Ring Type Joint Flanges (RTJ Flange)

Ring Type Joint (RTJ) Flanges are specially designed to handle high-pressure and high-temperature applications, commonly used where welding is not practical or safe. Their design ensures a strong, leak-proof connection even in harsh or hazardous environments. These flanges are widely used in automotive, petrochemical, and engineering industries due to their reliability and robustness.

RTJ Flanges are available in a variety of materials such as Stainless Steel, Carbon Steel, Duplex & Super Duplex Steel, Alloy Steel, Monel, Inconel, Hastelloy, Copper Nickel, and Alloy 20. This broad range allows for application versatility across industries with varying environmental and mechanical requirements.

These flanges are offered in custom sizes, pressure ratings, and face types to suit project-specific needs. They are ideal for use in pipeline systems, offshore drilling, refineries, and chemical plants where strong sealing and performance under stress are required. Their non-welded installation feature makes them especially suitable for sensitive operations.

RTJ Flanges are exported globally to countries including Qatar, Saudi Arabia, UAE, Indonesia, the United States, Singapore, Malaysia, South Africa, and Australia. Customers value these products for their dimensional accuracy, durability, and high-performance under pressure. Each flange is delivered with proper certifications and documentation.

Ring Type Joint Flanges are manufactured in sizes ranging from 1/2″ (15 NB) to 84″ (2100 NB), making them suitable for a wide range of piping applications. These flanges are designed as per international standards including ANSI B16.5, ANSI B16.47 Series A & B, MSS SP44, ASA, API-605, AWWA, and can also be customized based on specific project drawings.

They are available in pressure classes from 150 LBS to 2500 LBS, as well as DIN standards ranging from ND-6 to ND-40, ensuring compatibility with various pressure systems. RTJ Flanges come in different face types such as Flat Face (FF), Raised Face (RF), and Ring Type Joint (RTJ) to suit diverse sealing requirements.

Conforming to BS and DIN specifications like BS4504, BS1560, BS10, and DIN2527 to DIN2673, these flanges meet global quality benchmarks. All RTJ Flanges are manufactured to comply with NACE MR0175 / ISO 15156 standards, making them ideal for use in sour service and corrosive environments.
