ANSI B16.5, ASME B16.47 Ring Type Joint Flange Manufacturers

ASME B16.47 RTJ Flanges Manufacturers and Suppliers:

Ring Type Joint Flanges, also known as RTJ flanges, are a type of flange designed for high-pressure and high-temperature applications. They are commonly used in the oil and gas industry, as well as in chemical and petrochemical plants.

RTJ Flanges have a raised ring or groove in their face that serves as a seal, which is compressed against the mating flange to prevent leakage. The sealing material is usually a soft iron, stainless steel, or other metallic material that is selected based on the application’s temperature, pressure, and chemical compatibility.

ADCO Forge and Fittings is a most reputed manufacturer and supplier of high-quality Ring Type Joint Flanges (RTJ Flanges) for various industries, including oil and gas, petrochemical, and power generation. With years of experience, developed a reputation for producing reliable and durable flanges that meet or exceed industry standards. offer a wide range of RTJ flange sizes, ratings, and materials to meet the diverse needs of customers. We committed to providing excellent customer service, timely delivery, and competitive pricing to ensure customer satisfaction.

To ensure proper installation of RTJ flanges, it is important to use the correct torque values for the bolts. A torque chart is typically provided by the manufacturer, which indicates the recommended torque values for the specific size and rating of the flange. It is important to follow the torque chart closely to ensure that the flange is properly sealed and prevent leaks.

The dimensions of RTJ flanges are standardized according to various industry standards, including ASME B16.5 and API 6A. These standards specify the dimensions, tolerances, and materials for the flanges, ensuring that they are compatible and interchangeable between different manufacturers and suppliers. It is important to select the appropriate size and rating of the flange based on the application’s requirements to ensure safe and reliable operation.
