Ferrobend manufactures and supplies premium quality Ring Type Joint Slip-On Flanges (RTJ) designed for reliable, leak-resistant connections in demanding industrial piping systems. Featuring a slip-on design and precision-machined Ring Type Joint (RTJ) groove, these RTJ Slip-On Flanges provide dependable metal-to-metal sealing, accurate installation, and secure bolted connections. Suitable for oil & gas, refinery, petrochemical, chemical processing, and power generation applications where reliable sealing is required.
A Ring Type Joint Slip-On Flange (RTJ SO Flange) is a forged flange designed to combine the installation convenience of a Slip-On Flange with the reliable sealing capability of a Ring Type Joint (RTJ) gasket. The flange slips over the pipe and is secured by fillet welds on the inside and outside, providing a strong and permanent connection.
The precision-machined RTJ groove accommodates a metallic ring gasket, which is compressed under bolt load to create a high-integrity metallic seal. This makes RTJ Slip-On Flanges suitable for applications requiring dependable sealing performance under demanding pressure and temperature conditions.
With their compact design and easier installation, RTJ SO Flanges can be a practical choice where installation convenience, alignment, and reliable sealing are important. They are used in oil & gas, petrochemical, refinery, power generation, and industrial piping systems.
The flange slips over the pipe, allowing easier positioning and alignment before welding compared with butt-weld flange configurations.
A precision-machined RTJ groove and metallic ring gasket provide a high-integrity seal suitable for demanding pressure and temperature conditions.
Inside and outside fillet welds provide a secure and permanent connection between the flange and pipe when properly designed and welded.
Unlike Weld Neck Flanges, Slip-On Flanges generally do not require the same beveled pipe-end preparation, simplifying certain installation requirements.
RTJ Slip-On Flanges can provide reliable performance under vibration, thermal cycling, and pressure fluctuations and are used in oil & gas, petrochemical, refinery, power generation, and industrial piping systems.
Ring Type Joint Slip-On Flanges (RTJ SO Flanges) combine the installation convenience of a Slip-On Flange with the reliable sealing performance of a metallic RTJ gasket. Their compact design and dual fillet-weld connection make them a practical choice for piping systems where installation efficiency, mechanical strength, and sealing reliability are important.
The Ring Type Joint Slip-On Flange (RTJ SO Flange) is designed to combine installation convenience, mechanical strength, and reliable metallic sealing. Its straight bore allows the flange to fit over the pipe, while the precision-machined RTJ groove provides accurate seating for the metallic ring gasket.
Key Design Features
When the flange bolts are tightened, the metallic RTJ gasket is compressed within the groove to form a high-integrity metallic seal suitable for demanding pressure and temperature conditions.
RTJ Groove & Ring Types
RTJ Slip-On Flanges can be manufactured to accommodate applicable metallic ring gasket designs, including:
The correct RTJ groove, gasket profile, pressure class, material, and applicable standard should be selected together to ensure proper gasket seating and sealing performance.
Ring Type Joint Slip-On Flanges (RTJ SO Flanges) offer a practical combination of installation flexibility, mechanical strength, and reliable metallic sealing. Their slip-on design simplifies flange positioning, while the RTJ groove and metallic ring gasket provide dependable sealing for demanding industrial piping applications.
The slip-on design allows the flange to fit over the pipe, making positioning and alignment easier during installation and reducing the need for extensive pipe-end preparation.
The precision-machined RTJ groove and metallic ring gasket create a high-integrity sealing system suitable for demanding pressure and temperature conditions.
Internal and external fillet welds provide a strong and permanent pipe-to-flange attachment when properly designed and executed.
The robust RTJ sealing system can perform reliably under vibration, thermal cycling, and pressure fluctuations, making it suitable for demanding service environments.
RTJ Slip-On Flanges are available in various carbon steel, stainless steel, alloy steel, and duplex materials, making them suitable for oil & gas, petrochemical, refinery, power generation, and industrial piping systems.

Shaped by heating a solid billet and compressing it under high pressure, aligning the grain flow for superior strength and pressure resistance.
Billet progressively shaped by rotating rollers, giving a uniform grain structure and high fatigue resistance.
Machined directly from a flat metal plate without forging — a cost-effective option for low-pressure or non-critical applications.
Our products are tested and certified as per international quality standards with complete traceability and documentation.
