Spectacle blinds - 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.

Differentiation between ANSI and DIN / EN ANSI eyeglass blinds differ from DIN / EN eyeglass blinds in terms of pressure levels, sealing strips and materials. In German-speaking countries, glasses blind disks are also called blind disks or throttle disks. However, the English terms “spectacle blind”, “blind paddle” are also often used in Germany. Pressure ratings according to ANSI in lbs The following pressure levels for blind disks according to ANSI are available 150, 300, 600, 900 and 1500 lbs. Sealing strips The following forms of sealing strips are available: SMF, FF, RF and RTJ. Materials The steel materials A 516 GR 60 and A 516 GR 70 are available. In the stainless steel sector, the materials TP 304 / L, TP 316 / L and TP 312 are possible.
