API 650 aboveground oil storage tanks appurtenances

The API 650 aboveground oil storage tanks most widely used and most commonly used standard for global storage tank construction and procurement is API 650. The Chinese translation name is "AP1650 Steel Welded Petroleum Storage Tank". API 650 storage tank is for commonly used oil, gasoline, diesel, chemical and production water storage, etc.

In cylindrical tank walls, the longitudinal weld joints in adjacent shell courses, including compression ring welds, shall be offset from each other a minimum distance of 12 in. The butt-weld around the periphery of a thickened insert plate, or the fillet weld around the periphery of a reinforcing plate, shall be at least the greater of 10 times the shell thickness or 12 in. from any butt-welded seam or the bottom-to-shell or roof-to-shell joint. As an alternative, the insert plate (or the API 650 aboveground oil storage tanks reinforcing plate in an assembly that does not require stress relief) may extend to and intersect a flat-bottom-to-shell corner joint at approximately 90 degrees.

The main reason of "small breathing" loss of API 650 aboveground oil storage tanks is the change of atmospheric temperature. When the temperature rises with the increase of solar radiation from dawn, the temperature of oil in the API 650 aboveground oil storage tanks also changes, resulting in the acceleration of evaporation speed and the increase of evaporation pressure. When the pressure exceeds the positive pressure rating of the breathing valve, the oil-gas mixture in the API 650 aboveground oil storage tanks is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.

Integrity, cooperation and innovation, positive and competitive, healthy and abundant are the company's core values. The company API 650 aboveground oil storage tanks always adhere to the "people-oriented", pay attention to improve the production skills and cultural quality of employees, by cultivating employees to carry forward excellent cultural traditions, set up the correct values, ethics and codes of conduct to improve employees' loyalty and work enthusiasm.

The main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
