Spacer ring for fixing onto pipes - consists of annular segments with bridge in two parts
摘要
The spacer ring (2) for use on the outer surface of pipes is made of annular segments (4) each of which has two lateral, space-apart pads (8) joined by a bridge (10) to form a ring. The bridge consists of two parts one in the form of a round bar (12) and the other a ring segment (14) apart from it. A part (16) sticks out from the side pads (8) and has a tranverse hole (18) in which is open towards the inside of the ring (21) by a transverse slit (20). The round bar (12) of another ring-segment part is pressed into the transverse hole via the slot. USE/ADVANTAGE - The spacer ring clings adequately to the ring and is securely fixed and can be used for various diameters of pipes.
