Emergency Valve Body Leak Sealing with NES-2C
In a critical scenario faced by a prominent carbon black manufacturer in India, a 6-inch 1500 class valve body experienced a severe leakage, releasing steam at a pressure of 150 bar and a temperature soaring to 200°C. To tackle this emergency, our service engineers swiftly intervened, employing a bespoke clamp fabricated as per ASME standards. This case study delves into the measured approach and successful resolution of the situation.
NICCO’s team of experienced engineers took immediate action upon discovering the valve body leakage. Recognizing the urgency of the situation, they deployed their expertise to implement an effective solution, preventing potential hazards and minimizing downtime for the carbon black manufacturer. Our engineers chose to enclose the leaking valve by a bespoke clamp to arrest the leakage completely.
Prior to fabricating the bespoke clamp at our workshop, NICCO engineers conducted meticulous measurements. Precision in these measurements was crucial to ensure the clamp’s compatibility with the valve body’s specifications and the severity of the leakage. This approach was essential in crafting a tailored solution for the specific requirements of the emergency.
Our inhouse design team adhered to the ASME standards while designing the clamp by our proprietary design software.
Our engineers opted for the NES-2C compound to address the critical valve body leakage. NES-2C is known for its efficacy in high-temperature and high-pressure applications. Notably, this compound is certified by the Bureau of Indian Standards (BIS), emphasizing its compliance with rigorous industry standards and safety protocols.
The bespoke clamp fabricated by NICCO included strategically placed injection points. NES-2C, the chosen compound, was precisely injected through these points to seal the leakage promptly. This targeted approach ensured the effective application of the sealant without compromising the structural integrity of the valve body.
Throughout the leak-sealing process, NICCO engineers prioritized safety. Rigorous safety protocols were adhered to, including the use of specialized personal protective equipment, implementation of confined space entry procedures, and continuous environmental monitoring. Regular safety briefings ensured that the team remained vigilant and well-prepared for potential challenges.
This case study serves as a testament to NICCO’s capabilities in providing swift and effective solutions in critical scenarios.
