The invention discloses a pipe clamp for a steel wire mesh pipe. The tail end of a stroke screw sleeve at the both ends of an upper bracket is provided with a bridle, and one side of the bridle is provided with a stop surface with concave and convex textures; a tension device comprises a base and a steel ball of which the surface has the concave and convex textures, and an accommodation part is arranged in the lengthwise direction of the base, and used for holding the steel ball; a lower bracket is arranged on a stroke screw in a sleeving manner, and the lower bracket is internally provided with a plurality of semicircular movable clamps; the upper bracket is internally provided with a plurality of semicircular fixed clamps fixed to each other; and tension hoops of the fixed clamps are arranged around the tension device, and act on the tension device circumferentially when the tension hoops are stressed by tension. Not only the pipe clamp is easy to operate and maintain, but also the wear of the clamp bracket can be reduced, so that the fiction force is increased, and the bearable tensile resistance of the pipe clamp is improved; and the point-by-point encompassment increase of friction surface loads is avoided , and the effects of skid resistance and improvement of tensile strength are achieved.
