API 650 carbon steel storage tanks lining

Unqualified welding quality of API 650 carbon steel storage tanks is prone to hidden dangers such as oil tank steel plate cracks and leakage. To avoid this situation as much as possible, it needs to be avoided when the oil storage tank is manufactured. Scientific and reasonable measures are adopted to control the welding quality when welding the API 650 carbon steel storage tanks. How to reasonably control the welding process quality of oil storage tanks?In this project, a cylindrical tank 62 ft 6 in. in diameter is designed for an internal pressure of 4 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 steel with appropriate grades for different plate thicknesses in accordance with Table 4-1 for a design metal temperature less than 65°F but not less than 25°F. No corrosion allowance is required for any portion of the tank. The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The roof is a single lap-welded spherical dome with an internal radius of 50 ft and a thickness of 1/4 in. The maximum design liquid level is 6 in. below the plane of the juncture of the tank API 650 carbon steel storage tanks roof and sidewall.Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API 650 carbon steel storage tanks floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.Our company has a strong, professional R & D team and advanced and perfect sales service concept, which makes our API 650 carbon steel storage tanks products have a high visibility and market share at home and abroad.
