Stainless Steel Weld Neck Flanges Manufacturer, Suppliers, Stockist, Exporters
A Weld Neck Flange is composed of round components with an extended border around its perimeter. Typically machined from metal, these flanges are often joined to a tube by butt welding. Around its edge, the flange has several drilled holes that allow it to be connected to another flange. Every diameter, every standard face type (flat, raised, RTJ), and all types of Weld Neck Flanges are available and manufactured.
Furthermore, these Stainless Steel Flanges also offer optimum stress distribution due to their pressure-gradient hub and can be radiographed to detect any flaws. They possess a high level of integrity and are ideal for scenarios requiring higher temperatures and pressures due to the strength of the hub and the quality of the weld.
Various Materials In Which Of Weld-Neck-Flanges Are Available
Flanges are made up of various materials, but they depend on the environment and stress to which they are subjected.
- Carbon steel
- Alloy Steel
- Stainless steel
- Titanium
- Duplex & Super Duplex Steel
- Nickel alloy
When temperatures and pressures are moderate, carbon steel flanges are typically used. When extreme conditions are present, alloy steel flanges are typically used. Last but not least, alloys containing metals such as nickel, chromium, or molybdenum are ideal for corrosive gases and liquids.
Features of Weld-Neck-Flange
- Weld Neck Flanges are used in piping systems for joining pipes to other equipment or components.
- They have a long tapered hub that helps in the smooth transition of the pipe to the flange.
- The neck of the flange provides reinforcement and reduces stress concentration at the joint.
- Weld Neck Flanges have higher strength compared to slip-on or threaded flanges.
- They are ideal for high-pressure and high-temperature applications.
- The welding neck design ensures a strong and leak-proof connection.
- They are available in various sizes and pressure ratings to suit different requirements.
- Weld Neck Flanges are commonly used in industries such as oil and gas, petrochemical, and power generation.
- They are compatible with different welding methods, including butt welding and socket welding.
- The raised face on the flange helps in providing a sealing surface when the flange is bolted to another flange or equipment.

Benefits of Weld Neck Flanges
- A flange of this type can withstand pressures up to 5,000 pounds per square inch.
- There is excellent stress distribution along the hub’s taper.
- There is no restriction on flow across the valve and a low-pressure drop across it (low delta P).
- They have Exceptional cyclical load capability.
- There is minimal turbulence caused by this aircraft.
- Erosive conditions are low.
- It is more expensive to use weld neck flanges due to their design, engineering, and increased material requirements.
- With larger diameter flanges, you can perform non-destructive testing on the weld.
