Abstract
A pipe system can include a coupling having an axis, axial ends and a bore. Each axial end can include a coupling spline groove formed in the bore, and a seal groove axially inboard of the coupling spline groove. The seal groove can be configured to house a seal. At least two pipes can be configured to be inserted into different axial ends of the coupling and be secured therein with retainers. Each pipe can include a pipe spline groove, a band groove axially adjacent to and radially shallower than the pipe spline groove, and a band mounted in the band groove.
