The SAMMI Line blinds are safety devices required to isolate equipment and blind off pipe lines. Positive pipeline Shut-off is vital in many piping systems to assure safety of personnel working on downstream equipment, particularly when flammable or toxic products could leak past a closure. When visible proof of isolation is necessary, a line blind is a mandatory safety device to comply with plant regulations.
The SAMMI line blinds offer a unique non-spreading design which performs the blinding operation without spreading the process pipe. Therefore no stress is put to the process pipe while changing the spectacle plate. No tools are required to perform this operation!
