Overview

RTJ Flanges (Ring Type Joint Flanges) are specially designed flanges that use a metallic ring gasket seated inside a precision-machined groove to create a strong and reliable seal. These flanges are widely used in high-pressure and high-temperature environments where standard gasket sealing may not be suitable.

Manufactured with advanced engineering processes and high-grade raw materials, RTJ Flanges offer excellent mechanical strength, dimensional accuracy, and resistance against extreme operating conditions. Their metal-to-metal sealing design ensures maximum reliability and safety in critical applications.

Veltronova Industries supplies premium quality RTJ Flanges in various materials, pressure ratings, sizes, and international standards. Our RTJ Flanges are widely used in oil & gas pipelines, petrochemical plants, refineries, chemical processing units, power generation plants, offshore applications, and heavy engineering industries.
