In high-temperature and high-pressure environments like pyrolysis plants, boiler pipe valve stability is critical for continuous production. Valve failure can cause production shutdowns and heavy economic losses. A company in Busan, South Korea, encountered such a problem, and WESDUN helped it quickly resume production.
Project Background: Urgent Valve Failure in Busan
A pyrolysis plant in Busan suffered boiler pipe valve damage, which caused an immediate production shutdown. As a core component of the boiler system, the valve failure threatened prolonged production downtime.
For a week, the customer searched extensively for suitable replacement valves but found none, due to the strict performance requirements for harsh operating conditions. Finally, they contacted WESDUN through a friend’s referral to seek a solution.
Working Conditions: Severe High-Temp & High-Pressure Challenges
WESDUN’s technical team clarified the key working conditions first to provide a targeted solution:
-
Working pressure: 3-4 bar, requiring excellent pressure-bearing capacity and zero leakage.
-
Working temperature: Up to 400℃ (short-term) and 380℃ (long-term), demanding high material stability and reliable sealing performance.
-
Application scenario: Pyrolysis boiler pipeline, requiring wear resistance and corrosion resistance to withstand medium scouring.
Ordinary valves could not meet these harsh requirements; the solution required high temperature resistance, high pressure resistance, reliable sealing, and long durability.
Solution: Double Eccentric Hard-Sealed Butterfly Valve
WESDUN provided a customized double eccentric hard-sealed butterfly valve, which perfectly matched the customer’s needs with three core advantages:
1. Product selection: The double eccentric hard-sealed butterfly valve minimizes friction between the valve plate and seat, and ensures zero leakage under high temperature and pressure through a hard metal sealing pair.
2. Special treatment: High-temperature resistant paint is sprayed on the valve surface to prevent oxidation and corrosion, thus extending its service life.
3. Efficient delivery: To meet the customer’s urgent need to resume production, the valve was produced and shipped to Busan within one month.
Project Outcome: Stable Operation & Loss Reduction
After installation and commissioning, the valve operated stably at a long-term temperature of 380℃ and a pressure of 3-4 bar, with no leakage. The boiler system and production line were quickly restored to normal operation.
WESDUN’s timely solution helped the customer avoid huge downtime losses (tens of thousands of US dollars per day if the issue remained unresolved). The customer highly recognized WESDUN’s professionalism and product quality, and designated us as their preferred cooperative supplier.
