How Are Turbines Machined?

Industrial turbomachinery is essential to many power generation systems, including gas, steam, and hydroelectric power plants. These high-performance machines are designed to operate under extreme conditions, including high temperatures, pressures, and rotational speeds.

However, over time, even the most robust turbines can experience wear and tear, resulting in the need for repairs. Industrial turbines are machined during turbine repair operations to restore their performance and ensure their reliability. Read on to discover how our expert engineers at In-Situ Machining Solutions conduct this vital service globally.

What Is TurboMachinery?

Industrial turbomachinery refers to various equipment used in multiple industries to convert energy from fluids into mechanical work. This includes turbines, compressors, pumps, and fans, commonly used in power generation, chemical processing, oil and gas production, and other industrial applications.

As mentioned, turbomachinery is designed to operate at high speeds and pressures, often with complex geometries and advanced materials to withstand extreme conditions. It plays a critical role in many industrial processes, helping to increase efficiency, reduce energy consumption, and improve overall performance.

Turbine Machining Process

The process of machining industrial turbines during repair operations involves several steps. The first step is to disassemble the turbine and inspect the damaged components. Next, the components that require repair or replacement are identified, and the machining process begins.

The next step involves cleaning the components to remove any dirt, oil, or debris that may have accumulated during the operation. This is followed by using specialised equipment, such as on-site milling machines, to machine the damaged components back within OEM specifications.

The machining process involves the removal of material from the components, such as Journal Machining or adding new material with techniques such as laser cladding or electro plating. In some cases, components may need to be re-balanced to ensure that internal mechanisms rotate smoothly and without vibration.

Once the machining process is complete, the components are cleaned again to remove any debris generated during machining. The elements are then reassembled, and the turbine is tested to ensure it operates correctly.

Machining industrial turbines during repair operations is a complex and challenging process that requires highly skilled technicians and specialised equipment like the team we staff at In-Situ Machining Solutions. By restoring the performance and reliability of these critical machines, the machining process helps to ensure that the associated power generation systems will continue to operate efficiently and safely. Our teams have extensive experience conducting this essential machining service; read our related case studies to discover some of the many happy clients we’ve worked with over the years.

What Are In-Situ Repairs?

Choosing in-situ (or on-site) machining repairs for your turbine components offers several benefits over sending them away to a facility for repairs. The first and most obvious advantage is the reduction in downtime. When you send your components away for repairs, receiving them back will take weeks or even months. Your operations will be disrupted during this time, losing profits and productivity. With on-site machining repairs, however, the repair process can begin immediately, minimising any downtime and reducing the impact on your operations.

Another benefit of on-site machining repairs is the convenience factor. When you have your components repaired on-site, you eliminate the need for transportation, which can be a significant expense. Additionally, on-site repairs eliminate the need for disassembly and reassembly, reducing the risk of damage during transport or handling. On-site machining is more cost-effective than sending your components away for repairs, as you eliminate the additional costs associated with part transportation.

Adaptable Modular Repair Equipment

On-site machining repairs also offer greater flexibility when it comes to repair options. For example, when you send your components away for repairs, that facility may be limited in the services and capabilities of that facility. However, with our effective on-site machining repairs, the engineer will arrive with portable machining equipment to conduct the required work. This enables them to tailor the repair process to meet your specific needs, ensuring that the component is repaired back to manufacturer’s specifications and returned to operation as soon as possible.

Quick Results

Furthermore, on-site machining repairs provide the opportunity for real-time monitoring and inspection. The technician can monitor the repair process, ensuring everything is done correctly and to the highest standards. This monitoring level can help prevent potential issues or problems, leading to a more reliable and efficient component.

Essentially, on-site machining repairs can often be more cost-effective than sending your components away for repairs. With on-site repairs, you eliminate costs associated with part transportation, reduce the risk of damage during transport, and minimise downtime, leading to a faster return on investment.
