Abstract
A novel improvement in a tubular ram device for bi-directional driving of pipe casing, vertically or horizontally, wherein the driving hammer imparts the force to the pipe casing through a bowls-anvil and removable collet, thus allowing driving of sections of pipe casing without removing the tubular ram device or making any physical change to the pipe casing.
