API 650 special tank structural period of vibration

One of the most widely used design codes is the API 650 Standard, from the American Petroleum Institute. The main objective of this standards API 650 special tank is, through the requirements contained in its various sections, to facilitate the purchase and construction of vertical, aboveground, welded fabricated tanks assuring that required safety regulations are met.

BBN steel is a modern enterprise integrating scientific research and development, production processing, sales and service. The company now has finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. At the same time, it also adheres to international standards and adheres to the international line.

Inspection of low-pressure storage tank Butt-weldsComplete penetration and complete fusion is required (to the degree mandated by the acceptance criteria for examination method utilized) for welds joining tank wall plates to API 650 special tank tank wall plates. Examination for quality of welds shall be made using either the radiographic method specified in API 620 standard 7.15.1 and applied in 7.17, or alternatively, by agreement between the Purchaser and the Manufacturer, using the ultrasonic method specified in 7.15.3.1. In addition to the radiographic or ultrasonic examination, these welds shall also be visually examined as specified in 7.15.5. Furthermore, the Purchaser’s inspector may visually inspect all butt-welds for cracks, arc strikes, excessive undercuts, surface porosity, incomplete fusion, and other defects.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel API 650 special tank plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
