摘要： 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 (22, 24) both having cylindrical exterior and interior surfaces that substantially conform to the exterior and interior surfaces of the two lengths of steel pipe (12, 86). At one end of the tubular members a male connector (44) is formed. The male connector (44) 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 (102) is formed. The female connector (102) member has a plurality of flat annular ridges and tapered and flat surfaces formed thereon. The male connector (44) is then press-fitted into the female connector (102) to connect the two lengths of steel pipe together without requiring the welding of the two lengths of pipe to each other.
