For narrow diameter pipe (less than 4” (102mm)) Chemigreen offers a specialized EPDM bladder having only a 1” (25mm) overall diameter. These bladders were specifically designed for protection against anhydrous ammonia spills, but can be used for any compatible chemical, water, or air protection.
As many as 16 of these narrow bladders may be connected to a single controller, operated from the same air supply, and requiring only a single point of operation and system maintenance.
