ABSTRACT:
A method of sandblasting and coating the interior surface of pipe is provided by the present invention. A plurality of legs extend outwardly from a central mounting plate and are adjustable in length and angular disposition to accommodate different sized pipe. The mounting plate has a central opening for receiving an elongated lance of either a painting or sandblasting tool. The lance carries a collar which is adapted to abut the mounting plate. A spring-biased locking pin on the mounting plate is received by the collar to releasably lock the two plates together.
The method of the invention comprises positioning the aforedescribed device in one end of the pipe and then securing a rope of a length equal to that of the pipe to the device. Next, a lightweight bucket is positioned in front of the device and the rope is coiled inside the bucket. A blast of air is then passed through the lance to move the bucket the length of the pipe. Once this has taken place the device is pulled through the pipe with the rope and the rope is moved to an out of the way location. The device is then moved back through the pipe sandblasting or painting as it travels at a steady rate.
