Advantages of Type 11 Weld Neck Flange
High strength and pressure resistance
The Type 11 weld neck flange, with its long neck and tapered pipe end, is designed to withstand extreme pressure and temperature conditions, providing robust mechanical strength and stability.
Reduced stress concentration
The long neck design of the type 11 flange effectively disperses stress throughout the pipe, minimizing stress concentration at the flange base and reducing the risk of fatigue failure due to pressure and temperature fluctuations.
Exceptional sealing performance
The smooth welding transition of the weld flange minimizes turbulence and erosion in fluid flow, significantly enhancing overall sealing performance and preventing leakage issues.
Versatile material selection and pressure adaptability
The flange offers flexibility in material choice, including carbon steel, stainless steel, alloy steel, and others, catering to diverse working conditions and accommodating pressure levels ranging from PN 2.5 to PN 400.

FAQ
The main differences between EN 1092-1 Type 11 and B16.5 weld neck flanges lie in their standard specifications, dimensional requirements, pressure ratings, and regional usage. EN 1092-1 is tailored to European standards, while ASME B16.5 is aligned with American standards. When selecting flanges, it’s crucial to consider these differences to ensure compatibility with your piping system’s requirements and regional standards.
Type 11 flanges should be installed by welding the neck to the pipe. Proper alignment and welding procedures should be followed to ensure a strong and leak-proof connection. It is also important to follow any additional guidelines provided by the flange manufacturer or relevant standards.
EN 1092-1 is a European standard that specifies the requirements for flanges used in piping systems. It covers various aspects related to the design, dimensions, materials, and pressure ratings of flanges.
Summary
The Type 11 butt-weld flange provided by SSM has become a key component in various industrial piping systems due to its high quality and reliability, ensuring the system’s safe operation and long-term stability.
