ABSTRACT:
A U-bolt clamp saddle construction is disclosed particularly adapted for applications such as clamping catalytic converter pipe connections requiring a rigid saddle. The saddle clamp is of two-piece welded construction, each piece being formed of sheet steel with a square-sided channel on either side, each piece also having an intermediate web having a semicircular cutout adapted to engage the pipe diameter to be clamped. The outer edges of each of the channels are abutted by positioning the pieces together, which pieces are then welded at weld projections located along the edges and on the web to form a high strength flangeless saddle construction for maximum clearance at installation of the clamp. The square-sided channel allows clearance for weld flash, while enabling standard sized nuts to be used. A tab portion is formed on one of the pieces which is folded about the bottom edge and against the face of the other piece to create rigidity of the saddle during clamping adequate for good sealing pressure while affording sufficient yieldability for optimum interfitting with the pipe connection to be clamped.
