Top Supplier of Ring Type Joint Flanges, ANSI B16.5 / ASME B16.47 RTJ Dimensions & Pressure Ratings, PN10 / PN16 RTJ Flanges – EN 1092-1 Compatible Ring Type Joint Design, ANSI B16.47 Series A & B RTJ Flanges.
An RTJ (Ring Type Joint) flange is a specialized flange designed to provide a reliable, leak-proof seal in high-pressure and high-temperature applications. The “Ring Type Joint” refers to the metal ring gasket that fits into a groove in the flange, ensuring a secure seal between two pieces of equipment or piping. RTJ flanges are commonly used in industries like oil and gas, petrochemical, power generation, and chemical processing. Available in a range of sizes (from DN 15 or ½ inch up to DN 1200 or 48 inches), these flanges are typically made from carbon steel, stainless steel, and alloy steel, chosen for their durability and resistance to harsh environments. RTJ flanges can be designed with a flat face or raised face, depending on the application, with the flat face type being commonly used when connecting to flanges with a matching flat surface for a tighter seal.
RTJ flanges are classified by pressure classes such as 150, 300, 600, 900, 1500, and 2500, indicating their pressure tolerance. These flanges adhere to standards like ASME B16.5, ASME B16.47, and API 6A, ensuring that they meet industry specifications for design, material strength, and dimensions. The application of RTJ flanges spans across industries with high-pressure systems, including oil and gas pipelines, petrochemical reactors, and power generation plants. Their ability to withstand extreme pressure and temperature makes them ideal for critical applications where leaks must be prevented at all costs.
The primary advantages of RTJ flanges include their superior sealing capability, high-pressure resistance, and corrosion resistance. The metal ring gasket in an RTJ flange ensures a tight seal, even under the most demanding conditions. They also offer easy installation and maintenance, as they can be disassembled and reassembled without compromising the integrity of the seal. RTJ flanges are a trusted solution for industries requiring secure, durable, and reliable flanges for high-performance applications.
