Ring-Type Joint Blind Flanges

Capping off a pipe in a high-pressure or high-temperature piping system requires a stronger, more durable seal. A ring-type joint blind flange is ideal for isolating sections of pipe, capping off unused branches, or performing maintenance and repairs on the piping system.

For top-quality RTJ blind flanges that you can count on for a reliable seal in extreme conditions, turn to our team at Hydro Blind Solutions. We feature RTJ blind flange purchases and rentals and ship throughout the U.S. and globally.

Our company offers 24/7 service so we can take your order anytime, and we ship fast so you can avoid project delays. We’re here to help with all your isolation piping needs, and we manufacture all our industrial piping products in-house for the highest-quality results.

What Is an RTJ Blind Flange?

A standard flat-faced blind flange is a circular plate of steel with a series of holes drilled around the perimeter to allow it to be bolted to a pipe flange. A flat gasket is placed between the blind flange and the pipe flange to create a seal.

A raised-face blind flange features a raised center section inside the bolt holes on one side of the plate. This allows the blind flange to accept a variety of full-face and raised-face gaskets to provide a better seal in high-pressure situations.

A ring-type joint blind flange looks similar to a raised-face blind flange, but just inside the edge of the raised face is a circular machined groove. This groove accepts metal gaskets with an oval or octagonal cross-section, similar to an O-ring.

When the RTJ blind flange is bolted to a pipe flange, the metal gasket is deformed, creating a tight, leak-free seal for high-pressure, high-temperature, or highly corrosive applications.
