ABSTRACT:
Method and apparatus for double jointing pipe, wherein a first pipe section is moved onto a pipe support roller assembly and moved lengthwise over a boom which carries a pipe clamp and internal welder at its end. A second section of pipe is then moved onto the pipe support roller assembly and moved lengthwise into engagement with the first pipe section. After the first and second pipe sections have been properly aligned and the clamps expanded to hold the pipe sections in welding positions, the pipe sections are rotated simultaneously while both internal and external welds are made simultaneously. A cap weld may also be formed with the pipes clamped as described, or the pipes may be moved to another support roller assembly and the cap weld made while the connected pipe sections are on the second support roller assembly. The methods and apparatus disclosed result in considerable savings as to both the cost of equipment and operating costs.
