Construction of API620 large steel storage tank

Construction of API620 large steel storage tank

The preparatory work before the construction of the API620 large steel storage tank is an important part of the oil tank project. Material purchase preparation before the construction of the API620 large steel storage tank:
Before API620 large steel storage tank construction, all materials shall be purchased and prepared, and the specifications and quality of materials shall be inspected to see if they meet the construction operation requirements. Fire and rain proof measures should be taken when storing materials. Paint should be stored in a ventilated and dry place.

The interior of API 650 storage tanks to be internally lined or coated must have all edges rounded to a minimum of 3 mm radius. Internal welds must be completely seal welded, ground smooth, and free from API620 large steel storage tank surface porosity, pockets, and high spots. Remove weld spatter. Vendor as specified on API 650 storage tanks drawing must perform additional surface preparation.

Except as permitted by API standard 620 Q.8.6, the test shall be conducted after the entire tank is complete, before the insulation is applied. Except as limited by foundation or stress conditions, the test shall consist of filling the tank with water to the design liquid level and applying an overload air pressure of 1.25 times the pressure for which the vapor space is designed. The load on the supporting foundation shall preferably not exceed the established allowable bearing value for the tank site. Where a thorough evaluation of the foundation justifies a temporary increase, the established allowable bearing may be increased for the test condition, but the increase shall be not more than 25%.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent API620 large steel storage tank products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the API620 large steel storage tank technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
