Spades - Import export

A spectacle blind consists of a spade and a spacer which are manufactured for the purpose of installation in one piece. It is used as a safety device to isolate a particular section of pipe or equipment when this section or this equipment is to be inspected or decommissioned. It is different from a valve in the sense that the obturator is considered an isolation device. Depending on the size and class of flanges, it will be more suitable to offer two separate components (spade and spacer) instead of a spectacle blind to limit weight and avoid handling heavy parts.
