Double membrane gas storage can be installed on both in-situ concrete, precast, or suitable steel tanks. The external weather protection membrane serves to protect the internal gas membrane from the effects of the weather. The gas storage membrane is flexible and varies according to the amount of gas produced. The shape and color of these gas storage covers can be customized according to the requirement and customer\’s request. For fastening we use two different systems. The stainless steel U-profile with clamping hose system and the stainless steel double flat profile for screwing onto the wall crown.
