Weld Neck Flange Type 11/B1 EN1092-1 PN6

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, compliant with EN1092-1 PN6, is engineered for high-performance industrial piping systems requiring robust and leak-proof connections. Its design features a tapered hub that provides structural reinforcement, making it ideal for high-pressure and high-temperature applications across sectors such as oil and gas, chemical processing, and power generation. Manufactured to exacting European standards, this flange ensures compatibility and reliability in critical infrastructure projects.Key specifications and benefits include:Material Grade: Type 11/B1, suitable for various steel compositionsPressure Rating: PN6, designed for nominal pressure applicationsStandards Compliance: EN1092-1, guaranteeing interoperability and safetyApplication: Ideal for welding to pipes, offering superior stress distributionDurability: Resistant to deformation under thermal and mechanical loadsThis flange is essential for systems where integrity and longevity are paramount. Its weld neck design minimizes turbulence and erosion, enhancing flow efficiency and reducing maintenance needs. Available in multiple sizes, it supports custom configurations to meet specific project requirements, ensuring optimal performance in demanding environments.
