Highland Tank

API-650 vertical tanks are commonly used at oil and natural gas midstream facilities located along pipelines, at pumping, compression, or meter stations, and at natural gas processing plants. designs and fabricates aboveground shop fabricated steel storage tanks to API 650, Annex E, F, J and S standards depending on site requirements. This standard allows for the consideration of corrosion allowances, wind loading, and seismicity. The API 650 standard sets minimum requirements for design, material, fabrication, and testing for aboveground vertical, cylindrical, closed- and open-top, welded storage tanks in different sizes and capacities.

Our underground steel tanks provide superior structural strength and product compatibility. Designed to withstand the rigors of the underground environment, they are serviceable for storing of a wide range of petroleum products and other hazardous liquids. Tank dimensions and thicknesses are calculated in strict compliance with Roark’s Formulas for Stress and Strain as presented in UL-58. In addition, customization to suit your requirements is always available. A variety of industry-proven corrosion protection systems can be selected to be installed using a variety of backfill materials. Capacities from 240-60,000 gallons, exterior full fillet lap joints, striker plates under every opening, seam inspection, and 5 psi factory air test. Underground double-wall tanks are shipped with a vacuum on the interstice, eliminating the need for on-site leak testing
