ABSTRACT:
An automatic pipe testing unit adapted to be mounted on a goose-neck trailer and comprises a longitudinally extending rectangular tubing main trailer frame. A test fluid holding tank mounted on the frame has a screened opening to receive test fluid which is drained from each joint after it has been tested, so that the fluid can be continuously recirculated. Also included are hydraulically operated two lift arms and two pipe advance arms, the lift arms each having an integrally attached bevelled finger plate onto which a plurality of pipes can be rolled. The lift arms lift the pipes from one point to a slanted storage area on the top of the unit and herefrom automatically by operation of the hydraulic pipe advance arms, the pipe to be tested is advanced into a pipe gripping vise for testing. The hydraulically operated pipe advance arms can then be operated to eject the pipe therefrom into another area for draining the pipe of all of the test fluid so that the test fluid can be recirculated for subsequent use. The unit is further provided with end plates each having a sloped storage area for a multiple number of pipes to be tested, a U-shaped position to hold a pipe in position to be tested, a position to hold the last pipe tested while it drains all fluid contained therein back into the receiving trough and a ramp to allow the pipe to roll off after it has been ejected from the drain position.
