Flange Bending
Ankay Büküm produces flange rings by bending flat steel bars into circular forms for pipe connections.
What Is Flange Bending?
Flange bending is the process of forming flat rectangular steel bars (flat bars) into circular shapes to create flange rings used at pipe connections, joint locations, and assembly points. These ring-form components are essential elements for penstock segment connection flanges, tank rim frames, and industrial pipeline systems. At Ankay Büküm in Ankara's Ostim Industrial District, we provide precision flange bending services in thicknesses from 5 mm to 100 mm, serving as a reliable partner particularly in hydropower penstock projects and heavy industrial fabrication.
Application Areas
- Penstock Connections: Bolted connection flanges for joining penstock pipe segments, diameters from DN300 to DN3000
- Industrial Pipelines: Connection flange rings for process lines, steam lines, and water transmission pipelines
- Tank and Vessel Fabrication: Storage tank rim flanges, manhole frames, and connection point rings
- Pressure Vessel Manufacturing: Cover flanges, nozzle connection rings, and inspection window frames
- Steel Structures: Steel column base flanges, pipe column top connection rings, and structural connections
Technical Capacity and Specifications
Our facility bends flat bars from 5 mm to 100 mm thick and 20 mm to 400 mm wide into flange rings. Flange diameters from DN200 to DN5000 and beyond are achievable. Post-bending services include end-to-end welding, hole drilling, and surface finishing. Processing capacity covers S235JR, S355J2, 16Mo3, and stainless steel materials.
Quality Assurance
Flange dimensional accuracy is critical for preventing pipeline leaks. Every flange undergoes template checking, flatness measurement, and diameter verification after bending. Connection holes are drilled on CNC machines for precision tolerances. Production complies with EN 1092 and ASME B16.5 flange standards.
Ankay Büküm provides a strong service network from Ankara Ostim to all of Turkey for flange bending. For flange ring production at every scale, from penstock projects to industrial pipelines, consult our technical team. With over 30 years of experience, we bring quality and reliability to your projects.
