The term "paddle blind" is generic term and does not imply thickness or purpose of the blind (isolation or testing).

A "hydroblind", also often referred to as a "spec blind" or "hydrotest blind", is designed to handle the maximum pressure a pipe would be subjected to for testing purposes per ASME specifications.

Depending on the company, some use only hydroblinds for isolation Or testing as they consider this a safer way to operate. This way they know it will hold up if latent pressure builds up in the line. The hydroblind will not fail in this situation, where a thin isolation blind could if the pressure raises high enough.

This is dependent on the flange's AMSE rating. Sizes and thickness are manufactured to the ASME 16.48, API 590, ASME 16.5 specifications and will hold the pressure that the spec calls for.

Some other names we've heard a paddle blind referred to are: skillet blind, pancake blind, slip blind, test blind, hydroblind, hydrotest blind, spec blind, isolation blind, blank, and stop blind.

Did we miss one? Let us know and we'll add it to the list!

Of course! We regularly manufacture blinds out of more than 20 different materials, and we can make them out of practically any material at your request.

We use the handle colors as a quick way of identifying the flange rating for our blinds from a distance.
