EN 10025 S275J0 plates API 650 unanchored liquid-storage tanks

Ultrasonic testing can find the internal defects of API 650 unanchored liquid-storage 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 unanchored liquid-storage tanks and so on metal oil tanks. The feature of this method is convenient and fast.The thickness of the API 650 unanchored liquid-storage 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.API was established in 1919. It is the first national-level business association in the United States. It is one of the earliest and most successful chambers of commerce in the world to formulate standards. An important task of API API 650 unanchored liquid-storage tanks is to be responsible for API 650 oil storage tanks and natural gas. Standardization of industrial equipment to ensure the safety, reliability and interchangeability of equipment used in the industry.The company's business philosophy: customer satisfaction is the most important measure of our work performance; employees are the company's most important wealth; the improvement of employees' quality and professional knowledge is the growth of the company's wealth; employees' welfare and living standards are the concrete embodiment of the company's business performance; product and service quality are the lifeblood of the company's development; brand is the company's products and A mirror of service; recognition of the market is the foundation of the company's survival.The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, API 650 unanchored liquid-storage tanks and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.
