Welding Procedure for Super Duplex 2507 Flanges
- Clean flange surfaces free of grease, oil, rust and scale
- Check alignment and the correct gap before welding
- Weld using GTAW or GMAW
- Adjust current, voltage, travel speed and shielding gas flow rate for the right weld bead
The same steps apply to weld neck, SORF and socket weld flanges.
Pressure Rating of RTJ Flanges
- Rating varies with size, class and design standard

Frequently Asked Questions
Super duplex 2507 flanges — Questions Buyers Ask Most
What is a weld neck flange used for?
What is involved in weld neck flange welding?
What are SORF flanges?
Slip-on raised face flanges that slide over the pipe end and are welded. Suited to lower-pressure applications.
How is a socket weld flange different from a weld neck flange?
Socket weld: the pipe slots into a socket. Weld neck: butt-welds directly to the pipe
What pressure classes are available?
150, 300, 600, 900, 1500 and 2500
Flange manufacturers properly clean the flange surfaces to ensure they are devoid of all contaminants including grease, oil, rust and scale. They check and verify if the flanges are accurately aligned and sync together with the provided gap for welding processes.
Super duplex 2507 flanges are typically welded using the gas tungsten arc welding (GTAW) or gas metal arc welding (GMAW) process. Parameters such as current, voltage, travel speed, and shielding gas flow rate are then adjusted to achieve the desired weld bead shape.
2507 slip on flange manufacturer in India
Alloy 2507 blind flange exhibits high tensile strength typically in the range of 750-1000 MPa as compared to other flange types. Thus, this grade flange can better withstand significant mechanical forces and pressures than other flanges.
The yield strength of the 2507 super duplex slip-on flange is typically much higher than the 550 MPa limit. This excellent high yield strength boosts the overall structural integrity of the flange material which is rarely found in other flange types.
