RTJ Flanges

RTJ Flanges

Vandan Alloys is a manufacturer, supplier, stockist and exporter of RTJ Flanges (Ring Type Joint Flanges) for high-pressure and critical piping applications. RTJ flanges use a precision-machined ring groove and a metallic ring gasket to provide a reliable pressure-tight joint when assembled correctly according to the applicable flange and piping requirements.

RTJ facing can be supplied on applicable flange configurations such as Weld Neck, Blind and other suitable flange types, depending on the standard, size, pressure class and project specification.

RTJ Flange Design

RTJ Flanges incorporate a machined annular groove that receives a metallic ring gasket. During bolting, the ring gasket is seated within the groove to create the sealing arrangement.

The RTJ groove, flange dimensions, ring-gasket selection and bolt-up procedure must be compatible with the applicable standard and service conditions. Proper assembly is essential to achieve the intended sealing performance.

RTJ Ring Gasket Compatibility

RTJ flange assemblies are used with metallic ring-type joint gaskets selected according to the applicable groove configuration, pressure class, material and service requirements.

The ring gasket designation and dimensions should be verified against the applicable flange standard and project specification before ordering.

Pressure Classes

RTJ Flanges are commonly supplied for Class 300, 600, 900, 1500 and 2500 applications where the applicable standard permits RTJ facing.

Class 150 RTJ availability and configuration are dependent on the applicable standard, size and design specification and should be confirmed for the required application.

Pressure-class selection should consider design pressure, design temperature, material grade and the applicable piping code.
