Steel pipe coupling device for steel pipes
Circumferential grooves (14, 24) are formed on both fitted facing surfaces of a male-female joint of a joint device (A), engagement pieces (30) divided into equal parts inside the grooves being loaded so as to be able to move in the radial direction of the male-female joint. During fitting of the male-female joint, the engagement pieces (30) retract into one groove (24) to allow fitting, and after fitting, the engagement pieces (30) are pushed into the other groove (14) by a coil spring (34)and are positioned across both grooves to prevent separation of the male-female joint in the axial direction. Split pieces (31) of the engagement pieces (30) are supported by countersunk screws (41). Set screws (44) are threaded in at the boundary end part of each split piece to press adjacent split pieces against the groove bottom surface. The engagement pieces are firmly secured in the groove and the vertical direction of the male-female joint is securely integrated.
