The spray coating device as defined in claim 1, wherein said flexible endless drive member comprises a chain mounted on sprockets for continuous movement in one direction, and said connecting member is mounted between said chain and said carriage for transferring a driving force to said carriage. 3. The spray coating device as defined in claim 2, wherein said carriage has a plurality of rollers mounted on said inner and outer guides to support said carriage for movement. 4. The spray coating device as defined in claim 3, wherein said arms have upper ends pivotally mounted for swinging movement in a generally vertical plane between a closed operative position encircling said pipeline and an open inoperative position for positioning on and off said pipeline. 5. The spray coating device as defined in claim 1, further comprising: an upper frame having rollers for contacting the upper surface of said pipeline for movement of said device along said pipeline, and; a pair of arms pivotally mounted on said frame for movement between a position engaging the outer surface of the pipeline and a position disengaged from the outer surface of the pipeline, each arm having a roller for contacting the pipeline to effect centering of the device on the pipeline. 6. The spray coating device as defined in claim 1, further comprising: a telescoping boom for lifting of said device on and off of said pipeline; and a plurality of hoses for coating material supported on said boom and extending to said device for the supply of coating material for said nozzles. 7. The spray coating device as defined in claim 1, wherein said arms on opposed sides of said pipeline are offset longitudinally from each other, and a connecting member extends between said arms adjacent the lower ends of said arms for connecting said arms together in encircling relation about the pipeline. 8. The spray coating device as defined in claim 1, comprising: an upper main frame on said spray coating device having front and rear rollers contacting the upper surface of said pipeline for movement along the pipeline; an arm supporting frame mounted on said main frame and extending rearwardly therefrom, said arm supporting frame having a pair of opposed end walls and a drive shaft supported on said walls for rotation; and intermediate drive connections between said drive shaft and said flexible endless drive members for driving said endless drive members. 9. The spray coating device as defined in claim 8, wherein said intermediate drive connections include a countershaft for each arm in axial alignment with each other and driven from said drive shaft, said arms being mounted for pivotal movement on the countershafts and said endless drive members being driven from said countershafts. 10. A spay coating device for spray coating an exterior surface of a pipeline and supported on said pipeline for longitudinal movement along the pipeline, said spray coating device comprising: a pair of arcuate arms on opposed sides of said pipeline mounted for movement between a closed operative position encircling the pipeline and an open inoperative position removed from the pipeline; a flexible endless drive member mounted on each arcuate arm and extending for about 180 degrees along the associated arm between opposed ends of the arm; a spray nozzle carriage for each arm operatively connected to an associated endless drive member for movement along said arm between the ends of said arm, each carriage having a spray nozzle thereon directed toward the pipeline for spraying a coating on the pipeline; a main support frame having front and rear rollers contacting the upper surface of said pipeline for movement along the pipeline; an auxiliary support frame mounted on said main support frame and extending rearwardly therefrom, said auxiliary support frame including a hood having end walls; a drive shaft supported from said end walls and having a pair of sprockets thereon; and an intermediate drive mechanism between said sprockets and said endless drive members for driving of said endless drive members and carriages thereon. 11. The spray coating device as defined in claim 10, wherein said intermediate drive mechanism comprise a countershaft for each arm having a pair of sprockets thereon; a sprocket chain between one of said sprockets on said countershaft and one of said sprockets on said drive shaft; and another sprocket chain between the other of said sprockets on said countershaft and a sprocket for the associated endless drive member for driving of said endless drive member and carriage thereon. 12. A coating apparatus for spray coating an exterior surface of a pipeline, comprising: a self-propelled spray coating device mounted on said pipeline for longitudinal movement along the pipeline, said spray coating device having a pair of arcuate arms on opposed sides of the pipeline and a spray nozzle carriage having a spray nozzle thereon mounted on each arm for arcuate back and forth movement along the associated arm; a self-propelled support vehicle mounted alongside said pipeline and moving along said pipeline with said spray coating device, said support vehicle having spray coating components thereon for mixing and supplying the spray coating material to said nozzle for discharge onto the outer surface of the pipeline, and a control panel on said support vehicle for an operator to control the spray coating operation; and a telescoping boom pivotally mounted on said self-propelled support vehicle for lifting said spray coating device onto said pipeline, said boom supporting supply lines for said spray coating material extending between said spray nozzles from said support vehicle; a support frame on said spray coating device having front and rear rollers supporting said device on the upper surface of said pipeline for movement along the pipeline; and a support stand on the ground surface adjacent said pipeline having an upper generally flat support table thereon and being of a length less than the spacing between said front and rear rollers of said spray coating device, said spray coating device when removed from the pipeline being supported on said stand with said frame of said device contacting and supported on said table between said front and rear rollers of said spray coating device. 13. The spray coating apparatus as set forth in claim 12, further comprising: a flexible endless drive member including a sprocket chain for each arm, a sprocket adjacent each end of each arm having said sprocket chain mounted thereon; and a connecting member between said sprocket chain and said carriage for said arm for reciprocating said carriage back and forth along said arm upon movement of said sprocket chain. 14. The spray coating apparatus as set forth in claim 12, wherein said connecting member comprises a pin mounted on said sprocket chain for movement therewith, said pin contacting said carriage in drive relation. 15. The spray coating apparatus as defined in claim 14, wherein said carriage has a plate and rollers thereon mounting said carriage for movement along said arm, said plate having an elongate slot therein receiving said connecting pin for driving of said carriage, said pin at opposed ends of said endless drive member moving along said slot to reverse the movement of said carriage. 16. A spray coating device for spray coating an exterior surface of a pipeline: said spray coating device comprising; a ma
