Ring Joint Flange Stockist

A ring joint flange (RJ flange) is a type of pipe flange used in high-pressure and high-temperature applications, particularly in industries such as oil and gas, petrochemical, and power generation. This specialized flange design provides a robust and reliable sealing solution for connecting pipes and equipment in demanding environments.

Key features of ring joint flanges:

  1. Design: Ring joint flanges have a distinctive design with a raised ring-shaped gasket groove on the flange face. This groove accommodates a metal ring gasket, which is compressed between the flange faces during assembly to create a tight and durable seal.
  2. Materials: Ring joint flanges are typically made from forged materials like carbon steel, stainless steel, or alloy steel. The choice of material depends on the specific application and the required corrosion resistance and strength.
  3. Pressure and Temperature Rating: Stainless Steel Ring joint flanges are known for their high-pressure and high-temperature capabilities. They are suitable for applications where conventional gaskets may fail due to extreme conditions.

Key features of ring joint flanges:

  1. Design: Ring joint flanges have a distinctive design with a raised ring-shaped gasket groove on the flange face. This groove accommodates a metal ring gasket, which is compressed between the flange faces during assembly to create a tight and durable seal.
  2. Materials: Ring joint flanges are typically made from forged materials like carbon steel, stainless steel, or alloy steel. The choice of material depends on the specific application and the required corrosion resistance and strength.
  3. Pressure and Temperature Rating: Stainless Steel Ring joint flanges are known for their high-pressure and high-temperature capabilities. They are suitable for applications where conventional gaskets may fail due to extreme conditions.
  4. Types: Ring joint flanges come in several different styles, including raised face (RF), flat face (FF), and ring type joint (RTJ). The selection of the flange type depends on the sealing requirements and the system’s design.
  5. Gasket Material: The gasket used in ring joint flanges is typically made from materials like soft iron, low carbon steel, stainless steel, or various alloys. These gaskets are carefully selected to match the operating conditions and ensure an effective seal.
  6. Sealing Mechanism: The metal ring gasket used in ring joint flanges relies on a combination of radial and axial compression to create a leak-tight seal. When the flanges are bolted together, the gasket is squeezed between the flange faces, ensuring a secure connection.
  7. Installation: Proper installation of Carbon Steel Ring Joint Flanges is critical to achieving a reliable seal. The flanges must be aligned accurately, and the bolts tightened according to the specified torque values to ensure uniform compression of the gasket.
  8. Common Applications: SS Ring joint flanges are commonly used in pipelines, wellhead assemblies, pressure vessels, and other equipment where high pressures, extreme temperatures, and corrosive fluids are involved. Their robust design makes them suitable for critical applications in the oil and gas industry, chemical plants, and power generation facilities.
  9. Standards: Ring joint flanges are manufactured in accordance with industry standards such as ASME B16.5 RTJ Flanges and API 6A. These standards specify the dimensions, materials, and pressure-temperature ratings for ring joint flanges.
