ASME EN DN900 PN10-100 Stainless Steel Plate Flange
Production Standard：ASME B16.5, ASME B16.47, EN 1092-1 Type 01, DIN 2573~2576, ISO 7005-1, JIS B2220, GOST 12820-80, API 6A, AS/NZS 4087, GB/T 9124.1-2019.
The Robust Joint of the Industrial Skeleton: Analyzing the Core Functions of Weld Neck Flanges
Function: The core function of a Weld Neck Flange is to serve as a permanent, non-detachable connection point in high-pressure, high-temperature, or critical piping systems. Through its unique tapered hub, it is butt-welded to the pipe, forming a continuum with strength equivalent to the pipe itself. Its primary role is to safely convey fluid and withstand internal pressure, thrust, and other mechanical loads within the system.
Advantages:
Exceptional Strength: The butt weld is the strongest type of pipe connection, with weld strength equal to the pipe base metal.
Perfect Stress Distribution: The tapered hub creates a smooth transition from the flange thickness to the pipe wall thickness, significantly reducing stress concentration and preventing fatigue failure.
Excellent Sealing: The robust structure and precisely machined sealing faces (e.g., RF, RTJ) ensure zero leakage, even under extreme conditions.
Practical Application Scenario: Main steam lines in power plants. These pipelines carry superheated, high-pressure steam. Failure of any connection could lead to catastrophic events. Weld Neck Flanges are mandatory here because they reliably withstand immense pressure and temperature fluctuations, ensuring the power plant's safe operation.
