Internal pipe lineup clamp |
| abstract |
In internal pipe lineup clamp for properly aligning adjacent pipe sections prior to welding, is self powered for all of its operations. All components of the device are mounted in a body portion which includes a compressed air tank to supply the motive means for driving air motors which operate the various components including a pair of powered wheels which propel the device through pipe sections. The device includes a latch which assures proper location with regard to two adjacent pipe sections and two sets of similar radially extending members which come into proper alignment, each set adjacent one end of each pipe section ready to be powered by hydraulic means to be urged against the internal surface of the pipe sections and to form the adjacent pipe sections into a similar and uniform radius. Air motors supply the power for the hydraulic pumps. Sealing means are provided for the area of the pipe section adjacent to the radially extending members so that vacuum may be supplied to this area in order to draw molten welding metal into the space between the pipe section to insure better weld. Also described are means to supply welding flux to the edges of the pipe sections being welded from a position between the radially extending members. Means are also provided to control the amount of vacuum applied to the weld area in relation to the amount of weld area remaining open. Means are also provided to control the presentation of flux to the weld area in relation to the speed of welding. |
