API 650 self-anchored flat-bottom steel tanks sheet and plate
Welded steel API 650 self-anchored flat-bottom steel tanks storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API 650 self-anchored flat-bottom steel tanks all adopt on-site production and installation of storage tanks.
The thickness of the API 650 self-anchored flat-bottom steel tanks annular bottom plates shall be in accordance with Table Q-4 (for steel or aluminum, as applicable). The thicknesses shown are minimums. The ring of annual plates shall have a circular outside circumference, but it may have a regular polygonal shape inside the tank shell with the number of sides equal to the number of annular plates. These pieces shall be butt-welded in accordance with Q.7.1.1, Item b. The plates of the first shell course shall be attached to the annular bottom plates by a weld as required by API 620 oil tank 5.9.5 except when a full-penetration weld is used or required (see Q.7.1.1). Butt-welds in annular plates shall be not closer than 12 in. from any vertical weld.
Ultrasonic testing can find the internal defects of API 650 self-anchored flat-bottom steel tanks welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API 650 self-anchored flat-bottom steel tanks and so on metal oil tanks. The feature of this method is convenient and fast.
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 uses outsourced logistics operations. Our cooperated professional third-party logistics providers use the advantages of large-scale production and cost advantages to achieve cost savings by increasing the utilization of resources in each link, so that we can benefit from the separation of cost structure. Therefore, we can also provide customers with better, faster and more efficient cargo transportation, delivery, and lower freight costs.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel API 650 self-anchored flat-bottom steel tanks 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.
