Quick Acting Pipeline Blinds

The SAMMI Pipeline Blind achieves Zero Leakage.
The innovative yet simple open-close mechanism of our Pipeline Blinds means that one person can easily, quickly and safely isolate piping – up to 100″ (DN2500).
Swinging Blinds can typically take many hours and may require a crane or other lifting device. Calculating the cost of swinging blinds must also include lost production time and this is where Sammi Pipeline Blinds outperform the competition and show their true worth.
