Product Description

Spectacle Blind

  • A spectacle blind is a safety device used to isolate a section of line.
  • It is a piece of equipment used when the line or equipment needs to be inspected or removed from service.
  • It is different than a valve in that the blind is a permanent or long term isolation device.
  • WHAT IS THE FORMULA TO CALCULATE THE THICKNESS OF A SPACER?

    Sometimes it is necessary to use a thinner spacer, because a spacer with a standard thickness often can not be mounted between two flanges...Think of a pressure test in a "Life Plant" where a spacer should be installed between two flanges.

    As a rule of thumb the following formula can be used to calculate the thickness in millimeters:

  • Pressure (barg) multiply by diameter (inches) divided by 10
  • Pressure: the highest pressure that the system can achieve
  • Diameter: the size of the spacer in inches
  • Example: 8 x 12 / 10 - thickness of spacer = 9.6 mm
  • NOTE: always try to apply spacer thicknesses in accordance with ASME B16.5
