API Std 650 welded tanks for oil storage for small internal pressures

Oil tank is an important equipment for oil storage. The common API Std 650 welded tanks for oil storage is composed of foundation, bottom plate, wall plate, top plate and accessories. The types of oil tank are various, which can be divided according to the characteristics of material, installation position, storage oil, use, appearance, structure and volume of oil tank. The commonly used materials of metal oil tank are stainless steel, carbon steel, alloy steel, etc.

Impact Tests for High Alloys
Impact tests are not required for oil steel storage material nickel alloy welds made with electrodes/filler metals covered by AWS Specification A5.11 or AWS Specification A5.14, provided the nominal nickel content is 50% or greater, and the weld is deposited by the shielded metal-arc welding (SMAW), gas metal-arc welding (GMAW), gas tungsten-arc welding (GTAW), or plasma-arc welding (PAW) processes. When A5.11/A5.14 specifies the nickel content as a “remainder,” the nickel content shall be determined by summing the maximum specified values of the other elements (use the average specified value for elements with specified ranges) and subtracting from 100%.

Standard API 650 tank calls for calculations based on the specific gravity of the liquid product being stored. This permits the thickness of the steel API Std 650 welded tanks for oil storage needed as well as other specifications of how the tank is built to be determined by the weight of the API 650 tank.

On November 1st, our company organized some of company staff to visit Zhengzhou Children Welfare Institute, and gave children cookies and toys, as well as concerns to the Children. With the development of the society, disabled children gets increasing concerns and help from all walks of life. Fortunately, Chinese Government gives high concern to the handicapped children and has built Children Welfare Institutes all over the country to guarantee their lives.
