Flexible Coupling,Rigid Coupling,Grooved Flange Adapter,Reducing Tee&Cross,Eccentric Reducers,Same Diameter Fittings,Reducer,Flange Spool,Cutting&Rolling Groove Size,Gasket Selection. xxxxx By compare with threaded and welded pipes&#**9; connection,the grooved pipe connection is a innovation as its characterastic of flexible,quick installation and easy maitainess.It has already been accepted by more and more people in the world.&#****8; Grooved pipe connection parts have excellent sealability,the sealing is effected by triplicated sealant between gasket and coupling with safety and reliability. Grooved coupling made of nodular graphite cast iron,because the nodulated graphite is able to reduces the separate effect and stress concentration to base substance,therefor this material&#**9;s strenth and toughness is stronger than cast iron to be form a strong force around the pipe and gaskets. Another characteristic of Nodular cast iron is anti-rusting. It is first choice for pipe sprinkler system and water supply & drain engineering.
