Blind flanges are often fitted on pressure vessels and pipelines 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. In some cases, companies are not aware that their pipeline access system is contributing to higher operational costs. The cumulative downtime caused by blind flanges can cause inefficiencies, driving up costs.

Celeros Flow Technology brand, GD Engineering, can offer a simple solution – the flanged GD Bandlock2 Closure which can be fitted to new or existing installations as a simple and direct replacement for the blind flange. 

GD Bandlock 2 Closures provide horizontal or vertical access to any pressure vessel in seconds. They can be operated safely at fast speeds. Any size of unit can be opened or closed in less than a minute, with no special tools required.

The tried and tested locking band mechanism which gives the range its name is a duplex stainless steel conical thrust locking band fitted between the closure door and hub. It is designed to transmit the pressure load uniformly around the full 360° circumference of the hub.
