API 650 ground-supported liquid storage tanks fabrication requirements

Oil storage tank is an important equipment commonly used in petroleum and petrochemical industry. New API 650 ground-supported liquid storage tanks, metal storage tank must be tested before it can be put into use or put into storage. The common inspection methods of API 650 ground-supported liquid storage tanks include radiographic testing, ultrasonic testing, magnetic particle testing and dye penetrant testing. The parts and operation requirements of these testing methods are different, so they should be selected according to the required characteristics.The thickness of the API 650 ground-supported liquid storage tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 0.57 in. The nozzle neck is seamless steel pipe and conforms to ASTM A53, Grade A; the materials in the tank wall and reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank walls are fully radiographed, double-welded butt joints. The adequacy of the reinforcement and attachment welds shown in Figure F-7 shall be determined.
To determine the length of the nozzle neck within the limits of reinforcement, the smaller of the following calculated values shall be used:(2.5)(0.625) = 1.56 in.
(2.5)(0.375) + 0.75 = 1.69 in.There is a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API 650 ground-supported liquid storage tanks tank and the floating plate of external floating roof to ensure that there is no chuck during operation. Use API 650 ground-supported liquid storage tanks edge sealing system to reduce edge evaporation. The support legs of API 650 crude oil tank floating roof are usually movable and retractable and suspended in liquid.Continue to refine and improve the company's common core values.Corporate values are the evaluation criteria for the production and operation behavior, products, services provided, social reputation and credit of enterprises, the biggest API 650 ground-supported liquid storage tanks goal pursued by enterprises and the criteria for judging things accordingly, and the core of corporate culture. Companies in the extraction of common value note: simplicity; Unity of coordination; API 650 ground-supported liquid storage tanks Systemic; Respect for talents; Focus on giving back to society; Try to make a factual argument in order to gain wider acceptance.The company's products API 650 ground-supported liquid storage tanks have excellent quality, reasonable prices and strong usability, and are well received by users. Survive by quality, expand the market with integrity, continuously research and develop new products, expand varieties, to meet market demand, and make the company continue to grow.
