Note:
Pressures listed above do not relate to the actual design pressure of the expansion joint products, but are the maximum surge or pressure for a specific control rod nominal pipe size.
302 Series
The Double Sphere has even greater compression, elongation and angular movement than the Single Sphere. It is constructed with the same attention to quality, and with the same materials, as the Single Sphere. However, it has greater acoustic resistance and dampens surge and shock due to its increased length and engineered shape.
