A gland leak on a valve operating in a high-pressure steam system is more than a maintenance issue. Apart from the continuous loss of steam and energy, an uncontrolled leak can create a serious personnel-safety concern and may progressively affect the surrounding valve components. At a major power plant in India, a severe steam leak […]
The Challenge A leading cement plant in India was experiencing severe abrasive wear on a section of its pulverised coal burner pipe. The pipe transports fine coal particles towards the combustion zone. Continuous exposure to fast-moving pulverised coal had gradually worn the pipe surface, particularly near the furnace-end section where the equipment was subjected to […]
A critical cooling water pipeline at a prominent refinery developed an active leak from a heavily corroded flanged connection. The line was operating at approximately 8 kg/cm² pressure and 50°C, making immediate intervention necessary to prevent further loss of cooling water and avoid disruption to plant operations. Visual inspection showed extensive external corrosion across the […]
The Challenge At a renowned refinery in India, a section of the plant air line had suffered extensive environmental corrosion following prolonged exposure to heat, moisture and outdoor operating conditions. During the initial inspection, Nicco Engineering’s Belzona service engineers observed severe deterioration across several sections of the pipeline. The original coating had broken down, exposing […]
The Challenge A power plant was facing a serious concrete deterioration issue on an external wall structure that had been in service for nearly 25 years. Over time, continuous exposure to the plant environment, elevated operating temperature, weathering, moisture ingress, and natural aging had caused significant degradation of the concrete surface. During inspection, the wall […]
A cooling tower at a leading industrial gas producing facility in India had developed a profuse leakage at the peripheral junction of the concrete wall and the outlet pipe section. The ongoing leakage created a maintenance concern for the plant and required a practical sealing solution that could be applied effectively on site. The application was carried out in 2025 for an industrial gas producing facility asset with a concrete & metal substrate. The Challenge Leakage […]
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 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 […]
