Case Study - Installation of Blind
A contractor working on a chemical plant in Freeport, Texas, contacted Equalizer Americas for a solution to the problems they were facing with a misaligned flange.
Maintenance work was scheduled on 18" 600# pipework where the flanges were to be spread and a 2¾” wide blind was to be set in order to test the line. When the contractor began to de-torque and remove the bolts the day before maintenance was scheduled, the flange quickly began to misalign and the remaining bolts bound and seized in the boltholes.
