Bifurcation Segment

Ankay Büküm manufactures T/Y junction bifurcation segments for main-to-branch penstock pipe transitions.

What Is a Bifurcation Segment?

A bifurcation segment is a specialized T-shaped or Y-shaped junction piece that provides transition from the main penstock pipe to one or more branch lines. In HPP projects, it is typically used at points where a single penstock line distributes water to two or more turbines. It is the most complex penstock component from an engineering perspective, requiring integrated hydraulic, structural, and welding calculations. At Ankay Büküm in Ankara's Ostim Industrial District, we manufacture bifurcation segments from DN300 to DN3000, supplying critical components for multi-turbine HPP projects.

Application Areas

HPP Turbine Distribution Points: Junction points where the main penstock splits to two or three turbines, Y and T-shaped pieces
Water Distribution Systems: Transition points from main transmission lines to multiple distribution lines
Industrial Pipelines: Branch line transition pieces from process main lines
Cooling Water Systems: Distribution from power plant cooling water main line to distribution branches
Pressure Balancing: Pressure balancing and surge tank connection points on penstock lines

Technical Capacity and Specifications

Our bifurcation segment production covers main pipe DN500 to DN3000 and branch pipe DN300 to DN2000. T-type (90-degree) and Y-type (30-60 degree) configurations are produced. Body wall thickness 8-60 mm, junction zone reinforcement plates 12-80 mm thick. Manufacturing integrates specialized plate development calculation, CNC cutting, bending, welding, and machining. All weld seams are full penetration.

Quality Assurance

Bifurcation segments experience the highest stress concentration in penstock systems, demanding the strictest quality control. All weld seams undergo 100% RT and UT inspection. The junction zone is manufactured per design verified by finite element analysis (FEA). Hydrostatic testing at 1.5x design pressure is performed when required. Full compliance with EN ISO 3834-2, EN 10219, and AWWA M11 standards is maintained.

Ankay Büküm offers integrated engineering design, manufacturing, and quality control for bifurcation segments. Contact our expert team in Ankara Ostim for bifurcation segment needs at turbine distribution points of your HPP projects. Let us develop the optimal bifurcation design supported by hydraulic calculations and structural analysis together.

Frequently Asked Questions

What is a bifurcation segment and what is it used for?

A bifurcation is a T or Y-shaped junction piece providing transition from main pipe to branch line in penstock systems. Used at HPP points where the main line splits to multiple turbines.

What sizes are bifurcation segments produced in?

Main pipe DN500-DN3000, branch pipe DN300-DN2000. Body 8-60 mm, reinforcement 12-80 mm. T-type (90 degrees) and Y-type (30-60 degrees) produced.

What is Ankay Büküm's bifurcation capacity?

T and Y-type bifurcation segments with main diameter up to DN3000 and branch up to DN2000. 100% RT+UT inspection and hydrostatic testing applied.

What is the difference between T-type and Y-type?

T-type branches at 90 degrees. Y-type branches at 30-60 degrees and is hydraulically more efficient. Selection depends on hydraulic calculations and layout conditions.

How are pricing and delivery times determined?

Pricing based on main and branch diameters, thickness, configuration, material, and NDT scope. Manufacturing time 4-10 weeks depending on complexity. Contact us for project calculations.
