Shop-fabricated API standard 650 duplex stainless steel tanks

Density of API standard 650 duplex stainless steel tanks Liquid Stored
The density of the liquid stored shall be its maximum density within the range of design temperatures, but no less than 29.3 lbf/ft3 for methane, 34.21 lbf/ft3 for ethane, and 35.5 lbf/ft3 for ethylene.
Design Metal Temperature
The design metal temperature of each component exposed to the liquid or vapor being stored shall be the lower of the temperatures specified as follows: The design metal temperature of the components of the API 620 single-wall tank or the inner tank of a double-wall tank shall be the minimum temperature to which the tank contents shall be refrigerated, including the effect of subcolony at reduced pressure."API 650 petroleum storage tanks are used for API standard 650 duplex stainless steel tanks storage. API 650 petroleum storage tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature). Welding API standard 650 duplex stainless steel tanks certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For API 650 petroleum storage tanks, non-destructive inspections are required, but third-party inspections are not required.1200 tons API 5LGRB strips to Bangladesh. In December of 2015, we get one tender project from National Tubes Limited, which is a famous national enterprise in Bangladesh. It is an order of 1200 tons API 5L Gr. B steel strips, they bought these cargo to fabricate ERW pipe in local place.When the day light gradually decreases, the temperature of oil in the API standard 650 duplex stainless steel tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API standard 650 duplex stainless steel tanks will also decrease. When the pressure in the API standard 650 duplex stainless steel tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API standard 650 duplex stainless steel tanks through the open vacuum valve, which is the "suction" process of the oil tank.Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
