An advancement from BE’s award-winning Retractable Packing systems, which incorporate coiled springs loaded between segmented packing rings and holder glands, Brandon™ Sensitized Packing provides optimal ring clearances across pressure stages for all operation phases of axial-flow turbine shafts.
Brandon™ Sensitized Packing improves upon conventional and Retractable turbine packing seal configurations by arranging spring loading to force ring segments inwards to a more preferable normally-closed orientation.
This improves packing gap clearance profiles within LP stages, end seals and during startup cycles, while retaining ideal gap spacing responses that contour to higher pressure operations, allowing BSP to be used alongside Retractable Packing, or standalone across all HP, IP and LP turbine stages.
Improved turbine efficiency and reduced maintenance costs.
1200+ units installed worldwide, creating long-term client partnerships.
Reduced steam leakage and plant heat rate improvements for lower operational costs.
Decades of expertise
ensuring the highest quality standards.
In addition to turbine shaft packing ring designs, BE orders and supplies coiled compres-sion springs for packing clearances from manufacturer to client, as spring strength, size and deformation specifications are custom to each turbine design.
BE provides spring kits for new designs, replacement orders for existing installations, as well as requested product documentation. With on-site spring inventory stocking for responsive lead times, we handle shipping directly to clients and purchasers.
Many conventional turbine packing systems offered minimal clearance adjustability or utilized non-contact packing clearance gaps.
Developed to address unwanted rotor rubbing and startup problems, BRP configurations retract to allow the ring gap spacing to increase in low pressure applications while retaining desired clearances to pressure differentials during standard turbine operating.
