The ring joint piping system is an ideal pipe joining  method where pipe is difficult to groove or when grooving  is not the preferred method. First weld a factory-supplied  ring on each pipe end, next mount the rubber gasket over  the pipe ends, place coupling segments over the gasket and  fasten bolts and nuts. 

The Model 1100 ring joint  coupling is supplied with a pair of factory rings. The 1100 is a shouldered type coupling that meets or  exceeds the design and performance requirements of the  AWWA C606 standard.

Standard applications include: Water & waste water treatment plants, mining, pulp &  paper, hydroelectric plants, Co-Gen electric plants, food  and beverage and compressed air. 

Working pressures: 20 Bar / 300 psi (200mm - 600mm / 8’’ - 24’’) (Factory test pressure: 60 Bars / 900 psi) 

The 1100 coupling can be used on stainless steel pipe  where applicable. Stainless steel rings of the same grade as  the pipe should be used and are available as an option.
