Abstract
A new method and apparatus have been developed which inserts and withdraws tubing from pipes without bending or kinking the tubing. Beneficially, the new method and apparatus may be employed to insert and withdraw tubing to depths greater than ever possible before. The method involves using a thruster pig to provide force to inject the tubing, and skate apparatuses to reduce coiling and friction of the tube. Advantageously, the apparatus is portable, easily handled, and adaptable to handle tubing of differing diameters.
