By layering the cover rubber on the periphery, we ensure pressure resistance!
The "EMG Seal Cover" is designed to be installed retroactively around the outer circumference of existing rubber expansion joints without modifying the existing joints. The seal case, divided into sections around the circumference, is fixed to the existing flange using mounting brackets. By using and installing it in conjunction with rubber expansion joints used in large plants such as nuclear power plants and thermal power plants, it is possible to temporarily prevent water leakage caused by the rupture of rubber expansion joints during an earthquake. 【Features】 ■ Ensures the safety of pipelines ■ Capable of absorbing displacement during earthquakes (130mm) ■ Can be retrofitted (no modification of existing joints) *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Features】 ■ A structure that can be installed retroactively on the outer circumference of the existing rubber expansion joint without modifying the existing joint. ■ A seal case divided into sections around the circumference is fixed to the existing flange using fixed brackets. ■ The existing rubber joint and the seal case ensure watertightness with a lip seal (on-site joint), and a rubber membrane (on-site joint) that can absorb large displacements during earthquakes ensures watertightness between the seal cases. ■ By layering a cover rubber (with fabric) on the outer circumference, pressure resistance is ensured. *For more details, please refer to the PDF document or feel free to contact us.
