The role of seals in the energy industry
Power plants (thermal, hydroelectric, nuclear, or renewable) require reliable sealing systems to prevent leaks in equipment exposed to high temperatures, extreme pressures, and aggressive fluids.
From gas and steam turbines to heat exchangers, electrical transformers, boilers, and wind turbines, seals play a key role in the efficiency, safety, and reliability of energy facilities.
Inadequate sealing can lead to energy losses, mechanical failures, and even accidents that compromise the operation of the plant.
SEALING
CHALLENGES
The equipment used in power generation operates under demanding conditions that require seals made from advanced materials and manufactured with high precision. Among the main challenges seals must meet are:
- High temperatures and pressures: Seals must withstand over 600 °C and up to 200 bar, especially in steam turbines.
- Fluid compatibility: Essential resistance to mineral oils, synthetic fluids, and dielectric fluids in transformers and hydraulic systems.
- Wear and load cycles: Continuous exposure to thermal and pressure cycles in valves and pumps requires high resistance to aging and fatigue.
- Corrosive environments: Seals must endure aggressive media such as molten salts or steam in solar thermal and geothermal plants.
RECOMMENDED SEALS
ENERGY SECTOR
Turbines and generators
FFKM O-rings designed to withstand extreme temperatures and pressures, offering excellent thermal and chemical resistance in demanding environments.
Thermal storage
PTFE or FFKM O-rings that withstand extreme temperatures and corrosive media in molten salt or thermal oil tanks.
Heat exchangers and boilers
Seals made of expanded graphite that ensure elasticity and tight sealing even under constant exposure to steam and thermal fluids.
Hydraulic systems and pumps
HNBR and EPDM O-rings resistant to wear, aging, and fatigue caused by continuous pressure cycles and contact with oils.
Wind turbines and mills
Large-size O-rings and V-Rings that provide protection against water, dust, and vibrations — essential in wind power environments.
Electrical transformers
PTFE or HNBR O-rings compatible with dielectric oils and stable under thermal variations, ideal for their durability.
