Valve Solution for Carbon Black Plant in Singapore
- Singapore
Customer/Owner: Carbon Black Plant in Singapore
- Working conditions/Challenges:
GEIH is a company dedicated to efficient energy and chemical material production. Their carbon black production line operates at extremely high temperatures, with some sections exceeding 425°C. The client needed a reliable valve control solution to ensure process stability and precise automated feeding in such harsh conditions.
- The type of equipment adopted:
We supply stainless steel valves that perform reliably under high temperatures, including gate valves, knife gate valves, and ball valves. For pipelines operating above 425°C, we have optimized valve structures and selected advanced sealing materials to ensure stable performance and long service life, even under high-temperature and high-frequency operation.
Key indicators: We also provide customers with intelligent electric actuators to achieve precise feeding control, assist customers’ production lines in realizing intelligent management, and improve system response speed and production line efficiency. Currently, we are cooperating with the GEIH engineering team to provide full-process valve design and selection services for its new production line, including technical parameter confirmation, selection suggestions, layout guidance, etc.
Achievements/advantages: The first batch of high-temperature valves has been supplied and put into operation.Customer feedback indicates good stability, and the operational efficiency of the production line has significantly improved. We are currently in the in-depth advancement stage of the new production line project and plan to introduce more intelligent control valves into the core sections.
