Welding Neck Flanges 13CrMo4-5 1.7335 EN 1092-1 Type 11 PN25 Steel Number 1.4550 PN25 Flanges for High Temperature Service
Product Overview
The Welding Neck Flange is a critical component widely used in various piping systems for its superior strength, durability, and reliable performance. Manufactured in China, this flange type provides secure and leak-proof connections between pipes, valves, pumps, and other equipment.
Constructed from high-quality forged material F51, these flanges offer exceptional toughness and corrosion resistance, making them suitable for harsh environments and aggressive media. F51 is a duplex stainless steel grade that combines the benefits of both austenitic and ferritic stainless steels, resulting in enhanced strength and resistance to stress corrosion cracking.
Available with Raised Face (RF) and Flat Face (FF) options, these flanges provide flexibility for specific connection requirements and gasket types.
