API standard 650 ground supported liquid storage tanks nozzles

Pressure Setting of Safety DevicesExcept as provided in API 620 tank 9.5 for certain liquid relief valves, the pressure setting of a pressure-relieving device shall in no case exceed the maximum pressure that can exist at the level where the device is located when the pressure at the top of the tank equals the nominal pressure rating for the tank (see API 620 tank 5.3.1) and the liquid contained in the tank API standard 650 ground supported liquid storage tanks is at the maximum design level.Vacuum-relieving devices shall be set to open at such a pressure or partial vacuum that the partial vacuum in the tank cannot exceed that for which the tank is designed when the inflow of air (or other gas or vapor) through the device is at its maximum specified rate.API 650 is the standard for welded tanks for oil storage. It specifies the API standard 650 ground supported liquid storage tanks design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI.In December, 2018, our Vietnam customer purchased 352 tons SA387Gr12Cl2 and SA387Gr11Cl2 API standard 650 ground supported liquid storage tanks steel plates for their tank fabrication project. The customer need those cargo urgently, and we keep many stock in warehouse , it only takes about 3days we collect total cargo for shipping to customer. The customer are very appreciate our quality and service. They API standard 650 ground supported liquid storage tanks become our regular customer and repeat order to us every month.All oil tanks have service life. Due to the pressure of the oil stored on the tank and the corrosion of the oil and external environment on the tank, the oil storage tank will gradually become thin or crack after a long time. Due to the different materials and environment of API standard 650 ground supported liquid storage tanks, the consumption of API standard 650 ground supported liquid storage tanks is different, so it should be taken into account when evaluating the remaining service life of API standard 650 ground supported liquid storage tanks.After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
