The DM (Demineralized) Water Drainage Pipeline in a critical utility section had suffered extensive corrosion damage due to prolonged exposure to water and environmental factors. Upon inspection, NESL’s service engineers identified severe metal loss and pitting corrosion on both the inner and outer surfaces of the carbon steel line. Challenge Replacing the damaged section of […]
The Problem In a critical steam-handling section of a prominent power plant in India, a sudden leakage was identified at the bonnet of a 6-inch Non-Return Valve (NRV). The leak was discharging steam and condensate at 8 bar pressure and 180°C temperature, posing serious hazards to nearby equipment, insulation, and most importantly, operational personnel. The […]
In large-scale fertiliser plants, even a small flange leak can cascade into major safety, environmental, and financial consequences. When faced with an ammonia vapour and carbamate liquid leak at 75 bar and 170 °C, Nicco Engineering’s sealing specialists demonstrated how precise inspection, rigorous safety protocols, and the right sealing compound can arrest a critical leak—without […]
The Challenge A leading thermal power plant in India experienced severe wear at the bearing area of a coal mill shaft. Upon initial inspection, our service engineer observed: Significant material loss and surface degradation around the bearing zone Irregular shaft diameter causing potential misalignment with bearings Signs of accelerated wear likely due to abrasive conditions […]
The Challenge A major power plant in India encountered a critical maintenance challenge with one of its ACW pipeline components. The rubber expansion joint at the discharge side of the ACW pump had deteriorated severely. Constant exposure to extreme heat and environmental conditions had caused the rubber joint to crack, tear, and degrade significantly. The […]
At NESL, we pride ourselves on delivering cutting-edge solutions to complex marine Enviornmental challenges. Recently, our team undertook a critical project to restore a severely corroded conduit pipe and junction box on a ship without any hot work at the location, showcasing our expertise in fabrication, repair, and advanced coating technologies. This case study highlights […]
In the construction of storage tanks, wind girders (or stiffening rings) play a critical role. They prevent the tank walls from buckling under wind loads, especially when the tank is empty, ensuring structural stability and safety. However, when these girders are compromised by corrosion, the entire tank structure becomes vulnerable. The Challenge: A renowned chemical […]
The Problem A critical end suction pump used in a continuous service application suffered severe corrosion throughout its inner casing. Over time, the harsh operating environment led to pitting and rusting of the metal surfaces, significantly compromising the pump’s performance and efficiency. The client faced a pressing challenge: the need for a quick, cost-efficient repair […]
In the maritime industry, corrosion control is a constant challenge, especially for vessels exposed to harsh seawater environments. This case study covers the successful repair and protection of the stern pipe of the Coastal Sathwa vessel, demonstrating the importance of advanced repair materials and processes.
Introduction: The Urgent Need to Combat Corrosion Under Insulation (CUI) Corrosion Under Insulation (CUI) is a significant challenge for industries that rely on insulated piping and equipment, such as the oil, gas, and chemical processing sectors. CUI accounts for up to 10% of all corrosion-related costs in these industries and is responsible for 60% of […]
