A turbine casing is an external shell that contains and directs the working fluid, such as water or steam. Turbine casings are often made out of cast iron, cast steel or fabricated steel. Turbine casings play a critical role in the overall performance of the turbine, so it is vital that they are fully operational at all times. However, turbine casings are also subject to high heat and stress levels during operation which means that there are issues that can arise.
Leading on from this, there are a handful of issues that can arise with turbine casings that can impact the performance of the turbine and even stop it from working entirely. A few of the most common issues that are seen with turbine casings include:
Wear & Tear: Wear and tear is the most common issue with turbine casings. Continuous operation and exposure to high pressure super-heated steam and/or gases can cause wear and tear, which affects the overall integrity of the component.
Corrosion: Turbine casings are often continuously exposed to high levels of humidity. This can lead to corrosion that can weaken the turbine casing.
Cracks & Fractures: Cracks and fractures can occur as a result of thermal cycling, fatigue, and operational stress. These cracks and fractures can quickly grow, which can lead to extensive damage and complete failure.
Seal Damage: Turbine casing glands and seals can become damaged, which can result in steam leaks. These leaks can impact the efficiency of the turbine and increase the risk of damage to key internal components.

These days, turbines are integral part of all industries Here are a few of the main industries where turbine casings are found:
Power Generation: Both gas and steam turbines play an important role in power plants by producing electricity from energy produced by combustion gases or steam.
Oil & Gas: Turbines are used in the oil and gas sector to drive compressors, pumps, and generators in refineries and offshore platforms for energy production.
Marine: Turbines are used in the marine sector to provide power used for propulsion.

Metalock Engineering has expertise in turbine casing repairs for businesses in wide-ranging industries. We use advanced repair techniques that can quickly and efficiently restore your turbine casing to its original specification, helping you save money and prolong the life of your key industrial equipment.
We can usually carry out repairs on-site, which means that you do not have the cost and logistical challenges of dismantling your turbine and sending parts away for repair. This minimises disruption to your daily operation and helps keep downtime to a minimum.
We have a patented metal stitching repair technique that can be used to repair cracks and fractures in turbine casings. This is a cold repair technique, which means that there is no risk of warping or damage, which is common with welding repair techniques. This repair technique can restore the structural integrity of metal components and is far more cost-effective than buying new parts.
The worn or corroded areas within the turbine casings can be pre-machined to remove damage and wear, then built back up using either weld repairs or metal spraying repairs before being re-machined back to the original specification. These are very effective repairs that can be carried out in situ on diaphragm and blade locations, gland areas and split joint faces.
