API Std 650 liquid-storage tanks stainless steel armored hose

API 650 petroleum storage tank stipulates that if the thickness of the lower siding obtained by calculating the anti-overturning moment is greater than the thickness of the API Std 650 liquid-storage tanks hydrostatic pressure test (both do not include the corrosion margin), the calculated thickness of the above siding required by the hydrostatic pressure is It should also be increased by the same proportion, unless special analysis is performed to determine the seismic overturning moment and corresponding stress at the bottom of each layer of API 650 petroleum storage tank wall.

Large Low-Pressure Tanks Corrosion Allowance
In cases in which the rate of corrosion is closely predictable, additional metal thickness over and above that required for the initial operating conditions shall be provided and shall be at least equal to the expected corrosion loss during the desired life of the tank.
When corrosion effects are indeterminate before the tank is designed (although they are known to be inherent to some degree in the service for which the tank is to be used), and when corrosion is incidental, localized, or variable in rate and extent, the best judgement of the API Std 650 liquid-storage tanks designer must be exercised in establishing reasonable maximum excess tank wall thicknesses. For all tanks that come under this classification, a minimum corrosion allowance of 1/16 in. shall be provided.

Natural ventilation loss: the main cause of natural ventilation loss is that the API Std 650 liquid-storage tanks is not tightly sealed. This is usually due to corrosion perforation on the top of the oil tank, or there is a height difference between the two orifices. The air tightness of the mixture in the API Std 650 liquid-storage tanks is higher than that of the air, which causes the mixture gas in the tank to be discharged into the atmosphere from the lower hole, and the external air flows into the tank from the high hole, resulting in natural ventilation loss.

The company always adheres to the concept of green production, follows the development path of innovation, transformation and improvement, and has carried out in-depth cooperation with Zhengzhou University and other scientific research institutes, planning from a high starting point, strict standard design, and successfully implementing engineering projects With nearly 20 research and development projects, the company's production technology and equipment are at the forefront of the industry, and indicators such as environmental protection, energy consumption, cost, and resource utilization have reached the advanced level in the industry.

The company's logistics and transportation department is responsible for developing high-quality third-party logistics companies, to coordinate and follow up the situation of steel materials transportation. Third-party logistics companies provide us with professional logistics services. With this logistics management method, the time for delivery of steel materials is faster, and the logistics service is professional, multifunctional and comprehensive.

Our quality and service commitment: API Std 650 liquid-storage tanks product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
