■ Prevention of broken-down and/or leakage of bellows by testable bellows with a detector (Preventive Maintenance)

A damage generated in the inner ply of the bellows can be detected without leaking to the outside, which thereby enable to use for a certain period of time after the leak is confirmed. It prevents emergency shutdown of equipment and ensures lead time for production of replacement products and improvement measures, which leads to various solution of problems. In addition, the multi-ply sealing structure protects corrosion of the outer ply with an inner layer, and extends the life. In important equipment such as FCC and SM equipment, testable bellows with a detector are recommended for stable operation, and we have many achievements in Japan and overseas.

■ Early restoration by the clam shell method as a temporary site repair (Corrective maintenance)

When the expansion joint is damaged, recovery is required in as a short period of time as possible. When the broken expansion joint is with lining for insulation and antifriction purpose and/or installed in a too narrow space to replace, the clam shell method is effective to repair. The clam shell method for the existing broken expansion joints support the safe operation till the next turnaround by the temporary repair at site
