Abstract
A tensioning apparatus () for applying a closing force across a flange assembly (). The tensioning apparatus includes a shank member () and an annular member () connected to the shank member by an interference fit. The interference fit may be selectively relaxed by applying a fluid pressure (P) to a groove () between the annular member and the shank member. A tensioner () is used to pre-load the shank member by pulling on the shank member while pushing on the annular member while the interference fit is sufficiently relaxed to allow relative movement between the annular member and the shank member. Once the pre-load is established, the interference fit is reestablished by releasing pressure Pto lock the annular member in position for maintaining the closure force across the flange assembly after the tensioner is removed. A lock nut () may be tightened against the annular member to provide additional protection against the release of the pre-load. Seals () may be used to minimize leakage of the fluid used for applying the fluid pressure between the annular member and the shank member.
