<p>A fluid piping system is provided including a stepped conduit (14) having a transition portion (18) formed to define either a concaved or convexed outer surface relative to the axis (22), wherein the transition portion (18) inhibits rupturing while forces are directed upon the connection. In one embodiment, the concaved outer surface is so dimensioned as to fold over and reduce tearing while allowing the piping section to become non-concentric with the axis without rupturing.</p> |
