10CrMo9-10 Alloy Steel Weld Neck Flange EN 1092-1 Standard PN100 Pressure Rating

The Welding Neck Flange is a critical component designed for high-pressure and high-temperature piping systems, providing reliable leak-proof connections between pipes, valves, and equipment. Manufactured using advanced forging techniques, this flange ensures superior strength, durability, and performance under demanding industrial conditions.

This particular Welding Neck Flange is constructed from high-quality Carbon Steel (steel number 1.8845), corresponding to X10CrMoVNb9-1 (F91) alloy. This material offers excellent mechanical properties with exceptional resistance to creep and oxidation at elevated temperatures, making it ideal for power generation, petrochemical, and heavy industrial applications.

The flange complies with EN 1092-1 standards, ensuring precise dimensions, tolerances, and performance criteria that meet international requirements. It features WELD-END PREPARATION FOR FLANGES TYPE 35, which optimizes the welding process by providing an engineered bevel for strong, consistent weld joints.

The Welding Neck Flange is essential in piping systems requiring high strength and durability. Its primary applications include:

• Heavy-duty industrial pipelines requiring leak-proof joints
• Oil and gas industry applications
• Petrochemical plants and power generation facilities
• Chemical processing and marine environments
• High-pressure and high-temperature systems

The long tapered hub design allows butt-welding to pipes, providing smooth transitions that reduce stress concentration and enhance fatigue resistance.
