Abstract: A pipe connecting assembly and method for joining two lengths of steel pipe in the field without the need for welding the connection includes a pair of tubular members both having cylindrical exterior and interior surfaces that substantially conform to the exterior and interior surfaces of the two lengths of steel pipe. At one end of one of the tubular members a male connector is formed. The male connector has a plurality of annular flat and tapered ridges and flat annular surfaces formed thereon. At one end of the other tubular member a female connector is formed. The female connector has a plurality of flat annular ridges and tapered and flat surfaces formed thereon. In employing the tubular members in connecting the two lengths of steel pipe, the ends of the members opposite the male and female connectors are first welded to opposed ends of the steel pipe.
