A flanged-pipe fitting for joining the plain ends of pipe is described. The fitting comprises a tubular body having an interior cylindrical chamber with a first and second openings, an annular ridge located between the first and second openings, an annular recess for receiving a first sealing gasket

A flanged-pipe fitting for joining the plain ends of pipe is described. The fitting comprises a tubular body having an interior cylindrical chamber with a first and second openings, an annular ridge located between the first and second openings, an annular recess for receiving a first sealing gasket and an annular flanged portion having a notch for receiving a second sealing gasket. The flanged-pipe fitting is used in conjunction with a gland fitting to join the two ends of the pipe together.

A flanged-pipe fitting for joining the plain ends of pipe is described. The fitting comprises a tubular body having an interior cylindrical chamber with a first and second openings, an annular ridge located between the first and second openings, an annular recess for receiving a first sealing gasket and an annular flanged portion having a notch for receiving a second sealing gasket. The flanged-pipe fitting is used in conjunction with a gland fitting to join the two ends of the pipe together. a second pipe in an end-to-end relationship without disrupting the integrity of the pipe comprising: placing a first collar in a non-surface disruptive condition a fixed distance proximate a joinable end of the first pipe; placing a second collar in a non-surface disruptive condition a fixed distance proximate a joinable end of the second pipe; placing a resilient annular seal over the joinable end of the first pipe and the joinable end of the second pipe; placing a first coupling member around the first pipe, the second pipe and the resilient annular seal and over the second collar and the first collar with said first coupling member extending circumferentially around a portion of said pipes; placing a second coupling member around the first pipe, the second pipe and the resilient annular seal and over the second collar and the first collar with said second coupling member extending circumferentially around said pipes to create a gap between the coupling members when the coupling members are in a coupled condition; and compressively squeezing the first coupling member toward the second coupling member to force the resilient annular seal into a fluid-tight seal around the joinable ends while the first and second coupling members simultaneously force the first pipe and second pipe into coaxial alignment with each other. 10. The method of claim 9 including using a coupling collar alignment guide to position the first collar on the first pipe. 11. The method of claim 10 wherein at least three coupling collar alignment guides are used to position the first collar on the first pipe. 12. The method of claim 9 wherein the first collar and the second collar is welded to said first pipe. 13. The method of claim 9 when the first collar and the second collar are frictionally secured to said second pipe. 14. The method of claim 9 wherein a set of bolts are used to compressively squeeze the first coupling member toward the second coupling member. 15. A pipe coupler comprising: a first coupling member, said first coupling member having a first circumferential pipe alignment surface and a second circumferential pipe alignment surface, said first coupling member having a first collar engaging leg and a second collar engaging leg for maintaining an axial position of said first coupling member, said first coupling member having a sealing trough therein; a second coupling member, said second coupling member having a first circumferential pipe alignment surface and a second circumferential pipe alignment surface thereon, said pipe alignment surfaces of said first coupling member and said second coupling member having a radius of curvature substantially the same as a radius of curvature of the exterior of a set of pipes to be joined so that when said first coupling member and said second coupling member are brought together the set of pipes to be joined are brought into co-axial alignment with each other, said second coupling member having a first collar engaging leg and a second collar engaging leg for maintaining an axial position of said second coupling member, said second coupling member having a sealing trough therein; and a resilient annular seal, said resilient annular seal having a relaxed condition wherein the annular seal is larger than a recess formed by said sealing trough of said first coupling member and said sealing trough of said second coupling member so that when said first and second coupling member are drawn together the resilient annular seal is squeezed into a fluid-tight seal while said collar engaging legs maintain the axial position of said first coupling member and said second coupling member. 16. The pipe coupler of claim 15 including a first collar for frictional engaging a first pipe in a non-destructive manner and a second collar for frictional engaging a second pipe in a non-surface destructive manner. 17. A universal pipe coupler comprising: a first coupling member, said first coupling member hav
