DuoSphere™ Gasholder structures are strong, lightweight and versatile. The high-strength fabrics, radio frequency welding process, and superior design make complex reinforcing cables or frameworks unnecessary. Because of this, installation is much simplified and heavy equipment is only required to set and adjust the level sensor.
