DOUBLE TAPER CONNECTOR

1 . A pipe connection for connecting pipe or terminating pipe, the pipe connection comprising:

a mandrel comprising an insertion portion configured for inserting into an open end of a pipe and comprising a head;

a slip for bitingly engaging an outer surface of the pipe and having a first tapered portion and a second tapered portion; and

a sleeve having cam surfaces for engaging the first and second tapered portions and a head engaging portion for securing the sleeve to the head.

2 . The pipe connection of claim 1 , wherein the first tapered portion and the second tapered portion are parallel.

3 . The pipe connection of claim 2 , wherein the first tapered portion and the second tapered portion are offset longitudinally.

4 . The pipe connection of claim 3 , wherein the first tapered portion and the second tapered portion are offset radially.

5 . The pipe connection of claim 4 , wherein the first tapered portion is a distal tapered portion and the second tapered portion is a proximal tapered portion, wherein the proximal tapered portion is arranged at a larger radial distance than the distal tapered portion.

6 . The pipe connection of claim 5 , wherein the cam surfaces of the sleeve comprise a distal cam surface and a proximal cam nose.

7 . The pipe connection of claim 6 , wherein the distal cam surface is adapted to slidingly engage the distal tapered surface and the proximal cam nose is adapted to slidingly engage the proximal cam surface.

8 . The pipe connection of claim 1 , wherein the head comprises an abutment surface immediately adjacent to the insertion portion.

9 . The pipe connection of claim 8 , wherein the head comprises a sleeve engaging surface.

10 . The pipe connection of claim 9 , wherein the sleeve comprises a threaded nut and the sleeve engaging surface comprises a threaded surface.

11 . The pipe connection of claim 1 , wherein the insertion portion comprises a plurality of sealing slots.

12 . The pipe connection of claim 11 , further comprising an O-ring arranged in each of the plurality of sealing slots.

13 . The pipe connection of claim 1 , wherein the slip comprises a first slip and a second slip, the first and second slips configured for consecutive longitudinal arrangement.

14 . The pipe connection of claim 13 , further comprising a cam ring for arrangement within the sleeve and to engage at least one of the first slip and the second slip.

15 . The pipe connection of claim 14 , wherein the at least one of the first slip and second slip comprises a proximal slip and the cam ring is adapted to slidingly engage the proximal slip.

16 . The pipe connection of claim 15 , wherein sleeve comprises an internal shoulder adapted to advance the cam ring in a proximal direction.

17 . A pipeline for transporting fluid, the pipeline comprising:

a plurality of pipes in fluid communication with one another to transport a fluid;

a pipe connection connecting the pipes at each connection between the plurality of pipes, the connection comprising:

a mandrel comprising an insertion portion configure for inserting into an open end of a pipe and comprising a head;

a slip for bitingly engaging an outer surface of the pipe and having a first tapered portion and a second tapered portion; and

a sleeve having cam surfaces for engaging the first and second tapered portions and a head engaging portion for securing the sleeve to the head.

18 . A slip for a pipe connection, the slip comprising:

a substantially cylindrical inner surface adapted for biting into an outside surface of a pipe and having a plurality of teeth; and

an outside surface comprising a proximal tapered portion and a distal tapered portion, the distal tapered portion being offset radially from the proximal tapered portion.

19 . The slip of claim 18 , wherein the teeth comprise a proximal surface arranged substantially radially and a distal surface angled upward away from the pipe surface and skewed in a distal direction.

20 . The slip of claim 18 , further comprising a longitudinally extending compression relief slots.
