Solid PTFE sliding spectacle blinds for acid lines

A more permanent form of blanking spade, sliding blinds combine the functions of blanking spades with ring spacers. They’re installed into the pipeline as a water fitting and require the flange bolting to be loosened so it can be slid into its closed or open position. Produced from solid PTFE, they allow unhindered flow through the pipeline in their open state, but when closed positively and effectively seal the pipeline, preventing any flow and protecting plant and personnel. In comparison to blanking spades, they have the advantage of being quite clear as to whether the blind is open or closed. The slotted holes fit the bolting and align the blind within the flange joint.
