Pipe Coupling Apparatus

摘要

A pipe coupling apparatus adapted to allow for the connection of older, common sewer or drain pipe made of concrete, clay or the like to that of the newer style polymers such as ABS, CPCV, PVC and the like. It accomplishes this through a novel connection method that eliminates having to cut off the bell end of the older sewer or drain pipe and provides for a method of stabilizing the alignment of the two connected pipes. The apparatus incorporates a pipe coupling and a flexible polymer transition sleeve, and depending on the dimensions of the pipes involved, may require an optional spacer seal ring. The assembly time is greatly reduced over the prior art methodologies and the coupled pipes are less likely to leak. It is available in both eccentric and concentric configurations.

主权项

1. A pipe coupling apparatus adapted for the connection of non-dimensionally standardized pipes to dimensionally standardized pipes comprising:
a straight end linear pipe coupling having an inlet section pipe length with a round inlet end defining an inlet cross sectional area, an outlet section pipe length with a round outlet end defining an outlet cross sectional area, wherein said outlet cross sectional area is smaller than said inlet cross sectional area; wherein said straight end linear pipe coupling has a longitudinal axis; and wherein said inlet end has an inlet end midpoint and said outlet end has an outlet end midpoint; wherein said inlet end midpoint and said outlet end midpoints are not collinear on said longitudinal axis of the said linear pipe coupling, and wherein said outlet section pipe length has a non uniform radial taper about said outlet longitudinal axis.
