API Std 650 ground-supported liquid storage tanks shell manholes and nozzles

storage tank is used to store all kinds of liquid, solid and gas materials. The common types of storage tank are oil tank, water storage tank, chemical tank, cement tank, API Std 650 ground-supported liquid storage tanks, etc. When choosing the storage tank, users should choose according to their actual needs, such as the material, pressure, form, capacity, temperature, density, etc. In addition, the environmental factors such as the temperature of the tank construction area, the ground endurance of the foundation, and the wind force should be considered.The pressed-steel, round manhole with a 20-in. inside diameter shown in Figure F-8 is located in API 620 crude oil tank solid plate in spherical portion of a torispherical roof on a cylindrical storage tank 72 ft in diameter. The internal pressure, Pg, on the underside of the roof is 15 lbf/in.2 gauge. The thickness, t, of the roof plate required by 5.10.3 for the spherical portion of the roof is 1/2 in., which is exactly the thickness provided. No corrosion allowance is required. The materials in the oil tank roof plates and manhole frame conform to ASTM A283 Grade C steel; the main joints in the roof are double-welded butt joints, spot radiographed in accordance with 7.16 and 7.17.API was established in 1919. It is the first national-level business association in the United States. It is one of the earliest and most successful chambers of commerce in the world to formulate standards. An important task of API API Std 650 ground-supported liquid storage tanks is to be responsible for API 650 oil storage tanks and natural gas. Standardization of industrial equipment to ensure the safety, reliability and interchangeability of equipment used in the industry.Enterprise style: unity, pragmatism, responsibility, and endeavorOperation Policy: realistic management, innovative technology, high quality, fast efficiency, low cost and complete service.
