Weld Neck Flange EN 1092-1

At UTMK, you can order certified Weld Neck Flanges (WN) engineered for critical high-pressure and high-temperature applications. We guarantee a stable supply of fully compliant products, ensuring the integrity and safety of your demanding industrial piping systems according to EN 1092-1 Type 11 standards.

Technical Characteristics

The weld neck flanges in our product range are manufactured in strict accordance with European standards, featuring specifications designed to meet the most challenging engineering requirements.

Advantages of Weld Neck Flanges

The design of a weld neck flange provides several key benefits that make it the superior choice for critical and high-stress piping systems.

• Superior Joint Integrity and Safety. The tapered hub design effectively transfers stress from the flange to the pipe, minimizing concentration at the base. This significantly reduces the risk of fatigue failure in systems with high pressure, temperature fluctuations, and vibration
• Ideal for Critical High-Load Applications. The butt-weld connection provides a strength comparable to that of the pipe itself, making these flanges the standard for main pipelines, power generation, and high-pressure processing systems
• Optimized Flow Dynamics. The smooth, continuous transition from flange to pipe eliminates turbulence and pressure drops at the connection point. This enhances overall system efficiency and reduces the potential for internal erosion over time
• Wide Range of Operating Conditions. Manufactured from materials like S235JR and other alloy steels, these flanges are suitable for extreme temperatures ranging from cryogenic levels (-253°C) up to +600°C, ensuring reliability in diverse environments

Areas of Application

Due to their inherent strength and reliability, EN 1092-1 Type 11 flanges are the standard for industries with demanding operational conditions and strict safety requirements.

• Oil and Gas. Upstream and downstream processing, transmission pipelines, and offshore platforms where high-pressure containment is critical, often in line with API specifications
• Power Generation. High-pressure steam lines in nuclear and conventional power plants, where reliability under extreme thermal cycling is paramount
• Chemical and Petrochemical Processing. Connecting reactors, vessels, and piping for aggressive media, where joint integrity prevents hazardous leaks
• Shipbuilding and Marine. High-pressure hydraulic systems, engine room piping, and structural connections requiring robust and certified components.
• Water Treatment and Distribution. Main distribution networks and high-pressure pumping stations
