Small API Std 650 self-anchored storage tanks
Welding certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For both API Std 650 self-anchored storage tanks storage tank API 650, non-destructive inspection is required, but third-party inspection is not required.
Personnel organization before the construction of the API Std 650 self-anchored storage tanks:The company shall select technical personnel, quality inspectors and material personnel with organizational ability and construction management experience to participate in the API Std 650 self-anchored storage tanks project construction. The construction personnel shall arrive at the construction site before the designated commencement date, investigate the construction site, build construction facilities, plan the construction steps, and analyze the potential safety hazards during operation.
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.
The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)
Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the API Std 650 self-anchored storage tanks steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the API Std 650 self-anchored storage tanks steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the API Std 650 self-anchored storage tanks steel sheet on the truck Good luck.
