:
T-joint has simple structure, convenient installation and good sealing performance. The contact pressure generated by the compression deformation of the apron plays a self-sealing role, and the hard rubber part of the apron plays a role in fixing and centering. The interface can realize deflection, adapt to certain foundation settlement and realize long-distance steering installation.
Main application fields of ductile iron pipes:
- Urban water supply and distribution network
- Municipal reclaimed water
- Municipal and industrial sewage pipe
- Agricultural irrigation pipe network
- Drinking water pipe
- Industry (papermaking, thermoelectricity, textile)
- Small hydropower station
- Urban heating pipe network and cooling pipe network
