History Of Grooved Pipe Fittings

Ductile Iron Grooved Fittings commonly used to join pipes in both wet (fluid carrying) and dry systems. They allow for some flexibility and movement in the piping system by providing deflection capabilities. When consider the materials of it, we may refer to ductile iron grooved fittings.

The concept of the grooved coupling was as pioneered in 1925 when Victaulic introduced the first mechanical coupling design. This innovation helped provide pipe systems with flexibility and the ability to cope with changes in positioning or movement of the connecting pipes.

Grooved couplings allow piping networks to absorb thermal expansion, seismic activity, and other forces that could otherwise damage a rigidly connected system over time. Victaulic’s original grooved coupling invention laid the foundation for a pipe joining method still widely used today for its advantages of flexibility, reliability and vibration resistance.

Leading YINUO Ductile Iron Grooved Fittings Manufacturer

  • Yutian Yudong Foundry Co., Ltd. was established in 1990.
  • In 1995 Yudong manufacturer began developing malleable steel pipe fittings, helping to expand their product lines and also wholesale to oversea.

4 Components Of Grooved Pipe Fitting

There are four primary parts that comprise a standard grooved coupling:

Grooved Elbow
The pipe section that has been machined or rolled with grooves to accept the coupling hardware.

Coupling Housing
The cylindrical sleeve that connects the two pipe sections.

Sealing Element (Gasket)
The elastomeric gasket compressed between the pipe groove and housing to create the seal.

Consisting of a nut and bolt, this component draws and compresses the housing over the gasket to complete the mechanical joint between pipe ends.
