Professional static flange and valve sealing solutions
Three Major Sealing Challenges
1. Frequent leaks
Unplanned downtime for units 60% and above is caused by seal failure.
2. High costs
A single leak can result in annual losses amounting to hundreds of thousands of yuan.
3. Difficulty in Selecting the Right Model
Wrong choices lead to repeated failures.
