KDT INDUSTRY provides high-performance HP – LP crossover piping systems specifically engineered for seamless integration between high-pressure (HP) and low-pressure (LP) turbine components. These specialized crossover pipes are essential for directing high-temperature steam between turbine stages in thermal power plants, ensuring efficient steam flow while managing thermal expansion and mechanical loads.

What is HP – LP Crossover Piping?

HP – LP crossover piping is a critical part of steam turbine piping systems, allowing the controlled transfer of steam from intermediate or high-pressure turbine sections to low-pressure turbine elements. These pipes are typically large in diameter and exposed to extreme pressure and temperature conditions, requiring robust design, precise fabrication, and reliable expansion mechanisms to maintain operational integrity and performance.

Design Features of Our HP – LP Crossover Piping

• Pressure-balanced construction to reduce stress on turbine casings
• Thermal expansion compensation through bellows and expansion joints
• Flexible support design to manage axial and lateral movement
• Robust material selection for high temperature and corrosion resistance
• Optimized flow dynamics for minimal pressure drop and turbulence

Types of Expansion Joints Used

• Pressure-balanced bellows
• Hooded expansion joints
• Tied units for controlled flexibility
• Angular and lateral combination joints
