The GD Engineering brand manufactures the Bandlock™2 Closure with integral flanged connections.
These can be fitted to new or existing installations and quite simply replace a blind flange. They are ideal for installations where the operational overhead for opening an existing blind flange is found to be uneconomical over the life of the installation.
Blind flanges are often fitted because they provide lower cost on capital investment at the initial construction phase. It may not be until later in the life of an installation that the reality of the continuing overhead associated with opening such a flange is realised. The flanged Bandlock™2 Closure offers a quick and easy solution to this problem and, over the lifetime of the pressure vessel, may provide significant cost and time savings to the operator.
