ABSTRACT:
A saddle pipe clamp is disclosed of the type including a U-bolt cooperating with a saddle member receiving the ends of the U-bolt which are adapted to apply a clamping pressure about the periphery of a pipe section by means of a pair of nuts threadably engaging the ends of the U-bolt, drawing the outer portion of the U-bolt towards a radiused inner contour of the saddle member. A folded sheet metal saddle member is constructed from a sheet metal blank folded into a three layer stack and spot welded together to form a unitary clamping saddle member. Formed end sections of the blank provide eyes for receiving the U-bolt ends. The middle layer is formed with a slightly smaller pipe engaging radius so as to act as a pressure ridge for sealingly deforming the pipe sections during clamping of the pipe joints. The outer contour of the saddle member is also radiused to minimize the envelope of the assembled pipe clamp without compromising the rigidity of the saddle member to the clamping forces.
