GENERAL INFORMATION INSTRUCTION & FEATURES

EX type Line blind offers 100% pipe isolation for hazardous service conditions such as extremely high temperature, cryogenic, gas/liquid contained particles and/or polymer production pipeline. The unique stretching mechanism creates a gap to switch blind plate positions quickly and efficiently.
