The invention discloses a pipe clamp casting. The pipe clamp casting comprises a lower fixing sleeve, an upper fixing sleeve is arranged on the top of the lower fixing sleeve, a connecting base is arranged on the surface of the left side of the lower fixing sleeve, and a connecting base is arranged on the surface of the left side of the upper fixing sleeve; a connecting shaft is arranged at the position where the two connecting bases are connected, a fixing lug is arranged on the surface of the right side of the lower fixing sleeve, a fixing lug is arranged on the surface of the right side of the upper fixing sleeve, and a rotary shaft is arranged on the front surface of the fixing lug on the upper fixing sleeve. A fixing piece is added into an installation groove in the upper and lower fixing sleeves, the fixing piece is fixed into the upper and lower fixing sleeves through springs, the fixing piece can extend and retract in the installation groove through the springs, and the size of the inner diameters of the two fixing sleeves can be adjusted so that pipelines with different diameters can be clamped tightly in a pipe clamp, the problem that one traditional pipe clamp only can be used in one pipeline with one diameter is avoided, and the pipe clamp is more convenient to use.
