Open-Top Storage / Frac Tank

ETC's 500 bbl portable storage tanks come in smooth wall or corrugated wall configurations. All have "V-bottom" floors for fast and easy cleanout. The long walls are made from continuous 40' sheets of steel that require only 4 weld joints. This feature greatly reduces the opportunity for leaks, cracks and hidden corrosion.
