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.
L'invention porte sur un raccord pour tuyaux et sur une méthode de raccordement, sur place, de deux segments de tuyaux en acier sans avoir besoin de soudure. Le raccord comprend une paire d'éléments tubulaires (22, 24) ayant tous deux des surfaces externe et interne cylindriques qui se conforment essentiellement aux surfaces externe et interne des deux segments de tuyaux en acier (12, 86). Un raccord mâle (44), formé à une extrémité des éléments tubulaires, comporte une série de nervures annulaires planes et effilées sur lesquelles sont formées des surfaces annulaires planes. Un raccord femelle (102), formé à une extrémité de l'autre élément tubulaire, comporte une série de nervures annulaires planes sur lesquelles sont formées des surfaces planes et effilées. Le raccord mâle (44) est alors emmanché à force dans le raccord femelle (102) afin de relier les deux segments de tuyaux en acier sans avoir besoin de recourir à la soudure.
