In a refinery, a leak was detected on a 1-inch steam line operating under high-pressure service. The line was carrying steam at 130 bar pressure and 160°C temperature, making the leakage a serious operational and personnel-safety concern. Although the line size was small, the operating pressure made the situation critical. At 130 bar, even a […]
In a chemical plant, a major leakage was observed from a large-diameter flange handling ammonia vapour and carbamate liquid. The flange had an outside diameter of approximately 1.8 metres, with a significant gap of around 32 mm between the flange faces. The equipment was operating at 75 bar pressure and 170°C temperature. Due to the […]
In a chemical plant, leakage was observed from the bolted cover / flange region of a Hot Ammonia Separator. The equipment was operating under high-pressure service, with a process gas mixture containing Hydrogen, Nitrogen and Ammonia. The operating pressure of 150 bar made the leakage a critical maintenance and safety concern. Although the operating temperature […]
An engineered online leak sealing solution using an in-house designed and fabricated ring clamp and NES–2F high-temperature sealing compound. In a renowned power plant in India, a severely corroded bonnet flange on a 6-inch safety valve was releasing high-temperature steam and condensate through a circumferential gap exceeding 14 mm. With the system operating at 14 […]
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 […]
This case happened in a prominent refinery in India, During routine operations, a critical leak was detected at a welded joint on a Venturi Flow Transmitter (FT) line handling Propylene. The defect posed a high-risk scenario, as even a minor failure could have led to a complete plant shutdown, resulting in significant production and financial loss. Key technical details of the line were as […]
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 […]
A renowned 660MW power plant in India experienced a hazardous steam leakage incident. The affected line was operating at a high pressure of 140 bar, carrying steam at a temperature of 230°C. The leakage occurred on the body of the Turbine Driven Boiler Feed Pump (TDBFP) flange, posing a significant risk to the plant’s operations […]
When a prominent power plant in India faced a critical valve gland leakage, the situation demanded immediate and expert intervention. The leak, involving steam at a scorching 300°C and a pressure of 150 bar, posed significant risks to both personnel and equipment.
