API 620 knock down tank. Bottom shell course –

An API 620 knock-down tank is a large, field-erected steel storage vessel designed for low-pressure applications, ideal for water processing and treatment facilities. Built in prefabricated plate sections that are shipped flat for efficient transport, the tank is assembled and welded on site. Its design accommodates various diameters and heights, with a robust bottom shell course providing strength to withstand the pressure of stored water. API 620 construction standards ensure durability, corrosion resistance, and compliance with industry requirements, making these tanks well-suited for clarifiers, process water storage, and other critical water processing uses.
