Steel plate materials for API 650 stainless and carbon steel tank

The API 650 oil tank stiffener ring and backing strip, if used, are primary components, and they shall comply with the requirements of R.2.1. The API 650 stainless and carbon steel tank stiffener ring may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange. One rat hole with a minimum radius of 3/4 in. shall be provided at each longitudinal shell joint and ring juncture weld.API 650 internal floating roof oil tank executive standard: domestic design standard: GB50341-2003 "Vertical cylindrical steel welded oil tank design code"; domestic construction standard: GB50128-2005 "vertical cylindrical steel welded oil tank" Construction and Acceptance Specification; API 650 stainless and carbon steel tank Foreign design standard: API650-2007 "Standard for Welded Steel Petroleum storage tanks."In October, 2018, our Malaysia customer purchased 600 Tons CCS-AH36 Ship Building Steel Plates to use in their shipbuilding project .This customer is a famous shipyard in Malaysia. Their company has the business scope of tourism, API 650 stainless and carbon steel tank shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality . After visiting our factory, the customer are very satisfied with the quality of this batch of API 650 stainless and carbon steel tank CCS-AH36 Ship Building Steel Plates.The specifications used in the design of large oil tanks, API 650 stainless and carbon steel tank mainly include American Petroleum Institute Standard API 650, Japanese Industrial Standard JIS B8501, British Industrial Standard BS2654 and Chinese National Standard GB50341 from a global perspective. The formulas used in each specification are based on the hoop stress in the membrane theory. Each specification is based on the performance characteristics of materials and the construction technology level of their respective countries to determine the allowable stresses and weld coefficients. Therefore, the calculation results of tank wall thickness of API 650 stainless and carbon steel tank with the same volume are sometimes quite different according to different specifications.With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel API 650 stainless and carbon steel tank product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue.
