The Packing O-Ring is a sealing made from durable fluorocarbon rubber, designed for use in high-temperature and chemically harsh environments. Commonly used in gas turbines such as the LM2500 series, it provides a tight seal between components to prevent the leakage of fluids or gases.

This O-ring has an inside diameter of 27/64 inches, a thickness of 5/64 inches, and a hardness of 75 Shore A. It is built to handle operating temperatures from -20°F to 400°F, making it suitable for sealing joints in systems exposed to fuels, oils, and high pressures.

Its compact size and resistance to compression set and fluid exposure make it ideal for use in shafts, housings, and valve assemblies where reliable sealing is critical to turbine performance and safety.

The LM2500 exhaust system is an essential part of the LM2500 gas turbine, designed to handle the hot gases produced during turbine operation. Made from high-quality stainless steel, it is built to withstand extreme temperatures and harsh conditions, ensuring long-lasting durability.

The main purpose of the exhaust system is to safely direct these hot gases away from the turbine while reducing back pressure. Back pressure is the resistance the turbine faces when pushing out exhaust gases—lower back pressure means the turbine can run more efficiently, producing more power with less stress on its components.

This exhaust system is carefully designed to match the specific needs of the LM2500 turbine, ensuring smooth and efficient gas flow. It often works together with silencers or emission controls to release gases safely into the atmosphere while meeting environmental standards.

You would look for a new or replacement LM2500 exhaust system when installing a new turbine, upgrading to improve performance, replacing worn or damaged parts, or meeting updated environmental regulations. Choosing the right exhaust system is crucial because it directly affects the turbine’s performance, reliability, and maintenance costs. A well-designed exhaust system helps keep the turbine running efficiently and reduces the chance of costly downtime—critical factors for operations in oil and gas industries where reliability and efficiency are vital.

The Bearing, Roller, Cylindrical No. 6R is a precision-engineered component used in LM2500 aero-derivative gas turbines commonly employed in the oil and gas sector. Installed at the No. 6R position, this cylindrical roller bearing supports the turbine’s rotor shaft by carrying radial loads and maintaining accurate shaft alignment during high-speed operation.

Its specialized roller design allows it to withstand intense mechanical stresses and thermal changes typical in demanding oil and gas environments. By reducing vibration and ensuring smooth rotation, the bearing contributes to stable and efficient turbine performance, which is critical for continuous operation in upstream, midstream, and downstream applications.

The No. 6R bearing’s role in maintaining precise shaft positioning supports the overall durability and reliability of LM2500 turbines used in gas compression, power generation, and offshore platforms, making it a key element in sustaining safe and efficient operations within the oil and gas industry.

The LM2500+G4 SAC 50Hz Simple Cycle is a fourth-generation aeroderivative gas turbine of the LM2500. Designed for industrial power applications, including those in the oil and gas sector, it delivers more output and greater thermal efficiency while retaining the ease of maintenance and high reliability the LM2500 series is known for.

In a simple cycle configuration, the gas turbine generates power directly by expanding hot gases through the turbine stages, without recovering heat for additional power generation. This design is favored for its simplicity, lower capital cost, faster start-up, and suitability for mobile or remote applications.

The LM2500+G4 improves upon its predecessor by increasing airflow and turbine cooling capacity, allowing for higher operating temperatures. These changes result in up to 40% thermal efficiency in simple cycle mode—an impressive figure for this class of turbine. This translates to improved fuel usage and reduced operational costs over time.

The engine features a Single Annular Combustor (SAC), which supports stable combustion with low emissions of nitrogen oxides (NOx) and carbon monoxide (CO). The combustor is also designed for durability and long life, with easily replaceable fuel nozzles and a thermal barrier coating for resistance to high temperatures and corrosion.

Its two-spool design means the engine has no cold start limitations, making it well-suited for harsh or variable environments. The power turbine and gas generator can be separated, allowing for easier in-module repairs and less downtime.

Overall, the LM2500+G4 SAC 50Hz Simple Cycle offers a balance of power, efficiency, and maintainability, making it an attractive solution for power generation and mechanical drive needs in industrial, onshore, and offshore oil and gas operations.

The LM2500+G4 DLE U PT is a versatile gas turbine designed for a wide range of applications, including onshore and offshore power generation, gas pipeline compression, and LNG compression.

In the oil and gas industry, production rates are closely linked to available horsepower. The LM2500+G4 DLE U PT offers higher power output, high reliability, and a lower initial cost per kilowatt, making it a cost-effective solution for energy-intensive operations.

This turbine has proven its capability to operate reliably in extreme ambient conditions, with running data demonstrating performance at temperatures as low as -50°F and start-up capability down to -40°F. This wide operational temperature range ensures dependable service in harsh environments.

Fuel flexibility is a key strength of the LM2500+G4 DLE U PT. It can seamlessly switch between various fuels—lean treated natural gas, rich offshore gas, propane, or diesel—without shutting down or losing efficiency. This flexibility supports energy security, allowing continuous operation even if the natural gas supply is interrupted. Additionally, the turbine can be adapted to burn alternative fuels like bioethanol and naphtha, further enhancing fuel options.

A notable advantage of aeroderivative gas turbines like the LM2500+G4 DLE U PT is their ability to operate on hydrogen blends, which produce no carbon emissions when combusted. Both new turbines and existing units can be converted for high hydrogen fuel use, supporting decarbonization goals.

Moreover, the LM2500+G4 DLE U PT is truly dual-fuel capable, able to switch from 100% natural gas to 100% propane without the need for pilot fuels. This contrasts with dual-fuel reciprocating engines, which typically require about 5% diesel during gas operation, increasing costs and emissions. The LM2500+G4 DLE U PT’s fuel flexibility, emission controls, and robust design make it a reliable and efficient choice for demanding mechanical drive and power generation needs in the oil and gas sector.
