Fixed roof storage tank is a mainstream atmospheric/low-pressure storage equipment for petroleum, chemical and related liquid media.

It adopts an integrated fixed dome or conical roof structure with rigid connection between the tank body and roof, featuring stable sealing performance and reliable structural strength.

With simple structure, low operation and maintenance cost, and strong adaptability to storage capacity, it meets long-term closed storage demands of various liquid media, serving as a mature and standardized equipment in industrial storage.

Fixed roof storage tanks are manufactured with corrosion-resistant and pressure-qualified materials matched to stored media, with mainstream options as follows:

Carbon structural steels (Q235B/Q345R), suitable for conventional neutral media such as diesel, gasoline, lubricating oil and water, with high cost performance and excellent weldability;

Stainless steels (304/316L), providing superior acid and alkali resistance, ideal for corrosive or hygienic media including chemical solvents, food raw liquids, and weak acid/alkali substances.

Anti-corrosion coatings, cathodic protection and internal lining are also applied to further enhance aging resistance and medium erosion resistance, prolonging the service life of the tank.

Fixed roof storage tanks are mainly used for various liquid storage under atmospheric or low-pressure conditions, covering key industries widely.

Petrochemical industry: intermediate and reserve storage of crude oil, gasoline, diesel, heavy oil and other industrial oils;

Chemical industry: storage of stable liquid chemical raw materials at room temperature, such as alcohols, esters and additives;

Food and light industry: hygienic fluid storage including edible vegetable oil, syrup and drinking water;

Energy and municipal sector: fuel oil reserve, fire water tanks, supporting storage for municipal water treatment and other scenarios.
