ASME B16.9 10CrMo9-10 Alloy Steel Weld Neck Flange with PN100 Pressure Rating for Industrial Pipe Fittings

The Welding Neck Flange is engineered to meet ASME B16.9 standards, delivering exceptional quality and performance for demanding industrial applications. Manufactured through precise forging and machining processes using high-grade P245GH material, this flange offers outstanding mechanical properties and durability under high pressure and temperature conditions.

Designed for butt weld connections, the Welding Neck Flange provides secure, leak-proof joints that withstand rigorous stresses in critical piping systems. The smooth flow path minimizes turbulence, reducing corrosion and erosion risks within pipelines.

Our product range includes specialized variants such as 10CrMo9-10 EN 1092-1 for excellent creep strength and corrosion resistance at elevated temperatures, 1.4571 (316Ti) Lap Joint Flanges for easy maintenance, and EN 1092-1 PN100 Weld Neck Flanges made from high-strength 42CrMo4 alloy steel for extreme pressure applications.
