Weld Neck Flange Type 11/B1 EN1092-1 PN16

TECHNICAL DESCRIPTION

Neck (skirt) flanges according to standard EN1092-1 / type 11 / B1 are pipeline elements with a wide size range, which are widely used in the construction of steel pipelines and pipe segments (spools) used in industry, industry and ship repair.

We stock EN1092-1 type 11 / B1 sealing surface steel flanges, but we also have the necessary machining equipment, which allows us to offer flanges with sealing surfaces.

• sealing surface type A, B2, C, D, E, F
• non-standard sealing surfaces on request
• profile grooves for metal sealing rings (segments) type RTJ
• flanges made on request by the customer, and others.

SUPPORTED MATERIALS IN STOCK:

• Carbon steel

P250GH (1.0460) / EN 10222-2

Dimensions: DN 10 – 2000

Description

The Weld Neck Flange Type 11/B1, manufactured in compliance with EN1092-1 standard and rated for PN16 pressure, is engineered for high-performance industrial piping systems. Its robust design ensures a secure, leak-proof connection in demanding environments, making it ideal for applications in oil and gas, chemical processing, and power generation. The weld neck configuration provides superior stress distribution, reducing the risk of fatigue and enhancing system longevity under high-pressure and temperature conditions.Key features of this flange include:Material Grade: Type 11/B1, ensuring excellent mechanical properties and corrosion resistancePressure Rating: PN16, suitable for systems operating up to 16 barStandard Compliance: EN1092-1, guaranteeing interoperability and safety in European and international marketsWeld Neck Design: Facilitates smooth flow transition and minimizes turbulenceThis product is essential for engineers and procurement specialists seeking reliable, standards-compliant flanges that meet rigorous operational demands. Its certification under EN1092-1 ensures quality assurance, while the PN16 rating offers versatility across various industrial sectors. Optimize your piping infrastructure with this durable, high-integrity component designed for seamless integration and long-term reliability.
