Abstract
A pipe ram joint includes first and second couplers that can comprise rings for mounting to the ends of respective pipes or formed in the ends of these pipes. The first coupler can comprise a female ring with a first tooth adjacent to a distal end thereof and a first groove spaced from the distal end. The second coupler can comprise a male ring with a respect second tooth and second groove. When the pipes are rammed together, the first tooth is positioned in the second groove and the second tooth is positioned in the first groove. The couplers have features that reduce the force required to ram the pipe sections together.
