Hamer Blinds

(OP)
Has anyone had a positive experience with hamer blinds in organic service?

I also need to know if you are in an area that would regularly measure the flange of the hamer blind for VOC leaks.

I need to give our operators a safe alternative to our current setup of blinding the furnaces in our ethylene plant.

My company currently only has three applications:
  1.  Crude C4 rail car loading service (no problems with leaks) at 80 PSIG
  2.  Decoke air on a furnace (leaks like a sieve -- no PMs)
  3.  Flare header blinds at 2 PSIG

Any information would be greatly appreciated.

Thanks,BCJ


RE: Hamer Blinds

I had a similar dilema with isolationg crude oil furnaces having common charge lines.

I never did find a good solution using a single device.  Double block and bleed arrangemens (w/blinds) was left on the table for consideration.
