The blast joint provides durable structural surfaces suitable for gripping with power tools and has a pressure operated hydrostatic driver for maintaining a tight fit between a continuous series of erosion resistant rings. The blast joint is also adaptable to be installed in a pressurized well, using a snubber unit.
