Emergency Online Leak Sealing at a prominent (2x800MW) Power Plant in India
Introduction
In this case study, we examine a critical incident at a (2x800MW) prominent power plant in India that faced a severe steam leak from a valve gland. The leakage involved steam gushing out at an extreme temperature of 300°C and a pressure of 150 bar. The immediate and efficient response of our online leak sealing team played a pivotal role in resolving this high-risk situation.
Incident Details
- Location: A prominent (2x800MW) power plant in India
- Issue: Valve gland leakage
- Conditions: Steam leakage at 300°C and 150 bar
Emergency Response
Our service engineers promptly responded to the emergency call. Upon arrival, they identified that the valve gland was exposed to high temperatures and water, causing the leakage.
Challenges Faced
The primary challenges included:
- High Temperature: The steam temperature of 300°C posed a significant risk to both personnel and equipment.
- High Pressure: The pressure of 150 bar required specialized handling to prevent further damage and ensure safety.
- Immediate Action Needed: The critical nature of the leak demanded an immediate and effective solution to prevent operational downtime and potential hazards.
Solution Implementation
Leak Sealing Compound: Our proprietary leak-sealing compound, NES-7A, was chosen to address the leakage. NES-7A is renowned for its effectiveness in sealing leaks under extreme conditions, such as high temperature and pressure.
Procedure
- Assessment: The engineers assessed the leakage and surrounding conditions to plan the sealing process.
- Preparation: Necessary safety measures were implemented to ensure the safety of the team and the plant.
- Injection of NES-7A: The leak sealing compound NES-7A was injected into the valve gland area. Its properties ensure a robust seal even under the harshest conditions.
- Monitoring: Post-injection, the area was monitored to ensure the leakage was arrested and no further issues arose.
Outcome
The application of NES-7A successfully sealed the leak. Key outcomes:
- Immediate Leak Arrest: The leakage was stopped promptly, preventing potential damage.
- Safety Ensured: The high temperature and pressure conditions were managed safely without any incidents.
- Operational Continuity: The power plant operations continued without significant downtime, showcasing the effectiveness of the solution.
Our expertise and prompt action ensured the safety of personnel and equipment, while maintaining the power plant’s operational integrity. This incident reaffirms the reliability and efficacy of our leak sealing solutions in the most challenging industrial conditions.
