The Ring Type Joint (RTJ) flange face style is a highly durable and precise sealing solution commonly used in pipe fittings. It features a recessed groove that accommodates a metallic ring, typically made of materials such as stainless steel, that creates a tight, leak-proof seal when compressed between two flanges. RTJ flanges are primarily used in high-pressure and high-temperature applications, offering superior sealing capabilities and resistance to extreme conditions. This flange face style is widely utilized across various industries, including oil and gas, chemical processing, and power generation, and is available in multiple classes and material types to meet diverse application requirements.
