1. Material: F51
3. Standard: ANSI
4. Pressure: 900#
F51 Blind Flange RTJ has a long tapered hub and are often used for high pressure applications. When ordering a weld neck flange, it is important to specify the schedule pipe is being used for. This is because the inside diameter of the flange will match the inside diameter of your pipe. The buttweld joint this flange has with the pipe along with the tapered hub, makes this flange very resistant to dishing and a very sturdy connection.

Blind Flange
What is a blind flange?
A blind flange also called blank flange,it looks like a plate with bolts holes around.The function of a blind flange is like a pipe cap,but it could be assembly easily by the bolts.There is no inner hole on the blind flange comparing to other type flanges,so the blind flange is used to close the end of a vessel or piping system,and it is not connect with any pipe or vessel.Blind flange also be used for pressure testing for prevent the liquid or air flow..
